Archived 2012-2013 topics: Blue-bellied Parrot (Triclaria malachitacea): request for recent 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 2013. Link to BirdLife species factsheet for Blue-bellied Parrot Blue-bellied Parrot Triclaria malachitacea is currently listed as Near Threatened under criteria A2c,d; A3c,d; A4c,d on the basis that an ongoing population decline of 20-29% over 10 years is suspected to be taking place owing to habitat loss and trapping. Habitat loss has been extensive and is driven by conversion to agriculture, urbanisation, intensive palmito-collecting and cutting for fuelwood (Bencke 1996). In the mid-1980s, small numbers of T. malachitacea were found in international trade, with some internal trade noted, although the species was rarely found in captivity (Bencke 1996). In the early 1990s, the species was considered to number fewer than 5,000 individuals (Lambert et al. 1993); however, an estimate of the total population size has apparently not been made since. Anecdotal evidence from Rio Grande do Sul suggests that, despite Bencke’s (1996) estimation of c.10,000 birds in the state, the species may now be scarce there (J. Gilardi in litt. 2010). Up-to-date information is requested, including estimates of the total population size, the likely rate of decline over 13 years (estimate of three generations) and the severity of threats. Bencke, G.

    This parrot has several current records at the regions of Itajaí Valley, Tijucas Valley as well as Serra do mar region, north of Santa Catarina state, South Brazil. Its preference is for primary or mature secondary growth forests, with good availability of nesting sites (hollow trees) at lowlands and montane regions. Because of change degree in the landscapes of Santa Catarina lowlands, most of recent records of Blue-bellied Parrot at that state are in montane forests regions. Its mainly affected by the reduction and changes in its preferred habitat, as well as the removal of juveniles from the nests for sale. This species is fairly common at large forest fragments in Itajaí Valley, and it seems that couples territory used to be relatively large.

  2. There is a very important comments on Glauco´s concerning the Triclaria behavior:
    – tall forest at slopes foothill in pair. This species do not used to cross large patch of open area.
    -Very territorial why it is easy to catch adult bird with lure bird.
    – There is a Google map , if you select on the subtropical montane valley “forest patch over “arbitrary 5 ha” for a pair. This number of 10.000 seems to me too high. There is not a uniform and so continuous “occupance range”. There is only renmanent “montane foothill valley” of Atlantic forest.
    Please and check Google earth only to feel where to find such kind of “undertory canopy parrot”.

      Many thanks for posting on the T. malachitacea discussion. Could you please leave your name so we can cite your comments if appropriate?

    Blue-bellied Parrot remanins to have a steady population in the Tres Picos State Park in Rio de Janeiro. We have a poperty at 400m in altitude, where we have a small resident population. We bird the area regularly throughout the year, and anywhere at the correct altitude for this species and with the correct habitat of good quality forest up to an altitude of 900m we either see of hear this species regularly. We have noticed no local decline in the past 10 years.
