235. Baolophus bicolor Tufted Titmouse, “blue-

often during the spring migrations, especially Feb-

dates for every month in the year in Honeybrook 
and Nantmeal Twps. Jackson informs me_ that 
it undoubtedly breeds along the Brandywine below 
Downingtown, but he has never actually located its 
nest. Pennock, apparently, has found it breeding 
but gives no dates; “Thomas found a nest at Kennett 
Square in the summer of 1908, date not recorded.
