Publications about curiosities are known in the Hungarian and international ornithological literature since the 1800s. Although studies explaining the processes of pigmentation dysfunctions have been known since the mid-nineteenth century, these specimens still appear only as curiosities in the professional press and the terminology used to specify them is generally incorrect. The analysed genetic abnormalities causing white colour varieties in Woodcock (albinism, leucism, Ino) are due to mutations. By briefly describing the biological background of the defects, this work helps detect colour changes. In this article, we provide a broad overview of partially or completely white Woodcocks (n = 23 expl.) found in international (8 countries) and Hungarian literature. We have supplemented the literature background with our own studies. The large-scale analysis of the variability of colours and patterns was made possible by the countrywide wing sample collection within the biometric module of Woodcock Monitoring, which has been running under the coordination of the Hungarian Hunting Conservation Association since 2010. Within this framework, 12,078 samples were analysed between 2010–2018. We found that pigment deficiency occurred in the sample set only with a proportion of 0.01%. Based on the Hungarian literature and our own samples, we presented the known occurrences on maps of the state territory with boundaries before and after 1921, indicating the causes of patterns of occurrence by migration and frequencies of occurrence.

AbstractThe paper presents new records for 29 vascular plant species from 12 Eurasian countries. Seven taxa (Agave sisalana, Austrocylindropuntia subulata, Lagurus ovatussubsp. nanus, Opuntia stricta, Orobanche serbica, Oxalis articulata, Vitis × instabilis) are reported from Albania, one (Allium carinatum) from the Europaean part of Russia, six (Dipsacus fullonum, Gagea shmakoviana, Mentha × dalmatica, Thymus indigirkensis, Thymus sergievskajae, Viola × sukaczewii) from the Asian part of Russia, two (Agrostis sozanensis, Poa mustangensis) from China, two (Carex muskingumensis, Sedum rubens) from Poland, two (Crataegus macrocarpa, Dactylorhiza lapponica) from Romania, two (Oxygraphis delavayi, Ranunculus eryuanensis) from Nepal, two (Erigeron bonariensis, Ophioglossum vulgatum) from Tajikistan, one (Ranunculus olgae) from Kazakhstan, one (Najas guadelupensis) from Hungary, one (Orobanche bartlingii) from Armenia, one (Crataegus petrodavisii) from Azerbaijan and one (Amaranthus powellii) from Georgia. For each species, synonyms, general distribution, habitat preferences, taxonomy with remarks on recognition, and differentiation the species from the most similar taxa occurring in a given country, as well as a list of recorded localities (often far from the previously known areas) are presented.
