Article Extract from Marcus Pollard at Clifton Finch Aviaries

This bird is a member of the mannikin family and, as such, should not be kept with nuns, yellow rumps or munias. I have always found them to be peaceful in a large aviary and, if trouble erupts, they are usually the victim rather than the aggressor. However, I am aware of people that have kept them in small aviaries and had them bully other finches. Will breed happily with just soaked/sprouted seed and green grasses.

They are fairly shy and will look for remote areas of the aviary to build their nests. No lining is usually used in their nests and this can present a problem if they attempt to breed in cooler months. In the wild they climb up seed heads to feed and if you hang green grass heads from the ceiling of your aviary in a loop of wire they will spend hours stripping these. They are long lived and I have a friend who has one that is 8 years old and still going strong!
