“…The first record of S. falconis from F. rusticolus islandus was provided by Baylis ( 1939 ) from Argyllshire, Scotland; however, without any further details, therefore we can only speculate about the origin of the Icelandic gyrfalcon in Scotland. Apart from the finding of Baylis ( 1939 ), there is only one more record of S. falconis from gyrfalcons from a kennel in Tuva, Russia, in South Siberia (Davydova et al 2016 ); however, this identification should be viewed with caution, as it is based on eggs only and is not supported by molecular genetic data. The only other strigeid from a gyrfalcon is S. macropharynx described by Dubois and Rausch ( 1965 ) from Alaska, USA.…”

Strigea falconis is a common parasite of birds of prey and owls widely distributed in the Holarctic. We aimed to characterise S. falconis from Iceland via integrative taxonomic approach and to contribute to the understanding of its circulation in the Holarctic. We recovered adult S. falconis from two gyrfalcons (Falco rusticolus) collected in 2011 and 2012 in Iceland (Reykjanes Peninsula, Westfjords) and characterised them by morphological and molecular genetic (D2 of rDNA, cox1, ND1 of the mDNA) methods. We provide the first species record of S. falconis in Iceland which to the best of our knowledge is its northernmost distributional range. The presence of S. falconis in Iceland is surprising, as there are no suitable intermediate hosts allowing completion of its life cycle. Gyrfalcons are fully sedentary in Iceland; thus, the only plausible explanation is that they acquired their infection by preying upon migratory birds arriving from Europe. Our data indicate that the most likely candidates are Anseriformes and Charadriiformes. Also, we corroborate the wide geographical distribution of S. falconis, as we found a high degree of similarity between our haplotypes and sequences of mesocercariae from frogs in France and of a metacercaria from Turdus naumanni in Japan, and adults from Buteo buteo and Circus aeruginosus from the Czech Republic. The case of Strigea falconis shows the advantages of a complex life cycle and also depicts its pitfalls when a parasite is introduced to a new area with no suitable intermediate hosts. In Iceland, gyrfalcons are apparently dead-end hosts for S. falconis.

“…Although helminth infections cause morbidity and mortality in captive and wild birds of prey, helminths are not usually considered important pathogens ( Krone and Cooper, 2002 ; Krone, 2007 ). However, few studies have dealt with the pathogenicity and impacts of helminths in wild populations of birds of prey ( Ward, 1975 ; Redig, 1993 ; Smith, 1993 , 1996 ; Lacina and Bird, 2000 ; Krone and Cooper, 2002 ; Krone, 2007 ; Atkinson et al, 2008 ; Coulson et al, 2010 ; Santos et al, 2010 ; Andery et al, 2013 ; Vasilevytch et al, 2016 ).…”

Bacteriological studies of material from the pharynx and cloaca from clinically healthy saker falcons and eastern imperial eagles under aviary captive conditions were carried out. Indicated are eleven cultures of pathogenic and conditionally-pathogenic microorganisms represented in the association. Microscopic examination of blood in erythrocytes revealed hemosporidia. Conducted macro – and microscopic, as well as helminthological study of feces. The invasion rate was 32.6%. Revealed 2 types of helminths. The obtained results may indicate persistent carriage of the causative factor of infections and the formation of foci of helminthiases and haemosporidia.
