This week’s weather, consisting mostly of a damp, chilly, easterly-northeasterly air flow, has slowed the migratory push that observers crave this time of year. Nonetheless, birds are everywhere at this time.

41 Common Loons waited out the rain in Boonton Reservoir today. The above photo is a sampling of the loon gathering. Most were in two large groups with singletons and duos resting and feeding in the reservoir north of the island. All but two were in alternate plumage.

Red-headed Woodpeckers continue with 4 at Glenhurst Meadows reported today (Jeff Ellerbusch) and 10 at Troy Meadows (Roger Johnson).

Rose-breasted Grosbeaks are everywhere this week with many people reporting them at feeders (including this writer) as well as in the field.

Hermit Thrushes have moved on from most of the Morris/Somerset area. Veerys have moved into their preferred habitats. The mocosocoBirds area’s first Swainson’s Thrush was not reported until early this evening at Jockey Hollow.

One phenomena that the wet, low-pressure, dreary weather can create is large congregations of swallows over lakes and ponds. Migrating Bank Swallows were found in several places amidst the Tree/Barn/Northern Rough-winged Swallow flocks this week. Barn Swallows have arrived in full. Chimney Swifts are finally back in Morristown. A visit to Budd Lake on May 4 produced hundreds of swallows including ~50 Purple Martins.
