Broad-tailed Hummingbird

About the Broad-tailed Hummingbird

Colorado's signature hummingbird, arriving in April-May. Males produce a distinctive metallic trill in flight.

When to See Them in Colorado

Spring through fall. Watch for Broad-tailed Hummingbirds arriving in April–May as they move north through the Front Range corridor. Peak sightings typically occur during the spring migration window (late April through late May), then again during fall migration (August–October) when southbound birds stop to refuel.

During migration, Broad-tailed Hummingbirds concentrate at reliable food sources — making well-stocked feeders an excellent way to attract them. Keep your feeders filled through late May in spring and through October in fall to catch both migration waves.

What They Eat

In Colorado, the Broad-tailed Hummingbird's diet reflects what's locally available across seasons. At feeders, they're most drawn to Nectar (4:1 water to sugar ratio), which mirrors the high-energy foods they seek in the wild. Offering the right food in the right feeder is the single biggest factor in successfully attracting Broad-tailed Hummingbirds to your yard.

During nesting season (typically April–July on the Front Range), Broad-tailed Hummingbirds also rely heavily on insects as a protein source for their young — so a pesticide-free garden benefits them beyond just the feeder.

How to Attract Them to Your Yard

Creating a welcoming habitat for Broad-tailed Hummingbirds in Colorado is straightforward once you understand what they need. Here are the most effective steps our experts recommend:

• Hang a nectar feeder with a fresh 4:1 water-to-sugar solution — never use red dye. Clean feeders at least twice per week in warm weather to prevent harmful mold growth.
• Provide a clean water source year-round. A heated bird bath is one of the best investments you can make for winter birding along the Front Range — fresh water is often scarcer than food on cold days.
• Plant native shrubs and trees that produce berries or shelter nesting birds. Serviceberry, chokecherry, and native viburnums are excellent choices for Colorado front-range gardens.
• Keep feeders within 3 feet or beyond 30 feet of windows to minimize window strike risk — the most common cause of feeder-bird fatalities.
• Clean feeders regularly. Moldy or wet seed drives birds away and can spread disease through your local bird population. WBU No-Mess blends minimize hulls and spoilage.
