Troupial (Icterus icterus)
Troupial or trupial is the national bird of Venezuela. The Troupial is fairly large in size, with a long tail and a bulky bill. It has a black head and upper breast. Troupials are obligate nest pirates, meaning they make no nest of their own, and are thus required to steal or occupy a vacant nest in order to survive. Troupials are capable of violent attacks against native nesters, and once they possess these territories they defend them fiercely against intruders. They may even ingest the eggs or young hatchlings of a newly acquired nest.
