Certain birds can search for food by diving underwater in addition to flying and swimming. Hesperornises, who lived during the Cretaceous epoch, were the first birds to dive. This ability is still retained by a large number of birds today. Of course, ducks and the whole duck family are the most prevalent. Certain ducks have the ability to dive to very deep depths and remain submerged for extended periods of time.

1. Penguin
A penguin is a big seabird that does not fly. Penguins are great swimmers and divers, and they can go down to depths of up to 20 meters. They can also hold their breath for up to 18 minutes.

2. Shearwater
With a body length of up to 48 cm and a wingspan of up to 73 cm, shearwaters are huge seabirds. Their heads are black and their bodies are white. Shearwaters are skilled divers and have the ability to fly underwater. 180-meter depths have been reached to see these birds.

3. Gannet
With a wingspan of 150 cm and a body length of up to 90 cm, the gannet is a waterfowl the size of a goose. With a characteristic pointed beak, gannets are good divers with a maximum three-minute underwater stay.

4. Puffin
Duck family members, puffins are tiny birds with sharply serrated beaks. Puffins dive up to twenty meters with remarkable skill.

5. Ruddy Ducks
The duck family includes the Ruddy Duck as waterfowl. Ruddy Ducks, which have a maximum body length of 58 cm, are skilled divers who can descend to a depth of 10 meters and remain submerged for one minute in order to capture mollusks.

6.Auk
Auks are little seabirds that can reach a maximum body length of 35 cm and a maximum wingspan of 50 cm. These birds are easily recognized by their large, rounded beaks. Auks are exceptional divers; they can swim underwater by using their wings, and they can steer with their legs.

7. Fulmar
Large seabirds, fulmars can grow up to 91 centimetres in length and have a one meter wingspan. Fulmars dive exceptionally well, reaching depths of up to 25 meters from heights of 10 to 100 meters. They can travel at up to 140 km/h in the water.

8. Cormorant
With body lengths of 50 to 100 centimetres and wingspans of up to 150 centimetres, cormorants are medium-sized seabirds.

9. Goose
Large members of the duck family, geese are distinguished by their enormous proportions and lengthy necks. Similar to ducks, geese can dive, but they do it far less effectively. Geese spend most of their time on land.

10. Kingfisher
With a wingspan of 25 cm and a weight of 45 grams, the kingfisher is a little bird that is somewhat larger than a sparrow. Fish that kingfishers catch by diving underwater is their food source. Perched on branches above the water, they wait for their meal before diving for the fish.
