The Gray-crowned Rosy-Finch is not well monitored by any Canadian survey because it remains at very high altitude for much of the year. Christmas Bird Count (CBC) data from the wintering grounds in the United States 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 Gray-crowned Rosy-Finch is currently below the lowest acceptable level relative to its national population goal (see graph below).
