It may also be that parental phoebes attempted to dislodge cowbird shells and some were able to do so. |
I was sure the cowbird, a female, was targeting the phoebes, and apparently they knew it too. |
I can only assume from the brazen behavior of these phoebes that they were protecting a nest. |
He tied silver cords around the legs of a group of phoebes, and spotted two of the banded nestlings when they returned the next year. |
Since we've identified plenty of phoebes in the field, I'm inclined to take this bird as a pewee. |
I thought it looked large and had a white chest and speculated it was one of the you phoebes that are hanging around. |
