From buzzing songbirds to flashing wood-warblers, Colorado provides essential habitat for a wide array of bird species exhibiting bright golden-yellow plumage. Their vibrant coloration livens up backyards, woodlands, and wetlands across the state. Let’s explore some of the most eye-catching yellow birds to watch for in Colorado.

Western Meadowlark (Sturnella neglecta)

  • Features: Medium-sized songbird with bright yellow underparts, black “V” on breast, white stripe on flanks. Long slender bill. 
  • Locations: Common year-round resident in grasslands and fields across Colorado. 
  • Fun Fact: Sings a loud, flute-clear song from fence posts and other perches marking its breeding territory.  

Orange-crowned Warbler (Leiothlypis celata

  • Features: Olive green above with yellow underparts. Faint orange crown stripe. Active forager in shrubs and trees. 
  • Locations: Abundant winter resident and migrant across Colorado. Breeds farther north.

  • Fun Fact: Uncommon in the east. Female is yellow with gray wings. Male sings a hoarse, burry song.

Threats and Conservation

Habitat loss in breeding areas affects populations of many migratory yellow birds. Cats, collisions and climate change also take a toll. Conserving stopover habitats helps migrating species. Citizen science aids monitoring.

Citizen Science

Citizen scientists contribute greatly to knowledge and conservation of Colorado’s yellow birds:

  • eBird sightings provide researchers with valuable data on distribution, migration timing, population trends, range changes, and more. Photos help document rare species.
  • Breeding Bird Surveys help monitor populations long-term. However, coverage is still sparse in some areas of the state.
  • Nest box programs collect data on cavity nesters like Western Bluebirds. Monitoring provides info on reproduction, mortality, nest success.
  • Feeder surveys document irruptive species like Evening Grosbeaks when they move south in winter.
  • Bird banding helps track migratory patterns and demographics. Band recoveries show travels of individuals.
  • Christmas Bird Counts compile winter distribution data and highlight trends.
  • Atlas projects map ranges, breeding locales and habitat use.

Committed citizen scientists are crucial for monitoring diverse species like Colorado’s yellow birds over time. Their contributions inform research and conservation.


The diversity of yellow avian jewels sparkling in Colorado’s skies and trees provides ample rewards for birders. Note the plumage patterns, songs, behaviors and preferred habitats of these special species as you explore. Your sightings and actions can help conserve these migratory wonders.
