The Portuguese, sailors found Guineas along African briars and introduced this fowl to Europe. This chicken-sized, noisy, skittish bird is difficult to handle but is lean meat source, rich in essential fatty acids. Wild helmeted and vulturine guineas have red eyes and a hackle of long, black and white striped feathers with "polka dots" covering a bright blue breast. Guineas are opportunistic feeders. The vulturine can live without drinking water deriving liquids from their foods.
