birds are different than mammals
Like all birds, fish and mammals - they produce sexually. They need a male & a female to reproduce the species.
All mammals reproduce sexually. Pretty much all vertebrates (fish, birds, mammals, reptiles, amphibians) reproduce sexually. Only some bacteria, some plants, fungi reproduce asexually.
Of course they do produce sperms. They reproduce like mammals.
It differs in the way mammals and them birds. Mammals feed from their breasts. On the other hand birds go outside the nest to catch like slugs,worms,snails.
