Steppe eagles are known for their adaptable and varied diet, which changes with the seasons and their location. During the summer, they primarily feed on ground squirrels, while in the winter, they switch to a diet of insects and small birds. The frequency of their feeding can vary, but it is estimated that a steppe eagle may need to consume around 1600-2200 termites per day to meet their energy requirements.
Steppe Eagles’ Seasonal Diet Shifts
As the seasons change, so too does the diet of the steppe eagle. During the summer months, when ground squirrels are abundant, these birds of prey focus their hunting efforts on this primary food source. However, as the winter approaches and the ground squirrels become scarce due to the eagle’s migratory patterns, they must adapt their diet to include other available prey.
Summer Diet: Ground Squirrels
In the summer, steppe eagles are known to be particularly adept at catching ground squirrels, which make up the bulk of their diet during this time of year. These small rodents are a plentiful and nutritious food source for the eagles, providing them with the energy they need to thrive during the warmer months.
Winter Diet: Insects and Small Birds
As the ground squirrels become less available in the winter, steppe eagles shift their focus to a diet of insects, such as termites and locusts, as well as small songbirds. This change in diet is a necessary adaptation to ensure the eagles can continue to meet their energy needs during the colder, leaner months.

The frequency with which steppe eagles feed can vary depending on the availability and abundance of their preferred prey. However, based on their size and hunting techniques, it is estimated that a steppe eagle may need to consume around 1600-2200 termites per day to meet their energy requirements.
| Prey | Estimated Daily Consumption |
|---|---|
| Ground Squirrels (Summer) | Varies based on availability |
| Termites (Winter) | 1600-2200 |
| Small Birds (Winter) | Varies based on availability |
This suggests that steppe eagles may need to feed relatively frequently, especially during periods when their preferred food sources are abundant. They may spend several hours each day hunting and consuming their prey to ensure they have the energy they need to survive and thrive.
Opportunistic Feeding Behavior
In addition to their primary prey, steppe eagles are also known to engage in opportunistic feeding behaviors. They have been observed stealing the prey of other raptors, such as hawks and falcons, when given the chance. This behavior allows them to supplement their diet and take advantage of food sources that may not be readily available through their own hunting efforts.
Conclusion
Steppe eagles are adaptable predators that adjust their diet based on the season and their location. During the summer, they primarily feed on ground squirrels, while in the winter, they switch to a diet of insects and small birds. The frequency of their feeding can vary, but it is estimated that a steppe eagle may need to consume around 1600-2200 termites per day to meet their energy requirements. Additionally, these birds of prey are known to engage in opportunistic feeding behaviors, such as stealing the prey of other raptors, to supplement their diet.
