Mammalian prey for common buzzards other than rodents, insectivores and lagomorphs is rarely taken. The Lynx genus usually hunts lagomorphs, or hares and rabbits. Commonly seen lagomorphs include the cottontail rabbit and commonly seen rodents include squirrels. Of the lagomorphs only hares and rabbits are represented in Scotland. This is also done by lagomorphs like rabbits and pikas. Reservoir hosts of importance can include lagomorphs (e.g. rabbits), rodents, galliform birds, and deer. It preys on small terrestrial mammals, such as armadillo, opossum and lagomorphs. Despite the evolutionary relationship between lagomorphs and rodents, the two orders have some major differences. The three European lagomorphs are the European rabbit, mountain hare and European hare. Initially it was intended to publish only one volume on lagomorphs and rodents. Their description, in 2005, helped to bridge the gap between more typical rodents and lagomorphs. In North America, where mammals are more important in the diet, more lagomorphs are taken. The Arctic hare is one of the largest living lagomorphs. This family consists of 12 genera, containing a total of 62 species of lagomorphs. However, sometimes long-eared owls can very rarely capture exceptionally large lagomorphs.
