Archived 2014 discussion: Hyacinth Macaw (Anodorhynchus hyacinthinus): request for information

This discussion was first published on Dec 1 2010 as part of the 2010-2011 Red List update, but remains open for comment to enable reassessment in 2014.

Link to BirdLife species factsheet for Hyacinth Macaw

Hyacinth Macaw Anodorhynchus hyacinthinus is currently listed as Endangered under criterion A2c,d because the population has undergone very rapid declines in the past and the threats of illegal trapping for the cagebird trade and habitat loss persist. The rate of past declines has been estimated to be in the range of 50-79% over 45 years (estimate of three generations).

The last population estimate took place in 2003, when it was noted that the populations in east Amazonia and Gerais had declined by around a third since 1986 (Anon. 2004). However, the largest portion of the total population in the Pantanal has shown signs of increasing since 1990 (Pinho and Nogueira 2003, Anon. 2004). It is now unclear whether the population as a whole is still declining at a rate of 50-79% over 45 years. Furthermore, improved knowledge of the species’s life history means that the population trend should be estimated for a period of 31 years (revised estimate of three generations).

Up-to-date population estimates and information on threats and likely population trends are invited to help clarify this species’s current status.

  1. Rob Clay says:

    A small population remains in Concepción department, Paraguay, but at best numbers a handful of birds. Their continued survival depends on the goodwill of private landowners, with trapping continuing to pose a threat. Despite signifficant fieldwork in the Pantanal of Alto Paraguay department, there have been no observations to substantiate reports by local people.

  2. I visited a Pantanal cattle ranch in February 2011 near San Matias in Bolivia to review the site for Hyacinth Macaw Bolivian tourism. Four pairs lived in the area, which were very tame. The local ranchers told me in the dry season there are many more in the area, often flying over from Brazil. They say there are a lot more now, then 15 years ago. There was no interest in trapping, or killing the birds.
    Our illegal pet trade monitoring did not find Hycinth Macaws travelling through on market to Lima, Peru, like outher species. There appears to be almost no illegal trade in Bolivia.

  3. There was a reported sight record of this species in Eastern Colombia
    Ref: Rodriguez–M., J.V. & Hernández–C., J.I. 2002. Loros de Colombia. Conservation International Tropical Field Guide Series. Conservación Internacional Colombia, Bogotá.

    However, it is now considered highly doubtful:

    We did not include it for Colombia in the recent McMullan et al. (2011, 2012) field guides as a result of the latter publication.

    The Colombian record / possible range should be excluded for purposes of distribution assessments until such time (if any) as a confirmed record comes to light.

  4. Nancy López de Kochalka says:

    Durante la ejecución de la Evaluación Ecológica Rápida del Parque Nacional Serranía San Luis, Departamento de Concepción, registré a un solo ejemplar adulto del gua’a hovy (Anodorrhynchus hyacinthinus), el 12 de agosto de 2012. El ejemplar cruzaba desde el norte hacia el sur por la serranía, dominada en ese lugar por el Cerrado y Campos Sucios de Cerrado. Algunos lugareños mencionaron ver a la especie a veces, uno o dos ejemplares. No se sabe cuantos individuos habitan esta porción norte de Concepción. Tampoco existe confirmación certera si anidan en Paraguay, si hay individuos que residen durante el año o solo son migrantes estacionales. No he registrado ningún individuo que esté en comercialización en los últimos 5 años. Sus hábitats predilectos se encuentran seriamente amenazados: el Cerrado (sensu strictu), el Cerradón (sabana arbolada y arbustiva) y las sub facies Campo Sucio de Cerrado, Campo Limpio de Cerrado en asociación con los Bosques Sub Húmedos y Semicaducifolios – Bosques en Galería.

  5. As Rob said the situation of Concepción Department in Paraguay did not change much, despite the absense of records during the lasts trips to the area we believe that the population is still present in low numbers, there are more new human settlements but in the other hand new protected areas were created both private and one govermental owned: Paso Bravo National Park that ranges 100.000 Ha, but unfortunately it suffers from ilegal logging and hunting.
    In respect to Nancy’s comment we have a filmic report on a pair of macaws nesting in a cavity of a Trebol tree in Garay Cue neighbor of San Luis National Park confirming that they nest in the country.
    And the last news is a photo report on 2012 of a pair in the Cerrado area of the dry Chaco confirming the local reports and evidences such feathers and indian’s reports from the area.

    Preliminary proposals

    Based on available information and comments posted above, our preliminary proposal for the 2014 Red List would be to treat Hyacinth Macaw Anodorhynchus hyacinthinus as Vulnerable under criterion A2cd.

    There is now a period for further comments until the final deadline of 31 March, after which recommended categorisations will be put forward to IUCN.

    The final Red List categories will be published on the BirdLife and IUCN websites in mid-2014, following further checking of information relevant to the assessments by both BirdLife and IUCN.

  7. Bennett Hennesey says:

    I conducted a Hyacinth Macaw tourism evaluation in the Pantanal area of Brazil in March 2013 for 3 days. I was impressed with how local wildlife laws were being well enforced in the Pantanal region- the Hyacinth’s habitat. We were told how there is a roosting site over a gas station along the main highway. Local information is that the species is more abundant, tame and well protected in the region. We also saw many Hyacinth Macaws on a ranch, where the owners say the numbers are increasing, and they are tamer.

    Recommended categorisation to be put forward to IUCN

    Following further review, there has been no change to our preliminary proposal for the 2014 Red List status of this species.

    The final categorisation will be published later in 2014, following further checking of information relevant to the assessment by BirdLife and IUCN.
