The world of birds is a vast and diverse one, with over 10,000 species that inhabit every corner of the globe. Each species is unique and fascinating, with its own set of characteristics and behaviors that make it stand out.

One such species is the Buckley’s Forest-Falcon, also known as Micrastur buckleyi. In this article, we will explore this incredible bird species, starting with its field identification and how to distinguish it from other similar species.

Identification

Field Identification

The Buckley’s Forest-Falcon is a medium-sized bird of prey, measuring around 15-17 inches in length. It has a dark brown back and wings, with a paler brown or buff-colored breast and belly.

Its head is dark brown, with a distinctive white eyebrow stripe that extends from the bill to just behind the eye. The bill is hooked and dark in color, while the eyes are large and yellow.

Its legs and feet are yellow or orange. One of the most striking features of this species is its broad, rounded tail, which has black and white bars.

Similar Species

The Buckley’s Forest-Falcon is similar in appearance to other forest-dwelling falcons such as the Collared Forest-Falcon and Slaty-backed Forest-Falcon. However, it can be distinguished by its white eyebrow stripe, which is absent in the Collared Forest-Falcon, and its broader tail, which is more squared off than the Slaty-backed Forest-Falcon.

Additionally, the Buckley’s Forest-Falcon has a more uniform dark brown coloration on its wings, while the Slaty-backed Forest-Falcon has distinct, contrasting black and gray wing feathers.

Plumages

The plumage of the Buckley’s Forest-Falcon is relatively consistent throughout its range, with little variation in coloration between individuals or regions. The adult plumage is similar to the juvenile plumage, with the only difference being that the juveniles have a paler breast and belly.

The plumage is replaced gradually over time, with the bird molting some feathers while retaining others. Molting can occur at any time of the year, with some birds molting twice per year.

The process takes several weeks, during which the bird’s feathers become dull and ragged before new ones grow in.

Molts

The Buckley’s Forest-Falcon has two types of molts: the pre-basic molt and the pre-alternate molt. The pre-basic molt, which occurs after the breeding season, involves the replacement of all the bird’s feathers.

This molt can take up to two months, during which the bird cannot fly well and is susceptible to predators. The pre-alternate molt, which occurs after breeding and before migration, involves the replacement of some of the bird’s feathers.

This molt is faster, taking only a few weeks, and allows the bird to maintain its flying ability while still growing in new feathers. In conclusion, the Buckley’s Forest-Falcon is a fascinating bird species that showcases the vast diversity of avian life.

Its distinctive white eyebrow stripe and broad tail make it easy to identify in the field, while its plumage molts provide insight into the bird’s life cycle.
