Pest cos try to say birds of prey are booming as though that's proof anticoagulants are harmless. But here's the truth.
HAVE YOU EVER HEARD THIS BS LINE BEFORE?:
"There are more raptors than there have ever been"?
I sure have--almost always from pest cos and their lobbyists and allies. So rat poisons, or SGARs--can't really be hurting them, right?
First, let's start with a simple truth: NO. There are not more birds of prey "than ever before."
The actual basis of comparison is last century--WHEN WE NEARLY WIPED OUT THEM ALL OUT.
Of course, compared to then, we're doing better. That's a pretty low bar to compare raptors to, is it not?
Do we all know how many/most birds of prey were nearly wiped out last century and what the main culprits were? Here's the first one:
HUNTING.
That's right: birds of prey like hawks, owls, and even eagles were hunted for sport and recreation because they were not valued and were thought of as vermin. Many birds were also hunted to near-extinction for the fashion industry--to supply feathers for women's hats, FFS.
Again, this rampage on raptors even targeted our so-called beloved bald eagles, who fisher folk considered competition for fisheries and farmers viewed as agricultural pests. There were bounties put on them as well as hawks--they were killed in horrible ways by THE THOUSANDS.
Even the National Audubon Society--known back then as the National Association of Audubon Societies--referred to hawks and other birds of prey "as vermin." Get this: they even allowed sports hunting of these species on some of their conservation lands--even games and contests. It took an outsider--A WOMAN named Rosalie Edge--to fight them hard on that in order to get that s**t to stop.
Then came the second blow in this 1:2 strike: PESTICIDES.
In fact, the same year the Bald & Golden Eagle Protection was passed, DDT was patented as an insecticide. So the eagles and hawks and herons--whose populations were already struggling to rebound from en masse hunting and poaching, then were dying off from pesticide exposures to the point of near-extirpation.
What had to happen to recover them?
WE HAD TO PASS LAWS AND BAN MANY PESTICIDES AND CERTAIN HUNTING PRACTICES.
Hunting of most kinds of birds of prey only became illegal in 1972. THAT SAME YEAR, DDT WAS FEDERALLY BANNED.
Many of the species like Bald Eagle and Peregrine Falcon were federally listed as endangered and afforded special protections and a recovery plan under the newly established ENDANGERED SPECIES ACT. Their recovery plans included incubating THOUSANDS of eggs, feeding chicks with puppets and having humans take care of fledglings. I mean, it was AN EFFORT. Not just "presto chango!" and these birds are back to baseline. It took LOTS OF MONEY AND TIME. And even with that investment, it still took a whole HALF-CENTURY for them to have healthier numbers. But let's be clear--STILL NOWHERE NEAR the historical numbers they had before all the bad s**t started happening in the late 1800s/early 1900s.
Let's also talk about the here and now re: raptor populations. Are they really doing as well as pest cos claim them to be?
Well, here in Massachusetts we have quite a few birds of prey on our state endangered species list besides just Bald Eagles (which yes, are still listed and vulnerable): Peregrine Falcons, Barn Owls, Long-eared owls, Short-eared Owls, and Northern Harriers. These last four species are on a serious decline in the region.
And while not MESA listed (for some reason I don't quite understand), Snowy Owls are IUCN Red listed as Vulnerable to extinction (the category right before endangered). Snowy owls are also a species of Greatest Conservation Need in Massachusetts, as are American Kestrels. American Kestrels are on the decline across the US and are doing particularly poorly in Massachusetts and anticoagulant rodenticides seem to be a contributing factor. Sharp-shinned hawks are also on a major decline.
Even Red-tailed hawks--our most prominent raptor in Massachusetts--are having challenges. One study from Tufts found 100% exposure rate to SGARs. A study by Keshia De Freece Lawrence—a researcher and Indigenous Education Specialist at Harvard Forest and member of the Ramapough Lenape tribe--found alarming localized losses of RTHs. When adult hawks die from SGARs toxicosis or vehicle strikes, it degrades population health over time.
Does that sound like raptors are doing "the best they ever have"? It doesn't to me.
