House Sparrow egg

Friend, Sue, very kindly invited me to go along with her a few days ago when she did her Mountain Bluebird route just west of the city. The majority of the boxes had Tree Swallows nesting in them, but some were occupied by Bluebirds. A few boxes were completely empty, some had a nest, some had a nest with eggs, some had a nest with a tight little pile of babies, and a couple had an adult Tree Swallow along with the eggs. And one box contained a nest of House Sparrow eggs, which are cream, white, gray or greenish, with irregular brown speckles. This one was being held by Kristin. It takes quite a bit of time to check and record all these boxes, and I respect all those who volunteer to have a route of their own. The House Sparrow nest was removed from the box as Mountain Bluebirds need as much human help as possible in order to protect their numbers.
