10 Fascinating Facts About the Blue-Capped Motmot

The Blue-capped Motmot, also referred to as the Momotus coeruliceps, is a unique bird species that is found in Central and South America. Known for their vibrant plumage, this bird species is an eye-catcher that has a lot of interesting facts to learn about.

In this article, we will be taking a closer look at the Blue-capped Motmot, including their identification, plumages, and molts.

Identification

One of the most distinctive features of the Blue-capped Motmot is its vibrant blue cap that rests atop its head. The upperparts are green while the underparts are of a cobalt blue and turquoise blue combination.

It has a long, serrated tail, which is deeply indented at the tip. They have a long, down-curved bill that is black, with a yellow base, giving the bird a striking appearance.

The eyes are yellow and have a black mask surrounding them. The bird’s legs and feet are grey.

Field

Identification

When observing Blue-capped Motmot in the field, it is essential to note that they are quite range-specific. They are usually found in the forest borders, second growth, and forest clearings in lowlands and foothills.

They prefer to live in humid and tropical forests and can be observed perching in mid-story or low levels.

Similar Species

One of the Blue-capped Motmot’s close relatives is the Blue-diademed Motmot (Momotus lessonii), which has a similar appearance, except for the blue line that crosses its forehead, instead of the cap. In addition, the turquoise in the bird’s coloration is more pronounced in the Blue-Diademed Motmot’s underparts than in the Blue-capped Motmot.

Plumages

Often, the Blue-capped Motmots’ plumages will show variation across geographical regions. For instance, birds from the northern Amazon tend to have a dark green plumage on the back, while those in the central Amazon have a more olive-green upperpart.

Birds from the southern Amazon have a brighter green plumage. The underparts of the bird, depending on the geographical region, may range from turquoise to a darker blue coloration.

Molts

While molt pattern varies from region to region, observably, the bird appears to change its feathers all at once. This is a phenomenon that can be said to occur because plumage changes in motmots are rapid and in some seasonal context known.

This means that molt happens just once in a year, in most birds. Motmots do not display annual color changes, unlike many species of birds.

Diet and Foraging

Feeding

Blue-capped Motmots mostly hunt for prey while perching and scanning the ground below. When they spot a prey item, they fly down to catch it in mid-air or grab it while remaining on the perch.

Their bills are adapted for killing insects and other prey items. After capturing a prey item, they fly back to the perch, where they manipulate their catch before swallowing it whole.

Diet

The Blue-capped Motmot’s diet comprises mainly insects, arthropods, and small vertebrates, although it may at times feed on berries, fruits, and seeds. Some of their common insect prey items include beetles, ants, termites, caterpillars, grasshoppers, and mantids.

The bird preys on lizards, frogs, and small snakes as their primary vertebrate prey.

Metabolism and Temperature Regulation

Due to their slow metabolism, Blue-capped Motmots are not adapted to high-intensity activities. Their low metabolism requires a steady intake of energy to maintain their body temperature and other bodily functions.

Therefore, the bird feeds for several hours every day. To regulate their body temperature, Blue-capped Motmots may bask in the sun during the morning to increase their body temperature and then rest in the shade during the afternoon to reduce it.

They may also sit with their wings spread to expose their pale undersides, allowing heat to escape more easily.

Sounds and Vocal Behavior

Vocalization

Blue-capped Motmot birds have a variety of vocalizations that they use for communication. The calls of Blue-capped Motmots are relatively low-pitched, mellow, and hollow-sounding.

They use vocalizations to communicate intra-species, especially when mating or establishing territories. The birds have a “keow” call that is most often heard, and which is used as a territorial signaling call.

They also emit a loud “hooah” call, which is mostly used as a contact call or a warning call to alert others of potential predators. During the courtship and breeding season, they produce softer, melodious calls or twittering notes.

Additionally, Blue-capped Motmots also use non-vocal vocalizations such as tail wagging, wing flicking, and rustling of the leaves to communicate with one another.

Conclusion

The Blue-capped Motmot is a fascinating bird and a master of catching prey with its unique bill. It feeds mainly on insects, small vertebrates, and at times, fruits and seeds.

With their slow metabolism requiring steady energy intake, the bird feeds for several hours every day to maintain their body temperature. Meanwhile, the bird’s low-frequency calling vocalizations are used for communication among individuals, mostly for territory establishment, mating, and warning calls.

Understanding the Blue-capped Motmot’s foraging and vocalization behavior provides key insight into their behavior and population dynamics, contributing to effective conservation strategies aimed at preserving the bird in the wild.

Behavior

Locomotion

The Blue-capped Motmot is a perching bird that typically moves about by hopping. When needed, it is capable of quick flights in pursuit of prey or to evade predators.

They fly short distances within their habitat and follow a straight course. When flying, they reveal their bright blue underparts, while their wings reveal a distinctive white patch.

Self Maintenance

Blue-capped Motmots have a unique way of grooming themselves. They take their time grooming their feathers, using their bills to pluck out dirty feathers while smoothing down the rest.

In addition, the bird will rub its bill against a branch or bark to sharpen its mandibles, which can be used for defense or to catch prey.

Agonistic Behavior

Blue-capped Motmots, like many other bird species, exhibit unique behavior when it comes to agonistic encounters. When a territory dispute arises between two rivals, one of the birds is likely to initiate the conflict by flying with an upright stance and an arched back, displaying its impressive headgear feathers.

These feathers serve as a signal to ward off potential competitors and indicate the bird’s dominance.

Sexual Behavior

Blue-capped Motmots mate for life, and their courtship displays include melodious songs and a series of flight displays. The birds will sing back and forth, with each partner taking turns to sing a melodious duet.

During displays, one of the birds will fly and hover with an insect in its bill, making it appear like it is cheating. The partner will respond by chasing the bird with the insect, and the two will engage in a playful interaction.

This behavior is believed to strengthen the bond between the two birds.

Breeding

The Blue-capped Motmot breeds between February and April in Central America and from August to November in South America. The mating process often involves elaborate displays from the male to attract the female.

The pair will engage in mutual preening to establish and reinforce the bond. The female will lay between one to four eggs in a burrow in a riverbank or earthen wall, which they excavate with their bills.

The incubation period lasts for about 3 weeks, and both parents take turns incubating the eggs. After hatching, the chicks are only dependent on their parents for food and protection for six weeks before they fledge.
