White-throated treecreeper
The white-throated treecreeper is a unique bird species found exclusively in the rainforests of Australia and New Guinea. It typically inhabits eucalyptic forests and is often observed alongside the red-browed treecreeper. Adults measure between 5 to 7.5 inches (12 to 19 centimeters) in length, weighing up to 1.5 ounces (20 to 40 grams). Their plumage is characterized by a brown to black coloration on the upper body, with striped or reddish-brown underparts; females are distinguished by an orange cheek spot. The bird is an adept climber, equipped with long toes and sharp claws that allow it to navigate its arboreal habitat effectively.
Dietarily, the white-throated treecreeper primarily consumes insects, especially ants, but occasionally feeds on nectar. During breeding season, these birds form pairs, with non-breeding individuals often assisting the female in caring for the young. The female lays two to three white eggs speckled with brown in a shallow nest within a tree, which requires about three weeks of incubation. After hatching, the chicks remain in the nest for 25 to 26 days, during which they are nurtured and fed. Their vocalizations consist of a variety of sounds, including piping notes, trills, and rattles, contributing to their distinct presence in the rainforest ecosystem.

White-throated treecreeper
The white-throated treecreeper is the only treecreeper which lives in the rainforests of Australia and New Guinea. In eucalyptic forests, or forests with many eucalyptus trees, it is often seen living closely with another species, the red-browed treecreeper.

The adult white-throated treecreeper grows to a length of 5 to 7 1/2 inches (12 to 19 centimeters) and reaches a weight of up to 1 1/2 ounces (20 to 40 grams). The feathering, or plumage, of the white-throated treecreeper is brown to black above and striped or rufous (reddish-brown) underneath. The female has an orange spot on her cheek. The white-throated treecreeper has long toes with sharp claws that turn downward. The treecreeper is an excellent climber due to its long toes and sharp, downward curving claws. The bill of the white-throated treecreeper is curved downward as well. This helps the bird feed on insects hiding in tiny cracks and crevices.
The white-throated treecreeper is the only species of treecreepers which may be found in the rainforests. This fact has lead many to believe that the bird shares different ancestors than other members of its family.
The white-throated treecreeper lives on a diet of insects, ants in particular. They will also sometimes eat nectar.
The white-throated treecreeper, while remaining solitary, or alone, during the nonbreedng season, lives in pairs during the breeding season. Those birds within the group that do not breed help the breeding female with her young.
After mating, the female white-throated treecreeper lays two to three eggs. The eggs are white in color with small brown dots. These eggs are laid in a nest, consisting of a cup-like hollow, or shallow hole, in a tree or on a branch. The incubation period lasts for about three weeks. During this time, the female sits on the eggs, the warmth from her body providing them with the heat they need to develop. During this period, the female may receive help from the male and other helpers. After the eggs hatch, the newborn young, called hatchlings, remain in the nest for 25 to 26 days. This nestling period is important for the young as it is during this time that they receive the nourishment necessary for growth.
The voice of the white-throated treecreeper is described as loud piping notes, trills, chatters, harsh grates, and rattles.
