The prevailing colour of this beautiful species is a brilliant light blue, shading towards the top of the head into resplendent blueish green; the upper part of the back, wings, and tail, as well as a stripe surrounding the eye, are black, and the inner margins of the wings yellow. The eye is greyish brown, the beak and foot bright orange-red. The plumage of the female is siskin-green on the upper parts of the body, and pale green beneath; the throat is whitish. The length of this species is four inches and two-thirds, the wing measures two inches and a quarter, and the tail one inch and a quarter.

These beautiful birds are met with throughout the greater part of South America, and are especially numerous about Espirito Santo. The Prince von Wied found them in large numbers inhabiting the forests near the coast, and tells us, that except during the breeding season, they live in small parties of six or eight, which disport themselves among the topmost branches of the trees, frequently associating with Tangaras, and such other of the feathered inhabitants of their leafy retreats as are about their own size. Fruit, seeds, and insects constitute their principal means of subsistence, and in pursuit of these they display an agility and dexterity fully equalling that of our own Titmouse. The voice of the Sai is only capable of producing a gentle twitter. Schomburghk mentions that large numbers of a very similar species are destroyed by the natives, who employ the gay and glossy feathers as personal ornaments.
The PITPITS (_Certhiola_) have a high slender beak, which curves gently towards its sharp tip; their wings are long, their tail short, and their tongue divided into two parts, each of which terminates in a brush of thread-like fibres.
THE BANANA QUIT, OR BLACK AND YELLOW CREEPER.
The BANANA QUIT, or BLACK AND YELLOW CREEPER (_Certhiola flaveola_), is blackish brown on the upper parts of the body, and of a beautiful bright yellow on the under side and rump; a line that passes above the eyes, the anterior borders of the primary quills, the tips of the tail, and its two outer feathers are white; the throat is ash-grey, the eye greyish brown, the back is black, and the foot brown. The female is blackish olive on the back, and pale yellow on the under side; in other respects her plumage resembles that of her mate. The length of this species is three inches and five-sixths; the wing measures two inches and one-sixth, and the tail one inch.
