Serum proteins of selected Falconiformes and Strigiformes

Biochemical Systematics and Ecology, 1982
Abstract Blood samples were collected from ten species of raptors during the Fall 1980 migration in the vicinity of Green Bay, Wisconsin. Serum protein electrophoresis was performed on the samples in order to compare taxa based on biochemical information and relate this to current systematics.

Strix chacoensis (Aves: Strigiformes) as an accumulator of vertebrate material in an endangered world: Exploring new taphonomic and ecological perspectives

The Holocene
The objective of this study is to characterize the taphonomic signature of Strix chacoensis in bone and tooth remains of microvertebrates (birds and micromammals). The chaco owl is a bird of prey whose diet and bone modification patterns are little known.

Ordnung: Strigiformes – Eulen

2020
Der Stammbaum der Eulenvogel reicht seit der Abspaltung der „Nachtgreifvogel“ von den „Taggreifvogeln“ wenigstens 60 Mio. Jahre zuruck, wobei die Lebensform Eule nur einmal entwickelt wurde (monophyletisch). Nach Fossilfunden erfolgte die Aufspaltung in die beiden Familien Tytonidae (Schleiereulen-artige) und Strigidae (Eigentliche Eulen) im Miozan ...

Zoologiceskij zurnal
Data on Snowy Owl breeding settlements and encounters in the tundra were analyzed for the periods of 1996–2007, 2012, 2014–2020 in the vicinities of the Medusa Bay (73°21ʹN, 80°32ʹE), northwestern Taimyr Peninsula, Siberia.

Biochemical variability in four species of strigiformes

Biochemical Systematics and Ecology, 1991
Genetic variability in four species of Strigiformes was studied with multilocus enzyme electrophoresis, and results were used to estimate genetic diversity values. Strix aluco showed average values of polymorphism (P) and heterozygosity (H) higher than Tyto alba and Athene noctua.

The karyograms of some Falconiformes and Strigiformes

Chromosoma, 1966
The chromosome complements of cultured cells of the Falconidae are characterized by their low values: 2n=52 in Falco tinnunculus. 2n=68 in Buteo buteo, 64 in an unknown species (Accipiter nisus ?). The Strigidae have high chromosome numbers: 82 in Strix aluco and Athene noctua, 92 in Tyto alba.

Morphological assessment of the Common Barn Owl Tyto alba (Strigiformes: Tytonidae) supports three species

Zootaxa
Barn owls (Tytonidae: Tyto) have long been considered a single species, despite their worldwide distribution and despite being highly geographically variable in morphology. Multiple genomic studies have now demonstrated that the Common Barn Owl Tyto alba
