Abstract
From 1986 to 1989 two adoptions in Spanish Emperial Eagle were recorde d involving 5.5 % of the fledglings. The results of blood analyses sho w that values of the adopted fledglings were not the highest for varia bles indicative of chronic malnutrition. Both adoptions involved nests nearest to one another. These observations support the view that adop tions result from the unusual proximity between nests.
