Ring-billed Gull

Larus delawarensis

UP: You are seeing a range of eight middle-sized gulls: the first seven are Common [Mew] Gulls (Larus canus), while at the right end there is an adult Ring-billed Gull (Larus delawarensis). Note the sligthly clearer mantle, stocky shape and absence of white at the scapular tips. Mantle color is similar to the Black-headed Gull (Larus ridibundus) at the top right. Chioggia, NE Italy, 22-Jan-2001.

DOWN: Both Common Gulls and the Ring-billed feed daily during lowtide by picking-up the algae from the mudflat, searching for little fish, crabs or shrimps (see top of the photo), while Black-headed Gulls prefere picking food by swimming on shallow water (see bottom). The Ring-billed Gull (first or second for Italy, if accepted) was found by Menotti Passarella on 18-Dec-2000, and again on 23-Dec-2000, 6-Jan-2001, 22-Jan-2001, 3-Feb-2001 and 12-Feb-2001.
