Chatham Bellbird

The Chatham Bellbird (Anthornis melanocephala) is a species in the genus Anthornis. It is currently classified as Extinct on the IUCN Red List. Typically found in various aerial, terrestrial, and aquatic environments.

Common Leaf-litter Frog

The Common Leaf-litter Frog (<em>Craugastor loki</em>) is a direct-developing frog in the family Craugastoridae, classified as Least Concern on the IUCN Red List. It is native to Mexico, where it typically inhabits freshwater habitats, moist forests, and wetlands in tropical and subtropical lowland and montane regions. As a member of the genus Craugastor, this species undergoes direct development, with eggs hatching as miniature froglets rather than passing through a free-living aquatic tadpole stage. This reproductive strategy reduces dependence on standing water and allows the species to colonize a variety of moist terrestrial microhabitats, including forest floor leaf litter, mossy logs, and stream banks. The Common Leaf-litter Frog is cryptically colored, blending into its leaf litter surroundings for camouflage against predators. Its Least Concern status reflects relatively stable populations within its Mexican range. Biological traits of this species remain poorly documented in the scientific literature.
