Justification of Red List category

This species has a very large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km² combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). For these reasons the species is evaluated as Least Concern.

Population justification
The global population size has not been quantified, but the species is described as common (del Hoyo et al. 2006).

Trend justification
This species is suspected to be declining in line with ongoing habitat loss. Data from Global Forest Watch (2021) suggests that the rate of decline is likely to be <20% over 10 years.

Crossleyia xanthophrys, a distinctive babbler in its own genus, is a fairly common resident throughout eastern Madagascar, from Tsaratanana in the north to Andohahela in the south (Morris and Hawkins 1998).

The species inhabits montane rainforest at 800-2,300 m (Hawkins and Sartain 2013). It is mainly terrestrial, foraging for insects in the leaf-litter and among herbs (Langrand 1990, Evans et al. 1992), but in evenings will climb in vegetation presumably to roost (Hawkins and Sartain 2013). It is usually found in pairs, or as family groups in mixed-species flocks with other small insectivores (Langrand 1990; Evans et al. 1992; Morris and Hawkins 1998). It breeds in September-December, with juveniles observed in November-January (del Hoyo et al. 2006). The nest in which three eggs are laid, is a deep cup of interwoven grasses or bamboo leaves and moss, on a bulky base of leaf litter or in a dense liana tangle (del Hoyo et al. 2006).

The species is potentially threatened by the significant reduction or fragmentation of its habitat (del Hoyo et al. 2006). The activities that are expected tp drive deforestation and forest modification, are the encroachment of small-holder cultivation and livestock farming and both small- and large-scale logging for timber.

Conservation Actions Underway
It occurs in most protected areas within its range and is common in Tsaratanana Strict Nature Reserve, and Marojejy, Mantadia, Ranomafana, Andringitra and Andohahela National Parks (del Hoyo et al. 2006).

Conservation Actions Proposed
Carry out surveys to obtain a total population estimate. Monitor population trends through regular surveys. Monitor potential threats to the species's habitat. Increase the area of suitable habitat that has protected status.

A small terrestrial babbler. Dark olive green above, with a vivid yellow supercilium contrasting with a black eyestripe. Throat and upper belly yellow, bill pale pink with dark culmen. Walks on the ground with a rolling gait, often in areas of dense understorey. Similar spp. Immediately distingushed from Malagasy greenbuls, Crossley's Babbler Mystacornis crossleyi and White-throated Oxylabes Oxylabes madagascariensis by the very obvious yellow supercilium. Hints Limited to the understorey of dense montane forest from about 900 m to the limit of tree cover. Often first detected by the call, a penetrating "tsirp", coming from dense understorey vegetation.
