Migration Monitoring – April 8th and 9th, 2008

April 9th
It was a clear morning to start, but dark clouds moved in and I closed up shop after only 2 hours due to rain. Cold wet rain. I guess that goes without saying, but I feel better having said it.

Banded 3:
2 Black-capped Chickadees
1 Dark-eyed Junco

Retrapped 2:
1 Downy Woodpecker
1 Black-capped Chickadee


April 8th

Another warm, sunny day made it nice just to be outside wandering around – banding made it even better. There was a noticeable reduction in the amount of waterfowl traffic along the river. Duck numbers were down and geese were much less evident – 10’s versus 100’s. Three American Wigeon and 2 Northern Pintails kept it interesting though. Also, there was a small flock of 8 Bonaparte’s Gulls over the river feeding by picking something – emerging insects? – from the surface. They’re very agile and graceful birds.

We encountered 4 new species for the year: Common Snipe, Northern Flicker, Field Sparrow, and Fox Sparrow.
