What was most noticeable today was the absence. The absence of species that, not more than a week ago were around in large numbers. No Myrtle Warblers were encountered today; only 3 sparrow species; we had estimated totals of only 20 for American Robins, 40 for Cedar Waxwings. Overall, we encountered only 30 species for the whole day!? It’s staggering to think of the sheer avian biomass that has been on the move over the last few days and nights.
On the other hand, there were a few interesting phenomena: American Goldfinches continue to hit the feeders hard (and we’re getting recaptures of birds dated back to 2007; one was recaptured again in 2008 and not encountered since – I wonder what its personal trajectory has been); Rusty Blackbirds outnumbered Red-winged Blackbirds by about 3:1; and on census, Erich Bauer turned up 4 Ruffed Grouse – the first ones I’ve heard of in the vicinity of the Mansion (although I’ve encountered them across the highway well into the forest). Still, it’s clear: the mass of the migration is through and well south of us. We’ll continue on to Monday, November 7th but I predict diminishing returns (except maybe for goldfinches), although I’d like to be pleasantly surprised….
The Rusty Blackbirds really seem to like the forest that lines the stream running past the feet of nets 10, 2 and 4. They stay high until some brave soul drops down to the stream to drink or into the leaf litter on the forest floor to feed and then there’s a mad rush to join in and not miss any morsel. Consequently, when we catch them, we tend to catch them in bunches – as we did today with two small ‘hits’ in nets 2 and 4 (we banded 21 of them).
We had sort of a day off: no school classes. It was almost a holiday – just bird enthusiasts and birds……and home-made butter tarts (thanks Liz!)…..and doughnuts……

It felt great to be over there after all these months. I always enjoy the company and I always learn something new about our feathered friends.
Great that you guys could get out before the end of the season!
