Group feeding in flooded north of Bear Lake.
There were a large number (10+) of these raptors sitting in a field (!) in fairly close proximity, which I have never seen before, but I did not get a good look at most of them and am not very good with raptors.
Either Northern Spreadwing (Lestes disjunctus) or Lyre-tipped Spreadwing (Lestes unguiculatus). Both are known from the area, but of course I didn't get a photo of the back of the head or the ovipositor.
Can anyone tell which one this is?
