The Rook (corvus Frugilegus L.), Its Nesting in the Slovakia and Relationship towards Agricultural Land
The rook (Corvus frugilegus L.) is one of the greatest corvine birds dependent on open agricultural land. With the onset of spring, hundreds of thousands of rooks flocks which wintered in Slovakia, this area leaves and returns to its breeding grounds in north-eastern Europe. Wintering populations will be replaced by our rooks, in Slovakia nesting, which wintered in France and Spain. Nesting pop...
متن کاملbiodiversity and prevalence of parasites of rook (corvus frugilegus) in iran
background : rooks are distributed all over iran and no information is available in the literature on their parasitic infections. methods : one hundred twenty five rooks were examined at post-mortem for parasitic infections. results : two species of cestodes, 5 species of nematodes and 4 species of protozoa were found of which all were new host and distribution record. conclusion : rooks have ...
متن کاملCooperative problem solving in rooks (Corvus frugilegus).
Recent work has shown that captive rooks, like chimpanzees and other primates, develop cooperative alliances with their conspecifics. Furthermore, the pressures hypothesized to have favoured social intelligence in primates also apply to corvids. We tested cooperative problem-solving in rooks to compare their performance and cognition with primates. Without training, eight rooks quickly solved a...
متن کاملEffect of spatial resolution of soil data on predictions of eggshell trace element levels in the Rook Corvus frugilegus.
Although a considerable research effort has gone into studying the dietary pathways of metals to the bodies of laying female birds and their eggs in recent years, no detailed investigations have yet been carried out relating the properties of the biogeochemical environment at large spatial scales to eggshell trace element levels in typical soil-invertebrate feeding birds under natural condition...
متن کاملInvestigating Physical Cognition in Rooks, Corvus frugilegus
Although animals (particularly tool-users) are capable of solving physical tasks in the laboratory , the degree to which they understand them in terms of their underlying physical forces is a matter of contention. Here, using a new paradigm, the two-trap tube task, we report the performance of non-tool-using rooks. In contrast to the low success rates of previous studies using trap-tube problem...
