Please give me a name

I'm not sure if this is a small African bird or not but it is one of the birds flying loose inside the Tropical Plant area in the Calgary Zoo's Conservatory. Can anyone tell me what bird this is?

"Pin-tailed Whydah male adult in breeding plumage has beautiful glossy black plumage on crown, upperparts and on very long tail feathers (about 20 cm). Wings are dark brown with conspicuous white marks. Cheeks, lower parts of face and underparts are white. Bill is bright crimson-red. Eyes are black. Legs and feet are dark.
Male and female in non breeding plumage have brown upperparts, strongly streaked with dark. Underparts are whitish with buff flanks. Buff face is boldly striped with dark. Female has brownish red bill. Male looses its long tail feathers during this period.
Immature resembles female, with rather uniform plumage and greyish bill." Taken, with thanks, from www.oiseaux.net.
