Article summary

An operation with the object of reintroducing the Raven in Belgium has been in progress since 1970. Fifty birds, the majority being yearlings, were released as from 1973, in the South and North-East Ardenne. They all seem to have settled near the releasing sites : each territory includes dense forest, grass-land and a rubbish tip. In 1980, one nest was found on a disused railway viaduct spanning the Semois valley. Three youngs took flight. Moreover, various witnesses state that one case of nidification took place in 1979, but the brood was destroyed. In all probability, this couple formed part of the birds released in 1975, at 5,1 Km from the nesting site. In 1981, this site was again occupied, but the 4 youngs disappeared shortly after hatching, and another nest, containing four eggs, which have been later abandoned as a result of tree-felling, was found in the forest. Various observations lead one to suppose that there were other cases of nidification in 1979, 1980 and 1981, 8 to 10 established pairs being known. This reintroduction would therefore now seem to be heading towards success.
