Fly Purple Martin Fledglings!
There has been a lot of action with the Purple Martins recently. They are finally fledging, after a very late start this year. Starting with 29 eggs, 23 hatched, and about 16 fledged. 7 of the babies died of apparent overheating, (despite our efforts to cool them with a home-made mister).
Looks like a fly was hitching a ride on one of their backs.
