R\u00e9sum\u00e9<\/strong><\/p>\n

Pour plusieurs auteurs, la Gorgebleue imiterait des stridulations d’orthopt\u00e8res et en particulier de grillons. Les sonagrammes pr\u00e9sent\u00e9s ici sugg\u00e8rent des similitudes de structure entre certains motifs de son chant et la stridulation de trois esp\u00e8ces de grillons. Mais ces images ne permettent toutefois pas de r\u00e9futer d\u00e9finitivement l’hypoth\u00e8se d’une simple convergence sonore entre les \u00e9missions de ces insectes et le chant de la Gorgebleue.<\/p>\n

Summary<\/strong><\/p>\n

For several authors, Bluethroat Luscinia svecica cyanecula<\/em> would imitate orthoptera\u2019s stridulations, in particular Gryllidae<\/em>. Sonagrams presented here suggest similarities between some motives of its song and the stridulations of three Gryllidae<\/em>. However, these pictures don\u2019t absolutely refute the assumption of a sound convergence between the sound emissions of these insects and\u00a0 Bluethroat\u2019s song.<\/p>\n
