September 19th – A Change In The Weather

The temperatures finally came down during the night accompanied by some light showers and a gentle northerly breeze. These factors brought in some birds – not huge number but nice variety. Yesterday we counted only 38 species around the site for the day; today we got 53 species, including the first Broad-winged Hawk and Purple Finch of the season. And although we banded only 30, this total was made up by 20 species.

Banded 30:

Fern Hill School Burlington:
Hi Rick,
We had a great day at FHB today. Once again a nice turn out of students eager to see the Fall migrants on their way south. We had an Estimated Total of 35 species throughout the day and we banded 15 including:

1 Tennessee Warbler

Wilson’s Warbler. -KAP

1 Wilson’s Warbler

Bay-breasted Warbler. -KAP

1 Bay Breasted Warbler
1 Common Yellowthroat
2 Black-capped Chickadees
2 Swainson’s Thrush
1 House Sparrow

White-throated Sparrow. -KAP

4 White-throated sparrow
1 European Starling
1 Blue Jay

We had two interesting recaptures today. The first was a Black-capped Chickadee originally captured in 2015 as a HY, and we haven’t caught it since 2016! We also caught a recaptured Chipping Sparrow that was originally banded in 2015 as an AHY. These mysterious birds always provide such rich discussion and food for thought for the students as they wonder where the birds have been this whole time, how they’ve survived, and how we can all help out our feathered friends.
