Actenoides bougainvillei and A. excelsus (del Hoyo and Collar 2014) were previously lumped as A. bougainvillei following Sibley and Monroe (1990, 1993).
||27 cm. Beautiful but very cryptic forest kingfisher. Very few sightings or specimens. Largely rufous with blue wings, rump and tail with distinctive blue moustachial and eye-stripes and red bill. Similar spp. A. excelsus (formerly included with this species) has black rather than blue moustacial and postocular stripes and a much darker greenish black mantle. Sacred Kingfisher Todiramphus sancta has paler buff underparts and collar. Variable Kingfisher Ceyx lepidus is much smaller. Voice Calls before dawn and after dusk: a loud, ringing series of ko-ko-ko... notes.

This spectacular species is judged to be Endangered on the basis of a very small estimated population which is suspected to be declining. However, further research may reveal it to be more common and not declining.
|Previously published Red List assessments:|
|Population:||The population is estimated to number 250-999 mature individuals based on an assessment of known records, descriptions of abundance and range size. This is consistent with recorded population density estimates for congeners or close relatives with a similar body size, and the fact that only a proportion of the estimated Extent of Occurrence is likely to be occupied. This estimate is equivalent to 375-1,499 individuals in total, rounded here to 350-1,500 individuals.|
Trend Justification: There are no data on population trends; however, the species is suspected to be declining at a slow to moderate rate, owing to predation by introduced rats and cats, and possibly by habitat degradation.
