There's no way to tell what's going to be seen. Sometimes I have a plan,... start at Riverside Drive to check on the hawks, then get to Central Park. In this two hour stretch I saw that the hawks were fine, stopped to greet my favorite mockingbird, got to Central Park and saw the bathers and nest-building mud-faced robin, a very sweet field sparrow (don't see them often), the yellow rump warbler, the towhee and the B/W warbler, a very nice assortment for two hours. I heard an oriole and another warbler, but couldn't find them in the tree tops. The serious birders would not be impressed, but I don't find any bird to be ordinary. I'm glad we share the same space.
