One of the earliest records (and one of very few at all) of a Lear's macaw in a public zoo was a dramatic display of "the four blues" including Lear's, glaucous, hyacinth, and Spix's macaws in 1900 at the Berlin Zoo. According to the World Parrot Trust, the Lear's macaw is currently extremely rare in captivity and may live for 60 years, whereas the Animal Ageing and Longevity Database cites the maximum recorded longevity for a captive Lear's macaw at 38.3 years. It is recommended that this parrot be kept in an enclosure of 15 metres in length.
