However, in this post, I’d like to lay out the basic numbers as we pretend to know them about overall bird mortality, human related causes of mortality, and somewhere in there I’ll note that the number of birds that are killed by windmills is so small that it says “zero” on my pie chart.

The tiercels (young Peregrines) must deal with Golden Eagles, Ravens, adult Peregrines, and foxes; they must also learn to navigate the skies and make their own kills, luckily these skills appear to be innately learned. Coyotes took carrion from young Condors and then killed the weakest ones. It’s not easy.

And so, when Salvador Ramirez left, there were feral goats on the island of San Clemente, the southernmost of the Channel Islands off the coast of California. And so, a man named Salvador Ramirez brought a small herd of goats from Santa Catalina Island where he was to San Clemente Island where he went to live.

One odd flock of Feral Pigeons above an arable field under deep snow – nothing for them to eat there, but I didn’t give them the attention they deserve and only a few hours later realised that they actually were Stock Doves. And I didn’t pay enough attention because one very dark eagle flew by at the same time, an adult Greater Spotted Eagle.

They range from the successful eradication of feral cats from Marion Island (hear that, Corey?) The leopards place their kill in a tree, protecting it from poaching by other predators. So, the best way to find a leopard is to find the kill. Verreaux’s Eagle-Owls are amongst the heaviest and longest owls in the world.

Its numbers are declining rapidly due to feral cats and this duck is currently listed as vulnerable. These predatory thrushes have been known to prey on albatross and Spectacled Petrel eggs, the young of Great Shearwaters and have even been known to remove storm-petrel species from their burrows and kill them.
