Article summary

In the spring 1986, a Bonelli's Warbler (Phylloscopus bonelli) was observed for more than a month on a calcareous slope in the Viroin valley at Treignes (Prov. Namur, belgium). The present article describes this observation and the environment wherein the bird was found. It also gives a synthesis of all Begian observations and two distributional maps. Although the Bonelli's Warbler seems to prefer sunny, slightly forested slopes, this species can also be found in many other forested biotopes in Belgium. Chalkgrasslands in a spontaneous reforested state, which is one of the most interesting characteristics in the landscape of the Viroin valley, forms a very attractive environment for the Bonelli's Warbler. A too intensive clearing of arboreal vegetation in view of botanical improvement, might be disadvantageous for this species. This shows that a thorough botanical and faunistic inventory should always precede any management.
