Seasonal breeder facts for kids
Some animals are called seasonal breeders. This means they only have babies during certain times of the year. These special times are usually when conditions are best for their young ones to survive and grow. Things like the weather, how much food and water is available, and even how many predators are around can affect when they choose to breed.
When Animals Reproduce
Female seasonal breeders have a special time when they can have babies. This is called being "in season" or fertile. During this time, they are naturally ready to mate. At other times of the year, they are not interested in mating or having young.
Male seasonal breeders also change with the seasons. Their bodies get ready for breeding. For example, male greater sage-grouse actually gain weight. This helps them prepare for the spring breeding season.
Seasonal breeders are different from other animals. Opportunistic breeders can have babies whenever conditions are good. They don't wait for a specific season. Also, they are different from continuous breeders, like humans. Continuous breeders can have babies all year round.
Breeding in Groups
Many animal species breed together in large groups. This is called communal breeding. You can often see huge groups of these animals during their breeding seasons. These large breeding areas are very important. They are often protected by wildlife conservation laws. This helps keep the species from becoming extinct.
Some animals have learned to breed only in these big groups. They cannot have babies in smaller numbers or just as a pair. If these large breeding groups are disturbed, the animals can be in danger. For example, if they are hunted too much in their breeding areas, they might not be able to reproduce.
The Passenger pigeon is a sad example. It was once one of the most common birds in North America. These pigeons needed to breed in huge groups. But they were hunted so much in their breeding grounds. They could not breed in smaller numbers, and so they became extinct.
