Mr. Gould observes that the members of this genus are remarkable for their 
robust form and for their strength and magnitude of their bills ; and their habits

My specimens were obtained near Valparaiso in Chile. I saw it as far 
north as the valley of Copiapo. I was assured by the inhabitants that it is a very 
fierce bird, and that it will attack and kill the young of other birds.
