Does the brown kiwi bird have prickly fur?
No. The kiwi is a bird. It has soft, shaggy feathers.
Yes kiwi have feathers. However, their feathers lack the "hook and barb" system of flighted birds (which links all the "strands" of the feather together to keep them stiff and help with flight) so it looks more like fur (but isn't!). Patting a kiwi feels more like patting matted cat fur, the feathers are soft but the main shaft of the feather is a bit prickly feeling.
Kiwi have several unusual characteristics. They are the only birds with nostrils at the very tip of their beak. Their eggs are the largest in proportion to their body size, being about six times the size of that of another bird of the same size. The eggs are about 120mm long and 80mm in diameter. Kiwi have very soft, wispy feathers which almost resemble fur.
