The Steller’s Sea Eagle is a huge raptor native to eastern Russia. Males average 6 kg in mass and females outweigh the males with an average of 9kg in mass. The female’s wingspan is about 136 cm and the male’s about 118 cm. These birds usually communicate with a deep, barking cry, while during mating their call more closely resembles a loud, gull-like call.
An interesting fact about the Steller’s Sea Eagle… they have been known to remove mammals from commercial traps set by humans during harsh winters. This doesn’t make the trappers happy, but my guess is that the mammals are thrilled!

What do I consider if I want to build or buy bird house?
The Steller’s Sea Eagle habitat was constructed in 2010. A good bird house, simulates the perfect natural home for cavity nesters, not only to provide protection, privacy and comfort but also to meet individual species biological requirements and preferences, too. When purchasing or building a bird house please consider:
- Diameter of the entrance hole should be between 1 and 1.25 inches. Too small and no one fits in. Too big and guests you don’t want, like squirrels
- Easy to Install, Maintain & Clean
- Access to the inside of your nest box is important. Look for a hinged side or lifting roof to make clearing nests between broods much easier.
- No Perches! Perches are totally unnecessary for the nesting birds and may actually help predators gain access.
- Sloped and Extended Roof
- A sloped roof extending over the front and sides, is a nice feature and may help keep out driving rain and stop predators who get on top of the house from reaching inside.
- Untreated wood and unpainted interior, with rough surface to help nestlings climb.
- No rusty or exposed hardware like screws or nails protruding.
- Thick walls, at least 3/4″ and watertight seams.
- Ventilation with a 5/8″ hole on each side wall near the top.
- Drainage holes in the bottom to drain any moisture away from the inside.
- Durable enough to last several seasons.
- Location and number of houses
