Abstract

The effectiveness of tartar emetic in causing forced regurgitation was tested in hooded crow Corvus corone cornix nestlings from a protected area in western Poland Tartar emetic was highly effective in causing regurgitation In 84 of 98 cases 857 nestlings responded by vomiting reflexes producing 81 food samples 826 of all cases After the procedure no bird was observed to develop negative symptoms Survival of the birds subjected to forced regurgitation was higher than in the control group no emetic which is probably related to the administration of glucose to the birds after enforced regurgitation Even repeated administration of tartar emetic was without negative effects on the nestlings The use of tartar emetic does not require frequent visits at the nests limiting the probability of cannibalistic behaviour and nest predationThe author wishes to thank K Wypychowski head of the National Park Ujście Warty for his consent and support of the study Thanks also go to JZ Kosicki L Kuczyński A Skoracka P Czechowski M Czechowska B Gołdyn and Sz Jędrzejewski for their help in field work Iwould further like to thank Romuald Surmacki who sponsored some of the field equipment and Piotr Tryjanowski for advice and discussions The study was performed in conformity with local legal solutions and on consent of the local Ethical Committee NR 58/2003
