  1. Espèces en péril Two bald eagles perch in a tree. The Department of Natural Resources is reporting the rise of bald eagles in New Brunswick to 110 to 145 breeding pairs from 12 in 1980.(Department of Natural Resources) New Brunswick's endangered bald eagle population is soaring to heights unseen in decades, new estimates from the Department of Natural Resources show. There are between 110 and 145 breeding pairs of the massive bird, known for white feathers on its head and tail. That is double the 66 breeding pairs that were counted in the province a decade ago and a significant boost from the 12 pairs in 1980. Mark McGarrigle, a species at risk biologist at the Department of Natural Resources, said the bald eagle's resurgence is not limited to New Brunswick. "The results are encouraging and positive. We are seeing a positive trend, not just in the province but across North America," McGarrigle said. The Department of Natural Resources will use these new estimates as it identifies ways to help the species recover. The department introduced a new Species at Risk Act in December that increased the number of endangered species to 60 from 16. Under the existing law, the bald eagle is designated on the regionally endangered list because it is not at risk nationally. Now it is being joined by the harlequin duck, peregrine falcon and piping plover as the winged members of the new at-risk list. Most bald eagles can be spotted nesting around freshwater lakes, rivers and estuaries and are often observed soaring overhead with their wingspan that can reach more than two metres. Bald eagle nests are the largest nests of any bird species in North America. 'It is a slow process.'—Mark McGarrigle, provincial biologist The use of pesticides, and in particular DDT, has been blamed for the dramatic reduction of the bald eagle population on the continent.

  2. Qu'est-ce qui se passe à l'pygargues à tête blanche? L'utilisation de pesticides, a été blâmé pour avoir tué la population Pygargue à tête blanche. Déranger les gens de leurs nids ont également été accusés de les tuer. http://www.gnb.ca/0078/speciesatrisk/index-e.asp

  3. Pygargue à tête blanche • Mark McGarrigle, une espèce en biologiste des risques au ministère des Ressources naturelles, a déclaré le retour de l'aigle à tête blanche ne se limite pas au Nouveau-Brunswick. "Les résultats sont encourageants et positifs. Nous assistons à une tendance positive, non seulement dans la province, mais partout en Amérique du Nord," a déclaré McGarrigle

  4. Quand le pygargue à tête blanche trouvé? • En voyant un aigle a été un événement énorme pour la plupart des gens. Pendant Eagles années 1950 et 1960 ont été très peu vu au Nouveau-Brunswick. • Dans le savant début des années 1970 estimait qu'il y avait environ 15 couples d'aigles de nidification dans la province, principalement dans la partie sud-ouest.

  5. Environ ... Combien en reste! • Le ministère des Ressources naturelles est la montée des rapports de pygargues à tête blanche au Nouveau-Brunswick jusqu'à 110 -145 couples reproducteurs à partir de 12 paires en 1980

  6. Lorsque le nid d'aigle à tête blanche! La plupart des pygargues à tête blanche peut être repéré de nidification autour des lacs d'eau douce, et les rivières.
