Recognized for its melodious flute-like song and distinctive "tick-tick-tick" call, it thrives in dense forest, primarily inhabiting canopy and understory amidst native mara trees.

Despite facing threats from introduces predators such as ship rats and invasive bird species, conservation efforts have been implemented to safeguard its population.

[3] This vocal and highly territorial bird keeps its insect foraging activities primarily under canopy or amidst undergrowth with minimal appearance in open areas.

[6] Despite demonstrating reduced fecundity, egg laying takes place year-round with heightened activity observed between August and January.

Nesting occurs in a fork of branches, opened like a cup and under a protective layer of leaves for rain and sunlight determent.

Exteriorly, a dash of white spider silk web is occasionally accompanied by small leaves, which is assumed to help aid in the concealment of their nest and structural integrity.

[2][5] Emerging as another significant ongoing threat, the high presence of introduced common Myna (Acridotheres tristis) and the Red vented Bulbul (Pyncnonotus cafer) have been spotted in territories experiencing nest failures and early fledgling deaths.

[2] After implementing comprehensive control measures by this program, including shooting, poisoning and trapping campaigns, the results showed a near absence of common Myna from Tahiti Monarch habitat, and Red-Vented Bulbul saw a decrease in population.

These efforts towards managing invasive birds were found to enhance the reproductive success of the Tahiti Monarch.
