Bluebird Trail

Bird House #1: (Above) The Mountain Chickadees (Poecile gambeli) don't look like they're doing very well. Today, there was only one live chick in there. Apparently the parents had hauled off the remainder of the egg shells and dead chicks. I think that there were originally six eggs. So, their survival rate is roughly what you'd see in a third-world country. Hopefully this chick makes it.

Bird House #2: (Above) This bird house is perched atop Jennifer's swing set. Yesterday, it contained two pink bird eggs. Today, it contains three pink bird eggs. Species unknown. Update: Based on photos on this website, I'm thinking that these eggs may belong to a pair of House Wrens(Troglodytes aedon).

Bird House #3: (Above) This bird house is mounted to the front garden fence. Yesterday, it contained three Bluebird eggs. Today, it contains four Bluebird eggs. This is either a Mountain Bluebird or a Western Bluebird. I believe that I saw the parents today and they appear to be Western Bluebirds.
Bird House #4: (Not shown) This bird house is mounted to the back garden fence. It is unoccupied.
Bird House #5: (Not shown) This bird house is mounted to a dead mature Ponderosa pine in the back. It contains seven tiny white bird eggs. No change from yesterday. Species unknown.

Bird House #6: (Above) This bird house is on a pole in Bud's front yard. At last count, she was sitting on six eggs, but she won't leave them now, so I'm not clear how many are under her or how many (if any) have hatched. This appears to be a nest of Western Bluebirds (Sialia mexicana).
