Bluebird Trail - 6/13/10
.jpg)
Above: Box 3 - Mountain Bluebirds - Mom laid 5 blue eggs and began incubation on 5/30/2010. I'd say the eggs hatched on June 13th.

Above: Box 4 - House wrens - 6 pink speckled eggs. Not clear if incubation has started yet. I've never seen mom on the nest.

Above: Box 7 - Tree swallows - 4 white eggs. Tree swallows finally made a nest out of feathers after I left town. No sign of incubation, but at least 4 white eggs in the nest.

Above: Box 8 - Western Bluebirds - Mom laid 6 blue eggs and began incubation on 6/1/2010. 5 eggs hatched on June 13th. 1 egg still not hatched when I checked today. Mom not on nest.
Box 1 - House wrens - 0 eggs. This is a decoy nest.
Box 2 - House wrens - 0 eggs. This is a decoy nest
Box 3 - Mountain Bluebirds - 5 blue eggs. Mom on nest. I'd say she officially began incubation of 5 eggs on 5/30/2010. Assuming an incubation period of 13-15 days, her eggs should hatch on June 12-14. I checked today and she was sitting on at least two live chicks. I'd say the eggs hatched on June 12-13th. We'll call it June 13th.
Box 4 - House wrens - 6 pink speckled eggs. This nest has straw in the nest of twigs, indicating that the nest was completed, but no eggs were ever laid until after I left town. Now, there are are least six eggs in the nest.
Box 5 - Mountain Chickadees - 7 white eggs. Mom was incubating the eggs when I left, but I didn't see her today. The eggs were uncovered and she wasn't on them. Assuming an incubation period of 12-14 days, her eggs should hatch on June 13-15.
Box 6 - House wrens - 3 pink eggs. This nest has been abandoned, and I noticed a hole in one of the eggs today. Perhaps Timmy got the mom.
Box 562 - Mountain Chickadees - 7 white eggs. Mom still on the nest. Unknown if any have hatched. She officially began incubation of 7 eggs on 5/30/2010. Assuming an incubation period of 12-14 days, her eggs should hatch on June 11-13.
Box 7 - Tree swallows - 4 white eggs. Tree swallows finally made a nest out of feathers after I left town. No sign of incubation, but at least 4 white eggs in the nest.
Box 8 - Western Bluebirds - 5 baby Western Bluebirds and one unhatched blue egg. Mom not on nest when I checked.
Mountain Bluebird eggs laid: 5
Western Bluebird eggs laid: 6
House Wren eggs laid: 9
Mountain Chickadee eggs laid: 14
Tree Swallow eggs laid: 4
Total eggs laid: 38
Mountain Bluebird chicks hatched: at least 2 - possibly as many as 5
Western Bluebird chicks hatched: 5
House Wren chicks hatched: 0
Mountain Chickadee chicks hatched: 0
Tree Swallow chicks hatched:
Total chicks hatched: at least 7 - possibly as many as 10.
I was incorrect on my assumption that all eggs had been laid by June 1. The wrens continued to lay eggs in June, as did the Tree Swallows.

It's a pity that not all eggs are being hatched as predicted. There are other factors that can interfere in these circumstances.

I'm sure he's pleased. He's been slaying quite a few birds. My bedroom floor looks like the floor of a chicken coop.
