Nashville Warbler and others in Canon City

The day started out quite foggy but became sunny in the late morning. I went to the east end of the Canon City Riverwalk when the fog burned off to see what might be there. I found a mixed flock of passerines including several Ruby-crowned Kinglets, a few Black-capped Chickadees, at least 2 each of Wilson's and Audubon's Yellow-rumped Warblers--and a rarity, a male Nashville Warbler.

The Nashville Warbler was so active, feeding in 2 hackberry trees, that I couldn't get a photo shot off (though I had my camera with me). Hackberry trees are great for warblers and other insect feeding birds, especially in the fall. Immature psyllids grow on hackberry leaves in the spring then cause "nipple galls" on the underside of leaves. The adult psyllid insects emerge from these galls in the fall providing a lot of bird food.
