Among the congeners of the Beef-eater may be placed the 

 CoLius (Briss. and Linn.), which, like that bird, is an inhabitant 

 of Africa. They are small, about the size and shape of the 

 Yellow-hammer, and have a tuft on the head. They live in 

 flocks of from twelve to twenty, which nest in common, and 

 feed on fruit and young birds. According to Levaillant, they

 strange to say, even sleep in this peculiar position, pressing one 

 against the other. Their flesh is said to be very delicate.

 each other in contrary directions, the terminations being hooked,

 of their food. They are sometimes found near orchards, feeding
