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?

  • Hawk & Owl Trust

    Website
    Welcome 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 Society

    Website
    The 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 Trust

    Website
    We 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.

  • Long-eared Owl Asio otus

    Information
    The long-eared owl is medium-sized owl, smaller in size than a woodpigeon. It often looks long and thin, with head feathers (known as ear tufts even though they are not ears) which it raises when alarmed. It is buff-brown with darker brown streaks, and deep orange eyes. 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...
