["michael sylva" <mtnsylva@xxxxxxx>]

We'd been seeing about 150 double-crested cormorants at dusk in a stand of 
eastern cottonwoods east of the RR crossing into the Rankin WMA in Cocke 
county.  Yesterday, at the usual time, there were no cormorants, but one bald 
eagle in a snag at the center of the stand.  Another immature eagle was perched 
on riverbank cottonwood, a couple of hundred feet away.  There were also 2 
ospreys perched in the area, as there had been when the cormorants roosted 
there. I don't think the eagles are any more of a threat than the ospreys are 
to the cormorants, although I've read that eagles will rob fish from ospreys.  
>> Different interspecies tolerances for different birds; we've also seen an 
eagle clear out an islet occupied by a flock of white ibises at Ding Darling 
Refuge in Florida.  Maybe an eagle dummy would be more effective as a bird 
deterrent than those synthetic great horned owls.  >> BTW, we heard two live 
GHOs after sunset at Rankin last night.
