Item description from seller

Bivalves and gastropods dropped by hooded crows (Corvus corone cornix) show - not surprisingly - a similar fragmentation as those dropped by herring gulls (Larus argentatus). Both bird species drop the shells from some height to crack them. Bivalves have one or both valves fragmented, but the valves still hold together by the ligament. Gastropods have either the spire broken off or a large hole in the body-whorl, sometimes also in the penultimate whorl. This hole is often opposite the aperture leaving the outer lip undamaged. Such large holes seem characteristic for shells dropped by birds. Stomatopods also make holes in shells but these are usually smaller. 5 pp., 2 pls, gr. 8.
