a stout branch on the east side of

just south of LSB with her bill full
of food. As soon as she landed on the
edge of the nest, young birds all were

mouth of the young & releasing the food.
Then she stood stationary at the edge of
the nest for several seconds, the young still

Then she placed a last morsel in another
youngster's mouth. When she finished this,
she settled down on the nest, just as if
she was incubating. When the ? appeared
on the ground about 25 feet north of the
nest with some food in his bill at
3:29 P.M., she flew out of the nest & back

to the nest with some food. She fed one
youngster again, then settled down on the
nest as before. At 3:39 P.M. she flew
out of the nest & traveled north-west.
