The Yellow-collareds are amongst the largest of all mini macaws. From head to tail, they measure about 14.96 - 15.75 inches (38 cm - 40 cm) of which about half are the long tail feathers; and they weigh 8.8 - 9.9 oz (250 - 280 grams).
The plumage is mostly green, except for some blue, maroon and yellow markings. They were named for their most notable feature - the yellow collar stretching round the back of the neck; the color of which increases in brightness and width with age.
The front and crown is brownish black. The characteristic bare facial skin is white with dark feather tracks below their eyes.
Some of the outer wing feathers are bluish, and the upper portion of the tail feathers are green, blue and the bottom half are wine / maroon colored.
The legs and feet are pale yellowish. The eyes (irises) are orange.
Males and females look alike.
Golden-collared or Yellow-collared Macaw Diet / Feeding
These birds feed on various seeds, nuts, fruits and green food. Most likely, there are some insects in the mix, too, particularly when raising young.
They will also visit clay licks, where they ingest mineral-rich clay. This clay offers valuable protection against toxins naturally found in their diet.
