Controling Birds

My suggestion would be an Ultrasonic repellent system. It seems to be a very effective non lethal way to relocate unwanted pests.

or

You could treat the trees with this product. It seems to have good reviews as well. Just don't try to apply it on a windy day!!

Dear sir

do you have any experiance of this ultra sonic sound system ?

will it work properly

thanks wasantha.

Buy a realistic model of a bird of prey. Sounds too simple to work? Put it on the edge of a building and wait for another bird to turn up. And wait…and wait….

I used those on my farm, both owls and the yellow eye - They work well but need to be moved from time to time so that the birds don't become accustomed to it.

The fake owls and other birds of prey have to be moved periodically or get ones that have some action inherent in the decoy. Otherwise the birds get uised to them. sounds of guns or other such bang producers work for a while, if they dont annoy the workers or neighbors too much. If the problem is life threatening, you can do what JFK Airport does. The airport is located adjacent to a wildlife sanctuary. JFK has a falconer on staff, who flies teathered hawks to scare the birds but not actually attack them. They have gone as far as only using non natural hybrids so as to deter some complaints of capturing wild birds. The airport has to go to this extreme, as a bird ingested in a jet engine can be catastrophic. (to both the bird and the plane)

When I worked at Raytheon, they had this probelm and solved it with a sound system that periodically played predator bird sounds over a loud speaker. I'm sure it's something commercially available. You can add a predator decoy (like an owl) for good measure - they have animatronic ones now. Also, I've heard rubber snakes work well - but you have to move them araound from time to time.

1) Cut the trees down.

2) Raise cats.

Next step, plague of cats. have you ever tried herding cats?

That's when you bring in the alligators.

Herding cats is easy. It's those dang short ponies you have to ride. Keep draggin my feet.

Platform horseshoes?

<Platform horseshoes?>

------------

I once saw a horse wearing platform horseshoes. Pretty classy ones too, with shimmering pink and purple sequins. But when I noticed it was also wearing fishnet pantyhose, I realized that this was the same damned transequus someone had spotted earlier heckling our mares down in the South Forty.

What (lock n load) is the world coming to?

If I was a flock of birds flying round looking for something to land on, thated scare the crap out of me for sure!

<have you ever tried herding cats?>

Have you ever tried managing software developers?

Only one way to do that……………..blow their bloody heads off!

I seem to remember hearing this form a farmer one day;

"If it moves shoot it, if it doesn't chop it down!"

You have to admit that it would work.

Sounds like the "Wal Footrot" approach, when "Footrot Flats" first appeared in the Courier Mail in the mid 70s I thought it was Aussie, probably because the strips were well chosen (see a tree and reach for the chainsaw), but of course Wal, Dog, Pongo et. al., are actually Kiwis. It would have worked fine for Wal too, apart from Couch sheltering all the vermin. Now that was a good cartoon strip.

"If it's a wealthy Republican attorney, shoot it. If it's not, chop it down!"

-- Dick Cheney

I don't know about the ultrasonic thing but I've heard that the fake predators and sounds do help. Haven't tested them or seen them used myself though.

The other option of playing shotgun blasts on loudspeakers also works. The downside of that is if a human drops dead from a heartattack after hearing the shot. Seriously, I've witnessed this technique. Understandably, they only trigger it manually after giving a warning to the people close by.

Thanks All for good answers , And thanks CR4 for gave me this opportunity;

I will try one of this and let you know the result

I live in a region known for it's grapes and wine. The farmers around hear use what we call clackers. I have never actually looked at one, but I do know this little bit:

The clackers work on propane. They are timed explosions, and they are louder than a shotgun blast. But don't blow yourself up!!

The idea of playing a recorded shotgun blast seamed like it wouldn't be loud enough. You could just play an old western, or an action flick if that was the case.

Years ago I lived in a mountainous region of the U.S. known for its excellent peaches, and lately, its vineyards. Farmers there used propane-powered noisemakers which seem to fit your description. They looked like a motorcycle megaphone-style exhaust pipe mounted atop a propane cylinder. I don't recall anyone ever calling them "clackers," but I do know they were very effective at driving away pests. Birds and bears, mostly.

You know what? I could use one of these myself!

Seems I have a graveyard-shifting day-sleeping moron living upstairs who refuses to turn down his TV at night no matter how politely one frames the request. And as Mr. Manners sleeps during the day while everyone else is at work, the poor sod must surely find the interminable silence nearly deafening. Surely one of these running in apartment while I'm at work might serve as a gentle reminder that he is not alone?

Years ago I lived on a farm where we grew corn. In late summer and early fall giant flocks of black birds would show up and attempt to destroy the crop. I am talking flocks of close to a million birds. You can imagine the damage one of these flocks would do. We come up with an effective method of control. It involves some early mornings and late nights. It works like this. You get up at 0-early o-clock, take a couple three people with you. Each carries a shotgun with 5 to 6 boxes of shells. Go hide in the corn. Shoot the damn birds all day long and into the night. Quit worrying about being a goodie goodie and kill them. After about three years of good shooting the flocks left and have never returned.

Three years? Your approach sounds a bit labor intensive, to say the least. For a flock that large I'd definitely try a different approach - like taking the time to learn how to build an FAE - a Fuel-Air Explosive - and then actually building one. It would certainly take less than three years and, done right, it won't ruin your crop. I guarantee that it'll knock the wind out of those birds! Hehe.

My distant second choice would be to use a Daisy Cutter. Just a wee bit hard to find, however, but well worth the effort.

Sounds like your second choice would be kind of rough on the corn and anything else within a quarter mile radius.

Hmm...do you really think so?

Not only that, but I'm sure that once I actually lit the thing off, the corn might be the least of my worries!

After using a fuel-air explosive, you can then bag the corn and sell it directly to the movie theaters. Already popped corn.

<After using a fuel-air explosive, you can then bag the corn and sell it directly to the movie theaters. Already popped corn.>

When we take into consideration the tremendous heat and overpressures generated by thermobaric explosions, I have a hunch our product isn't gonna be popcorn. On the other hand, maybe the movie theatres might not object to our trying to sell them toasted corn flakes without the milk.

For my part, I think we're looking at this whole thing all wrong. Why are the birds there to begin with? I say get rid of the pond/corn/what-have-you and the bird problem will take care of itself. Besides, I never liked working in sales anyway.

Pigeons can be a real problem as well. Here's how we solved ours.

There is a product called "Bird Scare Flash Tape". It reflects sunlight and makes a fluttering noise in a slight breeze. The combination scares the birds away. Google it or check www.johnnyseeds.com.

I'm kind of partial to the kinetic energy method, but you have to know what's behind your target! That failing, I've seen plastic owls and falcons work but the birds do become oblivious to their presence after a while - then you have to move them around. Worst case, you go back to the shotgun! You could try a real bird of prey, but that could get pricey.

The problem may take care of itself. I lived at an apartment complex in Florida with a pond. It had muskovy ducks that were constantly hatching ducklings, but the place was not overrun with ducks. I remember my grandmother's place being so overrun with ducks that the homeowners association had to take action to eliminate them. But here nature was handling the problem. The hens were lucky to raise one out of a brood of 10-15 to maturity. At first I thought it was the turtles in the pond eating them, but they looked like a plant eating variety, not snappers.

What I eventually found out was that a great blue heron, that visited the pond daily, terrorized the ducks at night. Walking the hedges, bushes and flower gardens while making a low whooping sound, it would stir up the ducks and provide itself with a meal of ducklings, the mother hens squawking in futile protest.

At work we had a covered parking lot. Pigeons would roost in the roof structure with predictable results for the cars. They installed a heated wire system to discourage the pigeons from roosting above the cars. I recall watching a pigeon roosting on one of the wires, alternating feet while holding out one to cool. So while it reduced the problem, it did not go away.

An interesting aside is that of the dozens of species of wild ducks, only two have been domesticated. The muskovy is a South American breed that is little different from its wild ancestors. While they can make a lot of noise, they don't quack. All other breeds of domesticated duck were derived from the mallard.

You can try hanging nylon gill net in the trees . A very small number of birds die entangled in the net and the remainder leave the area after seeing the corpses .

Fishermen throw out old nets and these are used where I live in British Columbia on small farms and the technique is widely used in boat shelters to deter pigeons .

How about a couple of Carpet Snakes? Now if anyone knows how to get rid of Flying Foxes or the Greenies that protect them, I might just get some mangoes this year.

I had that problem here in Australia in Sydney, had big flock of Starlings used to land in a large gum tree [ Eucalypt ] that was over & adjacent my above-ground pool and B-B-Q & tables area, etc. & make a huge mess over everything and squawk & make a lot of noise as they settled in for the night .

As they came into roost in the tree just on dusk I took the B-B-Q plate which was about 2 ft X 3 ft X 1/4" steel off the B-B-Q held it with one of the two handles welded to the ends & rapidly wacked it with a small ball peen hammer on the back, the loud metallic penetrating noise sent them flying off, as soon as they came back I did it again & again to scare them off.

After a few days of this they didn't come back to my tree. The following days I saw them on dusk come flying in, wheel around overhead and roost in another big tree a few blocks over from my property, but NOT in my tree anymore.

Got rid of my problem in a few days by giving it to someone else !! Bet they hated me !!

The Cure.

How about setting up a couple of cameras with spherical mirrors as in the diagram below.

Then you feed the camera images into some really smart software that can recognize the birds that you don't want there, triangulate their position, then using a couple of stepper motors position a small laser and POOF no more unwanted birds.

And yes I obviously have way too much spare time on my hands.
