Facts about this animal

With a length of 80 cm and a body-weight of 1.2 kg, this is the largest tiger-heron. It has yellow-green facial skin and orange iris, and differs from other species of the genus by its bare yellow throat.

Bare-throated tiger-herons use to stay motionless for long periods of time at water's edge, with the neck outstretched diagnonally, waiting for prey, including fish, frogs, crabs, and insects. The bare-throated tiger heron usually nests solitarily. 2 to 3 eggs are laid, which are dull white tinged with green and eventually with not very distinct brown spots.

Did you know?
that Bare-throated Tiger Herons display an interestimg courting behaviour? According to observations in the wild the courting birds face each other with necks and bodies horizontal and feathers fluffed up, like gamecocks spoiling for a fight, one of them then advances a few steps, at the same time raising bill and neck vertically and emitting some hoarse roars, beofre retreating to its first position. The second bird remains motionless but mimicks the other's body movements and calls as if hypnotized.
