Recent Additions to the Avifauna of the Salton Sink

In spite of many environmental changes that disfavor birds, from 2002 through 2024 the list of bird species recorded within the Salton Sink in southeastern California and adjacent Baja California increased from 413 to 459 species. Four additions are the result of taxonomic changes in which one species was split into two, but the others are the addition of 40 native and two non-native species, the result of continued coverage of the Salton Sink by professional biologists and knowledgeable birders.
