👉 Trixagus is a type of bird in the family Ardeidae, commonly known as the swallow or thrush. They are typically large, with wings that fold down and can be long and slender, and have a distinctive crest on their head called the "trixhyal" which is used for flight. Trixaguses are known for their song-like vocalizations, often resembling those of birds such as swallows or ravens.
