28 October 2010 – White-throated and Song sparrows

I found two sparrows this morning, a White-throated (fully dead) and Song (nearly dead).

Fat = 1, AHY-U

The Song Sparrow was still alive when I found it, but I was able to easily capture it by hand.

According to Dan Klem’s classic work, about 50% of the birds that are able to fly away from a window collision will ultimately succumb to their injuries. I don’t count “trapped” birds as casualties, but if I’m able to catch it, chances are its injuries are potentially life-threatening. In this case, I took the sparrow with me and carried it around for awhile until it had shaken the cobwebs off a bit. I released it near some juniper shrubs on the southwest side of Ag Hall, and it flew ~ 20′ into those shrubs. I will, however, consider it a “casualty.”
