beveridgei was reported in Accipiter nisus
and Buteo buteo; and P.
In contrast, a much stronger negative correlation between those two variables was counteracted in Accipiter nisus by a strong positive indirect effect of [P.sub.juv] on [P.sub.ad], leading to a large integrated elasticity for adult survival.
For instance, the high covariation among the elements in the projection matrix of the Accipiter nisus population was computed during a period when the population increased rapidly in size, probably due to a large reduction of the pesticide levels in the environment (Wyllie and Newton 1991).

The diets of Eurasian sparrowhawk Accipiter nisus and Black kite Milvus migrans occupying Lal Sohanra National Park at Bahawalpur, southern Punjab were analyzed.
The Eurasian sparrowhawk Accipiter nisus and black kite Milvus migrans commonly found in open woodlands, marshes, desert grassland, partially cleared lands, and cultivated fields.
Table I.- Pellet analysis of Eurasian sparrowhawk Accipiter nisus: prey items (%) and their biomass (%).
Results showed IOP values varied by family and species, with the following mean IOP values (mm Hg [+ or -] SD) determined: white-tailed sea eagle (Haliaeetus albicilla), 26.9 [+ or -] 5.8; red kite (Milvus milvus), 13.0 [+ or -] 5.5; northern goshawk (Accipiter gentilis), 18.3 [+ or -] 3.8; Eurasian sparrowhawk (Accipiter nisus), 15.5 [+ or -] 2.5; common buzzard (Buteo buteo), 26.9 [+ or -] 7.0; common kestrel (Falco tinnunculus), 9.8 [+ or -] 2.5; peregrine falcon, (Falco peregrinus), 12.7 [+ or -] 5.8; tawny owl (Strix aluco), 9.4 [+ or -] 4.1; long-eared owl (Asio otus), 7.8 [+ or -] 3.2; and barn owl (Tyto alba), 10.8 [+ or -] 3.8.
In northern goshawks (Accipiter gentilis), common buzzards, and common kestrels (Falco tinnunculus), significant differences in IOP between juvenile and adult birds were found (P [less than or equal to] .001), but not in Eurasian sparrowhawks (Accipiter nisus) (P = .10) and tawny owls (P = .26).
From a 19-yr study of Sparrowhawks, Accipiter nisus, in south Scotland, we now have data from enough old females to examine changes in both survival and reproduction that occur throughout the natural life-span.
The data used here derive from the Sparrowhawks, Accipiter nisus, nesting in one 200 [km.sup.2] area, centered on Eskdale, in south Scotland (55 [degrees] 16[minutes] N, 3 [degrees] 25 [minutes] W).
At least some of the female disappearance was caused by predation by the European Sparrowhawk (Accipiter nisus).

There is evidence of permanent emigration by female Sparrowhawks (Accipiter nisus
