Rouen duck Rouen duckling is identical to the Mallard duckling in terms of plumage coloring. In North America, two distinct types are bred: the common, or production-bred, variety that is larger than a Mallard but has a typical duck conformation, and the much larger and squarer standard-bred variety. The production variety normally weighs 6–8 lbs (2.7–3.6 kg) while the standard-bred weighs 9–12 lb (4.1–5.4 kg). Rouen ducklings can be distinguished from wild mallard ducklings by the presence of a second stripe which runs across their face, just under their eye, whereas mallard ducklings have only one stripe which runs across their eye.
Khaki bromeliad frog yellow chromatophores. The vocal sac is grey to black. The male call is a two-note call, the second note being higher than the first one, and is preceded by about 4–5 warm-up notes. Calling sites are in trees, above the ground, probably also higher. Natural habitats of "Eleutherodactylus fowleri" are high-elevation mesic forests. It is an arboreal species occurring in bromeliads in tall trees, using them for both hiding and breeding. It is threatened by habitat loss, particularly from felling large trees. It occurs in the Sierra de Bahoruco National Park in the Dominican Republic. Khaki bromeliad frog The khaki
