Plunge-diving birds have narrower and thinner rhamphotheca, resulting in different beak shapes. [6] Beak angle. The neck of plunge-diving birds is also unique. Plunge-diving birds can dive from heights up to 45 m and reaching speed up to 24 m/s without injury. Their neck plays a big role when plunge-diving.
Loons can live as long as 30 years and can hold their breath for as long as 90 seconds while underwater. [7] [8] Loons are migratory birds, and in the winter months they move from their northern freshwater lake nesting habitats to southern marine coastlines.
Seabird mortality caused by long-line fisheries can be greatly reduced by techniques such as setting long-line bait at night, dying the bait blue, setting the bait underwater, increasing the amount of weight on lines and by using bird scarers, [104] and their deployment is increasingly required by many national fishing fleets.
Geese and ducks are just two types of water birds, which include seabirds, shorebirds, waterfowl, and numerous other forms of birds. Video of gulls, ducks, and swans feeding on the Danube River in Vienna (2014) A water bird, alternatively waterbird or aquatic bird, is a bird that lives on or around water.
Plunge diving can be done from heights of 10–30.5 m (33–100 ft) and even up to 100 m (330 ft). These birds hit the water around 97 km/h (27 m/s) and can go to depths of 25 m (80 ft) below the water surface. Their skulls contain special air sacs that protect the brain from enormous pressure. [2] Prey are usually eaten while the birds are ...
Dives usually last less than one minute, but the bird swims underwater for distances of over 30 m (100 ft) on a regular basis. Diving depths up to 180 m (590 ft) have been recorded, [24] and birds can remain underwater for a couple of minutes.
Due to a declining population, experts from the International Union for Conservation of Nature (IUCN) included the bird on its Endangered Species There are Less Than 1,000 of These Birds Left in ...
Gannets can achieve speeds of 100 km/h (62.13 mph) as they strike the water, enabling them to catch fish at a much greater depth than most airborne birds. [ 5 ] The gannet's supposed capacity for eating large quantities of fish has led to "gannet" becoming a description of somebody with a voracious appetite.
