Blue-Throated Macaw 

Ara glaucogularis South America

Also known as caninde macaw.

Blue-throated macaws are often confused with the common Blue & gold macaw. They are similar in color to Blue & gold macaws but have a blue throat rather than the black throat of the Blue & gold they and are smaller. Blue-throated macaws are a brilliant ultramarine blue above (slightly more aqua than a blue & gold) and gold beneath. The naked facial skin patch is white and has rows of blue feathers forming lines. The facial skin blushes with excitement. The tail is long and tapered, blue above and gold beneath.

Macaws are lively boisterous birds and require generous living space. Their beaks are large and strong for opening large nuts (large species). Wild blue- throated macaws are shy and reclusive but hand fed birds are very mischievous, curious and outgoing.

Blue-throated macaws have a tiny range limited to the Bolivian Pantanal, a seasonal flood plain in the Beni province (Northern Bolivia). Biologists only recently observed them for the first time. The wild population is very small. Probably only 100 to 1000 individuals remain in the wild. They inhabit riverine forests and palm groves which form islands of habitat in their grassland habitat. They feed on locally available fruits; especially palm nut fruits, nuts and buds. They nest in cavities especially in dead palm trunks.

Length 34 inches. Weight 700-1000 gm
Life Span – Unknown but probably up to 50 years. Age at maturity – 3-6 years.
Immature birds have dark eyes, which change over time from black to gray to white to yellow. This progression can be used to estimate the age of a macaw.

Macaws are not as long lived as cockatoos. Breeding age is up to approximately 30-35 years. A 40-year-old macaw shows definite signs of aging. A 50-year-old macaw is very old.

Personality - Young hand-raised macaws are very adaptable and typically easily handled by many people. They must be socialized and exposed to a variety of experiences (veterinary visits, other pets, visitors, wing and nail trims, car rides, etc.) at a young age to avoid fearful behavior. Macaws can make excellent pets, especially hyacinths and Blue-throated macaws, although some have a tendency to become nippy. Macaws can be very loud as well as destructive. While some speak, most macaws have limited ability to mimic. Macaws are very intelligent and relatively easy to train. They are a favorite for shows and trick training.

Blue-throated macaws are very inquisitive, mischievous and animated. While they don’t enjoy handling as much as a blue & gold, they are delightful pets and aviary subjects because of their outgoing personalities.

Activities - Macaws are playful and love to chew. They should always be provided with toys, especially wooden blocks that can be chewed, and branches from non-toxic trees. In order to ensure safety companion macaws should not be allowed unsupervised freedom in the home as they often encounter toxins or dangerous items. Young macaws should be socialized to many people and exposed to a variety of situations such as new cages, toys, visits to the veterinarian, handling by friends, wing and nail clips, etc. to avoid fear of novel situations.

Dietary needs - All macaws need plenty of energy for good health. Many of their natural foods, especially palm nuts are rich in oils, and calories.
Macaws should be fed a formulated (pelleted or extruded diet) as a basis for good nutrition. The diet should be supplemented with fresh fruits and vegetables daily to add variety and psychological enrichment. Feed approximately ½ cup of Kaytee Exact. Also offer ½ cup of fresh fruits and vegetables. Give 2-3 nuts as treats. Small amounts of seed may also be given as treats especially as rewards for good behavior. Vitamin supplements are not needed for birds that are eating a formulated diet.

Blue-throated macaws are moderately difficult to hand feed from a very early age. They require a high fat diet and do well with additional protein as well especially at a very young age. Kaytee Exact Macaw handrearing formula is a good choice. A small amount of peanut butter or ground sunflower seeds may be added to increase protein and fat levels. Be careful not to add too much as this will slow digestion.

Identification - All companion and breeding birds should be individually identified to assist in recovery if lost and assist in maintenance of medical and genealogical records. Many breeders apply closed legs bands when chicks are young. While they present a slight risk of entrapment closed bands are preferable to no identification, especially for breeding birds.
Microchips, which can be implanted into the muscle or under the skin, are a reliable means of identification but require electronic readers to verify identification. Tattoos may be used but often fade or become illegible with time. Footprints may have some application in identification.

Grooming - Routine bathing or showering is vital to maintaining good plumage and skin condition. Birds can be misted and allowed to dry in a warm room or in the sun, or dried with a blow drier. An ideal way to bathe macaws is to put them in a cage outside, sprinkle them with the hose, and allow them to dry in the sun. Macaws are strong fliers. Most of the primary flight feathers (10 feathers closest to the tip of the wing) should be clipped to prevent flight. Clip only enough so the bird will glide to the floor.

Sexing - Macaw species show no obvious sexual dimorphism (visual difference between the species) therefore endoscopic examination (Surgical sexing) or laboratory sexing techniques are needed for accurate sex determination. Males are usually larger and have larger heads.

Housing - Macaws are very active and should be provided the largest cage that space and budget allows. Macaws MUST be allowed space to fully extend their wings or muscle atrophy will occur rendering them unable to fly. As macaws are strong chewers, durable cage construction is very important. Many are also adept at opening cage latches. Locks or escape proof latches may be necessary on cages.

Ideally pet macaws should also have a large cage outdoors for bathing and exercise.

Breeding – Blue-throated macaws breed well in captivity. Breeding season is usually in spring and early summer, although some pairs will breed almost year round. Clutch size is usually 2-4 eggs but sometimes more. Incubation period is average 25.5 days (23-27 days). Some additional high fats seeds, like sunflower seed, should be added to the diet during the breeding season to stimulate reproduction. Inexperienced hand feeders should allow the parents to feed for the first few weeks.

Nest Box - Large horizontal wooden boxes (approx. 16”x16”x 36”or 48”) are well accepted by large macaws while some will breed well in a vertical wooden box (approx. 12” x 12” x 36”). Macaws should be provided with plentiful chewing material. Pine shavings make excellent nest box bedding.

Cage size - Macaws must be able to open their wings without touching the sides of their breeding cage (wing span is approximately 3 feet) and should have adequate space to move freely between 2 perches. Example of appropriate suspended cage size for large macaws is 5’ x 5’ x 8’, although larger is better. Cages should be suspended 3-4 feet above the ground.

Cages for large macaws must be constructed of strong wire, which can withstand chewing. Twelve gauge welded wire, 1” x 1” works well for most pairs. Chain link may be needed for pairs that break welded wire caging.
When breeding macaws, noise and proximity to neighbors must be considered.

Mate aggression is uncommon in macaws. Pair bonds are strong but not necessarily life long.

Common diseases and disorders

• Proventricular Dilatation Disease (Macaw wasting disease)
• Feather picking
• Chewing flight and tail feathers by juveniles
• Oral and cloacal papillomas
• Psittacosis (chlamydophila infection)
• Bacterial, viral and fungal infections
• Constricted toe syndrome, chicks
• Beak malformations - chicks
• Pancreatitis
• Allergies, especially to cockatoos
• Kidney Disease - gout
• Toxicity, heavy metal poisoning
  
  Many common health problems of macaws can be prevented by good diet, nutrition and routine health care. Routine veterinary examination (annually) can help you to keep your pet in excellent health and enhance your relationship with your bird.

Conservation status – Critical, exact status unknown– Blue-throated macaws are listed on Appendix I of the Convention on International Trade in Endangered Fauna and Flora. They have a very limited range and are still being trapped for illegal trade. Blue-throated macaws are not common in captivity but breed well and are available in the United States. It is possible that there are more individual birds in captivity than in the wild. International trade requires both import and export permits.
