Caught these beautiful Black-headed Grosbeaks passing through Chatfield State Park during fall migration. Safe travels south! 🍂🦅 Fun fact! The Black-Headed Grosbeak is one of very few birds that can eat Monarch Butterflies! Due to the toxic nature of Monarchs they feed on them in an eight day cycle to allow the toxins to be cleared from their body! 📸: Nikon D850 🔭: Nikon 200-500mm f/5.6 ⚙️: 500mm | f/5.6 | 1/1250s | ISO 220-1250 📍: Chatfield State Park, Colorado 📅: September 5, 2026 #blackheadedgrosbeak #birdphotography #fallmigration #chatfieldstatepark #wildlifephotography
