Baja California, Mexico, is home to several endemic bird species, meaning they are found nowhere else in the world. The exact number of endemic bird species in Baja California can vary slightly depending on taxonomic classification and recent discoveries. However, as of my last update in January 2022, Baja California is estimated to have around 30 to 35 endemic bird species.

Some of the notable endemic bird species of Baja California include:

1. Xantus’s Hummingbird (Basilinna xantusii): This small hummingbird is found only in Baja California Sur and a small part of Baja California.
2. Belding’s Yellowthroat (Geothlypis beldingi): This striking yellowthroat is endemic to the wetlands of southern Baja California.
3. San Lucas Robin (Turdus migratorius confinis): Endemic to the southern tip of Baja California, this robin is a subspecies of the American Robin.
4. Cape Pygmy Owl (Glaucidium hoskinsii): This small owl is found only in the southern part of the Baja California Peninsula.
5. Cape Sparrow (Passer melanurus): Also known as the Baja California Sparrow, this species is endemic to the southern tip of the peninsula.

These are just a few examples of the endemic bird species found in Baja California. The region’s diverse habitats, including deserts, mountains, and coastal areas, support a unique array of birdlife, making it an important area for birdwatching and conservation.
