Dipper

life science Maturity 11-13 Next article →

Dippers are unique members of the bird family Cinclidae. They belong to the genus Cinclus. Most songbirds, or passerines, stay above the water. However, dippers are special because they can dive and swim underwater.

They get their name from a characteristic bobbing or dipping motion. They often perform this movement when perched beside the water. This behavior makes them easy to recognize in their natural habitats.

These birds have many physical adaptations for life in fast-moving water. Unlike many other water birds, they do not have webbed feet. Instead, they have relatively long legs and sharp claws. These allow them to grip rocks firmly in swift currents. Their bones are solid to reduce buoyancy, which helps them sink. Their wings are short but have strong muscles. This allows them to use their wings like flippers while swimming.

To stay dry and see clearly, dippers use several biological tools. They have very dense plumage, or feathers. A large preen gland helps them waterproof these feathers. When they dive, small bubbles trap a thin, silvery film of air on their feathers. They also have nasal flaps to prevent water from entering their nostrils. Their eyes have well-developed focus muscles. These muscles change the curvature of the lens to improve underwater vision.

Staying underwater requires a lot of energy and oxygen. Dippers have a high concentration of haemoglobin in their blood. This allows them to store more oxygen than other birds. Because of this, they can remain submerged for 30 seconds or more. Their basal metabolic rate is also much slower than other birds of similar size. This rate is approximately one-third slower than typical terrestrial passerines. One small population even feeds underwater at a hot spring in Siberia when temperatures drop below -10°C.

There are five distinct species within the genus Cinclus. These include the white-throated dipper and the brown dipper. The American dipper and the Mexican dipper are also members. The fifth is the white-capped dipper. The rufous-throated dipper is also part of this group.

Most species are dark brown or nearly black. The rufous-throated dipper is unique because it has a reddish-brown throat patch. A 2002 molecular phylogenetic study used DNA to study these species. It found that the white-throated and brown dippers are sister species. It also showed the Cinclidae family is closely related to the thrush family, Turdidae.

History shows how humans have viewed these birds over time. The genus Cinclus was introduced by Moritz Balthasar Borkhausen in 1797. The name comes from the Ancient Greek word "kinklos." This word described small birds that lived near water. In Britain and America, some dippers are called water ouzels. This name comes from an old word for the Eurasian blackbird. In the past, people in Scotland and Germany even paid bounties to kill them. They wrongly thought dippers harmed salmon fish stocks by eating eggs.

Dipper life cycles involve specific territories and nesting habits. Pairs establish linear breeding territories along rivers. The size of these territories depends on how much food is available. Territories can range from 500 meters to over 2,000 meters. They build large, round, domed nests made of moss. These nests often have a grass cup inside. They build them in tight spaces like crevices or under bridges. The white-throated dipper can live for over 10 years. An American dipper was recorded living for 8 years and 1 month.

Today, conservation is important for the survival of dippers. They depend on fast-flowing rivers with clear water. Water pollution and erosion can threaten their homes. Building dams and reservoirs can also destroy their habitats. Most dipper species are of least concern. However, the rufous-throated dipper is considered vulnerable. Its population is small and declining, especially in Argentina.
