Tree swallow pair
观察细节
In flight over marsh and flooded agricultural fields. Perching on tops of a few dead trees, one pair perching together. In a large dead tree, tree swallows may be nesting--the opening would have been on the far side of the trunk so I could not see it, but I could see a tree swallow's tail, then head, as if it was going in and out. At times, 3 or 4 tree swallows seemed to be fighting over this territory (one head visible from the tree trunk, 2 or 3 others flying around outside with lots of noise).
