There is an echo, it's just that the echo sounds almost exactly like their quack that it fools people.\n\nI'll put up a link to Mythbusters ... Meh, aren't any decent ones.  Look at Snopes instead.

Could be a coyote...they make all kinds of really creepy dog-like sounds, and I think they're not too rare in Nova Scotia...the second link is a page with a bunch of recordings of different coyote sounds.

If it looks like a duck and quacks like a duck, it probably is a duck.\n\nIt's a scam.

Yeah, all ducks have webbed feet, although in some species the webbing isn't as complete and can be harder to see.\n\nBut the birds you saw are almost certainly coots. Your description fits them to a 'T' in both size, colouration and behaviour. Coots are vicious greedy little buggers.\n\nHave a look at the links below to see if they look familiar

yes becasue he run firewall on his OS, i mean check the advanced tab in the firewall settings and go to advanced, the check the ICMP settings check the incomming echo request. it should work, otherwise turn off the firewall.\n\nBye

Actually, no it doesn't. The sound you hear is actually vibrations in your ear that your brain converts to noise. So if there are no living creatures with ears and brains around to 'hear' it, it does not make a noise...just some air vibrations going all over the place.

In Duck Hunt in particular for the original NES The gun is really a kind of cheapass camera that looks for the ducks to flash when you pull the trigger. The ducks flash within a square. The threshhold brightness is not being reached, or the code for the duck is not able to refresh on the plasma screen fast enough to signal the gun.\n\nDuck A might be:\n. ...\n\nDuck B might be:\n.. ..\n\nDuck C might be:\n... .\n\nHow many ducks can there be?\n\nYou may be able to check if it's a brightness issue by holding it right up to the screen.

The sound produced by the larynx of a duck, the sound we know as quacking, is of high amplitude but low frequency. Due to the low frequency the sound does not carry very far.\nAs an echo is the return of sound, from a far object, to its original source, the sound waves must travel to the object and back again.  It is therefore not possible for the sound from a duck to travel a long enough distance to produce any kind of echo.

It seems to have been adapted from the phrase 'to play for love (of the game)' (that is, to play for nothing). Although the theory is often heard that it represents the French word l'oeuf an 'egg' (from the resembance between an egg and a nought) this seems unlikely. But the cricketer's 'duck' is another matter.

Hide a duck in their explanation? I don't know if that's a metaphor or what but I have to say, never heard that one before! Lol. Anyway, I think it's just laziness why people don't read all the details. They want to be the first to answer, even if it means missing some important details in the process. Doesn't make much sense considering it would make their answer better if they read the whole question, but that's just the impression I got. Reading isn't all that hard - all you have to do is move your eyes, and take in the information. More people should try it lol.

As mentioned before this isn't true. What they found on Mythbusters is that while a duck's quack does have an echo it actually sounds very similar to the original quack so it blends in and can be hard to hear.

You read that on a Snapple cap, didn't you.\n\n"A duck's quack doesn't echo" is a much quoted scientific myth. In spring 2003 it was quoted on Home Truths on BBC Radio 4 and Shooting Stars on BBC 2. You can listen to our sound files on Home Truths by going to the BBC4 web site and "listening again". Recently, Salford Acoustics was the source of the story being presented in the national and international media when we proved that a duck's quack does echo as part of the British Association Festival of Science.\n\nClick here to hear Daisy getting into the Christmas spirit (mp3 player needed and a suspension of musical taste)\n\nSo what is an echo, and does it happen to a duck's quack?\n\n\n\nTrevor and daisy (from right to left) \n(c) Manchester evening news\n\nWhat is an echo?\nAn echo is a loud sound reflection that arrives late and so is heard as a separate sound source. Echoes can sometimes be heard in large concert halls, for example. Sound takes a long time to travel from the stage to the rear wall of the concert hall, if a strong reflection comes back from the rear wall to the front of the hall, this can be heard as an echo. To prevent this problem, it is common to apply diffusers to disperse the sound. Another common place to hear echoes is in some railway stations, making announcements hard to understand.\nThe term echo also refers to the physical sending back of sound or other waves and the repetition of sound by reflection.\n\nThe right hand animation needs a flash player.

Those annoying birds are probably American Coots.\n\nIn southern California the golf courses have a history of hiring a hunter to remove the birds when they become a problem.

No, birds are stimulated to sing based upon what they hear, not what they see- the bird song is made specifically for this, so that potential mates and/or potential intruders on territory are aware of each other even though they are not in sight.
