My lemon tree has those hidden thorny branches that really hurt when I get stuck by them.Cooper's hawks are common in our community. The Spring fledglings come around watching but w/ no flight space in our yard & brambly thorny Citrus & Pomegranate trees in the yard the hawks can't reasonably fly into or out of those particular trees. Lemon, Grapefruit, & Pomegranate trees look innocent but are densely leafed & have numerous nasty sharp thorns down every branch & budding twig ~ not conducive for perching or flying thru ~ a large bird like a Cooper's has never entered or perched on these trees in our small yard. However the hawks love the less dense leafed trees like Eucalyptus, Maple, or Magnolia trees in other yards or along highway landscapes.
When harvesting fruit or pruning our thorny trees they have torn up our hands & arms even w/thick long leather gloves. The base of all these trees are encircled with rabbit fencing to keep the hens from getting close to the trees yet they will hide behind the shady trees against the block wall apparently feeling safe to do so.

The only time we've seen a Cooper's hawk on the ground is on the street clutching a sparrow in one claw while tearing off pieces w/ its beak only after catching the sparrow in mid-flight first.
