Unusual Cordilleran Flycatcher nest location. Lyons, Boulder county

[Adrian Lakin (adrianlakin1@gmail.com)]

I was social distancing birding along Old South St. Vrain Road in Lyons with Rolf Hertenstein and Patrick Bohan this morning and we saw an unusual nest location for a Cordilleran Flycatcher. It was using an old Cliff Swallow nest. We've never seen this before. Anyone else witnessed this or other strange nest locations?

Adrian,

Very cool.  Thanks for posting.

Below is a pic of a male Canyon Wren arriving at its nest inside an old Cliff Swallow pot while swallows actively refurbishing the old hood look on.  This happened a few years back at Lory State Park w of FtCollins.

    

I wonder if these birds making use of old swallow nests are affected by swallow bugs, which are ectoparasites related to the human bed bug, and which reside in swallow nests.  Their accumulating numbers are part of the reason swallows often build new nests before each breeding season.

I have a similar photo of a House Wren occupying a Cliff Swallow nest I took at DeWeese Reservoir back during the Salida CFO convention.  It was singing very loudly and incessantly as they are wont to do and I imagined the neighbors being a bit miffed.

It's funny to see this post!!  Currently, I have a Cordilleran Flycatcher nesting in  my yard in west Lakewood.This is pretty rare occurrence for suburbia away from the foothills.  It is nesting in a fake Barn Swallow(the nest is to attract swallows) nest put under the eve of my house about 5 years ago. She is about on day 10 of the incubation of the eggs.The male comes by periodically to check on the female.  Pretty cool!!  See the attachments below:

Dave,

Here's a photo of a Canyon Wren in the same approximate location from August 30th last year where the wren was going between empty swallow nests presumably looking for bugs. Maybe the Canyon Wren clears out the bed bugs so the Cordilleran isn't bothered by them? It would be interesting to have seen what the Canyon Wren was catching.

I also have a Cordilleran hanging around our house this year and it's been around for about a month.  It may be nesting but I don't know where.
