This past weekend I was really worried. There were no birds at the feeders. Usually goldfinch, chickadees and all those other winter bird feeder birds are swarming to the sunflower seeds and suet. Instead, nothing.
It finally occurred to me to look around. High up, at the top of a giant white pine, were two turkey vultures. These eagle-sized birds looked ominous, like birds of prey waiting to swoop down and eat something. I could see why the regulars were in hiding.
However, unlike other birds of prey, these turkey vultures aren’t a threat to my bird feeder birds.
I don’t know what they were doing up there, perhaps enjoying the sun, but turkey vultures are true scavengers. They feed on carrion – not goldfinch, chickadees and other small birds. They did not have designs on my birdfeeders.
Turkey Vultures almost never attack living prey
Here’s what the Cornell Lab of Ornithology has to say about their feeding preferences: “Turkey Vultures eat carrion, which they find largely by their excellent sense of smell. Mostly, they eat mammals but are not above snacking on reptiles, other birds, amphibians, fish, and even invertebrates. They prefer freshly dead animals, but often have to wait for their meal to soften in order to pierce the skin. They are deft foragers, targeting the softest bits first and are even known to leave aside the scent glands of dead skunks. Thankfully for them, vultures appear to have excellent immune systems, happily feasting on carcasses without contracting botulism, anthrax, cholera, or salmonella. Unlike their Black Vulture relatives, Turkey Vultures almost never attack living prey.” In fact, turkey vultures are the only scavengers around here (unlike bald eagles, for example) who can’t kill their prey. Their feet are more chicken-like than hawk or eagle-like, useless for tearing into prey. Their beaks are the powerful part and can tear through even the toughest cow hide. They feed by thrusting their heads into their prey, a good reason for their bald, turkey-like heads.
Turkey vultures are most closely related to storks
The word raptor refers to a broad group of birds of prey – eagles, falcons, hawks and, until recently, vultures. Vultures appear to be very raptor-like. One of the shared traits of raptors is their ability to rip into prey with their powerful talons. Vultures don’t do this, they use their beaks. DNA evidence places them as more closely related to storks than to other raptors. After seeing these turkey vultures, I started looking at my chickens in a different light. Looks-wise, my chickens seem very vulture-esque. They aren’t related –beware of basing relatedness on looks!
It worries me to see turkey vultures in winter. They aren’t supposed to be here. When I entered my sighting into eBird.com (an online birdwatching database), I had to add additional comments because they are unusual this time of year. In fact, turkey vultures are relatively, geologically speaking, new to New England even in the summer. I have a 1987 bird guide in which their range doesn’t extend north of Massachusetts, but, a number of “southern” species like red-bellied woodpeckers, tufted titmice, cardinals, mockingbirds and turkey vultures have been pushing their ranges north since the last Ice Age.
New England is part of the ‘normal’ turkey vulture range in the summer, but recently, with our warmer winters (and perhaps increasing deer population) turkey vultures are lingering into the winter. These two looked healthy. With their bright red bald heads, glossy black wings and shiny white beaks they are interesting harbingers of climate change to come.
For past columns go to my archives–I update this as much as I can-I literally have hundreds out there–just need to get them into one place (here)
