Hummingbird Rescue Center in Chula Vista is a 501(c)(3) nonprofit wildlife sanctuary on Fig Avenue dedicated to rehabilitating orphaned and injured hummingbirds across San Diego County. Injured wildlife intake in the South Bay often involves coordination with municipal facilities, and Chula Vista Animal Services directs hummingbird-specific cases to the center's federally permitted rehabilitation program. Hummingbirds are protected under the Migratory Bird Treaty Act, and all rehabilitation must be performed by U.S. Fish & Wildlife Service-permitted handlers holding valid federal and California state rehabilitation licenses. Veterinary assessment of fractures, window-strike trauma, and nestling dehydration draws on avian-medicine protocols also practiced at South Bay Veterinary Hospital for broader wildlife triage in the 91910 ZIP. The center's intake protocol includes crop hydration with electrolyte solution delivered via 1-mL syringe at 15-minute intervals for hypothermic or dehydrated birds weighing as little as 2.5 grams.
