18 October 2013 Migration Report

Ho Hum.  Under superb conditions only a moderate flight across the region.  Still plenty of birds in the pipeline but it looks like they will be trickling in over the next month. With such unseasonably warm and rainless weather perhaps there is no urgency to leave the northern realms.  I’m seeing lots of bugs and even good numbers of dragonflies out in the field. The local unmanaged seasonal wetlands are dry as well.  I’ll keep an eye out for a pulse, but this is a signature of a waning season that is being drawn out.

The high pressure ridge remains stable and the winds will be driven out of the north.  Some temperature differential winds will be driving an easterly component, but mainly during the daylight hours.  Clear skies for a few more days at least.

Over the weekend i’ll be out in the field so you’re on your own to monitor the skies.  I’ll do a recap on Monday.
