Abstract
We report colonisation by extra breeding pairs of Golden Eagles, and subsequent abandonments, in part of northeast Scotland during 1895-1985. Thenumber of pairs rose from three in 1895-1937 to eight by 1948, and then fell to four during 1959-71 in reverse of the colonisation sequence. This fits the concept of hierarchic quality of habitat used, or of bird quality. Possible mechanisms to explain this are discussed.
