hmmm -- sounds like we need to be somewhat more alert
we have bald eagles in the big fir trees that edge our neighborhood to the north, along the power canal, but they seem to prefer to hunt over the livestock quarantine facility just north of that, which includes some marshy areas where redwing blackbirds sing ... or over the river which is another quarter mile or so, north, at this point
redtail hawks too, though I would expect them to go after the rabbits, rodents, possums, and squirrels down the hill too
haven't seen any owls, just lots of bats (we have a bat house attached to the hangar out back)
I suspect predators tend to avoid us because of loud barking by our dogs and a lot of "solid evidence" all over the yard ... cat spray too ...
(the cats pretty well clear out the mice, rats, moles, and voles that dare to come on the property)
deer go after the roses in my neighbor-to-the-west's yard (not so much now that they put up a seven foot chain link fence with barbed wire atop), and the fallen apples and pears in my-neighbor-to-the-east's, though I've been picking up a lot of those and giving them to the chickens, who make short work of them .. neither of them has a dog, but now the next-further neighbor to the east has acquired a very bark-y dog
I suspect my third neighbor to the west will be easier pickings; his hens free range unattended all day (though they have lots of large construction equipment to hide under); ours are either in the tarp-covered run, in the chicken tractor, or we are sitting right beside them supervising when they free range, for half an hour or so
if I can train Roxy to be a livestock guard dog, that will be even better -- but while she is pretty much mature (about 2-1/2), I suspect it will take a LOT of training ... and DS may not take the time to keep up with that (technically Roxy will be HIS dog, we're just temporarily minding her)
no bears that we know of, no cougars; we do have bobcats but know about this only from the occasional halfbreed kitten; a couple of neighbors have loaded .223s to take care of the occasional coyote
