Accipitridae

Accipitridae is an animal family in the Accipitriformes, birds with small to large sizes, bent beak as a morphological adaptation for food, prey on insects to mammals, carrion and some eat fruit, found on all continents and a number of island groups in the oceans with several migratory species.

Accipitridae has well-known members including hawks, eagles, kites, harriers and vultures. The sizes and shapes vary with a length of 23-120 cm, a weight of up to 14 kg and a wingspan of 39-300 cm. Most have sexual dimorphism in size with larger females.

Dlium Accipitridae


Beak strong and bent. Bird hunter species generally have a long and skinny shape, whereas species that hunt large mammals have thicker and stronger tarsi, whereas snake eagle tarsi have thick scales to protect against bites.

Fur rarely has bright colors, mostly using a combination of white, gray, buff, brown and black. In many species, juveniles have very distinct, species-like fur that are not too dangerous to deceive prey.

Accipitridae have legendary vision abilities. Some eagles have up to 8 times better vision than humans. Large eyes with two foveae provide binocular vision to assess movement and distance. Hearing can be used to find prey hidden in vegetation. Accipitridae generally have a poor sense of smell.

Humpback whales (Megaptera novaeangliae) manufacture bubble-nets as tools to increase prey intake

NEWS - Humpback whales ( Megaptera novaeangliae ) create bubble net tools while foraging, consisting of internal tangential rings, and actively control the number of rings, their size, depth and horizontal spacing between the surrounding bubbles. These structural elements of the net increase prey intake sevenfold. Researchers have known that humpback whales create “bubble nets” for hunting, but the new report shows that the animals also manipulate them in a variety of ways to maximize catches. The behavior places humpbacks among the rare animals that make and use their own tools. “Many animals use tools to help them find food, but very few actually make or modify these tools themselves,” said Lars Bejder, director of the Marine Mammal Research Program (MMRP), University of Hawaii at Manoa. “Humpback whales in southeast Alaska create elaborate bubble nets to catch krill. They skillfully blow bubbles in patterns that form a web with internal rings. They actively control details such ...
