Blue-and-yellow Macaw

About

The Blue-and-yellow Macaw, also known as the Blue-and-gold Macaw, is a large South American parrot with vibrant blue upperparts and rich golden-yellow underparts. It is a highly intelligent and social bird, often seen in pairs or small family groups, and is well-known for its loud vocalizations and strong, hooked beak.

Physical characteristics

Plumage

Dorsal side (back, wings, tail) is brilliant azure blue. Ventral side (chest, belly, underwings) is rich golden-yellow. The forehead and crown are often tinged with green. A prominent black throat patch extends to the sides of the face, which is bare white skin with fine lines of small black feathers forming a distinctive pattern.

Beak shape

Large, powerful, and sharply hooked, dark grey to black in color. The upper mandible is significantly larger and curves over the lower mandible.

Eye color

Pale yellow to whitish iris in adults, darker in juveniles.

Leg color

Dark grey to black, zygodactyl feet (two toes pointing forward, two backward).

Distinguishing features

The bare white facial patch with black feather lines is a key identifier. The contrast between the bright blue upperparts and golden-yellow underparts is unmistakable. The long, tapering blue tail with golden-yellow undertail coverts is also characteristic.

Juvenile appearance

Juveniles resemble adults but have a darker iris (brownish-grey) and a shorter tail. Their plumage may appear slightly duller, and the black feather lines on the facial patch may be less defined.

Seasonal changes

No significant seasonal changes in plumage. Plumage remains consistent year-round.

Sexual dimorphism

Minimal to none. Males and females are outwardly identical in plumage and size. Sexing typically requires DNA testing or surgical sexing.

How to identify

1. 1

   Plumage Coloration

   Look for the striking combination of bright blue upperparts and golden-yellow underparts. This is the most definitive field mark.

2. 2

   Facial Patch

   Observe the bare white facial skin with distinct lines of small black feathers. This pattern is unique to the species among the large macaws.

3. 3

   Size and Shape

   Its large size (up to 86 cm) and long, tapering tail are characteristic. The powerful, dark, hooked beak is also prominent.

4. 4

   Vocalizations

   Listen for their loud, harsh, and guttural calls, especially when they are flying overhead or in groups.

5. 5

   Flight Pattern

   Note their strong, direct flight with powerful wing beats, often in pairs or small groups, making them conspicuous.

Habitat & range

Biomes

Tropical and subtropical rainforests, gallery forests, savannas with scattered trees, palm groves, and open woodlands.

Geographic range

South America, from eastern Panama south through Colombia, Venezuela, the Guianas, Ecuador, Peru, Bolivia, and Brazil, extending into northern Paraguay and northeastern Argentina. Absent from the western Andes.

Elevation range

Typically found from sea level up to 500 meters (1,640 feet), occasionally higher.

Preferred environments

Prefers areas near water, such as rivers, swamps, and flooded forests, where palm trees and other fruit-bearing trees are abundant. Also found in disturbed areas and agricultural lands adjacent to forests.

Behavior

Activity time

Diurnal. Most active during the early morning and late afternoon, foraging and socializing. They roost communally in large trees at night.

Feeding habits

Feeds primarily on a variety of fruits, nuts, seeds, and berries. They have a powerful beak capable of cracking hard nuts, including palm nuts. They also consume clay from riverbanks (geophagy), which is thought to neutralize toxins from their diet and provide essential minerals.

Social behavior

Highly social birds, typically seen in pairs or small family groups. They often gather in larger flocks at communal roosting sites or feeding areas. They are monogamous and form strong pair bonds.

Flight pattern

Strong, direct, and often high-flying. They fly with powerful, shallow wing beats, often in pairs or small groups, making loud calls. Their long tails are prominent in flight.

Migration pattern

Generally resident throughout their range, with some local movements in response to food availability. Not considered a migratory species.

Territoriality

Pairs defend their nesting sites during the breeding season, but outside of this period, they are less territorial, often foraging and roosting communally.

Breeding & reproduction

Breeding season

Varies geographically, but generally from November to April in the southern parts of its range and February to June in the northern parts.

Nesting habits

Nests almost exclusively in tree cavities, particularly in dead palm trees (e.g., Mauritia flexuosa). They do not construct a nest but lay eggs directly on the bottom of the cavity.

Clutch size

1-3 eggs, most commonly 2.

Egg description

Typically 2-3 dull white, oval eggs.

Incubation period

Approximately 25-28 days, primarily by the female.

Fledging period

Chicks fledge (leave the nest) at about 90-100 days old. They remain dependent on their parents for several months after fledging.

Parental care

Both parents participate in feeding the chicks. The male often feeds the female during incubation. After fledging, the young birds stay with their parents for an extended period, learning foraging skills and social behaviors.

Where to find

Field tips

1. Listen for Calls. Their loud vocalizations often give away their presence before they are seen. Listen for their distinctive 'scree-onk' calls.
2. Look for Pairs or Flocks. They are rarely solitary. Scan the skies or tree canopy for pairs or small groups, especially at dawn and dusk.
3. Observe Roosting Sites. They often gather in large communal roosts in tall trees at dusk. Locating a roost can provide excellent viewing opportunities.
4. Check Clay Licks. In some regions, macaws visit clay licks (collpas) to ingest minerals. These are prime locations for observation, especially in the early morning.
5. Focus on Food Sources. Look for them in trees bearing ripe fruits, nuts, or seeds, particularly palm trees.

Fun facts

• Blue-and-yellow Macaws are known for their strong pair bonds, often remaining with the same mate for life.
• Their powerful beaks can crack open extremely hard nuts, including Brazil nuts, which are too tough for many other animals.
• They are highly intelligent and can be taught to mimic human speech and perform tricks, making them popular as pets, though their care requirements are extensive.
• The bare facial patch with black feather lines is unique to each individual, much like a human fingerprint.
• They play an important ecological role as seed dispersers, helping to regenerate tropical forests.
