Low powered Laser, why a GREAT success in BIRD control?

You can't see the beam? They probably do!

You ever tried point a low powered laser pointer (even 1mw) near a pigeon or other birds?

(i really hope you didnt and never do, directly, with high powered lasers, to this poor animals)

Well, this just scare the s**t out of them, and they take flight immediately..i mean, you just point the cheap laser on their side, and ALL THE GROUP takes off immediately..leaving the area as fast as they can.

If you never did the experiment, try and notice the reaction.. i recommend using a standard 1mw red laser pointer, commonly used for presentations, and to not hit the animals in the eyes. but just make the point to move near their area... you will be surprised!

The only possible explanations is that their seight is able too see wavelenghts and intensity that human cannot... so they just see the beam of a low powered 1mw red laser pointer, in full day, while we just barely see it, in full night with lots of fog.

Is just courious that while cats and dogs, gets crazy to catch the point, birds instead, just cant wait to leave the area as fast as possible (not just to move a few steps away, but really change state or something!)

I tried a 200mw red on a couple of magpies, they just chased it around.
So I got the shotgun :whistle:

*Don't worry, I didn't blind them!

Can't say i've ever used a laser on a bird before. Lead, yes (damn crows) but lasers, no.

i tried my 1w on some squirels and crows and they ran so fast like theyd been shot at and didint come back. i baught another one and im mounting this one to my rifle with a pressure switch

Cats are hunters, birds are prey, they will run away from protential predators, a cat will attempt to catch it.

I beamed my 1-watt 445nm(indigo-blue) up at the top of a high tree and an entire flock of pigeons? bats? starlings/sparrows all bolted up out of the tree and were chirping and shrieking ... haha ... pretty impressive ... definetly bird-control tech. i'd say ...

I tried this last week with a couple of ravens that were in my co-workers pickup truck bed digging in the trash. I was using my red laser, defocused greater than 15'. I was about 20' out and they saw the red dot on the snow and took off not to return. My co-worker was impressed and happy they didn't come back to continue digging in his trash...

Will have to repeat this again later! More testing IS required.

Some animals reacts in strange ways to light spots approaching ..... i tried red and green with the ducks dhat are on the lake, near where i live ..... approaching them with a red spot, they look it, maybe move a bit, but no other ..... approaching them with a green spot, they fly away all scared in group before the spot reach them.

Also some airport uses green scanners for bird control, i've seen.

Interesting, I would call that a biological field test for frequency response in birds. Apparently their vision is more reactive to the higher frequency(green vs red) just like humans. :)

It is such a joke.
I saw a 5mW red specifically for bird control and the thing looked like a pistol, had a "head" over 1.5" diameter and cost something like $1000...
An animal control guy I know was getting 5mW greens for $270+ and they are just a pen style like the ebay cheapies.
I am supplying him now and to hell with those other fraudulent goofballs.

"NOTE: Using lasers to harass birds is not cruel or inhumane because unlike the human eye, a birds eye will not be injured by high power portable green lasers."

Ummm.... What? Someone care to explain because my common sense bullchit meter is redlining...

Because if it looks like bullshit, and smells like bullshit... well, it's definitely not going to be a cheeseburger..

Just because of this...smell... i just went to lib. take a look a biology book about birds eyes.

As i was suspecting by their reaction, they see different colors at different wavelength, even they see UV much better than other species, also their view system is supplied (by mother nature inc.) with 4 cones, one of with works like a 8x zoom (amazing!), definitively an optical one (ok, no one is laughing..but this may happen a little later).

Also they can see much more frames than us, just around 200fps, this is useful when you try to catch a bug while YOU and HIM, are both flying.

They have a special layer of oil outside, that cover the pupil, this is a sort of chemical filter, and is suspected that this may allow them to see more colors than we do with and extended gamma of shadows and details, over the limit of 16M...thats explain very well why they can see lasers and any intensity and wavelenght that we cant, and their strong reaction to such a weird beam of light.

That's explain also why they go often to balcony..they are probably trying to watch our TV from the windows to have fun realizing how miserable is our color reproduction and frame rate.

Infact, the book ends explaining that "prrrr...prrrr..." translated into bird language means "eheheheh..."

And no, i find nothing about a shield for 200mw green laser shoot into eyes, so it is definitively not a fishburger (much more appreciated by birds, than cheese).

Thanks for doing that research! I get the joke about the 8x optical zoom ;-)

My thoughts then would only conclude that because they have MORE rods, cones and generally a more advanced optical system than we do, it would be even that much more dangerous to a bird to have a laser pointed at it than a person.

Unless their blink aversion reflex is SO fast that it would take a 50 or 100 mw laser to do damage, however it seems to me that some birds wouldn't know to look away and might be curious what that bright light is that is shining in their eyes...


Anyway, it as wicked lasers that posted that... Something to be said about... Well... You can make up your own minds on this one.

Critical missing info from what I've read above? What time of day was the red laser used? I don't know about you, but, I need to see the red dot in order to aim the red dot. That said, I've tried aiming the cheapo red laser at about where I think they can see it and, depending on the bird, they kinda' shrug it off, or pause as if wondering "wtf is that?" But do they scoot? Not really. So, color me skeptical.
