Esmeralda Coliazul

Un pequeño colibrí con apariencia de joya, nombrado por el brillante iridiscente azul-verde de sus plumas caudales; los machos de esmeralda coliazul muestran un plumaje verde brillante con una cola bifurcada azul-verde profunda en contraste. Se encuentran en los bordes de bosques tropicales de tierras bajas, sabanas y jardines desde Venezuela y Colombia al este hasta Trinidad y al sur hasta Bolivia y Brasil. Son comunes en hábitats perturbados y secundarios, lo que los hace relativamente resilientes a la modificación del hábitat.

Cinnamon antechinus

The cinnamon antechinus (Antechinus leo) is a small marsupial in the family Dasyuridae, endemic to northeastern Queensland, Australia, particularly the Cape York Peninsula. It inhabits tropical and subtropical rainforest and forest margins at low elevations, sheltering in tree hollows, dense vine tangles, and fallen logs. Like all antechinuses, it is a specialist insectivore, consuming beetles, cockroaches, moths, and other invertebrates, and occasionally small lizards. The cinnamon antechinus is named for its rich cinnamon-brown dorsal fur. A remarkable feature shared by all antechinus species is semelparous reproduction: males undergo a catastrophic physiological decline and die shortly after a brief, intense mating season in winter, leaving only the pregnant females to carry the population into the next generation. This extreme reproductive strategy results in completely male-free populations for most of the year. The species is classified as Least Concern by the IUCN, with populations within Cape York's relatively intact tropical forest. However, like all antechinuses, it faces threats from feral predators (cats and foxes), habitat degradation, and altered fire regimes. Climate change poses a long-term risk by shrinking the cool, moist forest habitats this species depends on. Genetic studies of Australian antechinuses have revealed considerable cryptic diversity.
