Migration Monitoring – October 9th & 10th, and a few pictures

October 10th
Election day in Ontario, and the Yellow-rumped Warblers must have mistaken Ruthven park for their polling station. Scads of them dropped into the park at dawn. I collected 25 Yellow-rumps in the first net round, and then with the wind and swirling leaves, I decided to close the nets. If banding conditions had been better, I’m sure I could have banded 50 more, for it was one of those days where you could hear their call note everywhere, all morning long.

Banded 52:
1 Black-capped Chickadee
3 Ruby-crowned Kinglets
25 Yellow-rumped Warblers

October 9th

A warm 19 degrees at opening. The stars were out but there were no overhead call notes. Shortly after daybreak a light breeze picked up from the north and, voila!, instant fog (that stayed around most of the morning). There were ‘patches’ of birds around but nothing in big numbers. [However, if we had the competent personpower to run the long #8 net chain down to the river across the flats, we would have picked up a lot more birds as there was a lot of activity along the river.]

A highlight for me was that we only had to band 1 American Goldfinch.
