Counted 2025, by Asociación Armonía.

The number for the blue-throated macaw is about 623 to 785 birds: an estimate with a range, counted in 2025 by Asociación Armonía and published in a case study by the Mohamed bin Zayed Species Conservation Fund.
Asociación Armonía's 2025 census puts the wild blue-throated macaw at 623 to 785; savanna fires are a growing threat.
How it was counted
The number is a survey estimate with a range, not a head count: 623 at the low end and 785 at the high end. It counts birds (not pairs or nests) and covers the whole wild population.
An estimate with a range, not a head count: about 623 to 785 birds across the whole wild population.
What moves it
The Mohamed bin Zayed Species Conservation Fund's case study names savanna fires as a returning and growing threat, which Asociación Armonía links to climate change. It also names the trapping of wild birds for illegal trade (largely dealt with, Armonía says) and habitat lost in the past to cattle ranching that was not sustainable.

Who is helping
Asociación Armonía runs a nest-box programme at the Laney Rickman Reserve, where chicks reared in its boxes have fledged.
The next count
The count is repeated about every ten years (systematic censuses 2015 and 2025). No date for the next count is known as of 12 November 2026.
