Gray-Crowned Rosy-Finch
leucosticte tephrocotis
The Gray-Crowned Rosy-Finch is a rugged and charismatic songbird built for survival in some of North America's most extreme environments. Living high above the timberline in alpine tundra, talus slopes, and windswept glaciers, this resilient member of the finch family is a true mountaineer. Known for its remarkable tolerance to freezing temperatures, it can often be seen hopping actively across snowfields in search of wind-blown insects and seeds. During the winter, harsh alpine weather drives these hardy birds down to lower elevations, bringing their vibrant presence to mountain valleys and backyard bird feeders. Their highly adaptive foraging strategies and specialized anatomical features allow them to thrive where few other birds dare to nest.
Hábitat: Typically found in high-altitude alpine tundra, rocky talus slopes, and glaciers above the treeline during the summer, migrating to lower montane valleys in winter.
Aspecto
This medium-sized finch features a warm, dark brown body contrasted beautifully with brilliant rosy-pink washes on its wings, rump, and belly. A distinctive ash-gray patch crowns the back of its head and cheeks, while its forehead is marked by a stark black patch. Its bill undergoes a striking seasonal transformation, changing from a sharp, dark black during the breeding season to a bright yellow during the winter months. They have long, pointed wings and a notched tail, which help them navigate the turbulent mountain winds.

Datos interesantes
In severe winter weather, they can form massive nomadic flocks of several thousand birds as they descend into valleys in search of food.
Their specialized throat pouch allows parents to collect and transport dozens of insects at a time back to their hungry chicks.
They are among the highest-altitude nesting birds in all of North America, often building nests in rock crevices above the treeline.
