The Socotra Cormorant (Phalacrocorax nigrogularis) is a threatened species of cormorant that is endemic to the Persian Gulf and the southeast coast of the Arabian Peninsula. Also known as the Socotran cormorant or Socotra shag, this bird is characterized by its striking appearance and interesting behaviors.
The Socotra Cormorant is almost entirely black and measures approximately 80 centimeters in length. During the breeding season, it exhibits a purplish gloss on its forecrown and a greenish tinge on its upperparts, adding to its allure.
This cormorant is well-adapted to its marine habitat and is known for its exceptional diving skills. It hunts for fish and other prey underwater, propelling itself with its webbed feet and using its specialized bill to capture its meals. The Socotra Cormorant is highly gregarious and often forms large flocks, particularly during roosting periods.
Unfortunately, the Socotra Cormorant faces significant threats to its survival. The species is considered vulnerable due to the limited number of breeding localities and a declining population. Efforts are being made to protect and conserve this remarkable bird and its unique habitat.
Key Takeaways:
- The Socotra Cormorant is a threatened species of cormorant endemic to the Persian Gulf and the southeast coast of the Arabian Peninsula.
- Also known as the Socotran cormorant or Socotra shag, it is characterized by its almost entirely black plumage and purplish gloss during the breeding season.
- This cormorant is highly gregarious and often roosts in large flocks.
- The Socotra Cormorant dives for its food and is well-adapted to its marine habitat.
- Due to limited breeding localities and declining population, the Socotra Cormorant is classified as vulnerable.
Distribution and Habitat
The Socotra Cormorant, also known as the Socotra Shag, is primarily found in the Persian Gulf and along the southeast coast of the Arabian Peninsula. This species also breeds on the Socotra islands, which are located in the Indian Ocean.
The Socotra Cormorant’s distribution spans across several countries within the region, including Bahrain, Iran, Iraq, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates. It is important to note that the breeding population is concentrated within the Arabian Gulf, with the largest nesting colony located on the Bahraini Hawar Islands.
This cormorant species is highly dependent on offshore islands for its breeding localities. These islands provide suitable nesting sites where the birds can build their colonies and raise their young. However, the decline in available nesting sites is a concerning factor that has contributed to the species’ vulnerable conservation status.

Behavior and Diet
The Socotra Cormorant is a highly gregarious species known for its unique behavior and diet. While there is limited information on its foraging habits, it shares some similarities with other cormorant species.
Like its counterparts, the Socotra Cormorant is an excellent diver, relying on its diving abilities to catch its prey. It is capable of staying submerged for up to 3 minutes, indicating its proficiency in deep diving.
Unlike many other cormorants, which predominantly forage near the surface of the water, the Socotra Cormorant has been observed foraging in mid-water. This behavior sets it apart from its relatives and reveals its adaptability to different foraging environments.
The Socotra Cormorant’s diet primarily consists of fish, making it a skilled fisherman. It hunts by diving underwater and pursuing its prey. Its fishing prowess is a crucial part of its survival as it relies on the availability of fish in its habitat.
This species displays a cooperative feeding behavior, often forming large flocks during both roosting and foraging. The birds may feed together, exhibiting a level of cooperation rarely seen in other cormorant species. This gregarious behavior not only enhances their chances of successful foraging but also strengthens their social bonds within the flock.
Overall, the behavior and diet of the Socotra Cormorant reveal its adaptability, diving prowess, and cooperative nature. These traits contribute to its survival and success as a species in its natural habitat.
Threats and Conservation Status
The Socotra Cormorant is classified as vulnerable on the IUCN Red List, indicating that it is at risk of extinction in the wild. The decline in its population can be attributed to several threats that jeopardize its survival.
Coastal development poses a significant danger to the Socotra Cormorant. The destruction and alteration of its natural habitat due to urbanization and infrastructure projects disrupt the species’ nesting and foraging grounds.
Disturbance caused by human activities, such as tourism and recreational boating, further adds to the vulnerabilities faced by the Socotra Cormorant. These disruptions can negatively impact their breeding success and overall population.
Marine pollution, including oil pollution, is a grave concern for the conservation of this species. The Socotra Cormorant’s reliance on coastal areas makes them highly vulnerable to the detrimental effects of oil spills. The Gulf War, in particular, had severe consequences, resulting in the decline of breeding colonies and further exacerbating their conservation status.
To safeguard the Socotra Cormorant and its breeding colonies, conservation efforts are imperative. The Bahraini Hawar Islands serve as the only protected nesting colony in the Persian Gulf, recognized as a Ramsar Convention listed site. However, to effectively mitigate the threats and ensure the survival of this vulnerable species, it is crucial to prioritize conservation actions and raise awareness about the importance of protecting their habitats and reducing human-induced disturbances.
