Why Evolution is True is a blog written by Jerry Coyne, centered on evolution and biology but also dealing with diverse topics like politics, culture, and cats.
It’s hard to be sure in the picture, but the multitude of status lights are probably on. If only the Quad Blaster 4 ultrasonic transducers had failed, how would a human be able to tell?
That is great! Love it!!!! LOL
There are no ultrasonic birds in the picture, right?
Very good point.

That was me, twice. Meant to give just one. Sorry.

It’s perhaps better at repelling bats!
Clearly they sent in a deaf bird to unplug it.

No additional comments either.
This is an ex-repeller.
Reminds me of the device my folks purchased from a magazine AD some time back. I think the price was $150 or more and it was advertised as a new way to soften your water without all the cost and bags of salt. Just plug it in, hang it on the water pipe and wrap the wires around the pipe. The only thing soft is your head.
We will tactfully not mention your parents’ heads…
I remember that product! Oh, I so wanted it to work, but my chemistry knowledge couldn’t make it make sense, no matter how hard I tried. So, I never bought it. Science beats BS any day.
I checked out their website:
“Our most popular & most trusted ultrasonic bird repeller – emits sounds designed to disorient, intimidate, & confuse pest birds…”
Clearly that bird in the picture is totally confused.
I guess that bird isn’t a pest then.

In retirement, Tippi Hedren can’t get a break.
It’s not easy raising chicks on your own. This single mom used to have a choice of upscale trees, utility poles and light stands to make nests, but in her twilight years, things have gotten tight and she has no choice but to raise her offspring in the suburbs dangerously perched atop doodads and thingamabobs.
“I do what I can.” sighs Betty the Bird.
That’s a $556.75 nest support you have there, $20 more if it’s a 220/240 volt model.
Perhaps they should have added their bird repellent gel to the top of the box, only an additional $36.50 for a 3-pack.
Maybe it’s a cheaper, non-working dummy model, like they have for security cameras.
Maybe it’s actually a dummy bird on top that does the repelling.
(A fearsome dove, at that!)
a lonesome, dove, too
There’s certainly one thing missing. In the upper right hand corner, where it says, “Place strobe light here”.
Add that, a sprinkler, and a sound tape of explosions, and that contraption just might work. Maybe add some barbed wire, just to be safe.
That bird is wise as a serpent.
And not particularly guileless.
QB-4 must be a subsidiary of ACME.
Clearly this shows that given the selection pressure in the environment from ultrasonic sounds the birds have evolved to cope with it. I predict that soon we will have mighty flocks of tone deaf pigeons plaguing our cities, listening to Eurovision song contest winners.
I am waiting for the species identification. Come on, people, this is a biology web site.
Appears to be a Mourning Dove, Zenaida macroura.
Oh, here’s the science to show why this contraption is probably expensive rubbish:
Looks like this dove probably has a hearing range up to 11kHz, that is certainly not ultrasonic.
Thanks for that. Good information there.
This reminds me of the ultrasound deer horns some people in my family use. No evidence whatsoever that they work, then again the same can be said for prayer and they do that too…
After all, it can’t hurt, right? There’s no harm in trying.
Writing that just now, sent a shiver from my shoulders all the way down to my leg.
Haha, it is no coincidence that both deer horns and prayer serve to line the pockets of savvy businessmen con artists
The bird cannot read. If it could, this wouldn’t have happened.
A sad reminder of the vast illiteracy of birds.
It’s probably about as effective as the sonic snake-repellers I’ve seen advertised, or the water-filled plastic bottles that magically stop d*gs from crapping on lawns.
Perhaps they forgot to turn it on
