Field Identification

12 cm. Small, delicate, greyish-and-buff monarch-flycatcher. Has cinnamon-buff or white eyering and loral area, white supraloral area; soft slaty-grey crown and upperparts, rectrices broadly tipped buff; dull pinkish-cinnamon below, paler on throat; iris dark; bill and legs dark grey. Sexes alike. Juvenile is similar to adult.

Systematics History

Recent phylogenetic study (1) suggests this species may merit its own genus; study needed. Monotypic.

Subspecies

Monotypic.

Distribution

Fiji: Ogea Levu, Ogea Driki and Dakuiyanuya (S Lau Is).

Habitat

Limestone forest, often on forest edge; avoids village and agricultural lands.

Movement

Sedentary.

Diet and Foraging

Insects. Often associated with mixed flocks with Myiagra vanikorensis, Golden Whistler (Pachycephala pectoralis) and sometimes Clytorhynchus vitiensis. Forages at all heights, from ground level to canopy; works vine tangles. Primarily a foliage-gleaner. Also makes aerial sallies after flying insects; sometimes works up trunk and large branches.

Sounds and Vocal Behavior

Vocal. Usual call a mild but far-carrying “tsic”, louder and more frequent when agitated; also a frequent short “tsic” series followed by upslurred whistle. All calls similar in character to those of M. lessoni.

Breeding

Fledgling observed in Jul. No other information.

Not globally threatened. Currently considered Near Threatened. Restricted-range species: present in Fiji EBA. Has extremely small range (18 km²), but population healthy and no evidence of decline at present. Estimated 2000 individuals in 1986; in 2004, five individuals seen in four hours, with one sighting of a pair, and described as uncommon and inconspicuous. Surveys of Ogea Levu and Ogea Driki in July 2011 recorded 49 individuals, equivalent to a density of 192·2 birds / km² BirdLife International (2016) Species factsheet: Mayrornis versicolor. Downloaded from http://www.birdlife.org on 14/04/2016. , which is almost double the 106·8 birds / km² encountered in 1986 (2), suggesting that the population is stable or increasing; crude extrapolation from these puts the population at 3204 birds, or 1300–2000 mature individuals BirdLife International (2016) Species factsheet: Mayrornis versicolor. Downloaded from http://www.birdlife.org on 14/04/2016. . Removal of old-growth forest may lead to increase in numbers, as it appears to prefer secondary habitat. Feral cats (Felis domesticus) are potential predators, being quite common in forest. Interbreeding with M. lessoni does not appear to be significant threat. A possible translocation site, Vulaga I, has been identified (M. lessoni does not occur there) in case a critical situation arises on Ogea Levu. Protected by Fijian law. Suggestions made to raise public awareness of the species by making it the figurehead for conservation on Ogea Levu. Imposition of stringent quarantine measures needed in order to prevent establishment of exotic predators. Formerly considered Vulnerable, new data on population size and trends triggered downlisting to Near Threatened in 2015.
