As every birder in New Jersey and the northeast knows, spring migration in 2013 is becoming one for the books and not a very positive book at that. Check the various bird migration forecasting web sites and radars and the picture remains the same: the northeast is in an easterly cycle of weather. Breeding birds are slowly trickling in but the northern migrants are keeping west of the northeast. It is eerie.
It is May 3. Look at the screen shot of the eBird Range Map depicting all of the reports for Swainson’s Thrush as of May 3, 2013. The mid-west is well represented. This species should be coming into our region now. As of today, there is not one report from New Jersey, New York and all of New England. None.

The long-range forecast on various Internet weather sites is for a continuation of this cycle until next weekend, with a southern flow of air possible in time for the World Series of Birding on May 11.
