This is a large strong form, with a long bill and strong tarsi, 

 belonging, no doubt, to the Teeniopterince, but simulating the true 

 Tyrants in colour and crest. D'Orbigny found it breeding in the 

 chambered nests of Anumbius acuticaudatus, which it appropriated, 

 and laying pale rose-coloured eggs spotted with reddish.
