Pouvant mesurer jusqu\u2019a\u0300 un me\u0300tre d\u2019envergure, c\u2019est la plus grande chauve-souris carnivore connue. Avec ses dents pointues et tranchantes, elle met a\u0300 son menu des oiseaux mais e\u0301galement des mammife\u0300res et des insectes. A de\u0301faut, d\u2019autres chauves-souris lui conviennent parfaitement.<\/p>\n<p>Pour autant, sa voracite\u0301 ne l\u2019empe\u0302che pas d\u2019avoir une vie sociale riche et de\u0301bordante d\u2019affection, comme vient de le montrer une e\u0301tude de scientifiques allemands publie\u0301e dans la revue PLOS One. Une facette largement me\u0301connue, la vie nocturne du mammife\u0300re rendant complexe toute observation.<\/p>\n<p><b>Des chasseurs bien plus sociables qu\u2019on ne le croyait<\/b><\/p>\n<p>Pour contourner cette difficulte\u0301, les chercheurs ont installe\u0301 une came\u0301ra infrarouge sensible aux mouvements a\u0300 l\u2019inte\u0301rieur d\u2019un arbre creux d\u2019une fore\u0302t du Costa Rica ou\u0300 re\u0301sidait une famille de quatre de ces mammife\u0300res.<\/p>\n<p>Il leur a fallu trois mois d\u2019observations intensives pour de\u0301couvrir que ces animaux e\u0301taient bien plus sociables qu\u2019on ne le pensait. Jusqu\u2019alors, les Faux-vampires de Linne\u0301 e\u0301taient conside\u0301re\u0301s comme des chasseurs solitaires. Or, les chercheurs ont pu enregistrer des adultes partant chasser en groupe et revenant ensemble.<\/p>\n<p>En tout, les scientifiques ont identifie\u0301 huit types de comportements diffe\u0301rents parmi lesquels des interactions sociales, des jeux ou du stockage de nourriture. A l\u2019inte\u0301rieur du tronc, il n\u2019e\u0301tait pas rare d\u2019observer les animaux se toiletter ou communiquer par de longues vocalises. Plus e\u0301tonnant encore, les vide\u0301os ont montre\u0301 des se\u0301ances de \u00ab ca\u0302lins \u00bb au cours desquelles un individu enveloppait un autre de ses larges ailes.<\/p>\n<p><b>Des parents attentionne\u0301s et ge\u0301ne\u0301reux<\/b><\/p>\n<p>Lorsqu\u2019une chauve-souris adulte rentrait au bercail, il n\u2019e\u0301tait pas rare qu\u2019elle donne sa nourriture a\u0300 une femelle allaitante ou a\u0300 un plus jeune de la colonie, permettant ainsi a\u0300 ce dernier de passer graduellement du lait maternel a\u0300 une die\u0300te carnivore. En outre, cela exerc\u0327ait le jeune a\u0300 de\u0301velopper ses talents de pre\u0301hension d\u2019une proie animale avant de quitter le nid et de chasser pour de vrai. Un comportement qui sugge\u0300re que les deux parents prennent soin de leur proge\u0301niture, ce qui est relativement rare au sein du re\u0300gne animal.<\/p>\n<p>Bref, une palette d\u2019attitudes inattendues et complexes qui ont re\u0301ve\u0301le\u0301 aux biologistes que ces animaux sont on ne peut plus e\u0301loigne\u0301s de l\u2019image de chasseurs solitaires et asociaux.<\/p>\n<p>Et lorsque vient l\u2019heure de dormir, tous les animaux s\u2019enroulent ensemble, leurs ailes formant une boule collective compacte. Ils restent alors nez a\u0300 nez avec leurs proches.<\/p>\n<p><strong>Pour plus d&rsquo;informations et d&rsquo;analyses sur la <span style=\"color: #ff6600\">Senegal<\/span>, suivez <span style=\"color: #ff6600\">Africa-Press<\/span><\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Africa-Press &#8211; Senegal.
