Re: [cayugabirds-l] Crows chasing ravens

2015-04-12 Thread Geo Kloppel
Hi Ben,

I just saw the same thing a moment ago, except the Raven was flying _toward_ 
the L-P preserve (that is, leaving the nest area on a foraging mission), and 
very tightly harassed by a Crow, all the way down to the WD Fire Station area. 
Might even have been a member of the Crow family that's currently nesting in my 
yard, since the Ravens are passing back and forth right over the Crows' 
territory.

 Hello,
 
 I went for a nice walk this morning at Lindsay-Parsons Biodiversity Preserve. 
 Phoebes are back, Great Blue Herons are standing on nests near the fire 
 station (looked like seven occupied nests), fox sparrows and golden-crowned 
 kinglets were around, and a smattering of migrants passed overhead (common 
 loon, rough-legged hawk, and many turkey vultures).
 
 One interesting observation I wanted to share: I was watching a raven fly 
 across the valley when a bird came out of nowhere to chase and harass the 
 raven. It was a crow, and the crow followed the raven until I lost sight of 
 the two corvids. I've seen small groups of crows harass solitary ravens many 
 times, but don't think I've previously seen a single crow harass a single 
 raven with such vigor.
 
 Best,
 
 Ben

[cayugabirds-l] Crows chasing ravens
