Cloud Forest Stream Frog

Cloud forest stream frogs are hylid frogs in the genus Ptychohyla (family Hylidae) native to the montane cloud forests of Middle America, from southern Mexico through Central America. These medium-sized treefrogs inhabit rocky montane streams and waterfalls within dense cloud forest, where they breed in fast-flowing water and larvae develop attached to rocks using specialized oral suckers adapted to resist strong currents. Adults are typically greenish-brown with darker dorsal patterning providing camouflage against mossy stream margins and vegetation. They are nocturnal, foraging for insects and other invertebrates along stream courses and in adjacent cloud forest undergrowth. Several Ptychohyla species are restricted to single mountain ranges or small highland areas, making them highly vulnerable to habitat loss. The dual threat of chytridiomycosis caused by Batrachochytrium dendrobatidis and cloud forest loss through agricultural conversion has severely impacted populations of several Ptychohyla species, with multiple species now listed as Critically Endangered or potentially extinct following the wave of chytrid-associated amphibian population collapses that swept through Central American highland amphibian communities in the late 20th century.

Gray/Purple Heron

A large, elegant wading bird reaching up to 1 meter in height, gray herons inhabit wetlands, rivers, lakes, and coastal areas across Europe, Asia, and Africa. Patient, solitary hunters, they stand motionless for long periods before striking fish, frogs, and small mammals with lightning-fast dagger bill strikes. They nest colonially in tall trees in rookeries called heronries, sometimes shared with other colonial waterbirds. Widely distributed and of Least Concern globally.
