Mountain Bluebird nest - oops, Tree Swallow nest!

Took this photo on 12th June, when I was invited by friend, Sue, to go with her when she did her Mountain Bluebird route out towards Bragg Creek. Each time she goes out, she has to record whether the nest belongs to a Bluebird or a Tree Swallow (occasionally something else such as a House Wren or a House Sparrow), how many eggs or babies there are, and then place a band around the leg of the appropriate birds. I was able to get a quick shot or two - sometimes, the nesting box is too high to see into to take a photo, so I had to hold my camera over the box, click, and just hope for the best, LOL.

Later: I had been wondering why there were a couple of feathers in this nest, as Bluebirds have featherless nests. Thought they might just have got in there by accident. I didn't have time to do a bit of reading on Google, as I drove out to the beginning of the mountains this afternoon to check on certain plants, but now that I have had time to look on Google, I realize that of course Mountain Bluebirds DO have blue eggs and so these are obviously Tree Swallow nest and eggs! Usually, they have a lot more feathers lining the nest. Sorry for the mix-up! Here is a link to a Mountain Bluebird nest, taken three years ago. I haven't figured out how to post a photo in a comment box with this new Flickr layout, only a link. farm2.static.flickr.com/1310/549298588_986aaa3a13_z.jpg
