Naturaliste du N.-B. en vedette : Le Recensement des oiseaux de No\u00ebl, une longue tradition<\/h2>\n\n\n\n

\u00c9crit par Don MacPhail<\/em><\/p>\n\n\n\n

Le Recensement des oiseaux de No\u00ebl (RON) est le plus ancien projet de science citoyenne d\u2019Am\u00e9rique du Nord. Il a \u00e9t\u00e9 lanc\u00e9 le jour de No\u00ebl 1900 et, \u00e0 9 h ce matin-l\u00e0, un N\u00e9o-Brunswickois, William H. Moore, est devenu le premier recenseur d\u2019oiseaux de No\u00ebl au Canada.<\/p>\n\n\n\n

Au cours des 50 ann\u00e9es suivantes, les \u00ab RON \u00bb (en anglais Christmas Bird Count, ou CBC) au N.-B. ont \u00e9t\u00e9 sporadiques et peu fr\u00e9quents, avec seulement une douzaine au total. Mais depuis 1956, des RON ont lieu partout dans la province, parfois plus de 50 par an.<\/p>\n\n\n\n

Alors, qu\u2019est-ce qu\u2019un recensement des oiseaux de No\u00ebl ? Il s\u2019agit d\u2019un relev\u00e9 de la faune aviaire au sein d\u2019un cercle de 24 kilom\u00e8tres de diam\u00e8tre. De nouveaux cercles de comptage sont cr\u00e9\u00e9s de temps \u00e0 autre et peuvent se situer n\u2019importe o\u00f9 sur le continent am\u00e9ricain, \u00e0 condition qu\u2019ils ne chevauchent pas un autre cercle. De nombreux cercles au Nouveau-Brunswick ont \u00e9t\u00e9 cr\u00e9\u00e9s par des clubs de nature locaux et font l\u2019objet d\u2019un recensement ann\u00e9e apr\u00e8s ann\u00e9e. Aujourd’hui, la portion canadienne du RON est g\u00e9r\u00e9e par Oiseaux Canada.<\/p>\n\n\n\n

Les cercles sont recens\u00e9s sur une seule journ\u00e9e entre le 14 d\u00e9cembre et le 5 janvier, le jour pour chaque cercle \u00e9tant fix\u00e9 par un ou une b\u00e9n\u00e9vole d\u00e9sign\u00e9.e pour la r\u00e9gion. Cette personne, appel\u00e9e \u00ab compilateur \u00bb, coordonne aussi la couverture du cercle entre les participants afin d\u2019\u00e9viter tout double comptage des oiseaux. Elle ou il compile ensuite les r\u00e9sultats de chaque groupe de participants et saisit les donn\u00e9es dans la base de donn\u00e9es g\u00e9r\u00e9e par Oiseaux Canada et Audubon. Ce processus a \u00e9t\u00e9 suivi par pr\u00e8s de 2 700 compilateurs de 21 pays et territoires en 2025.<\/p>\n\n\n\t\t\t\t\t\n\t\t\t\t\t\t\t\t\t\t\t

Les participants font comme William Moore lorsqu\u2019il est sorti de sa ferme de Scotch Lake en 1900. Ils notent le temps pass\u00e9 dehors, la distance parcourue et les conditions m\u00e9t\u00e9orologiques. Et ils comptent les oiseaux. Ils recensent les esp\u00e8ces, mais aussi le nombre d\u2019individus de chaque esp\u00e8ce.<\/p>\n\n\n\n

Pour environ un millier de N\u00e9o-Brunswickois, le RON fait partie de leurs activit\u00e9s saisonni\u00e8res annuelles, une occasion de sortir et d\u2019observer les oiseaux pr\u00e9sents entre amis.<\/p>\n\n\n\n

Chaque ann\u00e9e, il y a des surprises, mais je suis toujours \u00e9tonn\u00e9 de constater que, pendant les jours les plus froids et les plus sombres de l\u2019ann\u00e9e, plus de 100 000 oiseaux de plus de 100 esp\u00e8ces partagent la province avec nous.<\/p>\n\n\n\n

Plus de 40 des cercles de recensement du Nouveau-Brunswick sont surveill\u00e9s depuis 30 ans ou plus. Sept cercles m\u00e8nent des enqu\u00eates depuis au moins 65 ans. Des zones comme la for\u00eat bor\u00e9ale du Mont Carleton sont r\u00e9guli\u00e8rement recens\u00e9es par seulement deux personnes et donnent des r\u00e9sultats tr\u00e8s diff\u00e9rents d\u2019un recensement urbain comme celui de Fredericton, qui pr\u00e9sente des habitats diff\u00e9rents et compte entre 75 et 100 participants. Ces deux zones recensent des oiseaux tr\u00e8s diff\u00e9rents de ceux de l\u2019\u00eele Miscou ou de Grand Manan, mais ces quatre zones m\u00e8nent des relev\u00e9s depuis plus de cinq d\u00e9cennies. Les donn\u00e9es environnementales hivernales \u00e9tant rares et les s\u00e9ries de donn\u00e9es couvrant un demi-si\u00e8cle l\u2019\u00e9tant encore plus, les donn\u00e9es du RON de la province constituent une source unique.<\/p>\n\n\n\n

Nature NB soutient le Recensement des oiseaux de No\u00ebl depuis la cr\u00e9ation de l’organisme. Elle a fait la promotion de ce recensement dans toute la province et, surtout, en publie les r\u00e9sultats sans interruption depuis 1969. Les r\u00e9sultats publi\u00e9s sont tous facilement accessibles sur le site Web de Nature NB. Jusqu\u2019\u00e0 r\u00e9cemment, 75 % de ces r\u00e9sultats n\u2019avaient jamais \u00e9t\u00e9 publi\u00e9s sur Audubon et \u00e9taient enferm\u00e9s dans des fichiers PDF et Excel, mais ils prennent d\u00e9sormais vie dans une base de donn\u00e9es consultable. Les quelque 7 millions d\u2019oiseaux recens\u00e9s jusqu\u2019\u00e0 la fin de 2025 commencent \u00e0 raconter leur histoire.<\/p>\n\n\n\n

Pourquoi ne pas participer au RON 2026 ? Il vous suffit de conna\u00eetre un seul oiseau, notre oiseau provincial qui est souvent pr\u00e9sent \u00e0 tous les CBC de la province : la m\u00e9sange \u00e0 t\u00eate noire. Si vous savez rep\u00e9rer les oiseaux, vous pouvez \u00eatre jumel\u00e9 \u00e0 quelqu\u2019un qui saura les identifier. Et qui sait, vous serez peut-\u00eatre celui ou celle qui rep\u00e9rera notre sept millioni\u00e8me oiseau lors de la prochaine saison du RON. Pour trouver un cercle pr\u00e8s de chez vous et compter les oiseaux, rendez-vous sur le site d’Oiseaux Canada autour du 1er d\u00e9cembre.<\/p>\n\n\n\n
