Once confined to Baja California and Southern California, Anna\u2019s Hummingbirds expanded dramatically northward, reaching as far as Alaska. This expansion was fueled by San Diego\u2019s proliferation<\/strong> of ornamental gardens, eucalyptus trees, and nectar-rich landscapes. Today, they thrive here year-round, flitting through chaparral, suburban yards, and parks like Balboa Park, where their metallic chirps are a familiar soundtrack .<\/p>\n\n\n\n

  • Females<\/strong>: Lack the ruby hood but often show a small, iridescent red throat patch. Their mottled gray-green underparts distinguish them from other species .<\/li>\n\n\n\n
  • Size<\/strong>: Tiny but mighty\u2014just 4 inches long, weighing less than a nickel, with a wingspan of 4.5\u20135 inches .<\/li>\n<\/ul>\n\n\n\n

    Fun fact<\/em>: Their iridescence isn\u2019t from pigment! It\u2019s structural color<\/strong>, created by light refracting through feather platelets .<\/p>\n\n\n\n

          \n
        1. Insect Surprise<\/strong>:
          Unlike most hummingbirds, Anna\u2019s rely heavily on insects and spiders<\/strong> (up to 80% of winter diet). This protein boost lets them endure colder months when flowers fade\u2014a key to their San Diego residency .<\/li>\n\n\n\n
        2. Dive Displays & Courtship<\/strong>:
          Males perform dramatic courtship dives<\/strong>, climbing 130 feet before plunging at breakneck speed. At the dive\u2019s bottom, tail feathers produce a loud pop<\/em> to impress females. After mating, females solo-build nests (from spider silk and lichen) and raise chicks .<\/li>\n<\/ol>\n\n\n\n
