There are different species of blue macaws, so the numbers vary depending on which one is meant:

• Spix's Macaw (Little Blue Macaw) : This species was declared extinct in the wild around 2019, with no known wild individuals left at that time. However, thanks to captive breeding programs, the captive population has grown to nearly 200 birds by 2023, with recent reintroduction efforts releasing 52 captive-raised birds back into the wild in 2022. Some wild-born chicks have been recorded since then, but the wild population remains very small and fragile

• Blue-and-yellow Macaw : This species is much more numerous, with about 1 million individuals in captivity worldwide as of 2025. The wild population is not specified here, but it is not considered critically endangered like Spix's macaw

• Blue-throated Macaw : This is the rarest macaw species, with only around 400 to 455 individuals left in the wild. It faces threats from habitat loss, illegal pet trade, and climate change

• The general term "blue macaw" sometimes refers to the Spix's macaw, which according to older IUCN data had about 4,300 individuals left in the wild as of 2016, but this figure is outdated and likely refers to a broader category or includes captive birds. The current status is that Spix's macaw is extinct in the wild but being reintroduced

Summary:

• Spix's Macaw (Little Blue Macaw): Extinct in the wild, about 200 in captivity, 52 reintroduced in 2022, wild population very small.
• Blue-throated Macaw: About 400-455 left in the wild.
• Blue-and-yellow Macaw: Approximately 1 million in captivity, wild population stable.

Therefore, if you mean the Spix's Macaw, the wild population is near zero but increasing slowly due to reintroduction efforts, with about 200 in captivity. If you mean the Blue-throated Macaw, about 400-455 remain in the wild. For Blue-and-yellow Macaws, the population is much larger and not critically endangered
