Blue-and-yellow macaws can live from 30 to 35 years in the wild, and reach sexual maturity between the ages of 3 and 6 years. [7] Little variation in plumage is seen across the range. Some birds have a more orange or "butterscotch" underside color, particularly on the breast. This was often seen in Trinidad birds and others of the Caribbean area.
Wild species may forage widely, over 100 km (62 mi) for some of the larger species such as Ara araurana (blue and yellow macaw) and Ara ambigua (great green macaw), in search of seasonally available foods. Some foods eaten by macaws in certain regions in the wild are said to contain toxic or caustic substances
Blue-throated macaw (Ara glaucogularis) 75–85 cm (30–34 in) long. Blue upperparts and mostly yellow lowerparts, blue throat. Areas of pale skin on the sides of the face are covered with lines of small dark-blue feathers, with pinkish bare skin at the base of the beak. [11] North Bolivia Scarlet macaw (Ara macao) 81–96 cm (32–36 in) long.
Well, yes, the blue-and-gold macaw has a rather long lifespan, most only live about 70 years though, more or less depening on if they live in captivity, or the wild. Considering you're question, I dont know if a b&g macaw ever lived 100 years, I have never heard of it, although they can live a long time, 100 years seems like a strech to me.
Military macaws measure from 70 to 85 centimeters (28 to 33 inches) long on-average, with a 99–110 cm (39–43 in) wingspan. The birds are mostly green-plumed, with light-blue and yellow flight and tail feathers, and a bright-red patch on the forehead. Their face is bare, as with most macaws, being whitish in colour with black striations.
Two years later, 20 Spix’s macaws were released in the wild, along with 15 wild-sourced Blue-Winged macaws, whose purpose was to “teach” them how to fly, avoid risks and forage. Last year ...
A second genus is extinct in the wild. Over a third of the extant species are classified as threatened by the IUCN. A few of these are in imminent danger of extinction with fewer than 500 individuals in the wild or in captivity: glaucous macaw, Spix's macaw, blue-throated macaw, Puerto Rican parrot, and indigo-winged parrot.
In the wild the blue-throated macaw often compete for nesting-holes in trees with the blue-and-yellow macaw, green-winged macaw, scarlet macaw, woodpeckers, toco toucans, barn owls, bats, and bees. [10] The number of suitable nest trees has been in decline due to the large amounts of deforestation in its natural habitat. [8]
