An interesting photograph. Large corvids such as crows and ravens  
often cooperate to steal food from predators like wolves, bears, etc.  
They also seem to relish "teasing" the animals. When I was growing up  
in New Brunswick we repeatedly had ravens that would "tease" our  
samoyed dogs by flying just out of reach above them, or would peck at  
their tails to distract them from chewing on a bone, which they would  
then attempt to steal. They would taken (apparently) brazen risks in  
closely approaching a dog, but were never caught by one.

I suspect this is what's going on here. Except perhaps for ticks and  
fleas there wouldn't be parasitic insects on coyotes at this time of  
year. Crows don't engage in this sort of behavior and I can't imagine  
a coyote sitting still for it, let alone it being worthwhile for crows  
to attempt, given the risks of being killed.

Cheers!

Chris
