Are there any asexual birds

Mate selection aside, birds copulate by the male passing his sperm to the female while their cloacas are joined. Birds do not have external reproductive organs separate from the cloacal opening. Birds then lay eggs in a protected place, typically in a nest that is either on the ground or above the ground in a bush or tree. Copulation must typically occur separately for each egg that is laid. The eggs are incubated for up to several weeks depending on the species of bird, before the chicks hatch.
