There’s one time when I saw a Stellar’s sea eagle and I never thought it would look so massive in person, especially when It flared its enormous wings out.
After that encounter, I conducted thorough research on this magnificent bird’s size. And I found out various impressive stats about their size.
So here I brought to you this compact article about the Steller’s Sea Eagles’ size.
So without further ado, let’s get into it.
Steller’s Sea Eagle Height/Length
Steller’s sea eagles are considered one of the most aggressive and powerful among the Accipitridae Family.
Now talking about the length or height (scientifically it’s called length but commonly known as height) of the steller’s sea eagle.
Firstly you must know how a bird’s length is measured. So bird’s length is the distance between the bill/beak tip to the tail tip.
Now there are various factors that affect the overall length of the bird. And measuring a bird’s length can be tricky.
Since the measurement is performed on a dead bird so there’s always room for errors.
Now to answer the burning question, on average the length of a steller’s sea eagle can range between 85 to 105 cm (2 ft 9” to 3 ft 5”).
They do show some kind of sexual dimorphism, on average males are relatively shorter than females.
The average male height in stellar sea eagles is about 89cm (2ft 11”) while female height averages about 100 cm (3 ft 3 in).
|Bird||Height Range||Average Height|
|Male Steller’s Sea Eagle||85 to 105 cm (2 ft 9” to 3 ft 5”)||89cm (2ft 11”)|
|Female Steller’s Sea Eagle||85 to 105 cm (2 ft 9” to 3 ft 5”)||100 cm (3 ft 3 in)|
Steller’s Sea Eagle Weight
The steller’s sea eagle is considered one of the heaviest eagle around the world leaving behind giants like Harpy and the Philippine eagle.
Now talking about the weight Steller’s sea eagle shows sexual dimorphism in the weight also. In general, females of this species outweigh males by some margin.
On average the male steller sea eagle’s weight ranges between 4.9-6.8kg (10.8 to 15.0 lb) while the female weight ranges between 6.2-9.5kg (13.7 to 20.9 lb).
If we talk about the average weight across the species of the Steller’s sea eagle then it is around 6.2 kg (13.78 lb) and 7.7kg (17.101 lb).
Now the weight can vary depending on various factors like region, scarcity of food, migration, etc.
|Bird||Weight Range||Average Weight|
|Male Steller’s Sea Eagle||4.9-6.8kg (10.8 to 15.0 lb)||6.2 kg (13.78 lb)|
|Female Steller’s Sea Eagle||6.2-9.5kg (13.7 to 20.9 lb)||7.7kg (17.101 lb)|
Steller’s Sea Eagle Wingspan
Now before we talk about the wings and wingspan. Let me first explain how wingspan is measured. So wingspan is basically the length between the wingtips when the wings are fully stretched.
On average, the Steller’s sea eagle wingspan ranges between 1.95 to 2.50 m (6 ft 5” to 8 ft 2”).
Now if we talk about the mean/average wingspan then it is about 2.1 or 2.2 meters (7-7.3ft).
Some sources show that these eagles have a wingspan larger than 2.5 meters (8.2ft) but it has not been verified yet.
|Bird||Wingspan Range||Average Wingspan|
|Steller’s Sea Eagle||1.95 to 2.50 m (6 ft 5” to 8 ft 2”)||2.1 or 2.2m (7 or 7.3ft)|
Steller’s Sea Eagle Bill And Talon Size
Now coming to the other body part sizes of the Steller’s Sea Eagles.
Firstly let’s talk about the bill size, steller’s sea eagles have one of the longest bills even surpassing the mighty Philippine eagle.
The bill size of the Steller’s sea eagle is about 11.7 cm (4.6 in) from the gape.
Now talking about the talon size of the steller’s sea eagle is around 2-3 inches (5-7.6cm).
These talons are very sharp and can easily pierce through human skin. So make sure to maintain a distance from these eagles (or any other eagles in general).
|Bird||Bill Size||Talon Size|
|Steller’s Sea Eagle||11.7 cm (4.6 in)||2-3 inches (5-7.6cm)|
Steller’s Sea Eagle Size Comparison To Human
Now, this is one of the most common queries among the bird enthusiast “How Big is It?” How does it compare to human beings?
Well on average, the human height is around 5.5-5.9 ft, and if we compare this with the height of the Steller’s sea eagle which is around 85 to 105 cm (2 ft 9” to 3 ft 5”).
They do seem tiny compared to us but when we compare our height and their wingspan (1.95 to 2.50 m (6 ft 5” to 8 ft 2”) we look way too small.
If we were to compare on the basis of weight then we’ll definitely win. Their average weight is around 4.9-9.5kg (10.8-20.9 lbs) while our average weight is around 60-80kg (132-176 lbs)
|Basis||Human||Steller’s Sea Eagle|
|Height||5.5-5.9 ft||2.9ft to 3.5ft|
|Weight||60-80kg (132-176 lbs)||4.9-9.5kg (10.8-20.9 lbs)|
|Wingspan/Armspan||5.3-5.9ft||6.5 ft to 8.2ft|
Steller’s Sea Eagle Vs Bald Eagle Size Comparison
Bald eagles are marginally smaller than the Steller’s sea eagle. The bald eagle has a wingspan of 1.8 and 2.3 m (5 ft 11 in and 7 ft 7 in), height ranges about 70–102 cm (28–40 in) and weighs around 3 and 6.3 kg (6.6 and 13.9 lb).
But when we compare it with the steller’s sea eagle then they’re larger in every aspect.
I’m creating a difference table below you can access it and compare both.
|Basis||Steller’s Sea Eagle||Bald Eagle|
|Height||2.9ft to 3.5ft||2.2-3.3ft|
|Weight||4.9-9.5kg (10.8-20.9 lbs)||3 and 6.3 kg (6.6 and 13.9 lb)|
|Wingspan||6.5 ft to 8.2ft||5.11ft to 7.7 ft|
Steller’s Sea Eagle Vs Harpy Eagle Size Comparison
Now comparing Steller’s sea eagle with one of the largest eagle (Harpy eagle). Let’s see what the outcome is:
Harpy Eagles have an average height of around 2.10ft – 3.6ft with a wingspan of around 5.9ft-7.5ft and they weigh around 4.4-8.3kg (9.7-18lbs).
So as you can see in some aspects they come close to the steller’s sea eagle and in some aspects, they are totally outnumbered.
|Basis||Steller’s Sea Eagle||Harpy Eagle|
|Height||2.9ft to 3.5ft||2.10ft and 3.6ft|
|Weight||4.9-9.5kg (10.8-20.9 lbs)||4.4-8.3kg (9.7-18lbs)|
|Wingspan||6.5 ft to 8.2ft||5.9ft-7.5ft|
That was everything you need to know about Steller’s sea eagles’ size. I hope this article was helpful enough and you got something useful from it.
I have tried to put as much information as possible.
