[MDOsprey] Nighthawk migration: another take

Hi, 

With the recent / current discussion on MDOsprey list about Common
Nighthawk migration, I thought the following would be of interest.  

This morning on the PABIRDS list there was a report of a Nighthawk watch
from Allegheny County, which is adjacent to/encompasses Pittsburgh.  If
anybody not on that list wants me to email the message, let me know
privately and I will email it to them.  I will say that the peak days for
this count were as follows: 

Aug. 22 - Aug. 27.

On those days (one of which received no coverage!) 1443 out of the total of
1775 nighthawks passed.  The nighthawkwatch went from August 5 to September
6.  

By the way, the rate of yesterday's Monarch migration past my office window
in downtown Bethesda decreased after lunch, to 1 every 2 to 5 minutes.  

Best, 

Rob|
