White-crowned Sparrow, Gilbert AZ

Another common bird, the white-crowned sparrow is delightful nonetheless.

    Common you say ?!?!
    Did you know:
    “Scientists interested in movement and energetics have discovered that White-crowned Sparrows can run on a treadmill at a pace of about one-third of a mile an hour without tiring out. ”
    Other than a road runner, or an ostrich, that’s pretty uncommon(?☺).

    I wasn’t looking for that fact, but I came across it looking for something I read the other day about there being something unique about two slightly different versions (as it were) in breeding. But I can’t find it…..

    You caught a nice poise on the little guy too.
