The current issue of Ibis describes a
new species of phylloscopus warbler
found in Vietnam and Laos. Limestone Leaf Warbler Phylloscopus calciatilis was previously considered a possible subspecies of Sulphur-breasted Warbler Phylloscopus ricketti. We have added this species as a provisional species to the Clements World list and to the OBC Oriental region list on BUBO Listing. You can see some
photos of it at the OBC Image Database
and read
details of it's discovery from the BBC
