This Sunday was a
bird banding at Ritter Farm Park in Lakeville, MN. It was a pretty location, and I got several species firsts and some great shots all around. First up here was the most common bird of the day, a Tennessee Warbler.
Tennessee Warbler: Vermivora peregrina.

Note the color here, it is a beautiful olive-green on its back.


Early in the day, we were thrown off by the extremely yellow throats, as shown here:

At the same time we pulled that one out of the net, I caught another one apparently feeding from the nearby plum blossoms. Not sure if they were going just for the nectar, or for bugs or something else that was feeding there, or maybe they just thought the bees were slacking and needed help pollinating.



So, that does confirm that it was just a whole lot of pollen on them. It showed though that even with a bird in-hand, there are external factors that can change the apparent color of the bird.
