  • AWI-WL-Hyacinth-Macaw-Comments
    January 27, 2017 VIA Electronic Submission to: http://www.regulations.gov Public Comments Processing Attn: FWS–R9– ES–2012–0013 Division of Policy and Directives Management U.S. Fish and Wildlife Service 4401 N. Fairfax Drive Arlington, VA 22203 Dear Branch Chief Van Norman: Thank you for the opportunity to comment on the proposed threatened listing and draft 4(d) rule for the hyacinth macaw (Anodorhynchus hyacinthinus). These comments are submitted on behalf of the Center for Biological Diversity (Center) and the Animal Welfare Institute (AWI). The Center is a nonprofit conservation organization with more than 1,200,000 members and online activists dedicated to the protection of endangered species and wild places. The Center and its members have a long standing interest in the conservation of foreign species and their habitat, including the hyacinth macaw. AWI is a nonprofit, charitable organization founded in 1951 and dedicated to reducing animal suffering caused by people. AWI has been engaged in efforts to confront issues associated with wildlife trade, particularly the commercial trade in wild-caught birds. We have had a long-standing interest in the conservation of the hyacinth macaw and concern for the detrimental effects of trade coupled with habitat loss on the species. We vehemently disagree with the suggestion that the hyacinth macaw should be listed as threatened instead of endangered under the Endangered Species Act (ESA or Act). Habitat loss is still a significant threat to this species, as is the pet trade. Moreover, the United States Fish and Wildlife Service’s (USFWS or Service) Significant Portion of the Range Policy (SPOR policy) is unlawful as evidenced by the agency’s decision here that the birds are threatened throughout their range and therefore a significant portion of their range need not be analyzed.

A população total com de cerca de 3.000 indivíduos de Arara Azul de vida livre ocorrem principalmente no Pantanal de Mato Grosso, Brasil, uma das maiores áreas alagadas do mundo. Queimadas para a manutenção das pastagens e o tráfico ilegal tem sido e ainda são as maiores ameaças para a sobrevivência da espécie no Pantanal. Nós estudamos as necessidades ambientais, o sucesso reprodutivo e aspectos da biologia reprodutiva da Arara Azul em uma área de 31.000 ha na região norte do Pantanal, de modo a aumentar as informações necessá- rias para elaboração de estratégias de manejo e conservação desta espécie. Procuramos por ninhos, marca- mos e medimos as cavidades dos ninhos e tentamos identificar o potencial de forrageamento e de sítios de nidificação que podem ser colonizados no futuro. Na área de estudo, as Araras Azuis usam cavidades de árvores para nidificar, em árvores entre 10–25 m de altura, a maioria nas bordas de matas. Catorze ninhos foram encontrados (0,045 ninho/100 ha), sendo 12 (85,7%) em apenas uma espécie de árvore, Sterculia ape- tala (Sterculiaceae).

  • Voluntary Intake by Hyacinth Macaws (Anodorhynchus Hyacinthinus)
    VOLUNTARY INTAKE BY HYACINTH MACAWS (ANODORHYNCHUS HYACINTHINUS) María Julieta Olocco Diz, Ing P.A., Nutritionist Nutrition Department, Temaikèn Foundation, Escobar, Buenos Aires, ARGENTINA Abstract In August 2004 two juvenile Hyacinth Macaws (Anodorhynchus hyacinthus) arrived at Temaikèn Wild Animal Park. Their feathers were in very bad condition and they weighed 1,230 g on average. At the very beginning, a diet with a great variety of ingredients was given. Two months later, during a first 5-day period leftovers were measured. At that moment the animals weighed 1,305 g on average. Once it was identified which ingredients were preferred, during a second 14-day period the animals were offered a new high calorie diet in order to improve their weight. After that, a maintenance diet was given twice a day and leftovers were measured again. The diet consumed during this third 5-day period, was 50% water; 16.86% crude protein on Dry Matter Basis (DMB) and 15.39% crude fat (DMB). At this time animals averaged 1333.55 g. At the end of the trial these birds had increased their feed intake from 9% to 13% of their body weight on an as-fed basis. Their feather colour also progressively improved. Introduction The Hyacinth Macaw (Anodorhynchus hyacinthinus) is the biggest parrot in the world. Historically, its distribution included central Brazil, Argentina, Paraguay and Bolivia. In Brazil, the former wide distribution has shrunk to the Pantanal area and small dispersed points. The natural habitat is the Pantanal Biome, which is completely flooded for nearly 5 months. On those soils, groves of Acrocomia sp.

  • Hyacinth Macaw Anodorhynchus Hyacinthinus
    Hyacinth Macaw Anodorhynchus hyacinthinus Class: Aves Order: Psittaciformes Family: Psittacidae Characteristics: Hyacinth (also known as hyacinthia) macaw is the largest species of parrot. Average size is a body length of 100 cm. They are easily recognizable by their brilliant cobalt blue feathers and yellow circling the eye and lower beak. Behavior: Like all macaws, hyacinths have loud, raucous calls that allow them to communicate with each other over long distances, although it has been said to be “less harsh” than the calls of other macaws (IUCN). They prefer to live in dry forests or even in trees in savannah grasslands. Reproduction: Range & Habitat: They nest primarily in pre-existing holes in trees or occasionally cave Lightly forested areas of Brazil, faces in July and December and lay a clutch of two to three eggs which eastern Bolivia and northern incubates for a month. Usually only a single chick will make it to maturity. Paraguay. The chicks will fledge (leave the nest) at around 3 months old but will remain with the parents until around 6 months old (National Aquarium), (Archive). Diet: Wild: Predominately seeds from native palms Zoo: A variety of nuts, primate biscuits and parrot pellets, assorted fruits and vegetables Conservation: Lifespan: up to 60-75 years in Hyacinths are currently classified as vulnerable by the IUCN. Their captivity, 50 years in the wild. declining numbers are due to habitat fragmentation and the illegal pet trade. Throughout the 2000s they were classified as endangered but have Special Adaptations: Their beaks been downlisted to vulnerable as their decline has not been as rapid as can crack some of the hardest nuts previously thought.
