This species is judged to be Vulnerable on the basis of an estimated small population which is likely to be declining through habitat loss and degradation. However, researching its population size, tolerance of habitat changes and dispersal between subpopulations may lead to reclassification.

Alcedo websteri (Hartert, 1898)
22 cm. Medium-sized, river kingfisher. Greenish-blue upperparts, extending as slight partial collar onto pale buffy underparts. Black bare parts. Similar spp. Three similar but smaller species: Common Kingfisher A. atthis is greener above, more orange below and lacks the slight collar, Variable Kingfisher Ceyx lepidus is more purple above, brighter orange below and often with red on the bill, Little Kingfisher C. pusillus is purple-blue above and very small. Voice Louder, stronger and less sibilant than A. atthis. Hints Search medium-sized rainforest streams. Perhaps more common on small islands.
