The speckled mousebird (Colius striatus) is a small, non-passerine bird that is native to eastern and southern Africa. They are found in a variety of habitats that include forest edges, thickets, gardens, orchards, strandveld, riverine woodland and tree plantations. Mousebirds are notable for their unusual metabolic patterns as they can enter a temporary form of hibernation, called torpor, to conserve energy on cold nights. During torpor their heart rate slows down, their body temperature decreases and their movements are greatly subdued. Mousebirds also expose their engorged stomachs to the sun after feeding to, presumably, aid digestion.
