Throughout the later stages of the spring season we probably will not be so excited to
see a Song Sparrow, but we all welcomed this herald of spring on Sunday morning.

Notes:  Despite a fresh blanket of snow that fell on Saturday evening, we were fortunate on Sunday to have the opportunity to band a final time during the winter monitoring season and bring our winter total of banded birds to 100.  Other highlights on Sunday included the first observation (and subsequent banding) of a Song Sparrow for 2007 and a considerable increase in the number of observed Ring-billed Gulls.  The first Red-winged Blackbirds of 2007 were seen on Friday afternoon.  With the winter monitoring season officially behind us, it is now time to begin spring migration monitoring, which gets underway with a census on March 28th!
