It has been observed that during breeding season when there is an increased demand for energy intake owing to egg-laying activities, they tend to consume larger preys like rabbits or snakes.

In conclusion, The Cape Verde barn owl is one among few predatory bird species that can survive solely on eating smaller animals such as rodents or insects found within its range. Though, their diet might change in accordance with the breeding season and food availability, they are well adapted to digest all parts of their prey including bones and fur. Their nocturnal hunting behavior coupled with an excellent hearing ability makes them a fascinating subject for research on avian biology.

Reproduction And Breeding

The Cape Verde barn owl is known for its remarkable breeding behavior. These birds are monogamous, meaning they mate with only one partner throughout their lifetime. They usually breed once a year, and the timing of their breeding season depends on the availability of food.

The female lays 2-4 eggs in a clutch and incubates them for around 30 days before hatching. The male provides her with food during this time to support both the mother and the chicks. Once the chicks hatch, both parents work together to feed and care for them until they fledge at around six weeks old.

Interestingly, Cape Verde barn owls exhibit communal roosting behavior during non-breeding periods. Several pairs may share a large roosting site, where they will rest and socialize together until it’s time to breed again. This could potentially be an adaptive strategy for protecting themselves from predators or conserving energy.

Breeding success can vary depending on factors such as habitat quality, food availability, and predation risk. However, overall, Cape Verde barn owls have shown resilience in adapting to changing environmental conditions and maintaining stable populations over time.
