THE WEEK: |

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!
