[obol] It's over?

[Don Moore & Pam Buesing]

Yesterday was another big day for migrant movement here in  
Hillsboro.    At almost any time there were multiple species of them  
bathing in my pond.   Today................  NONE.    I went for a  
walk around my neighborhood, and did find two pair of WESTERN  
TANAGERS,  but other than that, it appears that they have all moved  
on.   I will be curious to find out if some of the people that have  
been reporting no or few migrants, will start reporting them now.     
Does anyone know what triggers such a dramatic change?  Are others  
noticing the same thing?
