Cormorants, Shags
- Phalacrocoracidae
Bird family - Until recently, the genera of cormorants and the distinctions between "shags" and "cormorants" have remained mostly unresolved due to conflicts among studies and missing taxa (Siegel-Causey 1988; Kennedy et al. 2000; Christidis & Boles 2008). We follow the comprehensive phylogenetic studies of Kennedy & Spencer (2014) and Kennedy et al. (2019) in resequencing this family. Generic revisions were accepted for the North American species by NACC (Chesser et al. 2021) but narrowly declined by SACC (Proposal 648).
