Like most owls, the Seychelles scops-owl is nocturnal and is only encountered during the day if it is disturbed at its roost. It has been observed to appear from beneath rocks suggesting this is where they roost. During the night, their acute hearing and large forward-facing eyes enable them to prey on lizards, insects, and possibly tree-frogs, which are common in their habitat. They also consume some vegetation (2).
During mating, the Seychelles scops-owl apparently emits a high-pitched whistle. This is often heard during the wetter months, from October to April, when food supply is highest and most Seychelles land birds breed (2). Fledged young have been seen in November and June, suggesting either a twice-yearly breeding cycle, or perhaps a very extensive breeding season (2) (4). The nest, which was not discovered until 1999, is situated in tree holes between seven and 25 meters. A single egg is laid, which is unusual for scops-owls which normally lay two, but characteristic of Seychelles land birds (6).
