The BUBO Listing Ontario list is a subset of the full Canada list, initially based on Avibase, and will be kept up to date following Clements taxonomy.

An official Ontario list is maintained by Ontario Field Ornithologists, although is not as up to date with recent sightings or taxonomy.

Want to be an editor for this checklist?

First select authority to copy existing species from, then type species name, or enter a new species directly.

Species name is defaulted from the previous species row and should of course be overwritten!.

Genus is defaulted from the previous species row but may need overwriting; specific needs to be entered in either case.

NB: Species name for the old taxon should be updated to differentiate it from the split taxa using a '/' or '[group]', e.g. Species A/Species B or Species A [group].

NB: Scientific should also be updated similarly, e.g. Genus specific A/specific B or Genus specific A [group].

NB: Notes only allow up to 255 characters, but there is no enforcement of this. Anything longer will be truncated without warning.

NB: Species name for the old taxon should be updated to differentiate it from the split taxa using '[lumped]', e.g. Species A [lumped].

NB: Scientific should also be updated, using '[lumped]' or brackets for the old specific name, e.g. Genus specific [lumped] or Genus [specific] subspecific.

NB: Notes only allow up to 255 characters, but there is no enforcement of this. Anything longer will be truncated without warning.
