[birding] RE: raptor question from Linda Fink

[Linda Fink]

Thanks, Don. Your juvenile calls do sound like the calls both these 
hawks were making. Only the one by the house broke into the regular 
Cooper's scolds that I normally hear only near a nest site. (They do 
nest here.)

I'm still hearing Great Horned Owl juveniles or at least juvenile 
sounds, so maybe young hawks continue to beg into fall. Hopefully 
sometime I'll see the hawk making the sound and know if it's a juvenile 
or not. Maybe they continue to make those begging sounds for the same 
length of time they have their juvenile plumage. Anyone know?

It's interesting how similar the juvenile Cooper's begging sound is to 
the Great Horned Owl begging sound. At least, to my ears.
