Can bird get pregnant without male?
Unauthorized use is prohibited. Though rare in vertebrates, parthenogenesis occurs in sharks, rays, and lizards.

How do birds lay eggs without a mate?
On occasion, a solitary bird may lay a clutch of eggs and then sit on them as if they were fertile. This is why many people recommend leaving the eggs in the cage with the bird. However, more frequently, the bird lays one egg after another, usually ignoring the eggs that are laid.
Are birds asexual?

What animals mate with themselves?
Most animals that procreate through parthenogenesis are small invertebrates such as bees, wasps, ants, and aphids, which can alternate between sexual and asexual reproduction. Parthenogenesis has been observed in more than 80 vertebrate species, about half of which are fish or lizards.
Can a bird reproduce without a male?

Can humans reproduce asexually?

What can impregnate itself?

Can a woman get pregnant without a man?
