Strigidae – Owls
Owls, my favourite birds
by Friedhelm Weick
Owls are outstanding birds! Is it their silent hunting in the poor evening light and at night, their distinctive appearance – huge head and forward looking eyes or maybe the echoes of ancient myths and tales of woodland goblins and bewitched owl-shaped princesses? However, since my childhood owls were my favourite birds. They even outranked my ambition for the diurnal birds of prey. As a wildlife artist, birder and ornithologists – I never lost my contact to these feather-armoured knights of the twilight. When in 1980 my book Birds of Prey of the World (Parey, Berlin) was printed, I had the idea for a similar project on the strigiformes of the world. So I began to collect every bit of information about this subject – and, remember: the Internet wasn’t in reach for the common wildlife artist then.
I filed scientific articles, photos and colour-copies of books, sketches and other descriptions back to 1758, photos from living owls in the wildlife or captivity. Detailed lists of measures and colours of skins, weights and feathers grew larger and larger. Beside that I visited zoological gardens, ornithological institutes and a lot of private owl-keepers, birders and ornithologists. In the early nineties I wrote three different annotated checklists about Strigiformes. The first included all recent complete taxa and their distribution. A second listed all-important measurements and weights linked to an index of photos and paintings. The third list was a full description of plumages and soft parts combined with a detailed bibliography.
In this situation Claus König head of the Natural Science Museum at Stuttgart and ambitioned ornithologist asked me if I would be interested in a project which should result in nothing minor than the standard guide to all owls of the world. The publisher would be Pica Press, Sussex. Of course I was, wasn’t I?
The three checklists were the basic-stock for our further work. In the following years I examined some thousands of skins and mounted owls in all-important museums of the world, only supported by my dear wife Christel. Within nearly three years I painted all different taxa and morphes that were sometimes known only by one skin…
In 1999 the book was published… leaving me more time for birding and outdoor projects and, last but not least for new paintings of my favourite birds, guess which?

Burrowing Owls Athene cuniculariaSpecies AccountThe burrowing owl (Athene cunicularia) is a small, long-legged owl found throughout open landscapes of North and South America. Burrowing owls can be found in grasslands, rangelands, agricultural areas, deserts, or any other open dry area with low vegetation.

Pernambuco Pygmy Owl Glaucidium mooreorumCornell Species AccountThe Pernambuco Pygmy-Owl is a northeast Brazilian endemic, apparently confined to the state of the same name, and one of the most poorly known of all Neotropical birds. It was described to science as recently as 2002, based on two specimens collected in Saltinho Biological Reserve in 1980, and the species is speculated to already be on the brink of extinction.

Pernambuco Pygmy Owl Glaucidium mooreorumBirdLife Species Account
Pernambuco Pygmy Owl Glaucidium mooreorumSpecies AccountThe Pernambuco Pygmy Owl (Glaucidium mooreorum) was first described in December 2002 when two study skins were examined in Pernambuco, Brazil. The skins were originally collected in 1980 and thought to be subspecies of the Least Pygmy Owl (Glaucidium minutissimum) or Amazonian Pygmy Owl (Glaucidium hardyi). Upon closer examination of the skins, and vocalisations of the birds also obtained in 1980, it was concluded that this was a new species. The name mooreorum was chosen in honour of Dr. Gordon Moore and his wife Betty, who have made significant contributions to conservation…

Short-eared Owl Asio flammeusHBW Species AccountTaxonomy: Strix Flammea Pontoppidan, 1763, Denmark.Morphologically similar to A. otus, but studies of proteins indicate unusually large genetic distance between them. Sometimes thought to be closely related to A. capensis, which replaces it ecologically in Africa, but resemblance seems superficial and probably due to convergence, and vocalizations very different.

Short-eared Owl Asio flammeusRSPB Species AccountShort-eared owls are medium sized owls with mottled brown bodies, pale under-wings and yellow eyes. They are commonly seen hunting during the day
Snowy Owl Nyctea scandiacaCornell Species AccountIt appears that Snowy Owls can be aged and sexed fairly reliably in the hand using a number of feather shape and color characters (see Pyle, P. 1997. Identification Guide to North American Birds. Part I. Slate Creek Press, Bolinas, CA); the utility of these characters in field ID is much more limited. Although I doubt anyone could definitely assign "second year female" status to a bird not in the hand, owls encountered in the field can probably be put in a couple of general categories (adult male, first year or immature male, female). Below are some photos of specimens from the Cornell University Museum of Vertebrates collection that illustrate these characters.
Snowy Owl Nyctea scandiacaHBW Species AccountTaxonomy: Strix scandiaca Linnaeus, 1758, Lapland, north Finland. Previously placed in monotypic genus Nyctea, primarily on basis of skull characters; recent genetic study, however, indicated that it is part of the Bubo lineage. Monotypic.
Snowy Owl Nyctea scandiacaSpecies AccountThe Snowy Owl was first classified in 1758 by Carolus Linnaeus, the Swedish Swedish naturalist who developed binomial nomenclature to classify and organise plants and animals. The name scandiaca is a Latinised word referring to Scandinavia, as the Owl was first observed in the northern parts of Europe. Some other names for the Snowy Owl are Arctic Owl, Great White Owl, Ghost Owl, Ermine Owl, Tundra Ghost, Ookpik, Scandinavian Nightbird, White Terror of the North, and Highland Tundra Owl. It is the official bird of Quebec…

Snowy Owl Nyctea scandiacaSpecies AccountThe snowy owl (Bubo scandiacus) is a large, white owl of the typical owl family. Snowy owls are native to Arctic regions in North America and Eurasia. Males are almost all white, while females have more flecks of black plumage. Juvenile snowy owls have black feathers until they turn white. The snowy owl is a ground nester that predominantly hunts rodents.

Hawk & Owl TrustWebsiteWelcome to The Hawk and Owl Trust Website. Owls, hawks, eagles, falcons - magnificent birds like these symbolise freedom and wild places. The Hawk and Owl Trust is dedicated to ensuring that birds of prey survive in the wild for future generations to enjoy. Founded in 1969 because of concerns about the alarming decline in numbers of peregrines and other raptors, today we work to conserve all wild birds of prey and their habitats in the face of mounting human pressures
International Owl SocietyWebsiteThe intention being that this should provide a world-wide forum for all those interested in owls. Set out below are the objectives and intentions of this organisation and everybody with an interest in this Family are cordially invited to apply for membership. Most certainly the International Owl Society cannot succeed without an energetic and committed membership and the Council looks forward to receiving your active support. Any suggestions as to how the objectives and intentions may be expanded or amended to better reflect the interests of the Members are most welcome and will be carefully considered
World Owl TrustWebsiteWe are the only organisation that works solely on owl conservation on a global scale, and we have members in many countries around the world. Our conservation programmes are a last ditch attempt to protect populations of endangered owls until we have succeeded in restoring their habitat. This is the purpose of our Owl Centre. If we succeed in breeding from the birds we hold we can reintroduce them back into to the wild. This has already been achieved for the European Eagle Owl and British Barn Owl.

It breeds thinly across the UK with fewer birds in the south-west and Wales. Northern birds migrate southwards, including birds from Europe coming to spend the winter in the UK, while southern birds are residents and only move short distances to find food...
