Harpy Eagle
Harpia harpyja
The upperside of the harpy eagle is covered with slate-black feathers, and the underside is mostly white, except for the feathered tarsi, which are striped black. A broad black band across the upper breast separates the gray head from the white belly. The head is pale grey, and is crowned with a double crest. The upperside of the tail is black with three gray bands, while the underside of it is black with three white bands. The irises are gray or brown or red, the cere and bill are black or blackish and the tarsi and toes are yellow. The plumage of males and females is identical. Voice: This species is largely silent away from the nest. There, the adults give a penetrating, weak, melancholy scream, with the incubating males' call described as "whispy screaming or wailing". The females' calls while incubating are similar, but are lower-pitched. While approaching the nest with food, the male calls out "rapid chirps, goose-like calls, and occasional sharp screams".

Rufous-breasted Sparrowhawk
Accipiter rufiventris
A small raptor, with a height of about 30 cm and wingspan of 72 cm, the rufous-breasted sparrowhawk is named for its distinctive rufous-coloured underparts, which can be seen both perching and in flight. It is dark grey slate-brown above, including the head, with a black bill and eyes that are yellow at all ages. In flight, the bold bars on both its wings and tail are clearly visible. Juvenile plumage ranges from the rufous-color of adults to more white, but all have feathers with dark shaft streaks on their underside. Voice: Its call is a series of high, fast "kew" notes, with the male being higher-pitched than the female. A more drawn out "kieee-u" is made by the female to request food from the nearby male, and is adopted by the young as a begging call whenever adults are near.
