A new subspecies of Papasula booby is described from fossil remains collected in the Mascarene Islands of Mauritius and Rodrigues, southwestern Indian Ocean. The Mascarene Booby Papasula abbotti nelsoni ssp. nov., larger than nominate Abbott’s Booby P. a. abbotti from Christmas Island, northeast Indian Ocean, was approximately the same size as the extinct Hiva Oa Booby P. a. costelloi from the Marquesas in the Eastern Pacific. Mentioned in early accounts of Mauritius in 1668 and in 1725–26 and 1761 on Rodrigues, the Mascarene booby became extinct by the end of the 18th century. Members of another isolated but now extirpated population of Papasula abbotti from Assumption Island in the Seychelles Archipelago, the island from which the type specimen was collected, are identical to extant Christmas Island birds in size and colouration and discussed in detail herein.

The genus Baruscapillaria Moravec, 1982 has six valid species recorded in birds Phalacrocoracidae, namely Baruscapillaria appendiculata Freitas, 1933, B. spiculata Freitas, 1933, B. carbonis (Dubinin & Dubinina, 1940), B. jaenschi (Johnston & Mawson, 1945), B. phalacrocoraxi (Borgarenko, 1975) and B. rudolphii Moravec, Scholz and Našincová, 1994. Helminthological tests carried out on cormorants of the species Phalacrocorax brasilianus (Gmelin), a migratory bird that occurs in the northeast of the State of Pará, Brazil, demonstrate B. appendiculata parasitizing the cloaca of these birds, through light microscopy, scanning electron microscopy and molecular biology. These studies allowed a redescription of males and females of this nematode in these hosts and in this geographical area through integrative taxonomy. The occurrence of lesions in the cloaca caused by this nematode parasite was registered using histological analysis. This is a new geographic report for this nematode.

Genus Papasula Olson and Warheit, 1988 Papasula abbotti Olson & Warheit, 1988, p. 10 Type (by monotypy) Osteological diagnosis and comparison. The following osteological characters in combination characterize the genus Papasula. The fossil specimens are much larger than those of species in most other marine bird genera occurring in the Mascarenes, including those in Oceanitidae, Phaethontidae, Laridae, Stercorariidae, and in all Procellariidae except Macronectes giganteus. Papasula abbotti is smaller than M. giganteus and all species of Diomedeidae. It differs from similar-sized Fregata ariel and F. minor as follows. Coracoid: smaller, more gracile, and processus lateralis much less extensive. Sternum: larger; in lateral view, sulcus articularis coracoideus bordered with a much larger labrum interna and tuberculum labri externa; in dorsal view, foramina pneumatici larger, much more extensive. Humerus: more gracile, much thinner in the shaft and particularly lacks a sharply angular crista deltopectoralis. Ulna: much smaller; cotyla dorsalis larger and directed distad; impressio brachialis much more excavated; papillae remigales much less pronounced. Tarsometatarsus: most notably by much larger size, extremely reduced in length and width in Fregata, and sulcus extensorius much more deeply excavated. The Papasula material described herein is further assigned to Sulidae by the characters identified in Olson & Warheit (1988), Steadman et al. (1988), and van Tets et al. (1988), who also mentioned diagnostic characters of the cranial and other parts of the postcranial skeleton not discussed here.

Papasula abbotti, Cheke & Hume, 2008, p.47; Hume, 2013, p.216. Papasula sp., Hume, 2017, p.84. Holotype: Left humerus UMZC 262.AA (Figs. 4b, 5b) Measurements: (see Table 2). Type Locality: Mare aux Songes, southeast Mauritius (20826051, 200 S; 57841023, 500 E) Distribution: Mauritius and Rodrigues, Mascarene Islands. Etymology: Named after British ornithologist Joseph Bryan Nelson (14 March 1932 – 29 June 2015), who first recognised the presence of a Papasula booby on the Mascarenes, and whose ground-breaking studies on sulids and especially Papasula abbotti are still relevant today. Paratype: Left ulna UMZC 262.AA (almost certainly associated with Holotype), Mare aux Songes, southeast Mauritius (Figs. 6c, 6f). Referred fossil material: All collected from unspecified caves on the Plaine Corail, Rodrigues: coracoid NHMUK PV A9076 (Ld) (Fig. 2); cranial fragment of sternum NHMUK PV A9076 (Fig. 3); humerus (Lp) NHMUK PV A9049 (Figs. 4a, 5a); ulna MNHN 6574 (Rd); NHMUK PV A9076 (Rd) (Fig. 6); tarsometatarsus UMZC 995 (R) (Figs. 7b, 7c). Diagnosis: As for genus. Chronology: No dates are available from bird remains from the 19th century Mare aux Songes (MAS) collections (Basin 0), but 14C dates exist for MAS fossil remains of endemic giant tortoises Cylindraspis ssp., which became extinct c.1730, that were excavated from the same horizon as the Mascarene booby elements (Hume et al. 2021). The dates range from ca. 1260 to 1830 YBP (Burleigh & Arnold 1986). On Rodrigues, a partial humerus of the endemic owl Otus murivorus (Milne-Edwards, 1873), collected from 60–75 cm below surface in Caverne Dora on the Plain Corail, produced a radiocarbon age of 2850 ± 30 with a calibrated age range of 3060–2870 YBP (Burney et al. 2015). This suggests very low sedimentation rates in the late Holocene (Hume 2013; Burney et al. 2015). Although the precise cave from which P. a. nelsoni was collected is unknown, many of the caves on the Plaine Corail have depositional environments similar to that of Caverne Dora (Hume 2005, 2013). Description and comparison: Papasula a. nelsoni ssp. nov. differs from Papasula a. abbotti in being larger in all known elements (Appendix 1, Tables 1-4) and by the following diagnostic characters: Coracoid (Fig. 2b; table 1). In mediodorsal view, the proximal end is missing the tuberculum brachiale and facies articularis clavicularis, and sternally is missing the processus lateralis from the lateral point of labrum internum to margo caudolateralis on distal end. Nevertheless, it differs from P. a. abbotti on the dorsal surface by, impressio lig. acrocoracohumeralis broader and deeper; process on labrum externum larger, more prominent, with extension to distal corner of angulus lateralis more deeply excavated; in ventral aspect, facies articularis sternalis deeper, extending further laterad; in lateral aspect, facies articularis humeralis larger and wider extending further proximally. Sternum (Fig. 3; table 1). Only a small cranial fragment is preserved that includes two pairs of cranial foramina pneumatici and a single row (right side) of foramina pneumatici that follow the sulcus medianus sterni; it is missing the entire carina sterni and posterior part to processus craniolateralis including all processus costales. Differs from P. a. abbotti by, in dorsal aspect, tuberculum labri externa with more pronounced ridge on lateral edge; in lateral aspect, labrum interna and tuberculum labri externa larger, with sulcus articularis coracoideus deeper, creating a more pronounced undercutting of labrum interna; in ventral aspect, two cranial foramina pneumatici larger. Humerus (Figs. 4a, 4b, 5a, 5b; table 2). Holotype (UMZC 262.AA), collected on Mauritius, is complete with no erosional damage, whereas the Rodrigues specimen (NHMUK PV A9049) lacks around 66% of the distal end and much of the crista deltopectoralis. Differs from Papasula a. abbotti by, on caudal surface, tuberculum dorsale larger, more oval, and more rugose on distal surface; tuberculum ventrale larger and more robust, projecting more caudad and extending further mediocaudad; caput humeri more bulbous; incisura capitis more deeply excavated; margo caudalis more clearly defined proximally where it connects laterad to base of tuberculum ventrale; crus ventrale fossa more prominent proximally, especially at base of tuberculum ventrale; crista bicipitalis more convex without rightangled connection to shaft distally; fossa pneumotricipitalis larger, more deeply excavated with medial foramen pneumaticum much larger; sulcus humerotricipitalis more deeply incised, terminating in a sharp angle proximally; sulcus scapulotricipitalis more deeply incised, extending further proximally well beyond proximal level of sulcus humerotricipitalis; processus flexorius blunt, rounded distally, not angular; on cranial surface, sulcus lig. transversus deeply excavated medially, shallower laterally; crista bicipitalis more bulbous, without small distal crista; fossa m. brachialis more excavated; fossa olecrani larger; processus flexorius smaller, directed less medially. Ulna (Figs. 6c, 6f; table 3). Paratype (UMZC 262.AA), collected on Mauritius with holotype, is complete with no erosional damage, whereas the Rodrigues specimen (NHMUK PV A9076)is missing around 85% of the proximal end. Differs from P. a. abbotti in being longer, overall more robust; shaft less straight, more curved craniocaudally; in dorsal aspect, distal end more expanded; proximal pneumatic foramen larger; in ventral aspect, impressio brachialis more deeply excavated proximally; papillae remigales ventralis more prominent; sulcus intercondylaris deeper; foramen pneumaticum situated above sulcus intercondylaris and undercutting condylus dorsalis larger; presence of second foramen pneumaticum situated proximally on tuberculum carpale (absent in P. a. abbotti); depressio radialis more deeply excavated; in cranial aspect, cotyla ventralis narrower, more pointed; pneumatic foramen between condylus ventralis ulnaris and tuberculum carpale larger. Tarsometatarsus (Figs. 7b, 7c; table 4). Specimen missing crista medialis hypotarsi and plantar surface of trochlea metatarsi II and IV. Differs from P. a. abbotti by, in dorsal aspect, sulcus extensorius deeper proximally; incisura intertrochlearis lateralis and incisura intertrochlearis medialis slightly wider; tuberositas m. tibialis cranialis more marked, extending beyond proximal tip of lateral foramina vascularia proximalia; in plantar aspect, crista plantares lateralis more pronounced and lacking small foramen pneumaticum distal to crista lateralis hypotarsi; foramen vasculare distale much larger; wider and deeper sulcus on trochlea metatarsi III;medial surface of trochlea metatarsi IV more excavated, creating a pronounced crista extending proximal to crista plantares medialis; on proximal end, larger, otherwise similar to P. a. abbotti. The specimen figured (Fig. 8) in Milne-Edwards (1873) is the same specimen, but since that drawing’s execution, further damaged has occurred. For example, the crista medialis hypotarsi is now missing.

Antimicrobial-resistant bacteria pose a serious global health risk for humans and animals, while the role of wildlife in the dynamic transmission processes of antimicrobial resistance in environmental settings is still unclear. This study determines the occurrence of antimicrobial-resistant Escherichia coli in the free-living great cormorants (Phalacrocorax carbo) of the North and Baltic Sea coasts of Schleswig-Holstein, Germany. For this, resistant E.coli were isolated from cloacal or faecal swabs and their antimicrobial resistance pheno- and genotypes were investigated using disk diffusion tests and PCR assays. The isolates were further assigned to the four major phylogenetic groups, and their affiliation to avian pathogenic E. coli (APEC) was tested. Resistant E. coli were isolated from 66.7% of the 33 samples, and 48.9% of all the resistant isolates showed a multidrug resistance profile. No spatial differences were seen between the different sampling locations with regard to the occurrence of antimicrobial resistance or multidrug resistance. Most commonly, resistance percentages occurred against streptomycin, followed by tetracycline and sulfonamides. More than half of the isolates belonged to the phylogenetic group B1. Of all the isolates, 24.4% were classified as APEC isolates, of which almost 82% were identified as multidrug-resistant. These results add information on the dispersal of antimicrobial-resistant bacteria in wild birds in Germany, thereby allowing conclusions on the degree of environmental contamination and potential public health concerns.

Relationships between fish length and otolith length, width and mass were examined in the Australian anchovy Engraulis australis (White, 1790) recovered from the food of Gannet examined from colonies at islands of Horuhoru Rock and Mahuki Islands in the Hauraki Gulf, New Zealand. The relationships between otolith length- fish total length (TL), otolith-weight-TL, and otolith-width-TL were investigated by means of non-linear regression models (TL = 0.54 OL 16.86, TL = 4.39 OW 7.61 and TL = 26.19 OWe 2.2). This study characterizes the first reference available on the relationship of fish size and otolith size and weight for E. australis obtained from bird’s food in the Pacific Ocean region

Objectives Little studies had been done on chewing lice of marine birds in the Middle East. Through this work, parasitic chewing lice of Brown Booby Sula leucogaster (Boddaert) in the Red Sea were recorded for the first time from Egypt. Methods One brown booby was examined for chewing lice in Giftun Island, Hurghada. A total of 27 specimens of lice were collected from this bird and phylogenetic analysis of species of genus Pectinopygus associated boobies has been done based on NCBI data. Results and conclusions Two species of marine chewing lice were identified: Eidmanniella albescens (Piaget, 1880) and Pectinopygus sulae (Rudow, 1869) ; diagnostic remarks for the two identified species, measurements, and material examined were provided through the manuscript. The final phylogenetic tree indicates the monophyletic origin of Pectinopygus spp. associated with boobies and their paraphyletic relation to other species of Pectinopygus that associated with other Suliformes. Also, independence of boobies’ speciation from chewing louse of genus Pectinopygus speciation. The present work forms a small step in a long way of studying marine chewing lice of Egypt and a better understanding of marine birds/chewing lice interaction.

Recent genomic data sets have resolved many aspects of higher-level phylogenetic relationships of birds. Eleven phylogenomic studies provide congruent support for a clade formed by Procellariiformes, Sphenisciformes, Ciconiiformes, Suliformes and Pelecaniformes. This clade is here named ‘Feraequornithes’ following the rules and requirements of the PhyloCode.

The Neotropic cormorant Nannopterum (Phalacrocorax) brasilianus (Suliformes: Phalacrocoracidae) is widely distributed in Central and South America. In Chile, information about parasites for this species is limited to helminths and nematodes, and little is known about other parasite groups. This study documents the parasitic fauna present in 80 Neotropic cormorants’ carcasses collected from 2001 to 2008 in Antofagasta, Biobío, and Ñuble regions. Birds were externally inspected for ectoparasites and necropsies were performed to examine digestive and respiratory organs in search of endoparasites. Ectoparasites collected were cleared and mounted for identification under a microscope. Fecal samples were also evaluated to determine the presence of protozoan parasites employing a flotation technique. A total of 44 (42.5%) of birds were infested with at least one ectoparasite species, while 77 (96.25%) were carrying endoparasites. No protozoan forms were found after examination. Most prevalent endoparasite species found were Contracaecum rudolphii s. l. (72/80, 90%), followed by Pectinopygus gyroceras (33/80, 41.25%), and Profilicollis altmani (26/80, 32.5%). This is the first report of P. altmani, Baruscapillaria carbonis, Avioserpens sp., Cyathostoma (Cyathostoma) phenisci, and Eidmaniella pelucida in the Neotropic cormorant. These findings also expand the distributional range of Andracantha phalacrocoracis, Paradilepis caballeroi, Hysteromorpha triloba, and P. gyroceras to Chile. O Biguá Nannopterum (Phalacrocorax) brasilianus (Suliformes: Phalacrocoracidae) é amplamente distribuído na América Central e na do Sul. No Chile, as informações sobre parasitos para essa espécie são limitadas a helmintos e nematoides, e pouco se sabe sobre outros grupos de parasitos. Este estudo documenta a fauna parasitária presente em 80 biguás coletados de 2001 a 2008, nas regiões de Antofagasta, Biobío e Ñuble. As aves foram inspecionadas externamente em busca de ectoparasitas; adicionalmente, foram realizadas necropsias para examinar os órgãos digestivos e respiratórios em busca de endoparasitos. Os ectoparasitos coletados foram limpos e montados para identificação ao microscópio. As amostras de fezes também foram avaliadas para determinar a presença de parasitos protozoários, empregando-se uma técnica de flutuação. Um total de 44 (42,5%) aves estavam infectadas com pelo menos um ectoparasito, enquanto 77 (96,25%) estavam portando endoparasito. Nenhuma forma de protozoário foi encontrada após o exame. As espécies de endoparasitos mais prevalentes encontradas foram Contracaecum rudolphii (72/80, 90%), Pectinopygus gyroceras (33/80, 41.25%) e Profilicollis altmani (26/80, 32.5%). Este é o primeiro registro de P. altmani, Baruscapillaria carbonis, Avioserpens sp., Cyathostoma (Cyathostoma) phenisci e Eidmaniella pelucida no biguá. Esses resultados também expandem a distribuição de Andracantha phalacrocoracis, Paradilepis caballeroi, Ascocotyle felippei, Hysteromorpha triloba e P. gyroceras no Chile.

Objective: The abundance of Phalacrocoraxbrasilianus (Neotropic cormorant) was determined for the two climatic seasons of the year in the lagoon complex of San Marcos, Sucre, Colombia. Reproductive aspects are also discussed and the patterns of utilization that this species has for the work zone are determined. Methods/Statistical Analysis: The study area was the lagoon complex of San Marcos, Sucre, Colombia. We worked with two populations of P.brasilianus “Neotropic Cormorant” during the two semesters of 2016. The population registers were carried out through the method of constant observation for pre-established periods of time and fixed point of counting. The determination of the use patterns was worked through semi-structured surveys. Analysis of variance and significance test was applied to the population variables. Findings: The human consumption of this bird species begins to be evident in the study area; it is established that it is a resident population that has a significant reproduction during the first semesters of the year. The possible changes in density that can be observed during the two-semester of the year, are associated with the food supply, since the annual period. JanuaryJune is dry and the lagoons lose most of their coverage, which increases the concentration of fish, which is very important for this species. Application: The knowledge of the population variations through the annual period of a species offers valuable data that are important to advance in situ conservation programs, as well as to know the trend of use and the environmental or human stresses to which the species is subject. Keywords: Caribbean, Colombia, Density, Interior wetlands, Neotropical Cormorant, Usage patterns

Capturing breeding adults of colonially nesting species can entail risks of nest failure and even colony abandonment, especially in species that react strongly to human disturbance. A low-disturbance technique for capturing specific adult Double-crested Cormorants (Phalacrocorax auritus) at a ground-nesting colony was developed to reduce these risks and is described here. Nesting habitat enhancement was used to attract Doublecrested Cormorants to nest adjacent to above-ground tunnels constructed so that researchers could capture birds by hand. Using this technique, Double-crested Cormorants (n = 87) were captured during the incubation and chick-rearing stages of the nesting cycle. Unlike alternative capture techniques, this approach allowed targeting of specific individuals for capture and recapture, minimized local disturbance, and eliminated colony-wide disturbances. The tunnel-based system presented here could be adapted to capture adults or to access the nest contents of other ground-nesting...

International audience; We provide an up-to-date catalogue of the Coccomorpha Rubsaamen, 1899 of New Caledonia based on studies of collected and curated specimens and on the literature. One hundred and eighteen species (118) in ten families have been recorded to date, in 70 genera. Five of the genera (7.2%) are endemic, belonging to Asterolecaniidae Berlese, 1898 (Oacoccus Williams, 2007), Eriococcidae Cockerell, 1899 (Chazeauana Matile-Ferrero, 1988, Choneochiton Hodgson, 2014) and Monophlebidae Maskell, 1880 (Insulococcus Bhatti, 1991, Tessarobelus Montrouzier, 1864). Twenty-nine (29) species are endemic to New Caledonia, giving a rate of endemism of 24.6%. Most of the species are apparently human-assisted introductions. We provide here first records from New Caledonia for ten (10) species: Aulacaspis rosarum Borchsenius, 1858; Chrysomphalus pinnulifer (Maskell, 1891); Diaspis echinocacti (Bouche, 1833); Fiorinia phantasma (Cockerell & Robinson, 1915); Labidaspis myersi Green, 1929; Palmicultor browni (Williams, 1960); Poliaspoides formosana (Takahashi, 1930); Pseudococcus gilbertensis Beardsley, 1966; Pseudococcus orchidicola Takahashi, 1939 and Rhizoecus cacticans (Hambleton, 1946). Despite two introduction attempts for the biological control of weedy cactus, Hypogeococcus festerianus (Lizer y Trelles, 1942) is still considered absent from New Caledonia. Literature records of five species are shown to be erroneous: Dactylopius tomentosus (Lamarck, 1801); Dysmicoccus cocotis (Maskell, 1890); Lindingaspis buxtoni (Laing, 1927); Nipaecoccus filamentosus (Cockerell, 1893) and Clavaspis herculeana (Cockerell & Hadden, in Doane & Hadden, 1909), which are therefore considered absent from New Caledonia.

During the Neogene of South America, Anhingidae was represented by several species, mainly with greater sizes than the extant members. In the present contribution, body mass and locomotor habits of Anhinga minuta, the smallest known darter, were inferred. Body mass was estimated using two methods, one with measures of a tibiotarsus (the holotype) and the other, with measurements of a humerus; locomotor habits were inferred through muscular reconstructions and wing parameters (wing span, wing area and wing loading). Estimates of wing span and wing area were based on the length of humerus, assuming a condition of isometry with respect to Anhinga anhinga; wing loading was obtained through a relation formula between wing area and body mass. The results obtained indicate a body mass of about 729 g, a wing span of 0.958 m, a wing area of 0.117 m2 and a corresponding wing loading of 61 N/m2. These values and also the proximal insertion of the musculus pectoralis are consistent with those of a soaring bir...

El monitoreo de las aves varadas en las playas puede proporcionar información sobre sus causas de muerte, tales como la captura incidental en actividades de pesca o derrames de petróleo. Durante un año fue monitoreada mensualmente la Bahía de Coquimbo, norte de Chile para cuantificar el número de aves marinas varadas. Se encontraron 395 aves marinas muertas de las cuales 382 fueron identificadas y agrupadas en 21 especies. Las especies más abundantes fueron los piqueros con 115 individuos (30%), el cormorán guanay con 83 individuos (22%) y la gaviota dominicana con 65 individuos (17%). Las especies más abundantes y frecuentes fueron las que anidan en el Sistema Costero de Coquimbo. La mortalidad afecta principalmente a las aves marinas que se alimentan de la anchoveta, que es el principal recurso objetivo de la pesca con redes de cerco. Se sugiere que la mortalidad incidental causada por la pesca es crónica y relativamente constante durante el año. Se requiere un programa de monitoreo a largo plazo para mejorar la estimación de la mortalidad y los factores que influyen en la interacción de las aves marinas con las artes de pesca.

We reviewed the occurrences and distributional patterns of migratory species of birds in Brazil. A species was classified as migratory when at least part of its population performs cyclical, seasonal movements with high fidelity to its breeding grounds. Of the 1,919 species of birds recorded in Brazil, 198 (10.3%) are migratory. Of these, 127 (64%) were classified as Migratory and 71 (36%) as Partially Migratory. A few species (83; 4.3%) were classified as Vagrant and eight (0,4%) species could not be defined due to limited information available, or due to conflicting data. Fil: Somenzari, Marina.

Sulidae Morus capensis (VAG): breeds on the coast of southern Africa and in Namibia. It overwinters along the African coast west to the Gulf of Guinea,in eastern Mozambique, and exceptionally as far as Kenya. Most adult individuals remain in the waters close to the colony after breeding. Young individuals migrate north to the Gulf of Guinea (Carboneras, 1992). The species occurs occasionally in Brazil outside the coast of RS (Vooren, 2004) and SC (Olmos, 1997). Morus serrator (VAG): breeds in the east coast of Australia, Tasmania and New Zealand and there is also a small colony on Norfolk Island. It overwinters in waters adjacent to the east coast and in western Australia. Adults remain in areas around the colony, while immature individuals are more dispersive (Carboneras, 1992). There is only one documented record in the country for the Moleques do Sul Islands / SC (Bege & Pauli,1989; MNRJ 36164 [SC, 1987, June])., Published as part of Somenzari, Marina, Amaral, Priscilla Prudente do, Cueto, Víctor R., Guaraldo, André de Camargo, Jahn, Alex E., Lima, Diego Mendes, Lima, Pedro Cerqueira, Lugarini, Camile, Machado, Caio Graco, Martinez, Jaime, Nascimento, João Luiz Xavier do, Pacheco, José Fernando, Paludo, Danielle, Prestes, Nêmora Pauletti, Serafini, Patrícia Pereira, Silveira, Luís Fábio, Sousa, Antônio Emanuel Barreto Alves de, Sousa, Nathália Alves de, Souza, Manuella Andrade de, Telino-Júnior, Wallace Rodrigues & Whitney, Bret Myers, 2018, An overview of migratory birds in Brazil, pp. 1-66 in Papéis Avulsos de Zoologia 58 on page 37, DOI: 10.11606/1807-0205/2018.58.03, http://zenodo.org/record/5234679, {"references":["Carboneras, C. 1992 a.

The chewing lice (Insecta: Phthiraptera: Amblycera and Ischnocera) of Mexico have been little studied and many publications include isolated records. This paper summarizes current knowledge of chewing lice recorded from Mexico resulting from an exhaustive search of the literature published from 1866 to 2017. We found 342 louse species associated with 206 bird and 28 mammal species. As a result, we provide a checklist of the chewing lice recorded from Mexico, including a host-parasite list and their geographical distribution within the country.

Although the concept of optimal foraging has been extensively discussed, foraging efficiency is difficult to assess in vertebrates. In this study, we determined the foraging efficiency of the Brazilian cormorant,NannopterumbrasilianusGmelin, 1789, by the direct,ad libitumobservation of a group of four to thirteen individuals in an artificial pond at the University of São Paulo, Piracicaba, state of São Paulo, southeastern Brazil. Although this study was carried out in a highly anthropic environment, we can still conclude that the Brazilian cormorant is a relatively efficient browser and short-term diver. In anthropic environments, foraging success depends on the amount of time these birds spend diving, and stealing food is less common. Stealing occurs at relatively low rates but tends to be an efficient way to get food.

Reproductive timing in many taxa plays a key role in determining breeding productivity , and is often sensitive to climatic conditions . Current climate change may alter the timing of breeding at different rates across trophic levels, potentially resulting in temporal mismatch between the resource requirements of predators and their prey . This is of particular concern for highertrophic-level organisms, whose longer generation times confer a lower rate of evolutionary rescue than primary producers or consumers. However, the disconnection between studies of ecological change in marine systems makes it difficult to detect general changes in the timing of reproduction5 . Here, we use a comprehensive meta-analysis of 209 phenological time series from 145 breeding populations to show that, on average, seabird populations worldwide have not adjusted their breeding seasons over time (−0.020 days yr−1 ) or in response to sea surface temperature (SST) (−0.272 days °C−1 ) between 1952 and 2015. However, marked between-year variation in timing observed in resident species and some Pelecaniformes and Suliformes (cormorants, gannets and boobies) may imply that timing, in some cases, is affected by unmeasured environmental conditions. This limited temperature-mediated plasticity of reproductive timing in seabirds potentially makes these top predators highly vulnerable to future mismatch with lower-trophic-level resources Fil: Keogan, Katharine.

Diederle, J.M., 1.8.2015. Systematic status of the Miocene darter ‘Liptornis’ hesternus Ameghino, 1895 (Aves, Suliformes, Anhingidae) from Patagonia, Argentina. Alcheringa 39, 589–594. ISSN 0311-5518.Liptornis hesternus was established by Ameghino in the late 1800s on the basis of a cervical vertebra (NHMUK-A599) from the Santa Cruz Formation (Santacrucian, South American Land Mammal Age, early Miocene, Burdigalian Stage) of Patagonia, Argentina. Although taxonomic attributions were controversial, the specimen is now confidently assigned to Anhingidae. Recently, however, L. hesternus was designated a nomen dubium because of its uninformative diagnostic characters and apparent loss of the holotype. Nevertheless, NHMUK-A599 has been relocated and is redescribed here prompting referral to Anhinga. A combination of traits are shared with the extant Anhinga anhinga and A. melanogaster, and the material is dimensionally compatible with A. anhinga. The estimated body size of NHMUK-A599 would have been larger tha...
