The effects of raptor predation on wintering wader populations at the Tyningharne estuary, southeast Scotland
Raptor predation on waders was studied by direct observation of raptors hunting a known wader population and subsequent recovery of dead waders. In each of three winters, raptor predation was shown to be the most significant cause of mortality in most small wader species, Sparrowhawks Accipiter nisu...
