Success! Didn't take long (2 minutes) to find the Blackpoll Warbler. And he was fairly cooperative. So got some nice photos.
The Blackpoll winters in South America and spends its summers across much of Northern Canada. Like most warblers their diet is mostly insects. But unlike most warblers they tend to perch in dense foliage near the tops of trees to forage. However, during migration they adapt to whatever the environment offers. Since Sweetwater provides excellent foraging opportunities in brush and small trees he is a little easier to find and photograph.
Here are a few of those photos:
