I believe that... I was out at my empty pigeon coop this morning... remembering how it was. I could not let them out without the hawks swooping in within minutes. It seemed there was no end of them. I got tired of fighting them. I typically leave the chickens in this time and later in the year because the hawks are so desperate. But even looking at the song birds. They are getting scarcer and scarcer... by February they will be very scarce. The game warden says rabbits are low... who eats rabbits? Coyotes and hawks. The coyotes are a problem like the hawks. But the squirrels seem thick enough. I don't know. In the past, I have handled hawks that were skin and bones. There needs to be a natural predator that eats them. Maybe an eagle or a huge eagle owl which lives in Europe.By me the game warden said there are too many hawks and something needs to be done.
