Pity those who do not bird or study nature this time of year. April is flipping the calendar page to May and the climax of spring migration is close at hand. It is impossible to venture into the woods and fields this past week and not find new bird, plant and insect species for the year.

Although the radar has shown little migration in north New Jersey the past few days, birds are everywhere in the proper habitat. American Redstarts have invaded the Snake Hill Road-Lake Denmark area as witnessed this morning. Yellow-throated Vireos are moving into their usual spots. Four not-so-Solitary Sandpipers were seen on one sliver of mudbar at Loantaka Brook Reservation yesterday. Cliff Swallows have returned again to Boonton Reservoir. Every day brings new migrants and nesters into the area.

All of New Jersey’s nesting Vireo species are in the mocosocoBirds area. Warbler numbers are growing. Empidonax flycatchers are on their way with the season’s first Least Flycatcher visiting the Great Swamp NWR this morning (Simon Lane).


This morning, a Fish Crow called diagnostically and frantically while perched on top of a high voltage tower at Lake Denmark. Eventually, the local Common Raven came into the area at which time the Fish Crow commenced to harass the Raven for the next few minutes creating the silhouette image below. Both corvids eventually flew off.
