This spring I am participating in an informal competition with a number of AMNH people for the most species of birds seen in Central Park in April and May. So far it has changed my normal spring birding routine. Among other things it meant going into Central Park on a Sunday yesterday - something I almost never do. It meant spending several minutes working to get a look at a singing Northern Mockingbird high in a tree north of the Reservoir. Heard only birds are worth half a point instead of a full point for seen birds. It meant sitting on a bench by the Evodia Field feeders in the Ramble in the afternoon waiting for a Red-breasted Nuthatch to appear. Despite the fact I had seen probably the same nuthatch there a month ago, in March. My reward for watching for the nuthatch was spotting the White-winged Dove feeding on the ground below the feeders - apparently a first record for New York County. The White-winged Dove is my 350th species for the five boroughs of NYC.
BTW, the Red-breasted Nuthatch did show up a short time later.
