Saturday Field Notes, Apr. 20, 2013

Morris Lakes

Last night’s storm and passing front did not create any significant events in the mocosocoBirds region. Boonton Reservoir had a Red-throated Loon (Simon Lane) and 7 Common Loons besides the typical species. 70 Double-crested Cormorants were counted, but many more are in the area.

Mt. Hope Lake continues to have Ruddy Ducks in triple digits, 150 today. 1 Horned Grebe and 4 Pied-billed Grebes joined the two resident Bald Eagles and 2 Bufflehead. A Trumpeter Swan kept its distance from the 62 Mute Swans. Eventually, it flew out of view behind a patch of Phragmites. One of the Bernadsville Trumpeters?

Raritan Flyway

The Raritan Flyway was active today on the Delaware and Raritan Canal Towpath in Franklin Township. A flight of at least 100 Chimney Swifts, 40 Northern Rough-winged Swallows, 150 Tree Swallows, the mocosocoBirds region’s first Bank Swallow of 2013, 15 Barn Swallows, 1 Northern Parula (also a 2013 first for mocosoco) 9 Palm Warblers, 5 Pine Warblers and 230 Yellow-rumped Warblers were the highlight of the morning.

Other notes

Purple Finches continue to be reported from feeders (Alan Boyd, Jamie Glydon).

From Leslie Webster:
No Yellow Warblers yet at Loantaka Brook Reservation yesterday, but it’s good to know they are on their way! There were numbers of Yellow-rumped Warblers, a couple of Pine Warblers, and some Palm Warblers. Three Eastern Towhees were counted, one singing and the others calling. A Louisiana Waterthrush was singing–a new species for me in LBR.

A Pine Siskin continues to appear at a feeder in Basking Ridge (Jennifer Books).
