And that extension makes practical sense if we are to stick with this as a definition, as we often use vernacular names for groups of subspecies rather than names for a single subspecies (e.g. Myrtle Warbler x Audobon's Warbler intergrades where Myrtle can, in theory if not in practice, be either coronata or hooveri and Audubon's can be auduboni, nigrifons or goldmani). I still feel that that definition is lacking, as it depends on the current and sometimes almost arbitrary taxonomic treatment rather than the reality of what is actually going on with the birds.Dave Appletonhttps://www.blogger.com/profile/15077880196249359409noreply@blogger.comtag:blogger.com,1999:blog-8553998527275861247.post-35299689630856606002016-01-10T23:50:07.259+00:002016-01-10T23:50:07.259+00:00I, too, realized I didn't know the difference ...I, too, realized I didn't know the difference between a hybrid and an intergrade and went googling. This is how I found your article and blog. I also found an eBird post about its updated taxonomy as of August 15, 2015. Here are the definitions they give:<br />Hybrid: Hybrid between two species, e.g., American Black Duck x Mallard (hybrid)<br />Intergrade: Hybrid between two ISSF (subspecies or subspecies groups), e.g., Mallard (Mexican intergrade)<br />ISSF or Identifiable Sub-specific Group: Identifiable subspecies or group of subspecies, e.g., Mallard (Mexican)<br />Here is the URL for the post: http://help.ebird.org/customer/portal/articles/1006825-the-ebird-taxonomyCharleshttps://www.blogger.com/profile/10869082131080822158noreply@blogger.com
