A principal difference is the sheer magnitude of breeding waterbirds in the Salton Sink, where many species have their largest population in the interior Southwest (Patten and McCaskie 2003). The relative compositions of the avifaunas differ, yet both regions share many breeding species. Notable absentees from the Colorado River region are the Cattle Egret, which nests in the Salton Sink in the tens of thousands, and the White-faced Ibis, a regular but less numerous breeder. Chief among breeding waterbirds in the Salton Sink are the Double-crested Cormorant and various species of herons and egrets, each with thousands of pairs nesting annually.

A scarce but annual species is the Shorteared Owl, a small population of which winters in the Imperial Valley. All three valleys support substantial populations of the American Kestrel and the Loggerhead Shrike, with both species being fairly common to common breeders (and common winter visitors) throughout the agricultural portions of the Salton Sink.
