Heads up: Some or all of the identifications affected by
this split may have been replaced with identifications of Alcedo. This
happens when we can't automatically assign an identification to one of the
output taxa.
Review identifications of Alcedo euryzona 2612
Each of the two monotypic groups is recognized as a separate species: Blue-banded Kingfisher (Malaysian) Alcedo euryzona peninsulae becomes Malaysian Blue-banded Kingfisher Alcedo peninsulae, and Blue-banded Kingfisher (Javan) Alcedo euryzona euryzona becomes Javan Blue-banded Kingfisher Alcedo euryzona. The lack of clinality in the rather striking plumage differences (del Hoyo and Collar 2014; see also Eaton et al.) within the ranges of the two taxa, despite the fact that Sumatra and Java have been connected for most of the Pleistocene, is here taken as evidence of parapatry and thus species status.
Unintended disagreements occur when a parent (B) is
thinned by swapping a child (E) to another part of the
taxonomic tree, resulting in existing IDs of the parent being interpreted
as disagreements with existing IDs of the swapped child.
Identification
ID 2 of taxon E will be an unintended disagreement with ID 1 of taxon B after the taxon swap
If thinning a parent results in more than 10 unintended disagreements, you
should split the parent after swapping the child to replace existing IDs
of the parent (B) with IDs that don't disagree.
