Nest care and brooding in sunbirds, which was previously believed to be solely performed by females, might involve the participation of males as well, according to our observation of a male Amethyst Sunbird with a brood patch during a ringing session in South Africa.
Nest care and brooding in sunbirds (Nectariniidae) is thought to be performed exclusively by females. Here, we provide the first evidence that male sunbirds might help with brooding. During a ringing session in Hoekwil, South Africa, we observed one male Amethyst Sunbird (Chalcomitra amethystina) with a brood patch. Its sex was confirmed using molecular methods, and our observation suggests that nest care in sunbirds may at least in some cases be biparental.
