The hand-reared male used at least three different vocalizations in the display context, with each one produced in the same stereotyped and repetitive structure as the normal display sounds. The imitations were produced during the males' advertising display. These sounds have been described before, but were never analysed in any detail and went so far unnoticed by researchers of vocal learning. A hand-reared individual imitated a slamming door and a human voice, and a female-reared individual imitated Pacific black duck quacks. Here, we provide evidence for vocal learning in a member of a basal clade of the avian phylogeny: the Australian musk duck ( Biziura lobata). For birds, oscine and some suboscine songbirds, parrots and hummingbirds demonstrate this ability. As you are saying the word “ White” into the call, move your middle finger slightly away from blocking the hole and it will produce the “gather up” call of a bobwhite quail.Acquiring vocalizations by learning them from other individuals is only known from a limited number of animal groups. Say the words “ Bob, Bob, White” into the call. This will force all the air/sound to come out the top hole. With your hand, hold the outside edge of the bell end with your thumb and ring finger and use your middle finger to block the hole in the end of the call. Place the mouthpiece between your lips and hold it with your front teeth. Never make the screeching sounds they make while flying, as this is an alarm call. When calling wood ducks, always mimic the sounds they make while resting on the water. Say the word “ TooWheeeeeeeeeet” into the call to produce the contented whine of a wood duck. Place the mouthpiece loosely between your lips and hold it with your front teeth. The cadence should be varied and erratic – “ chirp (pause) chirp-chirp (pause) chirp”

Repeat this several times to sound like a greenwing teal. Place the mouthpiece between your lips and hold it with your front teeth and let out the smallest sharp burst of air possible making the call produce a “chirp”. Do this several times to sound like a flock of noisy wigeons. Your emphasis should be on the WE syllable. Place the mouthpiece loosely between your lips and hold it with your front teeth and say the words “ who WE who” into the call.

The cadence should be somewhat erratic – Peep, (pause) peep, (pause) peep-peep-peep Make short bursts of this trilling sound to sound like a group of pintails. To make the pintail sound, blow into the call while rolling your tongue to make a trilling sound that kind of sounds like a short blast from a police whistle.

This will mimic the raspy quack of a drake mallard. Another method is to hum or buzz the word “ Whaaaat” into the call. Say the word “ Dweeeeet” into the call as deeply as you possibly can. Place the mouthpiece of the call between your lips and hold it with your front teeth.
