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. So keep that in mind.
And for rodents and reptiles as well. This is approximated by the size of the animal, but really, this has to be adjusted for depending on modality of killing. And for thousands of years the lizards, rodents, and birds of North America adapted to Fishers, Badgers, Wolverines, Ermines, etc. Let me tell you this: They are.
For instance, assume (and I will NOT stand by this number, it is just one I’ve heard here and there) that kitty cats in America kill 50,000,000 birds a year. Hardly any Sandhill Cranes are killed by domestic (including ferrel domestic) cats. In fact, there are certainly a few cats killed by hawks every year. Raptors either.
Consider this: ninety percent of birds treated at wildlife centers are admitted as a result of human interactions that have nothing to do with “nature.” Our world has changed, and humans have created that change. Wildlife no longer exists in the same way it did before humans came on the scene. The difference seems obvious.
If there are human fishing activities then all the better – Marabous will gather in numbers around fishermen’s docks and fish markets, in fact anywhere where fish are cleaned and scraps disposed of, allowing these intelligent birds to obtain a free meal. They are also attracted by fires and can gather in thousands.
I should add that the Big Owls taking over NYC social and even hard print media, dominating conversations with my nonbirder friends and family, are not the only owls in the five boroughs, but like a musical, the closer you are to Broadway, the closer you are to fame and fortune (and maybe even a higher quality rodent for dinner, who knows?).
They are harmless to humans and their horns are used for wrestling other males for mating rights. This sleek, stunningly patterned cat was a formidable hunting subject, and in its cunning sometimes ended up hunting and killing the hunter. to the far reaches of freezing Siberia.
The Calgary Zoo is again under scrutiny as details emerged Friday about how a capybara, a species of giant South American rodent, died after becoming caught in a hydraulic door last weekend as it was being moved from one area to another. In November 2008, a virus killed a 15-month-old Asian elephant calf named Malti.
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.
For Engber, who dispassionately describes procedures most of the time, the "advances" in the medical care of humans are all well worth what he and other vivisectionists do to dogs and other sentient nonhumans. By the end of my time as researcher, I was performing behavioral experiments on humans. It "guarantees humane treatment?"
Dogs are able to detect diseases such as cancer and diabetes and warn humans of impending heart attacks and strokes. In many ways, human emotions are the gifts of our animal ancestors. I also watched a red fox bury her mate after a cougar had killed him. Grief in magpies and red foxes: Saying goodbye to a friend.
But in the case of Harris Hawks , this mentality jumps the species barrier and they form a strong bond with their human partners, readily accepting their non-avian hunting companions as members of their pack. I have never been one to advocate the needless killing of animals for whatever purpose. League Against Cruel Sports.
I’ve observed nesting owls, fledgling owlets, owls eating small rodents, owls coughing up their pellets, a Great Horned Owl silently flying over me, a Great Gray Owl sitting regally still on a post as a boy walks up to him, a pair of Barking Owls duetting in early evening hours outside my northern Australian hut as I brushed my teeth.
