“…Infections of S. laticeps of greater intensity (23 ± 36.8) and abundance (7.7 ± 22.3) were found in birds of prey in Spain [ 1 ]. Additionally, a study in the south of Spain reported that S. laticeps was the second-most prevalent helminth in 50 Eurasian eagle owls ( Bubo bubo ) [ 9 ]. Even though there are some reports of S. laticeps in raptors, including one from Portugal [ 8 ], the life cycle of this parasite is still not fully understood.…”

“…Clinically, a heavy infection with S. laticeps may cause ulcers in the proventriculus [4,5]. The species S. latipes has been identified in several birds around the world [3], including the black-winged kite (Elanus caeruleus), the Eurasian sparrow hawk (Accipiter nisus), the barn owl (Tyto alba), the longeared owl (Asio otus), the tawny owl (Strix aluco), the common kestrel (Falco tinnunculus), the common buzzard (Buteo buteo), and the Eurasian eagle owl (Bubo bubo) [1,[5][6][7][8][9]. Despite its widespread distribution, information about this nematode is still scarce.…”

The long-eared owl (Asio otus) is a medium-sized owl species that is well-distributed in almost all of the territories in Portugal. Nematodes were found in the oral cavity of a long-eared owl (A. otus) admitted to CRASSA (Wildlife Rehabilitation Centre of Santo André). During a physical exam and stabilization of the bird, five nematodes were collected. The worms were examined and measured under light microscopy, and photos were taken. After a morphological analysis was conducted, all the nematodes (five females) were identified as Synhimantus (Synhimantus) laticeps. Two specimens were subjected to molecular analysis, which confirmed the result. This study provides a combined morphological and genetic approach to S. laticeps. To the authors’ best knowledge, this is the first report including genetic sequencing of S. laticeps in a long-eared owl (A. otus) from Portugal.

“…Concerning definitive hosts, Heneberg et al ( 2018 ) confirmed by DNA sequence analysis, that S. falconis is using primarily birds of prey, particularly Buteo buteo (L.) and Circus aeruginosus (L.) (the type-host), less frequently species of Falco , while owls are considered as rare definitive hosts. Krone and Streich ( 2000 ) noted that S. falconis is the most often recorded trematode in birds of prey in Europe, and indeed, there are numerous reports regarding it as a common, generalist parasite of birds of prey (see Okulewicz et al 1993 ; Sitko 1998 ; Sanmartín et al 2004 ; Sitko et al 2006 ; Santoro et al 2010 ; Jantošková and Halán 2014 ; Komorová et al 2016 , 2017 ; Zafra et al 2022 ). Dubois ( 1968 ) in his compilation provided a long list of definitive hosts (Accipitriformes, Falconiformes and Strigiformes) from the Holarctic, including Great Britain, where S. falconis was recorded from Falco rusticolus islandus Brünnich, which is to the best of our knowledge the only record of S. falconis from a gyrfalcon (see Baylis 1939 ).…”

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.
