and at Auschwitz, outside of Krakow, Poland. At Auschwitz we were feeding them bits of bread from our sandwiches.

In summer, the adult has a chocolate-brown head, a pale gray body, black tips on the primary wing feathers, a red bill and red legs. 

The distribution, set forth below, is quite wide, including most of Europe, and other widely scattered spots, including rare visits to eastern North America.
