Some 263 birds were recorded near and in a 230-ha patch of semideciduous forest in cane fields of central São Paulo, Brazil. Subtracting 67 open-area species, 22 of marshes or creeks, 10 vagrants and 12 recorded later, 152 forest and border species were recorded in 1982-86, much like what was observed in a similar woodlot near Campinas. Both woodlots lost species gradually over the years. Some birds avoided hard cane-field edges, preferring soft bushy edges. Of open-area species, 22 seemed to have disappeared by 1997 due to earlier high El Niño rains or rare permanently open habitats in the sugar cane; 17 new species were mostly nocturnal ones not noted earlier, or occasional visitors. Forest and borders lost 31 species, gaining five of dry regions and one winter visitor. Several migrants from the south appeared only in wet years before recent greenhouse effects, some resident birds were hunted, and canopy hummingbirds were perhaps still present. Dry-forest travel-prone or "metapopulational" species moved their centers of distribution, partly concealing loss of moist-forest diversity.

El trepatroncos tiranino o "churulo" (Dendrocincla tyrannina, Dendrocolaptidae) de los bosques de neblina del norte de los Andes es solitario, como las otras especies del género. Se desplaza en el sotobosque lleno de epífitas, dependiendo parcialmente de los insectos que huyen de los escasos ejércitos de hormigas. Es un ave silenciosa y arisca, que se esconde después de volar cortas distancias en busca de presas, o procurándolas en musgos o troncos. La pérdida de los bosques húmedos andinos de laderas abruptas para dar lugar a la ganadería de baja productividad amenaza a la especie y aumenta el peligro de derrumbes en áreas sujetos a temblores; el uso más apropiado para tales áreas es para estudios científicos y actividades turísticas, y no para asentamientos permanentesThe Tyrannine Woodcreeper (Dendrocincla tyrannina, Dendrocolaptidae) of northern Andean cloud forests is solitary, like the rest of the genus, and wanders in the epiphyte-laden forest understory, depending partly on hard-to-find swarms of army ants and on understory flocks to flush insects. It is wary and silent, hiding after flying short distan ces for prey or gleaning it from moss or trunks. As los s of sleep Andean wet forests where the woodcreepers live resulls in gretaer danger from earthquakes, study and tourism are preferable to settlements.

Se presenta los datos morfométricos, muda, temperaturas cloacales y ectoparásitos de 123 individuos de 57 especies de aves colombianas. Morphometric data, molt, cloacal temperatures and ectoparasites are presented for 123 individuos of 57 species of Colombian birds.

We report Pelecitus helicinus Railliet & Henry, 1910 from 13 species of birds of 2 orders and 7 families, collected from the states of São Paulo and Mato Grosso, Brazil. All 13 constitute new host records for this nematode. In addition, we report the first record of Aprocta golvani Diaz-Ungria, 1963 from Brazil and Monasa nigrifrons (Bucconidae), as well as a number of other nematode records from Neotropical birds.
