Cliff Swallow
24.
Bridge 3mi. N.E. of Davis, Yolo Co., Calif.
This bridge (Poleline Bridge) is again
used by swallows this year, but the
population seems smaller than last
year. There aren't as many nests
as last year. The tulips have grown
up to the sides of the bridge, but have
not yet stopped the birds from getting
under the bridge.
