San José Island is a small, uninhabited landmass situated in the Gulf of Mexico, off the Texas coast. The island is renowned for its pristine beaches, crystal-clear waters, and bountiful wildlife.
Daunting cliffs, lush vegetation, and quiet lagoons cover most of its pristine acreage. One of the main attractions for bird enthusiasts is the island’s avian diversity.
Over 240 bird species have been recorded on San José Island, making it one of Texas’s most prominent bird-watching destinations.
The island is considered a vital stopover point for migratory birds, providing an essential habitat for their survival.
This article introduces the avifauna of San José Island, highlighting different bird species, their habits, and how they fit into the ecosystem.
17 Birds in San José Island
San José Island is located off the coast of Baja California in Mexico. The island is known for its diverse birdlife and is an important habitat for several species of seabirds and shorebirds. Some of the bird species that can be found on San José Island include:
1. Rock Dove
Rock dove, also known as Rock Pigeon or Common Pigeon, is a member of the bird family Columbidae.
It is considered to be an important creature worldwide due to its domestication by humans centuries ago, resulting in the modern-day Domestic pigeon, which descends from this species.
Its population has increased over time because some domestic pigeons have escaped captivity and joined wild populations.
The rock dove can most easily be identified by its prominent blue-grey feathers, darker bars on the wings and tail, and two black bands on each wing.
They are typically found in large flocks near cliffs or buildings but may also inhabit rural habitats such as open fields and meadows if there’s enough food available for them nearby.
Although they don’t migrate far distances like other birds, their numbers increase significantly during winter months.
When more food sources become available, they won’t need to travel too far away from their home base for nourishment.

2. Hummingbirds
Hummingbirds are tiny birds found throughout the Americas, from Alaska to Tierra del Fuego. Most species measure between 3-5 inches in length and weigh less than an ounce.
The smallest hummingbird is only 2 inches long. Hummingbirds have a unique ability to hover by rapidly flapping their wings up to 80 times per second.
They feed on nectar and insects, with some species even able to drink sap or eat pollen directly off flowers.
Their vibrant colours make them instantly recognizable as they dart through gardens searching for food and mates.
Hummingbirds truly bring joy into our lives as they remind us that nature’s beauty can be seen around every corner if we take the time to look for it.

10. Roseate Spoonbill
The Roseate Spoonbill is a beautiful and majestic bird in North and South America.
It belongs to the ibis family, Threskiornithidae, and its vibrant pink colour comes from canthaxanthin pigment derived from their diet of crustaceans like shrimp.
