20 September 2011 'Triple Doppler' NEXRAD

Here's the second of two views of the early evening -- just after sunset -- lift-off of biota combing Buffalo, Tug Hill, and Binghamton radar stations (clockwise, from left side). In addition to this representing a huge night migration (note green centers to the blooms), this evening's imagery shows an unusual lift-off of birds originating N or Kingston. Listeners (to night flight calls overhead) reported several more northerly species calling: Black-throated Blue & Green Warblers, plus Lincoln Sparrows, for example. This S Ontario effect will be interesting to watch for as Yellow-rumped Warblers herd southward within the next weeks. Another, more local view featuring just the Tug Hill imagery, can be viewed here: http://www.youtube.com/watch?v=fk9xaBUFe1Y [loops 3x]
