Bee-eaters are known for several distinctive characteristics:
Bright Plumage: They exhibit vibrant colors such as green, blue, yellow, red, and purple. Many species have brightly colored, elongated central tail feathers.
Bill: Bee-eaters possess long, slender, slightly downturned, and sharply pointed bills, ideal for catching insects.
Size and Body: These birds are medium-sized, usually ranging from 7 to 12 inches in length. They have slender bodies, large heads, short necks, and short legs.
Wings: They have medium to long wings, which can be pointed or rounded. Those with longer wings tend to be more migratory.
Diet: As their name suggests, bee-eaters primarily feed on bees, wasps, and other insects.
Social Behavior: They tend to have complex social relationships, especially in species with sedentary populations.
Distribution: Most species are found in Africa and Asia, with some also residing in southern Europe, Australia, and New Guinea.
