Występowanie w Polsce i rozpoznawanie "sokoła tundrowego" Falco peregrinus calidus
Journal Title: KULON - Year 2014, Vol 19, Issue
Abstract
Tundra Peregrin Falcon Falco peregrinus calidus is the Siberian subspecies of the Peregrine Falco peregrinus. It was recorded 13 times in Poland, including 5 immature individuals seen after 2000. This subspecies breeds in the arctic tundra, and winters mainly in Western Europe. A small number of records in the country probably results from difficulties in identification of these falcons rather than from avoiding Poland during migration. Diagnostic details are also given in the paper.
