Cuban macaw

The Cuban macaw (Ara tricolor), also known as the Cuban red macaw, was a species of parrot that inhabited the main island of Cuba and the neighboring Isla de la Juventud. This species is now extinct, with its last reliable sightings occurring in the mid-19th century, likely disappearing by the late 1800s.

Physical Description

At approximately 45–50 cm (18–20 in) in length, the Cuban macaw was one of the smaller macaws. Its plumage was a vibrant mix of colors, featuring a red forehead that faded to orange and then yellow towards the nape. The face, chin, chest, abdomen, and thighs were orange. The upper back displayed reddish-brown feathers tinged with green, while the rump and lower back were blue. Its wing feathers consisted of brown, red, and purplish-blue, and the tail was dark red, darkening to blue at the tip. Distinctive features that set it apart from the scarlet macaw included its smaller size, an all-black beak, and the absence of a yellow shoulder patch.

Habitat and Diet

The natural habitat of the Cuban macaw is believed to have been open savanna with scattered trees, particularly around areas like the Zapata Swamp. Its diet primarily consisted of seeds and fruits, with a noted preference for palm seeds, such as those from the royal palm, and potentially seeds and shoots from the chinaberry tree. The skull structure suggests it consumed hard seeds, similar to larger mainland macaws.

Behavior and Ecology

Little is definitively known about the behavior of the Cuban macaw. Reports indicate it lived in pairs or families and was known to vocalize loudly. Its ability for speech imitation was considered inferior to that of other parrots. Its nesting habits involved utilizing hollows in trees, with a specific mention of nesting in palms. The species was also associated with a unique chewing louse, Psittacobrosus bechsteini, which likely co-extinct with the macaw.

Extinction

The extinction of the Cuban macaw was a result of human activities and environmental pressures. It was hunted by both indigenous peoples and European colonizers for food and for the pet trade. The species was reportedly slow to escape, making it an easy target. Habitat destruction due to the conversion of forests to agriculture also significantly reduced its living space. Furthermore, thousands of individuals were captured and sent to Europe as cagebirds, severely impacting wild populations. Hurricanes, particularly in the mid-19th century, may have also contributed to its demise by fragmenting habitats and scattering remaining populations, making them more vulnerable to hunting.

Taxonomy and Relationships

The precise taxonomic relationship of the Cuban macaw to other macaws was long debated. While it was thought to be closely related to the scarlet macaw, a 2018 DNA study indicated it was the sister species to a group of red and green macaws, diverging from its mainland relatives approximately 4 million years ago. This suggests a long independent evolutionary history on Cuba, with ancestors likely dispersing over open water to reach the Antilles.
