Interesting as always. I see that Yellow warblers are down, but at least ar=
ound here there seem to be more than ever on territory. That suggests to me=
that migration for this species has already peaked. I wonder if there is a=
good way of comparing your nocturnal call numbers with ebird numbers from =
say 2 weeks ago, or are the numbers too small?
