Western Rufous Hummingbirds embark on an awe-inspiring migratory journey through the Rocky Mountains and adjacent lowlands from May to August, drawn by the flourishing wildflower season. They establish nests in our local region, exhibiting a fierce territoriality as they claim and defend their feeding territories. During winter, these remarkable birds seek refuge in wooded areas within the Mexican state of Guerrero, covering a staggering distance of over 2,000 mi (3,200 km) during their overland migration—a remarkable feat considering their diminutive size, weighing merely 3 to 4 grams (0.11 to 0.14 oz).

Distinguished by their vibrant orange and green-and-orange plumage, adult male rufous hummingbirds tend to commence their migration slightly earlier than females and young birds, typically departing by early August. However, by mid-August, the entire population has migrated, leaving behind a captivating spectacle.

These tiny aviators primarily sustain themselves by extracting nectar from flowers with their extendable tongues or catching insects mid-flight. To allure and accommodate these aerial wonders, we hang specialized feeders filled with a simple sugar syrup. The upkeep demands diligence, as these hummingbirds, buzzing with activity throughout the day, necessitate frequent refilling. In the summer of 2023, our record-breaking year, we welcomed an impressive daily visitation of 60-70 birds to our five large feeders, creating a vibrant display of natural splendor.

Renowned for their feisty nature, Western Rufous Hummingbirds captivate observers with their relentless interactions at flowers and feeders, providing endless amusement through their captivating antics.
