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.

It is impressive. Echoes are especially heavy in the central Plains and mid Mississippi Valley. see: https://radar.weather.gov/ridge/Conus/full_lite_loop.php On Wed, Aug 14, 2019 at 10:24 AM Peter Reisfeld <drpi...@yahoo.com<mailto:drpi...@yahoo.com>> wrote: 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.

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... -- NYSbirds-L List Info: Welcome and Basics<http://www.northeastbirding.com/NYSbirdsWELCOME.htm> Rules and Information<http://www.northeastbirding.com/NYSbirdsRULES.htm> Subscribe, Configuration and Leave<http://www.northeastbirding.com/NYSbirdsSubscribeConfigurationLeave.htm> Archives: The Mail Archive<http://email@example.com/maillist.html> Surfbirds<http://www.surfbirds.com/birdingmail/Group/NYSBirds-L> ABA<http://birding.aba.org/maillist/NY01> Please submit your observations to eBird<http://ebird.org/content/ebird/>! -- -- Cayugabirds-L List Info: Welcome and Basics<http://www.northeastbirding.com/CayugabirdsWELCOME> Rules and Information<http://www.northeastbirding.com/CayugabirdsRULES> Subscribe, Configuration and Leave<http://www.northeastbirding.com/CayugabirdsSubscribeConfigurationLeave.htm> Archives: The Mail Archive<http://firstname.lastname@example.org/maillist.html> Surfbirds<http://www.surfbirds.com/birdingmail/Group/Cayugabirds> BirdingOnThe.Net<http://birdingonthe.net/mailinglists/CAYU.html> Please submit your observations to eBird<http://ebird.org/content/ebird/>! -- -- Cayugabirds-L List Info: http://www.NortheastBirding.com/CayugabirdsWELCOME http://www.NortheastBirding.com/CayugabirdsRULES http://www.NortheastBirding.com/CayugabirdsSubscribeConfigurationLeave.htm ARCHIVES: 1) http://email@example.com/maillist.html 2) http://www.surfbirds.com/birdingmail/Group/Cayugabirds 3) http://birdingonthe.net/mailinglists/CAYU.html Please submit your observations to eBird: http://ebird.org/content/ebird/ --
