inca collarejo

Un colibrí de tamaño mediano-grande de los bosques montanos andinos de Colombia a Bolivia, los incas collarejo tienen un plumaje negro y blanco llamativo con una ancha banda pectoral blanca y manchas caudales blancas distintivas visibles en vuelo. Habita bosques y bordes forestales a altitudes de 1.700-3.200 metros, se alimenta en diversas plantas con flor y es un importante polinizador de arbustos y árboles andinos de grandes flores. Sus contrastantes manchas caudales blancas centellean prominentemente durante el vuelo en suspensión, ayudando al reconocimiento de la especie.

Common Water Rat

<em>Hydromys chrysogaster</em>, commonly known as the common water rat or rakali, is a semi-aquatic rodent in the family Muridae, native to Australia and New Guinea. It is classified as Least Concern by the IUCN, reflecting its relatively stable population across a broad range of freshwater and estuarine habitats on the Australian continent and associated islands. The species typically inhabits the banks of rivers, lakes, wetlands, and estuaries, where it constructs burrows in streambanks. It is highly adapted for an aquatic lifestyle, with partially webbed hind feet, a flattened head, and a dense waterproof coat. <em>Hydromys chrysogaster</em> is a carnivore, typically feeding on fish, crustaceans, mussels, frogs, and aquatic invertebrates, which it often carries to elevated feeding platforms to consume. The species is nocturnal and crepuscular, most active during early morning and evening hours near the water's edge. Biological traits including average lifespan, body length, and weight remain poorly documented in standardized databases, though adults are generally robust for a rodent, reportedly reaching body lengths of 20–35 cm excluding the tail. Geographic range details for this particular record remain incompletely documented in available data sources. Ecologically, the common water rat is an important apex predator in small-scale freshwater food webs and serves as an indicator species for wetland health in Australian riparian systems.
