Clad in powder gray, dusty rose, and rich brown, the Gray-crowned Rosy-Finch breeds in harsh environments above the mountain treeline, only moving to lower elevations when significant snowfall makes finding food difficult. Adults can carry large amounts of food back to their chicks using storage pouches in their cheeks; this ability allows them to forage efficiently further from the nest.

The Gray-crowned Rosy-Finch breeds above the tree line in the mountains of western Canada, wintering at lower elevations in the same region and south into the western United States. Because of its remote breeding areas, population size is poorly understood, but it is likely that over half of the estimated total of 200,000 individuals breed in Canada, corresponding to a high level of responsibility. As such, trends from the continental Christmas Bird Count likely reflect the status of the Canadian population, but confidence in the large decrease is low because of limited precision in the trend. The national population of Gray-crowned Rosy-Finch is below its goal range.
The Gray-crowned Rosy-Finch is not well monitored by any Canadian survey because it remains at high altitudes for much of the year. Christmas Bird Count (CBC) data from the winter range are relevant, because a substantial portion of the Canadian population likely winters in the western United States. CBC results suggest a decrease in the continental population relative to the early 1970s. However, due to the mixing of the Canadian and American populations of Gray-crowned Rosy-Finch in the data and poor precision of the trend estimate, this assessment of the Canadian population is considered to be of low reliability.
The goal for Gray-crowned Rosy-Finch is to increase the population to the level it was at in the early 1970s, based on the Christmas Bird Count. Trend data show that Gray-crowned Rosy-Finch is far below its goal range although it has shown an increase over the past decade. However, because of the severity of the population decline since the early 1970s, it is not realistic for the goal to be met by 2050. Based on analysis of the historical population loss and potential growth rates, the interim target is to reach 30% of the goal by 2050. Achieving this target, and ultimately reaching the national goal for this species, will require ambitious and long-term conservation action.

Gray-crowned Rosy-Finch is reported fairly uniformly throughout the year in Canada, with some fluctuations as it moves between its alpine breeding habitats and its lower-elevation nonbreeding range.
