7 Fascinating Behaviors of the Critically Endangered Blue-throated Macaw

Birds are one of the most fascinating creatures on the planet, with over 10,000 species worldwide. Each bird species is unique, with its own incredible features and characteristics that set it apart from others.

In this article, we focus on the Blue-throated Macaw (Ara glaucogularis), a critically endangered bird species that can be found in a small region in Bolivia.

Identification

Field Identification

The Blue-throated Macaw has a bright, exotic appearance that makes it easy to identify. It has a blue head, neck, throat, and back, with a yellow chin, chest, and belly.

Its wings are green, and its tail feathers are blue and green with a red base. The bird’s beak is black, and its eyes are yellow-ringed with a dark brown iris.

Similar Species

The Blue-throated Macaw is often mistaken for its relative, the Blue-and-yellow Macaw (Ara ararauna), due to their similar physical features. However, the Blue-throated Macaw can be distinguished by its turquoise-blue throat, which contrasts with the bright yellow chin of the Blue-and-yellow Macaw.

Plumages

The Blue-throated Macaw has only one plumage and does not change color with age, breeding cycle, or season. However, like most birds, it undergoes a molt every year.

Molts

The molting process involves the shedding of old feathers and the growth of new ones. The Blue-throated Macaw undergoes both complete and partial molts, meaning that it sheds all its feathers and only some feathers, respectively.

The complete molt takes place before the breeding season, while the partial molt takes place after the breeding season. During the complete molt, the bird will look scruffy and disheveled, with feathers falling out and new ones emerging.

The molting process can take anywhere from a few weeks to several months, depending on the bird’s age, health, and environmental conditions.

Conclusion

In conclusion, the Blue-throated Macaw is a unique bird species with distinct physical features that set it apart from other macaw species. Although it is endangered, the bird has captured the hearts of many people worldwide, and conservation efforts are continuously ongoing to protect and safeguard its population.

Understanding the Blue-throated Macaw’s identification, plumages, and molts can help bird lovers appreciate the bird’s beauty and uniqueness better.
