Heads up: Some or all of the identifications affected by
this split may have been replaced with identifications of Melanitta. This
happens when we can't automatically assign an identification to one of the
output taxa.
Review identifications of Melanitta fusca 7032
Clements, J. F., T. S. Schulenberg, M. J. Iliff, D. Roberson, T. A. Fredericks, B. L. Sullivan, and C. L. Wood. 2018. The eBird/Clements checklist of birds of the world: v2018. Downloaded from http://www.birds.cornell.edu/clementschecklist/download/ (Link)
By the way, this is getting really weird now, with both M. fusca deglandi and M. deglandi existing, as well as most North American and Asian records still being M. fusca.
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.
Any reason not to commit this?
