摘要：

We investigated interactions between the Black Redstart (Phoenicurus ochruros) and the St. Lucie cherry (Prunus mahaleb) in two rocky areas in northwest Spain. Black Redstarts are responsible for about 30 % of P. mahaleb fruit consumption in these areas (604 of a total of 1 854 observations of birds feeding; 56 trees. 4 years). On average 14 % of food deliveries to nestlings comprised P. mahaleb fruits (total 8 nests, 3 years; range for individual nests 7-28 %). The proportion of deliveries comprising fruits was higher during the second half of the nestling period than during the first half. Birds generally alighted on rock after leaving P. mahaleb plants (74 % of cases). Nine-month seed-survival experiments performed in the study area indicate significant variation among the three substrate types considered (grass, rock, rock-under-nest).
