Lenore Swenson’s walk in the Central Park North End this morning had 57 total species including 9 warblers and 8 sparrows. Overnight migration was very strong after the passage of a cold front yesterday. It was also the coldest morning of the fall so far, with temperature around 41 at the start of the walk.
A Black-billed Cuckoo was briefly heard (but not seen) just off the path exiting the east side of the Great Hill at west Park Drive, latitude 106th Street. This was a new bird for both the season and the year (#152). This species is observed only once or twice per season in the Park.
An Orange-crowned Warbler was seen just south of the Meer. This is another excellent find.
Ruddy Duck, on the Meer, is a new bird for the season, as is Savannah Sparrow, on “Sparrow Slope” of the Great Hill. The group also saw White-crowned Sparrow on the Great Hill.
Other warblers seen were the usual ones: Black-throated Blue, Common Yellowthroat, American Redstart, Black-and-white, and Magnolia.
Overnight migration appears to have brought more Hermit Thrush and Golden-crowned Kinglets, both of which were abundant. The former has just begun to be seen regularly this week.
