La parte superior en el adulto es de color gris azulado mientras que la parte inferior es de color canela; tiene una garganta blanca y el rostro cuenta con una raya negra que atraviesa los ojos, un pico recto gris y una corona de color negro. Su llamado, que ha sido comparado con una trompeta de estaño, es agudo y nasal. Se reproduce en bosques coníferos de todo Canadá, Alaska y el noreste y oeste de los Estados Unidos. Aunque con frecuencia en un residente permanente, se irrumpe regularmente más al sur, si escasea el suministro de comida. Hay constancia de vagabundeo de la especie en zonas tan meridionales como la costa del Golfo y el norte de México. Forrajea en los troncos y ramas grandes de los árboles, a menudo descendiendo la cabeza primero, a veces captura insectos en pleno vuelo. Se alimenta sobre todo de insectos y semillas, en especial de coníferas. Se excava su nido en la madera muerta, a menudo cerca de la tierra, untando la entrada con resina.
