Difference between revisions of "Indigo Macaw" - BirdForum Opus

Line 11: Line 11:
 
[[Hyacinth Macaw]] and the likely extinct [[Glaucous Macaw]] are the most similar. Smaller than Hyacinth (around 3/4 the size), with a relatively smaller bill. However, Indigo's wings are longer and its wing beats deeper. The yellow face patch differs: in Indigo Macaw it extends away from the mouth in an arc or teardrop shape. In Hyacinth the yellow largely follows the (vertical) lower jaw line as a border and doesn't extend outwards as a patch. Indigo generally shows a whitish inner eye ring which Hyacinth lacks. The intensity of colour differs between the two with Hyacinth more richly coloured. Indigo is paler and more greenish. This is especially apparent on its head.

Similar Species

Hyacinth Macaw and the likely extinct Glaucous Macaw are the most similar. Smaller than Hyacinth (around 3/4 the size), with a relatively smaller bill. However, Indigo's wings are longer and its wing beats deeper. The yellow face patch differs: in Indigo Macaw it extends away from the mouth in an arc or teardrop shape. In Hyacinth the yellow largely follows the (vertical) lower jaw line as a border and doesn't extend outwards as a patch. Indigo generally shows a whitish inner eye ring which Hyacinth lacks. The intensity of colour differs between the two with Hyacinth more richly coloured. Indigo is paler and more greenish. This is especially apparent on its head.

Distribution

South America: found only in eastern Brazil (northern Bahia).

On the verge of extinction; current population estimates are about 4-500 birds. Habitat encroachment by farmers and trapping for the pet trade are significant threats.
