Saturday is World Migratory Bird Day, an annual observance that promotes conservation efforts for migratory birds and celebrates their journeys. Carlsbad is located along the “Pacific Flyway,” one of four bird migration routes in North America, spanning from Alaska to the tip of South America.

Among the millions of migratory birds that travel along the Pacific Flyway is the blue grosbeak (Passerina caerulea), which heads north to breed every year after spending the winter in Mexico and Central America. Carlsbad’s more than 6,200 acres of natural open space make it a popular spot for the blue grosbeak and other migratory birds.

As the weather warms up, you may be able to spot a blue grosbeak at Lake Calavera Preserve. They like to nest near water sources and in mostly open fields with few trees and shrubs. Finding a blue grosbeak may require a little bit of patience. You’re likely to hear its distinctive song before you see it.

• Listen for the songbird’s call, a flute-like song with sharp call notes.
• Look for the vibrant blue color of the male blue grosbeak against green foliage. (Females have a more discreet cinnamon brown color.)

The City of Carlsbad’s ongoing habitat protection efforts are critical to migratory birds like the blue grosbeak, even if they only call Carlsbad home part-time. Birds support balanced ecosystems by regulating insect populations and shaping plant communities through seed dispersal and pollination, helping to keep our planet healthy. Supporting a healthy environment is a key goal in the City Council’s 5-Year Strategic Plan.
