Am Dippers at Clear Creek and Lowell, Adams County May 7, 2020

[Robert Canter]

Hi CoBirders

I was able to see two American Dippers this morning in Clear Creek, just east of the Lowell Blvd. bridge. They were very lose to each other at times and I could see an evident size difference. When the larger bird approached the smaller, it would dip and flair its wings. It didn't attempt to forage or enter the stream very much. The smaller bird foraged actively. I saw both birds enter the  nest hole in the wall on the south side of the creek, sometimes carrying grass into it. I didn't see any young in the nest. Other birds observed at this spot: Canada Goose, Mallard, Barn Swallow, Am. Robin and House Sparrow.

Thank you, Bob Canter, Denver
