Index of Conure Species Photos of the Different Conure Species for Identification Conures as Pets Common Health Problems of Conure The subspecies A. They are widespread in wooded hills, mountain slopes at lower elevations, cultivations and gardens.

Jamaican Conures can live in elevations as high as meters ft. They are easily distinguished from other Jamaican parrots by their smaller size, slender body, pointed tail and rapid flight. Outside the breeding season, these conures tend to occur in medium-sized blocks.

Pairs separate from flocks when they are preparing for, and raising, a family. The Aztec Conure Aratinga n. The nominate species, the Jamaican or Orange-throated Conure Aratinga n.

One reason given for the downward trend seen in their population since is deforestation. The bill is horn colored with pale grey at base.

They have white bare eye rings. The eyes are orange. Identification: Smaller than the nominate species described above, but have longer wings. The throat and abdomen are paler brown and they have a smaller bill. Eastern Aztec Conures : Aratinga nana vicinalis Distribution: Northeast Veracruz north to central Tamaulipas, northeast Mexico Identification: Look like the Aztec Conure described above, but with a generally brighter green plumage.

There is less brown on the underparts. Description: Size: They are usually between 9. The tail alone is about 4. Their wingspan is They weigh between 2. Plumage: The Jamaican Conure is primarily green and is well camouflaged in the tropical rainforests where they are found.

This suggest that this color serves as an anti-predation adaptation. Their green coloration allows them to move through the rainforest without being noticed. These conures are green on their head, back and tail. The lower breast and abdomen, the upper breast and the throat are olive-brown; hence the name olive-throated parakeets. The outer webs of the flight feathers are dark blue and the under wing-coverts are dull green.

The underside of the flight feathers are grey. The underside of the tail is olive-yellow. The bare skin around the eye is a cream color. Olive-throated or Jamaican Conures have large horn-colored bills that are curved downward, with visible markings of grey on the base of upper beak and along the sides of lower beak.

Some birds have a few orange feathers around the nostrils. The feet are grey. Males and females look alike. DNA or Surgical Sexing is recommended for breeding birds. Immature Birds: Young birds look like adults but have dark irises brown eyes.

Ecological and Economic Importance: Economic Importance: These conures are popular pets and are considered the most important group in the wildlife trade economically. Aratinga nana are also important for tourism as they attract wildlife enthusiasts that flock to the Caribbean and Tropical areas to see them in their natural habitat. On the downsize, these conures are amongst the most persistant immature-seed predators in the rainforest and make it hard for farmers to harvest crops thoroughly and because of that, they are considered pest Ecological Importance Conures impact their ecosystem as they provide an important mechanism for seed dispersal.

Birds frequently deposit seeds in protected locations provided by trees and shrubs away from areas of intensive animal foraging at the base of fruiting plants. Such protected locations not only increase the probability of seed survival, they generally offer more suitable conditions for seed germination and seedling establishment.

Parrots, though, make it possible for other organisms in their ecological community to eat. Parrots often drop some of the fruits and seeds that they have been collecting. This allows other animals ground foragers to eat. Their calls consist of high-pitched notes; sustained harsh twittering sounds with upward inflection, and piercing chirps.

Males use the contact call for mating. Each bird produced its own unique signature contact call. They eat the buds and fruits of many trees, for example red birch, Erythrina and Spathodea. They may also feed on cultivated crops. Parrot bills have evolved the ability to crush the largest seeds. Their strong bill and muscular tongue allows them to feed on fruits and break seeds that would otherwise be difficult for other animals to crack.

Many plants have built up chemical and mechanical defenses to ward off herbivores. Alternatively, they eat small amounts of toxic seeds and combine them with a larger amount of harmless seeds, therefore substantially decreasing the potential harm.
