[PlanetWaves99@xxxxxxx]

A bunch of people contacted me off list with some ideas as to why Ravens were 
seen in eastern northern VA.  Here's a brief synopsis:
1) Ravens have been seen closer to this location in the past few years 
including a nest site somewhere near Manassas.  So maybe they're expanding 
their 
range.  (if not their breeding range, then possibly their foraging range).

2)  Ravens have been seen at the Occoquan NWR before.

3)  They could be young birds who've been kicked out of their parent's 
territory and are looking for territory of their own.

4) "Nature abhors a vacuum"     The Department of Agriculture has, for three 
years in a row, poisoned Corvids in Fairfax County.  There is some speculation 
that these birds (the Ravens) are migrating into the County from outside the 
area to take advantage of the food supply and lack of competition.

Thanks to everyone who answered me on this.
