1. High-Altitude Residents: Rosy-Finches are true alpine specialists, with some populations spending their entire lives above treeline in the highest mountains of North America. They actually have larger lungs and more hemoglobin in their blood to help them breath in think mountain air!

2. Breeding Adaptations: Rosy-Finches have specialized adaptations for breeding in alpine environments, including thick down feathers for insulation and low metabolic rates to conserve energy in cold temperatures.

3. Social Birds: Rosy-Finches are social birds that often forage and roost in large flocks, providing safety in numbers and opportunities for social interaction.

4. Distinctive Vocalizations: Rosy-Finches have soft, melodious calls that are often heard echoing through the mountains during the breeding season, serving as a reminder of their presence in these remote landscapes.

5. Moved From Asia: About 250,000 years ago the ancestors of today’s Rosy-Finches moved across the islands separating Asia to North America.

6. One Species: Until the early 1990’s all three species of North American Rosy-Finch were considered a single species.
