[Douglbirds] Dave Rapley's magpies

[David E. Rapley]

Interesting.  We have several black "crow like" birds but larger. Could they
be Ravens?

We think that a lot of the corvids got severely hit by West Nile virus.
Magpies and crows had the hardest hits. The crows have rebounded and we
certainly see plenty of magpies around here. 

 

These roosting congregations occur seasonally, I think. With the West Nile
devastation maybe the recovered birds have developed different habits. 

 

One of the best sources to pick out population trends are the various
Christmas bird counts. One of these days I'll do a pass-through to see what
they show.
