What happened to the thrush without breeding

The thrush does not reproduce because the gender of the bird is the same, or it has not yet reached the breeding period.This bird searches for puppets and nests in spring, and then the female can produce eggs.Usually 3-5 pieces of each nest will be produced every day, and it takes about 14-15 days to incubate. It needs to be done by the female bird. The male bird will be alert to the surroundings.After birth, the chicks need to be fed by the pro -bird, and usually leave the nest when it grows up to 25 days.
