Take a Second Look (TASL) Boston Harbor winter bird counts have been a part of the Greater Boston birding scene for a quarter century. TASL is what local birders do in November, when the masses of sea birds finally arrive in the Harbor. And TASLing is the way to pass the winter months, after the Christmas Bird Counts and the new year list blitz are over and done with. In this article, Maury Hall, the TASL data compiler for the past 17 years, sketches a brief history of the project. Maury then explains the basic techniques of the counts, presents summary data for TASL’s first quarter century, and provides brief accounts of water bird population trends or lack thereof.
