Dwarf Hyacinth Macaws Identified In Brazilian Pantanal Birdguides In the vast pantanal wetlands of west central brazil, hyacinth macaws substantially smaller than the typical size have been hiding in plain sight. a new species has not been discovered, but rather these are downsized versions of the same species, termed 'dwarf' hyacinth macaws by researchers. 'downsized' hyacinth macaws have been lurking. A casual observer of a hyacinth macaw in flight will likely not have had the chance to observe one at the chick stage, when hatchlings spend three and a half months under the watchful care of their parents before they are ready to leave the nest and gain the skies. a study led by brazilian researchers in the pantanal and, at a smaller scale, in the cerrado (wooded savanna biome), mapped out.
Dwarf Hyacinth Macaws Identified In Brazilian Pantanal Birdguides Here, data collected over 30 years were used to determine growth model of hyacinth macaw (anodorhynchus hyacinthinus) chicks in the pantanal biome of brazil. during this period, the speed of. The total of 162 individuals compares well with the 134 and 107 reported in 2007 and 2011 respectively. the density (individuals sq km) of hyacinth macaws in the bolivian pantanal seems to be almost three times lower than that of brazil, although it is not clear why this should be. in bolivia the key tree species for hyacinth macaw are sujo.

The best fitting growth curves were identified using akaike's information criterion. the best models were the cubic polynomial for body mass, richards for total length, and gompertz for tail length. we confirmed the occurrence of dwarf individuals, whose body mass, total length, and tail length were 20%, 22%, and 70% smaller, respectively, than. Materials and methods procedures. in 2014 three hyacinth macaws were found by a landowner who is also a veterinarian, from a remote farm in the pantanal of rio negro, mato grosso do sul, brazil.
