In NJ the black vultures are relatively new - I first saw them about five years ago. They attack newborn calves, lambs, kids. I wonder if they get fawns but the fawns are darn nigh invisible. I’ve been within six feet of one before seeing it.
USDA report on the vultures here.

Sounds like the biggest problem is roosting - some people in the next town had about 50 on their roof every evening - can you imagine the damage from the guano and the reek of it?
A few, not many, have picked my pine trees, to judge from the white streaks on the rhodondrons. I try to discourage them when I see them sweeping in low - they’ll make twenty circles before landing. I’m a lousy rock thrower, so will invest in a beebee gun or slingshot if the numbers increase.
Hey! Where's your entrepreneurial spirit!
The Spanish made a fortune shipping guano from Central America back to Spain!
