A small sample of 5 augur buzzard weighed an average of while 22 birds averaged in wingspan. The adult augur buzzard is strikingly plumaged and essentially unmistakable if seen well.

tail that stands out strongly in contrast. The primary flight feathers are blackish and the secondaries off-white, both barred with black. Below the chin and around the throat is mainly white, and the rest of the underparts and the underwing coverts are rich rufous. The flight feathers from below are white, tipped with black to form a dark trailing edge to the wing. The juvenile augur buzzard is mainly brown above and rufous brown below and on the tail. It may be confused with the steppe buzzard (''Buteo buteo vulpinus''), a migratory subspecies of the

. However, the augur is considerably larger and bulkier with broader wings and a heavier flight style and an unbarred undertail. Although not as dark as the adult on the back and upperwing coverts, it is usually noticeably darker than a juvenile steppe buzzard. The adult augur buzzard has white underparts and underwings. The female has black on the lower throat. Juveniles are brown above and buff below, the underparts later becoming white. Juveniles are similar to juvenile jackal buzzards but are generally much paler below with bolder carpal patches and more clearly barred secondaries and tail. There is a melanistic form of augur buzzard, all black, except for grey and white flight feathers that are barred black and contrast strongly with the black center and a chestnut tail. About 10% of birds are melanistic, but the proportion rises in forested areas with high rainfall to as much as 50% in some areas. A somewhat similar melanistic morph of jackal buzzard is also known and these birds can be very hard to distinguish, perhaps only told apart by the stronger barring on the melanistic augur pale flight feathers. Dark morph long-legged buzzards may also be confused for melanistic augur buzzards but are clearly more slender in the wing, less blackish on the body and lack the bold rufous tail.Lendrum, A. L. (1979). ''The augur buzzard in the Matopos, Rhodesia''. Ostrich, 50(4), 203-214.

The Wellfleet Press. . The large (up to wide) stick nest is built in a tree or on a crag, and is often reused and enlarged in subsequent seasons. On average two (sometimes only one and rarely three) creamy or bluish white eggs are laid and incubated by the female only, although food is brought to her on the nest by the male. Augur buzzards exhibit variations in breeding behaviour that appear to correlate with their habitat. In agricultural sites, increased maternal care and paternal foraging results in larger broods and more prey deliveries to nests. Reduced predation pressure from conspecifics and other raptors in agricultural sites as a result of lower inter-/intra-specific interactions may enable the species to maximise provisioning of their young hence potentially increasing productivity. Conversely, in natural sites, males often take on a larger share of incubation while females focus on defending the territory. The eggs hatch in about 40 days.

is known to occur in augur buzzards. After a further 56–60 days the chicks can attempt flight. At 70 days they become independent of the nest, but young birds may then be seen with the adult pair for some time. As is the case in other tropical raptors, the clutch size is relatively smaller and the reproductive cycle is relatively longer than in related species found in the temperate zones. The diet of the augur buzzard is quite varied and opportunistic, as is typical of most ''
