Was there shortly after 6pm. Not much notable around except for two pairs of 
Fish Crows. They were flying around and visible from the exposed ledge that is 
best reached by taking the first trail on the right after entering the park and 
following the trail until you see a turquoise piece of PVC pipe. A little used trail 
breaks off at the pipe and heads slightly uphill to an exposed ledge. The birds 
were sitting in two separate pines about a hundred feet apart, calling 
incessantly. Occasionally they would fly around, continuing to call; maybe 
some kind of mating or territorial thing? The call was obvious, but in addition 
at one point a couple of the Fish Crows were in flight circling around while 
American Crows were flying by and the subtle overall size difference and 
smaller head were apparent. Eventually they took off and headed east-
northeast (more dumpsters in that direction).
