Steppe eagles, a species of Aquilae, are known for their unique nesting behavior and incubation patterns. Unlike their counterparts, the golden eagles, steppe eagles do not typically abandon their eggs during the incubation period. In this blog post, we will explore the nesting habits and egg-laying behaviors of steppe eagles, providing a comprehensive understanding of whether they abandon their eggs or not.
Nesting Habits of Steppe Eagles
Steppe eagles are predominantly ground-nesting birds, preferring to build their nests on the ground rather than in trees or on rocky outcrops. This nesting behavior sets them apart from the golden eagles, which are more likely to abandon their nests if disturbed by human activity.

Steppe eagles typically lay one to four eggs at a time, with the female incubating the eggs for approximately 45 days. Unlike some other raptor species, steppe eagles are not prone to cainism, a behavior where the first-hatched chick kills its siblings. As a result, each nest usually produces two or three fledglings, which are capable of leaving their parents’ care around 60 days after hatching.
Comparison with Golden Eagles
In contrast to steppe eagles, golden eagles are more sensitive to human disturbance and are more likely to abandon their nests during the incubation period. Golden eagles lay one to three eggs, with two eggs being the most common, and the eggs are incubated for 35 to 45 days. Nestlings fledge at 9 to 10 weeks and remain in the vicinity of the nest, with the parents providing food for the fledglings until they are around 14 weeks old or older.
Factors Affecting Egg Abandonment
While steppe eagles are generally not prone to abandoning their eggs, there are a few factors that can influence this behavior:
- Disturbance: Excessive human activity or presence near the nest can potentially cause steppe eagles to abandon their eggs, though they are less sensitive to disturbance compared to golden eagles.
- Food Availability: If the steppe eagles are unable to find sufficient food to sustain themselves and their offspring, they may abandon their nest and eggs in search of better foraging opportunities.
- Predation: The presence of predators, such as foxes or other raptors, near the nest can also lead to steppe eagles abandoning their eggs in an effort to protect themselves.
Conclusion
In summary, steppe eagles are generally not known to abandon their eggs during the incubation period, unlike their golden eagle counterparts. Steppe eagles are ground-nesting birds that typically lay one to four eggs, which are incubated for around 45 days. While they are less sensitive to human disturbance than golden eagles, factors such as excessive disturbance, food scarcity, and predation can still lead to steppe eagles abandoning their nests and eggs in some cases.
