The bare-throated tiger heron (Tigrisoma mexicanum) is a wading bird of the heron family Ardeidae, found from Mexico to northwestern Colombia, with one recorded sighting from the United States in Hidalgo County,Texas. It is 80 cm (31 in) in length and weighs 1,200 g (42 oz).
This large species is found in more open habitats than other Tigrisoma herons, such as river and lake banks. It waits often motionless for suitable prey such as fish, frogs or crabs to come within reach of its long bill.
This is a solitary breeder, not normally found in heron colonies. The nest is a small flattish stick platform in a tree into which 2–3 green-tinged white eggs are laid.
