Here's why:
* Breeding season: Wolves are seasonal breeders, meaning they only mate during a specific time of year. This is usually aligned with the availability of food and favorable weather conditions for raising pups.
* Gestation period: The gestation period for wolves is around 63-65 days. By giving birth in late spring or early summer, pups have ample time to grow and develop before winter sets in.
* Food availability: Wolves need a lot of food to support themselves and their pups during the breeding season. This is why they typically mate when prey is most abundant.
It's important to note that this is a general timeframe. There can be individual variations within a wolf pack, and some wolves might mate earlier or later depending on specific circumstances.
