Rocuronium bromide has recently been reported to dilate the pupil of orange-winged parrots (Amazona amazonica) (36) and several other species of birds, including Hispaniolan Amazon parrots, (37,38) tawny owls (Strix aluco
), (39) common buzzards (Buteo buteo), little owls, (40) and European kestrels (Falco tinnunculus).
The retinae were taken from eyeballs of four Strigidae genera: little owl (Athene noctua), tawny owl (Strix aluco
), scops owl (Otus scops) and eared owl (Asio otus).

(2003) found smaller male Tawny Owls (Strix aluco
) provisioned nestlings more often than females during the post-brooding period and had larger home ranges than females but did not deliver larger prey.
2008: Does the diet of an opportunistic raptor, the tawny owl Strix aluco
, reflect long-term changes in bat abundance?
However, studies of Northern Spotted Owls (Strix occidentalis caurina; Forsman and others 2011), and Tawny Owls (Strix aluco
; Karell and others 2009) showed no sex differences in adult annual survival.
In turn, Accipiter gentilis and Strix aluco
had their highest abundance in the middle of the study period, as indicated by positive correlations with Axis 2 (r = 0.61 and r = 0.58, respectively).
And now lead-author Julien Gasparini of the Laboratory of Ecology and Evolution at the Pierre and Marie Curie University in Paris, and his colleagues have shown that female tawny owls (Strix aluco
) with dark red plumage mount a more powerful response to infection than females with lighter feathers.
