Are you fascinated by the world of raptors like the eagle? If yes, then you are in for a treat! Today, we will have a look at one of the most majestic birds of prey hailing from southern America. The crowned solitary eagle (Buteogallus coronatus) is also known as the Chaco eagle, but did you know that this bird isn't related to the African variant of the crowned eagle?

A very small population of this threatened species lives in Argentina, Brazil, Paraguay, and Bolivia and the birds in Brazil and Argentina have especially been crucial for studying this species. The crowned eagle gets its name from the crown-like feathers present on its head. Don't be fooled by the silvery charm of this bird, as it is an exceptional hunter that is mainly active during the twilight, making it semi-crepuscular.

A crucial time in the life of these birds is the breeding season, as this is a monogamous species. Most birds will only lay one egg, and their nest is usually made high up in the trees. The male takes care of feeding the chick as well as collecting food for the female bird during this breeding season. Unfortunately, the population of these beautiful birds has declined drastically, and it is only found in some parts of South America, like in the eastern or central regions, today. One of the main threats to this species is human activities, including cutting down forests and trees.
