Anhingas are large birds with wingspans of 109 cm. Though they are usually found in marshes, you can find them flying where they can reach thousands of feet above sea level. While flying, Anhingas soar in the air hardly needing to flap their wings. https://www.allaboutbirds.org/guide/anhinga/id
Anhingas are nicknamed "Water Turkeys" because of their swimming abilities. Since they can swim deeper than any other bird, they dive into the water to stab fish with their bills.
