Mark Brazil reports on the conservation of the rare Lear's Macaw.

While generally easily recognized, it can be confused with the far rarer and smaller Lear's Macaw.

Those groves are vital to the Lear's Macaw.

Licuri palm nuts are the main food source of the Lear's Macaw, making up around 95% of their diet.

S. coronata nuts are the favored food of Lear's Macaw, whose bill size and shape are particularly adapted to crack them.

(Sick's remark was in the context of an article on Lear's Macaw, a larger blue macaw.

The Lear's Macaw's rate of reproduction is 1-2 eggs per year during their mating season from December to May.

However, this idea was soon abandoned, as both plumage, size, and proportions of the Lear's Macaw differ from those of its close relatives.

The Lear's Macaw inhabits stands of Licuri palm.

Lear's Macaw was first described by French ornithologist Charles Lucien Bonaparte in 1856.

All present Lear's Macaw conservation projects are managed under the authority of IBAMA.

While blue macaws have been known from taxidermic and captive specimens since at least 1790, location of the Lear's Macaw's endemic habitat wasn't known until 1978.

Both Hyacinth and Lear's macaws are listed on CITES Appendix 1.

Some recent commentators have suggested that the allopatric Lear's Macaw and Glaucous Macaw should be considered conspecifics.

It is closely related to the Lear's Macaw A. leari and the Hyacinth Macaw A. hyacinthinus.

Glaucous and Lear's macaws are exclusively cliff nesters; Hyacinth macaws are mostly tree nesters.

The Lear's Macaw is similar to the larger Hyacinth macaw and the slightly smaller Glaucous Macaw.

Furthermore, the more robust shaft of the femur sets it specifically apart from the Lear's Macaw while the tibiotarsus is more robust with a flared distal extremity.

Olson and Máiz López showed that the Saint Croix Macaw is within the same size range as the Blue-throated Macaw and the Lear's Macaw.

The length of the tibiotarsus is shorter than in the Blue-throated Macaw but longer than in the Lear's Macaw, while the lengths of the coracoid, carpometacarpus, and femur are smaller.

It includes two endangered species, the Hyacinth Macaw and Lear's Macaw also known as the Indigo Macaw, and one probably extinct species, the Glaucous Macaw.

Its bones are distinct from Amazon parrots as well as from the other medium-sized but geographically distant Lear's Macaw (Anodorhynchus leari) and Blue-throated Macaw (Ara glaucogularis).

The Spix is one of the "four blues", the four species of all blue macaws formerly seen in captivity together including the Hyacinth Macaw, Lear's Macaw, and Glaucous Macaw (extinct).

The Lear's Macaw (Anodorhynchus leari), also known as the Indigo Macaw, is a large all blue Brazilian parrot, a member of a large group of Neotropical parrots known as macaws.
