The gabar goshawk is usually considered to be sedentary, but immature birds are somewhat nomadic and some small migratory movements have been recorded in parts of its range. It is most frequently observed alone, but pairs are also common, particularly during the breeding season, when the male is often observed pursuing the female through trees, or calling from his perch. The small platform nest is typically constructed using thin twigs and positioned in a vertical fork in the crown of a thorny tree, such as an acacia. One notable aspect of their nest construction is that the birds collect spider webs including the live spiders, the spiders spin new webs which may help camouflage the nest, and the spiders may consume arthropods that would parasitize the chicks.

 

The eggs are laid from July to December, peaking in September to November. The normal clutch is two eggs, but up to four may be laid, and these are mainly incubated by the female for about 33–38 days. Once hatched, the chicks are brooded by the female for the first 19–21 days of their lives, while the male brings her food to feed to them. They leave the nest around 35–36 days old, becoming fully independent about one month later.

 

Small birds are the major part of the gabar goshwak’s diet, with small mammals, reptiles, and insects also taken on occasion. The prey is typically flushed from trees and caught following a persistent and energetic pursuit. The gabar goshawk sometimes hunts from the perch, swooping down to catch prey off the ground or in flight. They have also been recorded attacking the nests of colonial birds such as weavers by clawing their way destructively through the nest top to snatch the chicks from the nest.

 

Known predators of the gabar goshawk include tawny eagles, Wahlberg's eagles, and Ayres's hawk-eagles.
