Central Park, Manhattan, N.Y. City - Monday, June 1st -
Likely the most unusual sighting of all birds seen in Manhattan on the day was a hybrid warbler, known to occur but not found and identified as such all that often, which results from a cross of Mourning Warbler with Common Yellowthroat. This individual was seen in the same area of Central Park on Sunday, May 31 as well, but was not yet fully understood to be this uncommon hybrid. Thanks to D.J. Ringer for alerting more birders to this individual warbler, by Monday, 6-1. We have records of this hybrid cross showing up in N.Y. City from at least the past several decades, but in years-past, it was often a more mysterious pairing and could take consultation over a long period with new world warbler experts to research the occurrence and possible status of such hybrids. With so many more observers and so many tools today in the kit, for recording and spreading the word in recent-modern times, such hybrids may be more widely noticed, and perhaps better understood.
Of other warbler species in Central Park on June 1st, multiple Mourning Warblers were present, all of the reliable reports coming from north of the southern fourth of the park on this day. At least 16 species of warbler were still being seen over the park in entirety and as seen collectively by many observers and photographers on the day. At least 80 species of wild, free-flying birds were noted for June 1st at or over Central Park. Of all of those many birds, none required the euphemism of -early- when found by reliable observers and reporters.
