Journal Title: KULON - Year 2013, Vol 18, Issue
Abstract
In 2010 and 2011, bird inventory was conducted in the Special Protection Area Przysowa and Słudwia valley (PLB100003). About 5 000 ha was under study, some areas beyond the SPA being included. The Area covers a fragment of the wet Słudwia valley and the total Przysowa valley with lake Szczawińskie. The present data are supplemented with archival materials from other years. In the period of autumn migration, concentrations of waterbirds in the Area reached a maximum of about 8 000 individuals (second half of November). In the third ten-day period of March, highest concentrations of geese Anser sp. (ca 22 000 individuals) were noted, including maximum concentrations of the Greylag Goose Anser albifrons of up to about 20 000 individuals and of the Golden Plover Pluvialis apricaria (ca 11 000 individuals). In 2013, flocks of the Bean Goose Anser fabalis of over 5 000 individuals were observed in the Słudwia valley. Among breeding species, the Black Tern Chlidonias niger (up to 50 pairs) and the Bluethroat Luscinia svecica (15-19 pairs) distinguished the Przysowa and Słudwia valley. Also the Montagu’s Harrier Circus pygargus nested abundantly (9-11 pairs). In the wet year of 2013, over 260 pairs of the White-winged Black Tern Chlidonias leucopterus were noted.
