বিপন্ন সৈকতের পাখি | Endangered Shorebirds | Episode 333 | by Nature and Life

Situated by the Bay of Bengal, the world’s largest delta Bangladesh has a vast shore. Silt, carried with upstream waves, has accumulated here to create countless coastal chars. The vast shore and coastal chars remain lively with various species of birds. In winter, apart from indigenous birds, a vast number of migratory birds visit the chars. Some species of these native and migratory birds are aquatic and some roam the shore of water bodies. They are called Shorebirds. Among them are various species of Plover, Godwit, Curlew, Seagull, Tern, Sandpiper, etc. Their chirpings and liveliness make the coastal islands full of life. Such scenes of hundreds of birds taking flight, landing on the water, or just splashing in the water is extremely enchanting. However, for many reasons, including scarcity of food and habitat, most Shorebird species are now endangered. A small shorebird, Plover is now endangered. They roam at salt water beaches, river estuaries, or sand dunes. These restless birds fly in small or large flocks. The Black tailed plover is one of the endangered indigenous shorebirds. Hundreds of Plovers roam together in muddy banks of the shore or shallow waters. Various Sandpiper species make up another group of Shorebirds. Common sandpiper, Green sandpiper, Curlew sandpiper, Ruddy turnstone roam among other groups of shorebirds. Though they were once common in Bangladesh’s coast, they are now decreased. In winter, the globally endangered Spoon billed sandpiper migrate to the coastal chars of Bangladesh. At low tide, small groups of Sandpipers spend time foraging in the wet shore. Another endangered Shorebird is Black-headed ibis. Its body is white, but throat, head, and curved beak are black. In winter, they are seen perched by the water shore. Like the Ibis, Pied avocet is another bird with long beak and is also endangered. The black beak is slender and curved upwards. Black stripes on pure white body have made them more attractive. They also roam in groups and forage on the shore. Among the other Shorebirds, Common greenshank and Redshank are also endangered. Their long slender colored legs have earned them such name. Their long beak’s front is slightly curved upwards. They mostly roam the coastal sand dunes. Seagull and Tern are prominent among our aquatic shorebirds. Bangladesh has about 18 species of Seagull and Tern. Among those Seagull, Black-headed gull and Pallas’s gull roam the coastal shores. Also, a number of Tern species, including Little tern, River tern and Gull-billed tern are also seen on the coastal shores. Most of these Seagull and Tern species are endangered. In search of prey they fly near the water. Sometimes, a flock of Seagull would stand and rest by the shore. Indian skimmer is another member of the Seagull and Tern family. In winter, Indian skimmer visit the coastal regions of Bangladesh and a few other select places. This bird of long attractive orange-yellow colored beak is also endangered. Especially, the shore and sand beds are their habitat and breeding ground. These Shorebirds play vital role in the ecosystem. Yet their habitat and breeding ground are being damaged by our unmindful and adverse activities. The coastal chars are becoming unsafe for the Shorebirds. Also, climate change, water body pollution, and fishing nets on the shore have threatened some Shorebirds’ existence. So, Shorebirds can be conserved by creating public awareness. By ensuring healthy coastal ecosystem, it is possible to conserve the endangered Shorebirds as well as ensure a healthy environment.
