During 2011, the Brookline Bird Club listed 302 species of birds on 197 reported trips, three more than last year. A total of 224 trips were scheduled,twomore than last year but 66 fewertrips than the all-time high number of 290 in 2000. There were 49 all-day, 144 morning, 18 afternoon or evening, ten pelagic, and three weekend trips. There were also two impromptu trips organized for reported rare birds–one was successful in adding a new species to the overall Club’s list.

On May 18 Ida Giriunas led a small group to search for the FIRST state record of Cassin’s Sparrow. The normal range for this sparrow is in the western United States grasslands. The sparrow arrived during a period of northeast winds and remained in the area for five days. Ida and her team added this to the overall Club list with a day to spare before it disappeared. Sylvia Martin, on the other hand, was a day late when on April 19 she led an impromptu trip to Hyannis in search of just the second state record of a Yellow-legged Gull.

Thirteen trips were not reported, and an additional 13 trips were cancelled by weather. In Massachusetts the Club listed a total of 291species, three more than last year. To put this in perspective, birders throughout the state recorded a total of 363 species during the year; thus the BBC total of 291 is 80% of all the species seen in the state in 2011!

Two new species were added to the overall Brookline Bird Club list of birds, a Cassin’s Sparrow that was discovered on the impromptu trip on May 18, and a Brown Booby from Provincetown on day thr
