Trypanosomes of some Fennoscandian birds

Abstract

Linear measurements and derived indices of trypanosomes from four species of Fennoscandian birds were compared to those reported for Trypanosoma avium, T. everetti, T. ontarioensis and T. paddae. The trypanosomes encountered in the Fennoscandian birds were identified as T. avium fr om Tengmalm's owl Aegolius funereus and the pied flycatcher Ficedula hypoleuca, T. everetti from the great tit Paras major and collared flycatcher F. albicollis and T. ontarioensis from the collared flycatcher; T paddae was not seen.
