Birds on the move

Birds are desperate to migrate! Both the Fort Dix and Dover radar stations were showing nocturnal migration last night despite the less-than-perfect wind conditions (from the north at altitude, but calm at the surface). This is a moderate migration event although new birds clearly made it across the Delaware bay and into South Jersey including the entire bay shore and Cape May. Birds travelled on a due north trajectory spread across the entire state, suggesting that both Garret Mountain and Sandy Hook are worthy destinations as they should have new birds this morning.

Good Birding

  1. Best day so far in Tenafly. Over 2 dozen Palm Warblers, arriving Yellow-Rumps, and continuing Pine Warblers. All in the highest numbers to date.

    New arrival is Blue-Gray Gnatcatchers.

    3 Double-Crested Cormorants flying north, high overhead.

    Tomorrow will be better & I’llhave more time as well.

  2. An hour walk this morning around Belleplain State Forest was nice-had a two Black and White Warblers, male Pine Warblers being very territorial and chasing each other around, several Louisiana Waterthrushes singing, heard a single Palm Warbler, heard several Yellow-rumped Warblers, loads of Yellow Throated Warblers and had a White-eyed Vireo this morning as a new arrival-
    Good Birding!

  3. 2 Yellow-rumped Warblers, 1 Black and White Warbler and 1 White-eyed Vireo during work this morning. That actually is very good! The last two could breed in the area or be moving on, I don’t know. It was south surface winds at 3:10AM. It looks like from your radar that the birds didn’t move too far, started in DE and just headed north straight up the state? I am trying to learn to read this.

  4. At UPenn (Philadelphia, PA), the Biopond had a Ruby-crowned Kinglet this morning. I’ll try to check later in the day as the Biopond usually is better in the early afternoon. The kinglet is only notable in that the Biopond hasn’t had any migrants for three weeks.

  5. Wow! Look at all those great comments! Thanks everyone!
    So after the DVOC talk and checking out the radar last night, I was only able to catch about 3 hours of sleep before getting up to post the radar animations. I tried to go back to bed at 6:00am, but the dawn chorus was way too raucous, so I donned my jacket, gathered my eager companion Tess, and headed out the door to see what was around. I immediately noticed an absolute abundance of Field Sparrows; more than I can ever recall seeing in one day. They were EVERYWHERE.
    I focused on several trees that were getting the first morning light and found a group of Yellow-rumped Warblers and Palm Warblers, all singing. This was the first time I’ve heard Yellow-rumps singing this Spring. Several of them were in almost complete alternate plumage as well. Overall there wasn’t anything new at my place- although there were many MANY birds around.

    Here’s the complete report:

  6. Best day at the Celery Farm in a while. 3 new arrivals: Broad-wined Hawk, 2 Field Sparrows, and Savannah Sparrow–the latter 2 are very uncommon at CF in spring–and I heard both sing–never saw a singing Savannah here before–very cool. First big push of warblers with 15+ Palm and 5+ Rumps–many of them singing and the Rumps in fine plumage. Also a singing RC Kinglet. Spring is finally here to stay!
