Endemic birds, animals and plants are those which have evolved into a distinct form which is restricted in its distribution to a particular locality. Genetic isolation, such as that found on islands, is often a factor which contributes to a high degree of endemism.

Eleven of the 60 species of land birds that have nested on the park islands are represented by endemic species or subspecies – forms that are found on the islands and nowhere else. A few of these endemics are found on only one of the Park islands:

Others are found on two or more of the islands: non-migratory

The Island Scrub-Jay, which is confined today to Santa Cruz Island, is the most distinct and only endemic species of bird found on the Channel Islands. Of the island endemics found on the park islands, two populations on Santa Barbara Island (San Clemente House Finch and Santa Barbara Island Song Sparrow) have been extirpated during the past century.

On Santa Catalina Island Catalina the California quail and Bewick's wren are endemic.
