Big migration over the Eastern Flyway


Wow. The radars were working overtime last night! Lots of birds were migrating up and down the east coast, and many seemed to be flying lower than usual due to the unfavorable winds at higher altitudes. My interpretation is based on the messiness of the radar images and the strong echoes (green) around the origin of the radar. Since birds flying lower will be picked up closer to the radar’s origin (and not picked up farther from it), the “broken” look of the radar at greater distances suggests that less birds are flying higher, while the concentration near the origin suggests that more birds are flying lower. Wow- it’s 6:01- okay I need to get the radar posted! Best bets are migrant traps, with my pick being Garret Mountain since birds had a more S–>N directions early this morning. Please post your observations when you get a chance.

  1. On the marsh edge at Reed’s Beach from 6:30-7:15am:

    1 Eastern Kingbird (FOY)
    1 Common Yellowthroat (FOY)
    2 House Wrens (FOY)
    10-12 Chipping Sparrows (usual max = 2)
    25+ White-thraoted Sparrows (up from ~12 yesterday)
    4 Field Sparrows (uncommon spring migrant in the yard)
    1 Golden-crowned Kinglet (first since Feb)
    2 Yellow-rumped Warblers (first since March)

    Other notables on the move included 3 Kestrels, 1 Common Loon, 1 Little Blue Heron and 75 Black Scoters high over the beachfront.

  2. Hello all,

    There was a moderate number of birds today at Garret Mtn. The most conspicuous migrants were YRWA (42), PAWA (37), PIWA (11), RCKI (34), HETH (25) and NOFL (32). Also seen in small #’s: GCKI, BRCR, YBSA and BHVI (3). Broad-winged Hawks were evident in the park this morning roosting and slowly getting up with the warm sun. Three boisterous ravens were over the park all morning croaking, gurgling and generally carrying on. They seemed to enjoy soaring with the departing broad-wings.

    I hope everyone enjoys Earth Day.

  3. Unfortunately my dog had an incident with some wildlife this morning (she’s fine) which caused me not to be able to finish my walk, but several FOS birds were found today. These were:

    Yellow-bellied Sapsucker
    Blue-headed Vireo
    Prairie Warbler

    Notable also were the number of Ruby-crowned Kinglets- they were everywhere and outnumbered Golden-crowned by a landslide. I’m going to take another trip around the property this evening and see if I can turn up anything else.

  4. Sandy Hook today did not experience any large migrant flight, though kinglets seemed abundant and I saw my FOY blue-gray gnatcatchers. DC Cormorants were all over the bay, and there was a steady flight of singleton swallows along the ocean beach in the morning.

    The hooded warbler continued at the hawkwatch.

  5. This is by no means a comprehensive list, as I was only able to bird for 40 minutes this morning and a little this evening, but some cool birds were definitely around.
