- You may have gotten wind,
0:01
the turbines like these are killing all the birds,
0:05
so wind power's bad, but how accurate is that?
0:08
Yes, wind turbine collisions account for somewhere
0:10
between 140,000 to around 680,000 bird deaths each year.
0:15
Mainly small migrating songbirds.
0:16
And that's why the people who plan
0:18
where wind turbines go work to study
0:20
and avoid bird migration roots,
0:21
sometimes even turn off wind turbines
0:23
during peak migration times.
0:25
Okay, that's not nothing
0:26
but those wind turbine numbers pale in comparison
0:28
to how many other bird deaths we are responsible for.
0:31
Around 6 million birds crash into communication towers
0:34
like the ones your phone's talking to you right now.
0:35
These towers are tall.
0:36
They shine lights in the night sky,
0:38
which can disorient songbirds traveling at night.
0:40
And up to 50 million birds get tangled
0:42
in overhead electricity lines each year,
0:44
with about 5 million getting electrocuted by 'em.
0:46
About 72 million birds get poisoned each year
0:49
by things like pesticides we use to protect our crops,
0:52
or lead poisoning from spent ammunition,
0:54
swallowed by scavenger birds feeding on carcasses.
0:56
And more than a billion birds die every year
0:59
from crashing into big glass buildings or household windows
1:02
or other confusing glass things we keep putting everywhere.
1:04
I guess it's clear, you know, what do you expect?
1:06
But you know who the real killers are,?
1:08
Domesticated cats.
1:10
Yes, more than 3 billion birds,
1:12
billion with a b,
1:14
get killed by household kitties or feral cats every year.
1:17
That's almost one feline bird murder
1:19
for every two humans on Earth.
1:21
"Not my cat," I hear you saying.
1:23
And to that I say, "Yes."
1:24
Even your cat.
1:26
Cute, but also deadly murder machines.
1:29
Anything that kills wild birds is not good.
1:30
But it seems like if you want to save the most birds,
1:33
maybe we should be talking about cats instead.
1:35
Don't ask me though, I'm a dog guy.
