Does anyone have experience in using ultrasonic bird repellers? Do they work
or are they just a fancy gadget that actually does very little or nothing?

I need something that won't disturb my neighbours' and rid my large tree of

Have you considered a Daisy? I once relocated a flock of geese from my

plinks in the ass and the whole clan left.

No way! That tree provides shade for the entire front of the house. It would
cost me more for electricity if the tree was gone than it would be to buy
another tree or to clean up after the birds for that matter.

Another one of those people who wants nature to bend to their own
personal requirments. Duh!! It doesn't work like that. Birds, the
tree, the sun, the soil, bird poop, nature, etc, all work in a perfect
symbiotic relationship that needs nothing from you. The sun does not
quit shining and birds do not quit roosting, eating, and pooping
simply because you are inconvenienced.

Now that I cogitate on it awhile, I think your only real solution is
to kill yourself.

It's a tree. They are birds. That is what birds DO. You nicely provided
a place for them to roost, and now you want to chase them off?

Short of cutting down the tree, nothing much you can do that will work
on a long-term basis. I'd say get a cat, but their mess is even more
disgusting than what the birds leave. Plastic owls, shiny pinwheels,
etc, work only until the birds figure out they aren't really a threat.
As a kid, we used to put giant nets over the cherry trees so we could at
least keep part of the crop from the birds, but it was a major PITA and
not real pretty when in place.

If you knew what species the birds were, you might be able to find a

I'm not sure how effective such are, either, long term. And, of course,

Starlings, for example, are terribly persistent about roosting--scare
them up at eventide and they'll simply circle and return unless are
extremely persistent and often even then a large number will eventually
just ignore noise, movement, etc., once dark sets in.

Yes, it is a tree and they are birds but for some reason there are many
times more birds this spring than ever before. We are not feeding them and
there is no reason that I can see that they would come to our tree when
there are many trees in the neighbourhood that even have feeders attached to
them.

The usual number of birds (+ pr -) is ok and not a problem but this is
ridiculous.

Some neighbours of ours tried them but the effect wasn't long lasting. The
many orchards in the area use cannons that give a boom at irregular times
but that isn't practical in an urban setting for obvious reasons.

There are many cats in the area but they have proven to be next to useless
in bird control as they must be well fed and therefore not interested in
birds.

when you stretched it. It might also be the reflection moving around in

You have a handle on the problem that we face. We have been on the look out
for nests in the tree and there are none but if I find any in the future
they will be gone in a hurry.

All I can do it seems is to hope that they move on to some other

I must have walked in the barn thousands of times without the fake Owl
and the birds didn't give a ****. They were used to people walking in and
out since the barn was used to store tools and hay among other things.
Walk in with the stuffed Owl however and they scattered as fast as they
could.

Differently trained crowd, then... they don't give a crap here about
owls, stuffed or the real thing but will scatter on movment. And, the
barn here is used daily w/ much traffic as well.

I've always been surprised the owls don't even bother w/ the young 'uns
when they're just beginning to move about but they don't.

The hunting instinct in any self-respecting cat is separate from the
need to eat. I've had many domesticated cats, and many of them killed
almost daily. A cat who doesn't love to hunt needs psychiatric help.

Forget ultrasound.

Turn on a loud shop vac. Once they get used to that, use the shop vac
noise to mask the sound of you plunking the birds (starlings?) with a
nice pellet rifle. No one will hear a thing over the vac.

Next questions:

If you walked through the barn with the owl-on-a-pole every time you needed
something out of the barn, would the birds in there eventually get used to it
and ignore it?

If you permentantly mount the thing, won't they get used to it and ignore it
even faster?

We have Red Tailed Hawks around here that love toy dog breeds. A
Chihuahua wrapped in a tortilla would be a fine meal for little kiddie
hawks.

We have them as well as golden eagles and kites but there are certainly
no dogs that small that are outside dogs around here. They would simply
get lost in the native grasses and never be able to get thru it at least
before something got 'em whether it was raptor or rattlesnake or badger
or coyote or... .

_IF_ one were to take a mind, I doubt your Pom would have a chance 'cuz
he'd get taken from the rear and his neck/back snapped before ever had a
chance to put up a fight.

I think it's highly unlikely they would take it for several reasons,
though, the first being there are undoubtedly far more prevalent and
familiar targets of somewhat lesser size and one wouldn't like the (I'm
guessing) more or less constrained area around a house as an attack site
that would make for difficult flight path out. Also, while I don't know
for sure, I suspect they're watchful enough and cognizant enough to
recognize an obstruction like the leash as being a no-no for a target in
general.

They are pretty impressive, granted -- 'til you put one up besides one
of the golden eagles, anyway...

I _HATE_ the da-d kites, though...them *******s dive bomb ya' from the

Jeff The Drunk wrote:
....

That's odd. Or is mine odd? Either way I was told and always believed
that a big Owl would scare smaller birds.

Out in the open along towards dusk time I'm sure they do--but owls are
nocturnal and generally move in daytime only to avoid being themselves
disturbed, not to do damage to anything else. Other than that, as far
as I can tell having watched them for 50 years or so I don't think they
pay any attention to the other at all. I'm quite sure the fake
stationary owls have no benefit after the first change in a location for
a few days at most for most birds, anyway. An active dummy that did
something towards dusk that might look threatening, maybe, but other
than that, I think not, meself based on my observations.

The horned owls roost in the cedars by day and only begin to rustle
about about a half-hour or so before sunset; then just at dusk they'll
depart on the night's adventure. They'll be back on one of their
favorite roosting spots for disposing of the kill at daybreak (top of
the silo is one, a particular power pole is also a popular alternative)
and then not long after the sun is well up they'll be gone only to be
seen during the day if happen to get too close to where they are that
particular day and disturb them.

The barn owls are much more reclusive -- except for the pair currently
nesting in the barn, one rarely sees them at all; they do not come out
until well after it is really dark and they're back in their nesting
sites well before daybreak as well. Only because the loft in the barn
is open does it disturb them when go in there. The upper levels of the
elevator are only accessed on rare occasions when actually have some
need but last year there were at least three different pairs raising
owlets I saw and I don't know how many other pairs might have been back
in areas that are not easily seen w/o effort. Once in a while if come
home late at night will see the outline of one flit by as the headlights
disturb it, but mostly we know they're there by the pellet droppings and
sounds they make during the day.

OTOH, horned owls are territorial and only one pair occupies a general
area at a time. The young leave after about a year to find their own
territories while the barn owls seemingly are pretty convivial and are
limited only by nesting sites and food supplies, apparently.

Interestingly also w/ the horned owls, the male and female mate
permanently, but do not have any association with each other except
starting in the mid-winter roughly courting season and thru nesting.
The brood is not all of the same age, either, they are "stairstepped"
apart by a couple weeks to month--quite a sight to see three or four in
a nest, each a bigger copy of the next younger...

Ultrasonic devices dont work on birds, neither do fake owls, hawks,

The full frequency range of what each person can hear varies slightly.


In Europe, I believe, they sell these things to specifically drive off
young people from loitering and causing a nuicance. It's based on the
general fact that adults lose most of the hearing sensetivity that
they had in their youth, so it's supposed to irritate kids while having
no effect on adults.

I'm glad they don't do that here.

Some people, like me, are sensitive to those frequencies. They cause my
ears to ring and hurt like hell.

I'd hate to be your neighbor if you were to put those damned things up.

You can hear Ultra sound?? That is supposed to be beyond the limits of human
hearing.

The full frequency range of what each person can hear varies slightly.


In Europe, I believe, they sell these things to specifically drive off
young people from loitering and causing a nuicance. It's based on the
general fact that adults lose most of the hearing sensetivity that
they had in their youth, so it's supposed to irritate kids while having
no effect on adults.

I thought that was called Beetoven.

I'm glad they don't do that here.

Ultrasonic devices dont work on birds, neither do fake owls, hawks,
and snakes. What did work for me is a box that makes various bird
warning sounds but this may disturb the neighbors or maybe not.

OWL to be working, owls must be hunting the birds in that region. Animals do not fear from other animals in a predefined context.

And sounds, which may work for a specie might not work for others.

So, for example, in a closed hangar or workshop, why would pigeons stay in? Coz of shadow, shelter, and stable heat/wind i assume.

Do you own a hose and is your water pressure good. If so spend some time annoying them with the hose. It has to be a high pressure single stream that you can hit them with. A sprinkler etc they will like, but the solid high pressure stream they will not like. You are unlikely to hit them as they move away quickly. When you stop they come back, but do it repeatedly and they will go elsewhere.

This is not an instant fix, nor a permanent one, it takes ongoing work on your part. You may be able to use multiple hoses on a timer to blast the tree every so often.
You can also try a catapult to shoot at them, the idea is constantly annoy them and they will perch elsewhere.

Unfortunately, 5 years ago, Worn Out Retread aggravated a flock of birds causing the flock to descend upon him and eat him alive. It was a real tragedy. He is survived by a wife, 3 ex-wives 32 children and 456 gerbils. The gerbils were inconsolable and committed suicide by running onto a freeway into traffic.(~_~
