A Tropical Parula (Setophaga pitiayumi) photographed and audio-recorded in Big Dalton Canyon, Los Angeles County, 12–14 May 2024 established a second record of the species for California and the first in spring or summer. Another sighting at the Switzer Picnic Area, 30.5 km to west but also within the San Gabriel Mountains, 4 July–26 September 2024, likely represented the same individual. Only the two northernmost subspecies of the Tropical Parula are partially migratory, S. p. nigrilora, which nests in eastern Mexico and north into south Texas, and S. p. pulchra, which is found along the Sierra Madre Occidental. The broad white wingbars, deep orange flanks, and pattern of the song identify the bird in the San Gabriel Mountains as pulchra. Narrower wingbars, paler flanks, and pattern of the song identify California’s previous Tropical Parula, at Huntington Beach, Orange Co., 5 January–14 February 2018, as nigrilora. Despite its relatively sedentary nature, the Tropical Parula has been detected as a vagrant in Colorado, Kansas, northern Texas, New Mexico, Arizona, and now at least twice in California.
