Seal Breeding Habits

Mating Season at Donna Nook

In Lincolnshire, a remarkable phenomenon occurs every year during the seal breeding season, where thousands of grey seals migrate to the coastline, creating a popular wildlife spectacle. The mating season starts in November, reaching its peak in December1. Grey seals return to the same beach each year, recognising it as a suitable location for breeding2. This incredible event, allows everyone to marvel at the fascinating breeding habits of these impressive mammals.

Grey Seal Pups

During the pupping season, grey seals give birth to their pups near the sand dunes3. It is a thrilling experience to witness the birthing process as well as the nurturing of the furry newborns. The mother seals tend to their pups for approximately three weeks, during which time the pups grow rapidly. The pups’ white, soft fur, called lanugo, keeps them warm in the cold weather, and their thick layer of blubber insulates them further4.

Here are some interesting grey seal pup facts:

  • The average birth weight of a grey seal pup is around 14kg5.
  • Pups gain weight rapidly, reaching 40-50kg within three weeks6.
  • Grey seal pups are weaned by their mothers at 18-21 days old7.

After the weaning process, the pups shed their white fur and develop a waterproof pelage, similar to that of adult seals8. Once the pups are strong enough, they venture out into the sea to begin their independent life. Simultaneously, adult seals mate and prepare for the following pupping season, marking the end of one cycle and the beginning of another9.

Seal Behaviour and Interaction

Mother and Pup Bonding

At Donna Nook, thousands of grey seals migrate to give birth to their pups in the sand dunes. During this time, a strong bond forms between the mother and pup. When pups are born, they have a distinctive white coat, which helps them blend in with the surrounding environment. The mothers are very protective and will keep a close eye on their pups throughout the day.

Mothers take care of their pups by nursing them with fat-rich milk, which is crucial for the pup’s development. This milk is approximately 53% fat, enabling the pups to grow rapidly during the bonding period. After about 18-21 days, the pups start to shed their white coat and gain their adult waterproof fur.

It is important to note that human interaction should be kept to a minimum during this critical bonding phase. If a mother seal feels threatened or senses danger, she may abandon her pup. This makes it vital for visitors to Donna Nook to maintain a respectful distance from the seals and their pups.

Bull Seals Conflict

While mother seals are occupied with bonding and taking care of their pups, bull seals engage in territorial conflicts. Male seals, known as bulls, arrive at Donna Nook during the breeding season to establish their dominance over a specific area in the hope of mating with females.

These conflicts often take the form of harsh physical confrontations, including biting, vocalising, and intense body posturing. As a visitor to Donna Nook, it is not uncommon to witness such battles between bull seals.

Bull seals will compete for proximity to female seals, attempting to maintain large harems of females. This behaviour can lead to aggressive encounters among bulls, which may result in injuries and, on rare occasions, death.

In conclusion, understanding the behaviours and interactions of Donna Nook seals is essential for appreciating the marvel of nature. The incredible bond between mother seals and their pups, as well as the formidable conflicts between bull seals, reflect the seals’ instinctive urge to ensure the survival and success of their species. Additionally, by maintaining a respectful distance, we can allow these beautiful animals to continue living and thriving in their natural habitat.
