The skeleton of "C. liberiensis" is more gracile than that of the common hippopotamus, meaning their bones are proportionally thinner. The common hippo's spine is parallel with the ground; the pygmy hippo's back slopes forward, a likely adaptation to pass
Cloud-forest pygmy owl cloud-forest pygmy owl populations. Unfortunately, the cloud-forest pygmy owl benefits little from existing conservation units, with no records from large protected areas despite the existence of apparently suitable habitat. Cloud-forest pygmy owl The cloud-forest pygmy owl ("Glaucidium nubicola") is a short, muscular, small-sized species of owl found throughout the Andes of western Colombia and north-western Ecuador, being confined to cloud forests between 900–2000 m a.s.l. Below this altitudinal range the Central American pygmy owl ("Glaucidium griseiceps") occurs; above it, the Andean pygmy owl ("Glaucidium jardinii") occurs. Its epithet "nubicola" is Latin for “cloud-inhabiting”, because this species is restricted to very
