Identificación

Blue-faced parrotfinch males are multi-shaded with colors ranging from light yellow-green to dark blue-green. On their forehead and face, there are deep blue feathers, and their tails are generally red to rusty red-brown. In terms of length, they are typically 13 cm (5.1 in) long.<p>On the other hand, the females are covered with a less vibrant blue and are slightly smaller and have more rounded heads.<p>Among the birds found in Queensland, there was no significant difference in plumage, bill shapes, or genetic composition. This is hypothesized to be caused by nomadic behaviors and the continued gene flow.

Distribución y hábitat

The blue-faced parrotfinches prefer rainforest edges and dense grasslands that have woody plants, and they prefer to roost in rainforests. They are widely distributed and found at various altitudes, ranging from sea-level on hot tropical islands to 800–3000 m in New Guinea. It is reported that the blue-faced parrotfinches engage in seasonal and nomadic movements, partly due to their cold-sensitiveness. In the winter, they migrate to the lowlands where there is excessive rainforest clearance.

Comportamiento

The blue-faced parrotfinches are inconspicuous and timid, retreating to grasslands for cover.<p>Blue-faced parrotfinches feed on grass and bamboo seeds, small insects, and figs. They primarily consume seeds of Brachiaria decumbens (Signal Grass), then the seeds of Lantana camara (West Indian Lantana), Panicum maximum (Guinea Grass), and A. patrei. They are adaptive enough to eat introduced food sources when they appear.<p>They forage primarily by perching (at an average height of 0.96 m) and less frequently by climbing and pecking. Due to this, there is not much strong competition between blue-faced parrotfinches and their sympatric species, who tend to forage primarily by climbing. Another reason for this lack of competition is that blue-faced parrotfinches partition food resources with other species by foraging at different preferred microhabitats.<p>Blue-faced parrotfinches are generally seen in patches, occasionally with 30 or more birds. The number of finches seen together increases in response to sufficient food resources.<p>The females usually lay an average of four eggs, with a maximum of eight. The average incubation time is 15 days, during which the female does most of the incubation and brooding. Meanwhile, the male is responsible for feeding the nestlings. The nestlings fledge around 21 days and continue to be fed by their parents for 10 to 20 days.
