Welcome to the SPI Birding, Nature Center & Alligator Sanctuary

We are the Rio Grande Valley's premier destination for birdwatching. Our unique location on South Padre Island is the perfect place to observe the birds, butterflies and natural wildlife in coastal South Texas.  Visit us on South Padre Island, walk the bayfront boardwalks, take a birding tour and explore the natural life of the Rio Grande Valley.

Our Mission

The mission of the South Padre Island Birding & Nature Center is to educate the public about birds of South Padre Island and its environs: the flora, fauna and the natural environment of South Padre Island, the Laguna Madre Coastal area, with an emphasis on conservation and environmental awareness.

We are a non-profit organization created by the Town of South Padre Island’s Economic Development Corporation in response to the researched desires of our residents and visitors.
