In this clip, little sound is produced the first five times that the bill is opened (it varies, might be less or more) - this is sometimes termed the 'pumping' phase and is where the bird is taking in air in readiness for the next phase. The main, very low-frequency, 'boom' sound is then heard; in this clip, it's when (or slightly after) the bill is opened for the sixth time, and then again for the next three openings. As to why you can't hear anything - that could be for a number of reasons, eg.: 1. the sound may've gone out of sync with the image, perhaps due to some local internet or wifi issue (I usually resolve this by restarting the app, or sometimes restarting the viewing device). 2. Most often though, the reason is that the small speakers on certain devices just cannot reproduce the low-frequency sounds that these birds produce (or the sound settings on the device are set so that low-frequency sounds are filtered out). There may be other reasons too; all I can say is that the sound is still on the clip - I've definitely not deleted anything! :) Thanks for watching the video! I hope you do manage to eventually hear the booming!
What a magnificent bird!!! 😍 Magical beauty 😍🐦
Love the bittern, nearly outdone by the cetti's warbler, nice mix of reedbed sounds 😊
With that great mix of bird call, he can't get a boom in edgeways.
Sounds off at about 1:18 sounds kinda like an oboe for the peoole who arent sure what their looking for.
incredible .... exactly like a cow such a small bird
Allegedly one of the inspirations behind the bunyip
Another world 😊
I can hear a chorus of birds around it - but when it shudders then opens & closes its beak I hear nothing 😐

Thanks - I turned my phone up as high as it would go but obviously it was not high enough to hear the 'booming'
That type of heron sounded like a giant cuckoo (Canadian Goose in background)
Where's the boom then
1:18 approx - although may not be audible on a small-speakered (eg. mobile) device.
Sounds like a muffled oboe if that helps
Like waiting for paint to dry...
Shut up.. go play with your iphone
