Steller sea eagles, also known as Steller’s sea eagles, are a magnificent species of birds of prey found in the coastal regions of northeastern Asia. Contrary to popular belief, these majestic birds do not abandon their eggs. In fact, they are known for their strong parental instincts and dedication to their young.
The Nesting Habits of Steller Sea Eagles
Steller sea eagles typically breed in late winter and early spring. They build large, bulky nests in trees or on cliff ledges, often reusing the same nest year after year. The female lays one to three eggs, and both parents share the responsibility of incubating the eggs.
The incubation period for Steller sea eagle eggs lasts around 35-45 days. During this time, the parents take turns sitting on the nest, ensuring the eggs are kept warm and protected. They are known to be fiercely protective of their nest and will aggressively defend it against any perceived threats.
Parental Care and Chick Rearing

Once the eggs hatch, both the male and female Steller sea eagles are actively involved in caring for their chicks. They provide food, shelter, and protection for the young birds until they are able to fly and fend for themselves, which typically takes several months.
The chicks are initially fed by their parents, who bring them fish and other prey. As the chicks grow older, they begin to learn how to hunt and forage for themselves, with the parents guiding and teaching them these essential skills.
Factors Affecting Nest Abandonment
While Steller sea eagles are generally known for their dedicated parenting, there are a few factors that can potentially lead to nest abandonment in rare cases:
-
Disturbance: If the nest is subjected to excessive human activity or other forms of disturbance, the parents may feel threatened and choose to abandon the nest to protect themselves and their young.
-
Food Scarcity: In the event of a severe food shortage or lack of available prey, the parents may be forced to abandon the nest in search of better foraging opportunities, leaving the eggs or chicks behind.
-
Predation: If the nest is threatened by predators, such as other birds of prey or large mammals, the Steller sea eagles may choose to abandon the nest to avoid being killed or injured while defending it.
However, it’s important to note that these instances of nest abandonment are relatively rare and the Steller sea eagle is generally known for its strong parental instincts and dedication to its young.
Conservation Efforts
Despite their impressive size and strength, Steller sea eagles are considered a vulnerable species by the International Union for Conservation of Nature (IUCN). Their population has declined in recent years due to a variety of factors, including habitat loss, pollution, and human disturbance.
Conservation efforts are underway to protect these magnificent birds and their habitats. Organizations like the IUCN and the National Audubon Society are working to raise awareness, monitor populations, and implement strategies to ensure the long-term survival of the Steller sea eagle.
Conclusion
In conclusion, Steller sea eagles are not known to abandon their eggs. These birds are dedicated parents who work tirelessly to incubate their eggs and care for their chicks until they are able to survive on their own. While there are rare instances where nest abandonment may occur due to factors like disturbance or food scarcity, the Steller sea eagle is generally recognized for its strong parental instincts and commitment to its young.
