Shikras are small raptors found in a variety of habitats, including forests, farmland, and urban areas. They are known for their wide-ranging movements, with some populations traveling up to 3000 km during their migrations. But how far do shikras typically travel from their nests on a daily basis?
The Daily Movements of Shikras
According to a study conducted in an urban park in Bengaluru, India, shikras were observed to travel an average of 1.2 km from their nests during the day, with some individuals traveling up to 2.5 km. These movements were likely driven by the availability of food, as the study found that the shikras’ movements were correlated with the abundance of their prey.
Shikras are opportunistic feeders, consuming a wide variety of prey items, including:
- Rodents
- Squirrels
- Small birds
- Small reptiles
- Insects
- Carrion
They have been observed to descend to the ground to feed on emerging winged termites and to hunt small bats at dusk. Their ability to travel significant distances from their nests allows them to take advantage of these diverse food sources.
Shikras’ Nesting Habits

In terms of their nesting habits, shikras build platforms similar to those of crows, which are lined with grass. Both sexes help build the nest, with twigs being carried in their feet. The breeding season in India is in summer, from March to June, and the usual clutch is 3 to 4 eggs. The incubation period is 18 to 21 days.
Shikras’ Migratory Patterns
While shikras are known to travel significant distances from their nests on a daily basis, some populations also undertake long-distance migrations. Studies have shown that some shikras can travel up to 3000 km during their migrations.
These migrations are likely driven by a variety of factors, including:
- Seasonal changes in food availability
- Changes in weather patterns
- Breeding and nesting requirements
By traveling long distances, shikras are able to take advantage of the changing availability of their prey and find suitable breeding and nesting sites.
Conclusion
In conclusion, shikras are small raptors that are known for their wide-ranging movements. On a daily basis, they can travel up to 2.5 km from their nests in search of food, taking advantage of a diverse range of prey items. Some populations also undertake long-distance migrations, traveling up to 3000 km to take advantage of seasonal changes in their environment.
