De 2012 \u00e0 2023, un petit groupe de naturalistes s\u2019est pr\u00e9occup\u00e9 de l\u2019avenir de la chev\u00eache d\u2019Athena<\/strong> en Famenne belge, notamment en pla\u00e7ant des nichoirs<\/strong> . Plus de la moiti\u00e9 de la Famenne est en zone agricole, 40% en couverture foresti\u00e8re, 10% en b\u00e2ti et autres. La Famenne repr\u00e9sente une surface d\u2019environ 1300 km2, dont 700 km2 sont assez favorables \u00e0 cet oiseau : zone agricole \u00ab ouverte \u00ab et semi-bocag\u00e8re, avec des fermes isol\u00e9es. Sur les 328 nichoirs progressivement install\u00e9s<\/strong> en 11 ans, plus de 140 ont \u00e9t\u00e9 occup\u00e9 au moins une fois<\/strong>. Ce sont des nichoirs tr\u00e8s bien con\u00e7us pour \u00e9viter la pr\u00e9dation. En 2023<\/strong>, 109 nichoirs ont \u00e9t\u00e9 occup\u00e9s<\/strong>, soit pr\u00e8s de 1 nichoir sur 3 et les auteurs estiment que cela repr\u00e9sente 73% de la population nicheuse de Chev\u00eaches en Famenne <\/strong>(soit 144 couples\/1300 km2, c\u2019est \u00e0 dire 0,11 couple par km2).<\/p>

\"\"<\/figure>

Au total il y a eu 497 nidifications abouties entre 2012 et 2023, avec 1727 jeunes oiseaux pr\u00eats \u00e0 l\u2019envol<\/strong> observ\u00e9s. Dans la zone d\u2019\u00e9tude, l\u2019effectif nicheur a fortement progress\u00e9, passant de 75 couples en 2012 \u00e0 148 en 2023<\/strong>, alors qu\u2019au niveau de la Wallonie, il a continu\u00e9 de r\u00e9gresser au cours des 15 derni\u00e8res ann\u00e9es ( diminution d\u2019un facteur 2 environ).<\/p>

Cela montre l\u2019utilit\u00e9 des nichoirs pour enrayer la disparition des Chev\u00eaches!<\/p>
