Since 2011, he has been the assistant professor at the Department of Bird Diseases, Faculty of Veterinary Medicine in Olsztyn. Among his existing scientific achievements there are numerous studies regarding, inter alia, pigeon pathology and epidemiology of selected infectious diseases in the population of these birds, as well as publications on bird immunology and selected issues concerning the health of free-living birds. In addition, he is the author of numerous publications, mainly related to the pathology of pigeons, which appeared in esteemed veterinary press. His main research interests revolve around the pigeon circovirus infection (PiCV), and the potential possibilities of the control and prevention against YPDS. Currently he conducts research on the immunology of PiCV infection in pigeons. Besides the scientific work, he also deals with the treatment of pigeons and other domesticated birds.


Professor, Ph.D. Piotr Szeleszczuk: veterinarian, a specialist in the diseases of poultry and ornamental birds. He is the head of the Department of Pathology and Veterinary Diagnostic, Division of Avian Diseases at the Faculty of Veterinary Medicine at the Warsaw University of Life Sciences. The author of nearly 700 academic publications including more than 100 dedicated to pigeon pathology. Studies performed in the field of pathology included the most compelling practical issues, and concerned, among others, paramyxovirosis (the description of the first cases of infection reported in Poland, the development of principles of immunoprophylaxis), therapy against salmonellosis, as well as the prevalence of parasitic diseases and other viral diseases. Professor. Szeleszczuk specializes in the issues of pathology, treatment and immunoprophylaxis of poultry, pet birds and pigeon diseases. His name – as an international expert in the field, is often associated with serodiagnosis of poultry diseases. Also, for several years he has been implementing the project “WAMSER- Warsaw Academy of Applications for Serological Monitoring in Veterinary Epidemiology.” He is the initiator and co-executor of the “Eimeria Avia“project. From the beginning of his career he has been particularly engaged in the issues related to columbopathology. Since nearly 40 years, he continues to perform actions in support of veterinary care for the pigeons in Poland initiated in the early seventies by Professor Wanda Barbara Borzemska. His original initiative, the informal Polish Columbopathologists Club amassed a team of outstanding national experts dealing with the protection of the health of pigeons, who, since 2008, meet regularly at special conferences. For over 10 years he has been the Polish representative in the Scientific Veterinary Comission – Columbophile Federation Internationale.

Dr Colin Walker. Avian Veterinarian

Dr Colin Walker was graduated as a veterinarian from the University of Melbourne in 1979. Through post graduate examination he became a college accrediated avian veterinarian in 2003. He also has a Bachelor of Science majoring in Zoology from the University of Melbourne. Colin worked as a general practitioner veterinarian until 1994 but since that time has focused his veterinary work on birds. Colin established the Knox Bird Veterinary Clinic, later the Melbourne Bird Veterinary Clinic in 2000. Colin has kept pigeons since he was 10 years old and started racing in 1969 when he was 15. He races most years except when work or travel commitments preclude this. Colin competes in his local club, the Knox Racing Pigeon Club and is the club”s president. The Knox Racing Pigeon Club is affiliated with the Victorian Homing Association which has about 300 members. Colin has twice been federation champion (i.e. best flyer for the year) and has twice been runner up. In 2010 he was placed 12th overall. Colin also keeps and exhibits several breeds of fancy pigeons – Nuremburg Lark, Damascene, Australian Suabian, Syrian Tarbesh, and British Show Racers and over the last 10 years has had over 15 National Champions. Colin also maintains 38 aviaries and breeds the less common species of Australian parrots and also Australian Fruit Doves. He believes that maintaining healthy captive populations of these declining birds is a vital part of their conservation. Colin established the Australian Pigeon Company in 1994 which produces a range of pigeon health supplements and medications that are widely used throughout Australia. The active competition of pigeon racing has lost none of it”s excitement for Colin and he remains an ”avian-tragic” being facinated by all things avian. He feels privileged to work with many of the birds that he sees at his clinic and finds being an avian veterinarian enjoyable and rewarding.
