The shikra, a small bird of prey, is known for its distinctive throat features. Its throat plays a crucial role in its breathing, vocalizations, and hunting abilities. In this comprehensive blog post, we’ll delve into the fascinating details of the shikra’s throat and explore its significance in the life of this remarkable raptor.
The Shikra’s Throat Anatomy
The shikra’s throat is characterized by a dark but narrow mesial stripe, which is a unique feature of this species. This stripe runs down the center of the throat, adding to the bird’s striking appearance. The throat is also visible when the shikra is in flight, with the male displaying a light wing lining (underwing coverts) and blackish wing tips from below.
The shikra’s throat is an essential part of its anatomy, as it is responsible for several vital functions:
-
Breathing: The throat is the primary passage for air to enter and exit the shikra’s respiratory system, allowing the bird to take in oxygen and expel carbon dioxide.
-
Vocalizations: The throat muscles are used to produce the shikra’s sharp, two-note call, which is a key part of its communication and territorial behavior.
-
Swallowing: The throat is involved in the process of swallowing food, as the shikra uses its beak to capture and consume its prey.
-
Flight Mechanics: The throat muscles also play a role in powering the shikra’s strong and agile flight, enabling it to hunt and navigate its environment effectively.
The Shikra’s Hunting Prowess

The shikra’s throat is closely linked to its hunting abilities. These birds of prey are known for their exceptional hunting skills, which were once commonly utilized in falconry in India and Pakistan. The shikra’s throat muscles and overall anatomy allow it to execute swift and precise movements during the hunt, making it a formidable predator.
Sexual Dimorphism in Shikras
Shikras exhibit sexual dimorphism, meaning that the males and females have distinct physical characteristics. This is evident in the differences between their throat features:
- Males: Have a red iris and a dark but narrow mesial stripe on the throat.
- Females: Have a less red (yellowish orange) iris and a brownish upperpart, as well as heavier barring on the underparts.
These differences in throat and other physical traits help distinguish the sexes and play a role in their social and reproductive behaviors.
Shikra Nesting and Breeding
Shikras are monogamous birds, forming pairs for life. Both the male and female participate in building the nest, which is a platform similar to that of crows, lined with grass. The female typically lays a clutch of 3 to 4 eggs, which are pale bluish-grey with black stippling on the broad end. The incubation period lasts 18 to 21 days.
During the nesting and breeding process, the shikra’s throat plays a crucial role in feeding the young. The male brings food to the nest, and the female uses her throat to feed the chicks, transferring the prey from her beak to theirs.
Conservation Status and Threats
The shikra is not currently facing any major threats, but the loss of its native habitat and illegal trading may pose serious risks to the species in the future. According to the IUCN Red List, the total population size of the shikra is around 500,000-999,999 mature individuals, with the European population consisting of 50-210 pairs and the Arabian population consisting of 600 breeding pairs.
Conservationists and birdwatchers alike are working to protect the shikra and its unique features, including its distinctive throat, to ensure the continued survival of this remarkable bird of prey.
Conclusion
The shikra’s throat is a fascinating and integral part of its anatomy, serving vital functions such as breathing, vocalizations, and hunting. The unique characteristics of the shikra’s throat, including the dark mesial stripe and its role in sexual dimorphism, contribute to the bird’s striking appearance and remarkable hunting abilities. As we continue to learn more about these remarkable raptors, the shikra’s throat remains a captivating aspect of its biology and a testament to the wonders of the natural world.
