Well....so much for grand notions of seeing a 'possible' Snowy Egret.
On my way home from work I stopped by the stream crossing just south of
Cheese Factory Rd on Rt 116 (South Burlington). There was a single
Egret fishing down stream of the beaver dam (my guess is it is probably
the 'small' bird I reported this morning (via Ken)). The upper mandible
was partially dark but also partially yellow (overall it was darker than
any of the Great Egrets I have photographed elsewhere). The lower
mandible was definitely yellow. I only saw a flash view of feet but no
yellow was seen. It lacked the neck tufts that are typical of a Snowy.
I am now confident it looks a much more like a Great Egret than an
implausible Snowy. Lesson learned: I will keep binoculars in the car
from now on.
