The most common owl in Britain and also known as the ‘Brown Owl’, this nocturnal species hunt a largely rodent diet in woodland. Tawny owls use their excellent hearing to find prey in the dark and use their ‘tawny’ coloured feathers to blend in perfectly with their habitat.
Tawny owls are actually the only owl to use “twit-twoo” as their call and this is made by two owls calling to each other

One from 2017 when I did my birds of Prey course. An intense stare from the Strix Aluco.
An owl's eyes are placed at the front of the head and have a field overlap of 50–70%, giving it better binocular vision than diurnal birds of prey (overlap 30–50%). The tawny owl's retina has about 56,000 light-sensitive rod cells per square millimetre (36 million per square inch); although earlier claims that it could see in the infrared part of the spectrum have been dismissed, it is still often said to have eyesight 10 to 100 times better than humans in low-light conditions. However, the experimental basis for this claim is probably inaccurate by at least a factor of 10. The owl's actual visual acuity is only slightly greater than that of humans, and any increased sensitivity is due to optical factors rather than to greater retinal sensitivity; both humans and owl have reached the limit of resolution for the retinas of terrestrial vertebrates.
Adaptations to night vision include the large size of the eye, its tubular shape, large numbers of closely packed retinal rods, and an absence of cone cells, since rod cells have superior light sensitivity. There are few coloured oil drops, which would reduce the light intensity. Unlike diurnal birds of prey, owls normally have only one fovea, and that is poorly developed except in daytime hunters like the short-eared owl.
I am ending this year with my favorite unposted shot from 2023.
Happy New Year and get great shots of wherever and whenever your photographic passion leads you.

Barred Owl
The Barred Owl (Strix varia), or Northern Barred Owl, is a true owl native to eastern North America. Adults are large, and are brown to grey with barring on the chest. Barred owls have expanded their range to the west coast of the United States, where they are considered invasive. Mature forests are their preferred habitat, but they are also found in open woodland areas. Their diet consists mainly of small mammals, but they are also known to prey upon other small animals such as reptiles and amphibians.

Meet "The Colonel"
This beautiful Owl has lived with Gord Court for the past 15 years. She was given to his care after she was hit by a car and became blinded in the left eye when she was about two and a half years old. She is pushing 18 years now. A Barred Owl can live to be forty in good captive care,
The Colonel is a veteran wildlife ambassador. Thousands of children have met her over the years as Gord has taken her to schools in the Edmonton area. She is very calm and gentle. Children have scratched her head and stroked her feathers.
Gord told me that he loves to get children to touch something alive and out there in the real world instead of focusing on their hand held devices.
Dr. Gord Court is a senior wildlife status biologist with Alberta Wildlife and Parks.
Chouette rayée | Barred Owl | Strix varia
Grand merci à toutes et tous, à votre façon, pour m'avoir permis de savourer cette première rencontre à Angrignon!!! Merci à Robert, Jean-Guy, Tim, Marie-Claude et Normand...
Merveilleuse première rencontre à Angrignon!
Enfin! Je l'ai rencontré cette nouvelle visiteuse du Parc Angrignon! Découverte par Robert Dupont il y a près deux semaines, et vu à nouveau dimanche dernier par Jean-Guy Proulx et Tim Ellwood, je suis venu ce midi faire ma tournée habituelle des trous des Petits-ducs maculés et aussi chercher à nouveau cette belle Chouette! Arrivé à l'arbre des trous 7, 8 et 9, j'y reviendrai au sujet des ses locataires lors de ma prochaine chronique, à ne pas manquer d'ailleurs, j'ai rencontré Jean-Guy Proulx en compagnie de Marie-Claude Paquette et Normand Coutu qui m'informaient avoir observé longuement la Chouette rayée non loin de là. Jean-Guy m'y a guidé. Arrivé dans le secteur Tim, qui l'avait suivi dans ses derniers déplacements, nous a indiqué sa position. Elle était perché sous le feuillage d'un arbre à une hauteur de tout au plus 12 pieds en face du sentier qui fait le tour du grand bassin. Non seulement nous avons pu l'observer et la capter tout à notre guise, de nombreux promeneurs ont aussi pu apprécier sa merveilleuse présence. Émouvante rencontre, comme toujours. Elle exerce sur moi une fascination toute particulière cette Chouette que nous rencontrons normalement davantage à partir du milieu de l'automne et en hiver dans nos boisés urbains.
Un rêve remontant à ma toute première observation d'une Chouette rayée en février 2015 s'est donc réalisé, en observer une au Parc Angrignon, et ce, à quelques minutes de chez moi. Pur bonheur! Voici ma première image d'une série à venir, quoique les conditions lumineuses n'étaient pas optimales, nous avons bénéficié d'une telle proximité qu'il fut tout de même possible de la compenser en partie. Une première aussi pour moi d'en croiser une si tôt à l'automne... et cela presque dans ma cour!!!
