From Alan Boyd:
Jonathan, I had my first hummingbird of the year at my feeder this morning.

This can be added to two Ruby-throated Hummingbirds (RTHU) reported in Morris County yesterday in Rockaway Township (Steve Fasciana) and Chatham Township (Simon Lane).

Here is an image of an eBird map of the RTHU range based on reports in April of this year:

And here is a close-up of RTHU in New Jersey and Delmarva region in April 2012:

The slow migration in the northeast continues. Vireos, Black-throated Green Warblers, Northern Waterthrushes, Eastern Kingbirds, Wood Thrushes, Veerys and a few other species are slowly making their way into the Mocosoco region. The huge push of Swallows may have subsided.

Jeff Ellerbusch reports that the Glenhurst Meadows’ Prothonotary Warbler and Vesper Sparrow remain there as of today.

Jamie Glydon reports first-of-the-year arrivals today at Bee Meadow Park in Hanover Township: Baltimore Oriole, Warbling Vireo, American Redstart and Great Crested Flycatcher.

As for favorable migration weather (there sure hasn’t been very much in our area for weeks), look to Woodcreeper for migration forecasts.
