Surnia
genre de Strigidae dans Strigiformes

Nom vernaculaire Nom scientifique Nom spécimens
Épervière boréale
Surnia ulula 		Surnia ulula 3 3

Die Gattung Surnia ist bisher monotypisch - es existiert also nur eine Art in dieser Gattung.
Da die Sperbeule (S. ulula) jedoch in der kompletten, borealen, nördlichen und polarnahen Hemisphäre in mehreren Unterarten vertreten ist (von Nordamerika ostwärts bis Nordost-Asien), ist es recht wahrscheinlich, dass die Art aufgrund genetischer Untersuchungen in mehrere Arten gesplittet wird.
