Central Park - Apr 2 - Red-necked Grebe continues

This morning was the first of my spring bird walks in Central Park for the American Museum of Natural History.  I lead them every Wednesday and Thursday mornings in April and May. Normally, we bird the Ramble primarily, but this morning we only skirted the Ramble in order to go north to the Reservoir to look for the Red-necked Grebe that has been present for about three weeks. We were successful! Following is the entire trip list of 40 species.
