Crowned Eagle
Stephanoaetus coronatus
The crowned eagle is a very large eagle. Measuring from 80 to 99 cm (31 to 39 in) in length, it is the fifth longest extant eagle in the world. The female, at a weight of 3.2–4.7 kg (7.1–10.4 lb), is around 10–15% larger than the male, at a weight of 2.55–4.12 kg (5.6–9.1 lb). An average body mass of 3.64 kg (8.0 lb) was given in one account. Elsewhere, an average of 3.8 kg (8.4 lb) has been claimed. Slightly smaller weights were found in a South African survey where 5 males averaged 2.65 kg (5.8 lb) and 8 females averaged 3.71 kg (8.2 lb).

Dark Chanting Goshawk
Melierax metabates
The dark chanting goshawk is a medium-sized, bulky hawk with an upright stance. The head, breast and upperparts are essentially dark grey, while the underparts, other than the breast, are white, finely barred with black. The wing primaries are black, and the tail has broad black and white bars. The cere and the long legs are orange-red. The female is, on average, larger than the male, weighing up to 840g to the male's maximum weight of 700g. Voice: As its common name suggests, the dark chanting goshawk is a vocal bird, although less so than its two congeners. It often calls from a perch or in flight, making an accelerating series of piping notes and fluty whistles, which has been described as a song or chant and there are up to a dozen notes in a series peeu-peeu-pu-pu-pu. It also gives a high-pitched peee-u.
