Migration Monitoring after a rainy weekend – September 10th, 2007

If April showers bring May flowers, then September squalls bring…..Blackpolls!?

The rain of September 9th brought a fallout of migrants, dominated by Blackpoll Warblers, to Ruthven.There was much activity throughout the dayand the nets were kept quite busy. In fact, there was such a clamour to get banded that one enterprising young Common Yellowthroat eschewed the nets all together and flew right in to the banding station by itself…where it promptly changed its mind and flew out again. In reality I think it was attracted by the calls of another Common Yellowthroat in one of the bags hanging up, for the bird flew in through the door, alighted on the bag and then flew out again. Possibly a family member? Anyways, I quickly banded and released the bagged bird (HY-U).

Many of the migrants were in “worn” shape with little to no fat and muscle counts of predominately 2.

  1. Seeing that would have been worth skipping work and pissing a whole bunch of people off. A great day!

  2. Wow! It’s very unusual for us to get a 100+ day at Ruthven until the very end of September/1st three weeks of October. The Connecticut Warbler would be the 1st for the year. Nice going Brian!
