Here's a site that has much love for the little Java Sparrow (aka Java Finch or Java Rice Bird), a very popular cagebird. It is listed on the IUCN Red List as a vulnerable species (threatened) and is likely headed for endangered status if things don't improve for them. I've provided a pic below so you'll know which ones to click to get the various patterns.
