Nebraska Bird Review

CATTLE VS. WATERFOWL. After three years of comparatively dry weather that kept our rainwater basins dry most of the time, in 1982 we had lots of rain and lots of water in our basins. The rains started the latter part of April and the waterfowl and shorebirds came in great numbers. Although the water levels raised with each rain, the vegetation grew fast enough to keep most of the water covered. This is where the nesting population of Coots, Pied-billed Grebes, etc., hide their nests, and it is hard to guess how many birds are nesting or where the nests …

Scaring Of Carrion Crows (Corvus Corone Corone) By Species-Specific Distress Calls And Suspended Bodies Of Dead Crows, Luzia Naef-Daenzer

Bird Control Seminars Proceedings

In Switzerland, carrion crows can cause considerable damage to sprouting corn fields when feeding on the germinated corn. I tried to evaluate a method to prevent these damages. The use of species-specific distress calls, for the first time described by Frings and Jumber (1954), seemed to be the most promising method. Agronomes and biologists have applied it in field studies to several different bird species causing damage in agriculture and on airports (e.g., Gramet, 1962; Brough, 1968). However, the literature either describes single actions or several different scaring devices being used together. To be able to judge the method, quantitative …
