Taxonomic note
Phylloscopus presbytes has been split into Timor Leaf-warbler P. presbytes and Rote Leaf-warbler P. rotiensis after Ng et al. (2018).

The previously undescribed taxon, in comparison with P. presbytes, differs by its; greater bill length, possibly related to a bark-gleaning habit unusual in leaf-warblers (16.3 [n=1] vs 13.4 [n=2] (allow 3); much stronger pale yellow median crown-stripe (2); wholly yellow-orange vs mostly dark lower mandible (1); richer yellow underparts, supercilium and ear-coverts (2); brighter olive-brown upperparts (ns[1]).

The proposed treatment of P. presbytes floresianus in Ng et al. (2018), called Seicercus floris in Eaton et al. (2016) is not accepted: the latter suggested 'differences in plumage and voice', but no vocal differences were found by Ng et al. (2018), the plumage differences are not quantified, and the taxon was not included in genetic sampling. Consequently the treatment of the taxon as a subspecies of P. presbytes is upheld.

Population justification: The global population size has not been quantified, but the species is described as common to very common on Flores and common and widespread on Timor (del Hoyo et al. 2006).

Trend justification: The population is suspected to be stable in the absence of evidence for any declines or substantial threats.
