Re: [cayugabirds-l] [nysbirds-l] Diurnal Migration on This Morning's Radar

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.

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.

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.

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 this be shorebird 
migration continuing past sunrise? Or maybe songbirds just continuing from the 
night? I  wish I didn't have to work today...

2019-08-14 Thread David Nicosia 
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?
