In the European pied flycatcher (Ficedula hypoleuca), researchers assert that males exhibit polyterritoriality in order to deceive females of the species into entering into polygynous relationships.
It was formerly regarded as a race of European Pied Flycatcher, but Sætre et al. (2001) recommended that it is regarded as a species in its own right.
Studies were also done to examine the amount of contribution the male European Pied Flycatcher provided in parental care as well as why some females choose to mate with mated males.
Elevated levels of nestling testosterone are correlated with more intense begging displays in Canarys, Slender-billed Prions (Pachyptila belcheri) and European Pied Flycatchers (Ficedula hypoleuca).

Non-breeding males, females and juveniles have the black replaced by a pale brown, and may be very difficult to distinguish from other Fidecula flycatchers, particularly the European Pied Flycatcher and the Semicollared Flycatcher, with which this species hybridizes to a limited extent (Veen et al. 2001).
