Temporal and spatial differences in the feeding ecology of the Spanish Imperial Eagle Aquila adalberti during the non-breeding season: effects of the rabbit population crash

The paper describes the diet of territorial Spanish Imperial Eagles during the non-breeding season, comparing prey identified across different regions (Central, Western and Southern), breeding season vs non-breeding season, and periods (1983–1985 or pre-viral haemorrhagic disease [RHD] vs 1991–2000...
