The radar imagery from NWS Binghamton continues to show what looks to be
bird migration well after sunrise. As of this writing it is 1000 am and we
are still picking up biological targets. Since the lower atmosphere's
thermals haven't begun, it is likely these targets are not insects. Could

I got a call early this afternoon from Reuben Stoltzfus. He saw a couple of
Ruddy Turnstones at Benning on the Wildlife Drive. More intriguing is that he
saw several large Calidris type sandpipers (Ruff? Knot?) at Knox-Marsellus
which he was unable to ID due to severe mid-day heat shimmer. The
Looking at the loop from last night, the reflectivities just about totally
petered out at 6 AM, but then picked up again. That would seem to favor
diurnal migration rather than a continuation of that from overnight.

It would be great to know if diurnal migration of aerial insectivores can be
reliably tracked – not just at the roosts.
I had quite a few Bobolinks over the house mid-morning today (flight calls) –
could also be making up part of the diurnal movement.

Yes I did a long loop and noticed that too. The heights of the echoes are
roughly between 1000 and 4000 feet above ground level. Swallows, icterids,
and what else?

If you look at the national radar loop there is massive diurnal migration
going on from the central and southern Plains to the deep south. It is
impressive. Echoes are especially heavy in the central Plains and mid
Mississippi Valley. see:
