Thông tin trong bài: "It is not surprising that a bird in heavy molt often seems listless and unwell. But far from being random, molt is controlled by strong evolutionary forces that have established an optimal time and duration." (Không có gì ngạc nhiên khi một con chim đang thay lông nhiều thường có vẻ bơ phờ và không khỏe. Nhưng không phải là ngẫu nhiên, quá trình thay lông được kiểm soát bởi các sức mạnh tiến hóa mạnh mẽ mà đã xác định thời gian và khoảng thời gian tốt nhất.)
