Editing Clark's grebe (section)

===Distribution===
Clark's grebes occur seasonally throughout the majority of Western America, with a distribution ranging as far south as Mexico, and reaching as far north as British Columbia and Saskatchewan. They avoid the cold and are only found in central USA and Canada during the summer breeding season. In the US and Canada breeding is done across a large portion of the west of these two countries, spanning from British Columbia to Texas, for which the grebes tend to favour larger bodies of water and congregate in large flocks.<ref name=Storer1992/>

Storer and Nuechterlein in 1992 dubiously claim the birds winter in Central America, as well as in Mexico and some regions of California.<ref name=Storer1992/> Out of almost 100,000 records of this taxon logged at the [[Global Biodiversity Information Facility]] there are zero records found south of northern [[Oaxaca]], Mexico.<ref name=GBIF>{{cite journal |url=https://www.gbif.org/species/2482032 |title=Aechmophorus clarkii (Lawrence, 1858) |author=<!--Not stated--> |date=2017 |website=GBIF Backbone Taxonomy.

The range of this bird in Mexico is distributed in two streaks southward; one from the California border along the Pacific coast throughout Baja California and across the [[Gulf of California|gulf]] along the coast to southern [[Sonora]], the other a higher altitude, inland distribution running down from the [[Big Bend (Texas)|Big Bend]] region behind the Texas border down the mountains of central Mexico, with the highest concentration in population in the south from [[Jalisco]] to [[Puebla]] and northern Oaxaca, where the distribution abruptly ceases. These two distributional areas representing where grebes have ever been seen only meet each other in the very north of Mexico in a strip along the USA border, to the south they do not come together and are separated by a very large distance. It is completely absent from the Atlantic coast.<ref name=GBIF/>
