This Pied-billed Grebe is possibly the same bird that appeared on the reservoir for the 2006/2007 winter season the day I was out birding with Omar Morales on 30-Sep-2006. It arrived in juvenile plumage and has recently begun to acquire its adult plumage as noted by Jack Meyer in a recent post to eBirds NYC.
Here's a link to a photo by Cal Vornberger taken of the juvenile on the reservoir on 11-Dec-2006.
