Le h\u00e9risson \u00e0 titre priv\u00e9 \u2013 un portrait <\/strong><\/h1>\n

 <\/p>\n

Il existe 2 esp\u00e8ces de h\u00e9rissons en Europe. Au Luxembourg, nous ne retrouvons que l\u2018esp\u00e8ce du H\u00e9risson commun (ou ordinaire), aussi appel\u00e9 H\u00e9risson d\u2019Europe occidentale (Erinaceus europaeus L.). Le H\u00e9risson des Balkans ou H\u00e9risson de Roumanie (Erinaceus roumanicus) n\u2019existe qu\u2019en Europe centrale.<\/p>\n

L\u2019esp\u00e8ce indig\u00e8ne au manteau de piquants est un animal solitaire qui a une pr\u00e9dilection pour les jardins \u00e9cologiques, les vergers, les parcs ou encore les haies et les lisi\u00e8res de for\u00eats.<\/p>\n

Comment vit le \u00ab\u00a0K\u00e9isecker\u00a0\u00bb et de quoi se nourrit-il\u00a0?<\/strong><\/h2>\n

\"\"<\/p>\n

Un h\u00e9risson pouvant s\u2019\u00e9panouir en pleine libert\u00e9 peut vivre jusqu\u2019\u00e0 l\u2019\u00e2ge de 7 ans (la moyenne d\u2019\u00e2ge \u00e9tant de 2 \u00e0 4 ans). Difficile \u00e0 surprendre, le h\u00e9risson ne sort qu\u2019\u00e0 la tomb\u00e9e du jour et vit la nuit. Sa vue est faible, mais son odorat est particuli\u00e8rement bien d\u00e9velopp\u00e9.
\nTr\u00e8s friand, son menu est compos\u00e9 principalement de lima\u00e7ons, de vers de terre et de col\u00e9opt\u00e8res, de perce-oreilles ou de cloportes.
\nLe h\u00e9risson chasse sa proie en reniflant sans cesse, et engloutit son repas tout en mastiquant bruyamment.<\/p>\n

Un h\u00e9risson mastiquant :<\/em><\/sup><\/p>\n

 <\/p>\n

Qu\u2019en est-il de la reproduction chez le h\u00e9risson\u00a0?<\/strong><\/h2>\n

https:\/\/www.youtube.com\/watch?v=BYOwD-Tu-Jk<\/a><\/p>\n

Le h\u00e9risson est sexuellement actif (gare aux piquants \u2026\u00a0!) de mai \u00e0 ao\u00fbt\u00a0; au bout d\u2019un mois apr\u00e8s l\u2019accouplement, la femelle accouche d\u2019une port\u00e9e qui est g\u00e9n\u00e9ralement compos\u00e9e de 3 \u00e0 5 petits, qui naissent aveugles. Les jeunes restent avec la m\u00e8re pendant un mois et demi. En automne, le h\u00e9risson se gave pour constituer des r\u00e9serves \u2026 dont il aura besoin puisque la p\u00e9riode d\u2019hibernation durera de novembre \u00e0 fin mars.<\/p>\n

D\u2019o\u00f9 vient ce syst\u00e8me de d\u00e9fense remarquable du h\u00e9risson\u00a0? <\/strong><\/h2>\n

\"\"<\/p>\n

Le h\u00e9risson se caract\u00e9rise par un ensemble de 6.000 \u00e0 8.000 piquants, qui \u2013 du point de vue biologique \u2013 sont des \u00ab\u00a0cheveux\u00a0\u00bb fortifi\u00e9s de k\u00e9ratine, qui lui permettent de se d\u00e9fendre contre des pr\u00e9dateurs naturels tels que fouines et renards.<\/p>\n

Malheureusement, son manteau de piquants ne poss\u00e8de pas les vertus suffisantes pour chasser le blaireau, dot\u00e9, lui, de pattes fortes qui l\u2019habilitent \u00e0 d\u00e9rouler carr\u00e9ment un h\u00e9risson en position de d\u00e9fense, soit en \u00ab\u00a0pelote d\u2019\u00e9chardes\u00a0\u00bb. De m\u00eame, l\u2019armure du h\u00e9risson ne prot\u00e8ge pas suffisamment contre les longues griffes d\u2019un hibou. Cet ennemi de taille peut litt\u00e9ralement d\u00e9pouiller le h\u00e9risson, ne laissant plus que les piquants.[\/vc_column_text][\/vc_column][\/vc_row]<\/p>\n<\/div><\/section>","protected":false},"excerpt":{"rendered":"
