By excavating their own nests Northern Flickers provide nests for other woodland birds that can't excavate nesting cavities on their own and those nests can be used over and over again. Nature is brilliant.
Two days ago I spent time photographing nesting House Wrens in the high Uintas near Mirror Lake Highway, of interest to me is that two years ago I photographed Red-naped Sapsuckers using this same nesting cavity.
Last August I was a bit surprised to see a House Wren at Bear River Migratory Bird Refuge from the auto tour loop around the marshes there.
Male American Kestrels look for and locate potential nesting cavities within their territories and inspect them prior to the nesting season.
A month ago I photographed a pair of Williamson's Sapsuckers excavating a nesting cavity in Idaho and this past week I spent several days photographing them again.
For a few days now I said I was going to do a post about the House Wrens I photographed at the same nesting tree as the Williamson's Sapsuckers, here it is.
I want to thank Neil Paprocki for sharing information about Al Larson and the upcoming film The Bluebird Man, I have learned a lot from the web site and through my interview with Neil and I am all for learning more about the wonderful natural world around me.
