This year we heard of reports of an American Redstart near the Audubon Center at Chatfield. During a late afternoon in early June, we headed down to the Audubon Center to see for ourselves; we did find a nesting pair. Later when returning back to our vehicle, we stopped off near the Center. Here we found a Tree Swallow perched on the roof of a bird feeder.
After a while, we noticed a second Swallow flying close by, so I decided to approach closer to capture this image of the female bird on the feeder roof.
Soon it became apparent that this was a breeding pair; the male bird flew in.
And began mating with the the female.
This continued several times over the next 15 minutes that we were there. Here is another image of the male flying in.
I made several images of the mating pair before we returned home.
We were both fortunate to see this mating display as well as the nesting Redstart!
