Protocol:
Traveling
Party Size:
1
Duration:
5 hour(s)
Distance:
5.0 mile(s)
Observers:
valerie heemstra
Comments:
84-99 degrees, sunny (although storm gathered and it poured shortly after I left); green-headed flies and mosquitoes still out, but not as bad as on 6/22/18 when I was last here. This time I climbed observation towers at both Raymond and Bear Swamp Pools. Huge numbers of birds, probably 2000, mostly semipalmated sandpipers at Raymond Pool. Birds took off when a prop engine plane and a peregrine falcon both flew over coincidentally at the same time (see photos). Low tide when I arrived.

3
large shorebird sp.

One light colored bird, possibly female, standing near 2 or 3 dark birds, possibly male. These birds are quite a bit larger than the Dowitchers. They did not behave like Dowitchers, that were constantly feeding, but stood quietly with heads erect or they preened. They were very distant and these photos were taken with 200x magnification.
