Its absence from some other localities may be due to the smaller quantity of material collected or an untimely collection (at minimum annual incidence). It prefers beech, but particularly oak forests, though it frequently occurs also in spruce woods. C. sciurorum is one of the species that abound also in bird nests (authors'private collections). It may therefore be said that through its hosts (dormice) it ensures contact between small mammals and birds. The second most abundant ecological flea group occurring on dormice comprises species characteristic of birds, the most numerous being those parasitizing birds nesting in hollow trees. They amounted up to 94.18 % of all bird fleas (C. gallinae, C. fringillae, C. pullatus, C. tribulis). They have the same ecological requirements as does C. sciurorum, but have a markedly lower ecological potential as they are specialized
