In a previous blog, you read that VINS received a dead oceanic bird the day after Tropical Storm Irene swept through Vermont. The Wildlife Services staff at VINS believed it to be a Wilson’s storm-petrel, but upon further examination, the Vermont Center for Ecostudies determined that it was actually a band-rumped storm-petrel, the first of its kind ever recorded in the New England area!
The photo on the left is a Wilson’s storm-petrel and the photo on the right is a band-rumped storm-petrel, for comparison. 
so haed to tell the difference
