Not All Nest Boxes Are Equal When It Comes To Eurasian Roller Conservation
In dealing with anthropogenic disturbance, one of the most difficult conservation/management issues is that different human activities impact different species in different ways. Removal of trees and hedges, for example, may reduce the amount of feeding or sheltering area available for some animals, while for others it may take away places for potential nest building. For the Eurasian roller (Coracias garrulus), it is this last problem that causes the biggest difficulties, but only in an indirect way. These birds are secondary cavity-nesters, meaning that, because they cannot excavate their own cavities to nest in, they rely on holes dug by others. Thus, when species like woodpeckers have nowhere to create their nests, neither do rollers.read more
