Taxonomic note
Corythornis cristatus, C. nais and C. thomensis (del Hoyo and Collar 2014) were previously placed in the genus Alcedo and lumped as A. cristata following Melo and Fuchs (2008). Prior to that, all three taxa had been split as A. cristata, A. thomensis and A. nais following Sibley and Monroe (1990, 1993).
