The Plate-billed Mountain Toucan is primarily found in the western foothills of the Andes, specifically in the regions of western Ecuador and southwestern Colombia. This beautiful bird inhabits the high-altitude forests of these areas, thriving in the humid montane forests and along forest edges.
The habitat of the Plate-billed Mountain Toucan is characterized by an abundance of epiphytes, including bromeliads and mosses. With an average annual rainfall of 14 feet, these high-altitude forests provide a lush and diverse environment for the bird. The canopy height ranges from 6 to 10 meters, offering ample tree cover for shelter and foraging.
The altitudinal range of the Plate-billed Mountain Toucan is between 1600 and 2600 meters above sea level. However, there have been observations of this species at higher elevations of up to 3100 meters in Imbabura, Ecuador.
It is worth noting that the Plate-billed Mountain Toucan shares its altitudinal range with another iconic bird species, the Andean cock-of-the-rock. These two species occupy similar ecological niches within the high-altitude forests of the Andes Mountains.
Behavior and Vocalizations
The behavior and vocalizations of the Plate-billed Mountain Toucan are fascinating aspects of this bird’s life. Known for its social behavior, the toucan often roosts in pairs, families, or small groups within its territory. It displays a cooperative foraging behavior, where individuals gather and feed on fruit-rich trees together.
This species is particularly noteworthy for its vocalizations. Among the mountain toucans, the Plate-billed Mountain Toucan stands out as the most vocal. It engages in duetting, a behavior where males and females produce distinct calls that complement each other harmoniously.
The male Plate-billed Mountain Toucan emits a loud and repeating “tryyyyyyyk” sound, while the female produces a drier and staccato-like “t’t’t’t’t’t’t” noise. Both calls can be heard over long distances – the male’s call acts as a territorial proclamation, while the female’s call serves as a response to the male or as a contact call between individuals.
In addition to these vocalizations, the bird also utters rattles and clicks that are loud enough to resonate over a kilometer away. These unique sounds play a significant role in communication and maintaining social bonds within the group.
Fruit Feeding:
The Plate-billed Mountain Toucan has a primarily frugivorous diet, relying heavily on fruit for sustenance. It plays a vital role in seed dispersal for various plant species, contributing to the ecological health of its habitat.
| Plant Species | Role in Seed Dispersal |
|---|---|
| Mountain understory shrub Faramea affinis | Assists in seed dispersal by consuming the fruit and excreting the seeds in different locations. |
| Palm Prestoea acuminata | Contributes to seed distribution by feeding on the palm’s fruits and dispersing the seeds after digestion. |

Breeding and Reproduction
The Plate-billed Mountain Toucan engages in breeding and reproduction during its designated season, which spans from March to October. The peak period for breeding occurs between May and August. During this time, the toucans build their nests in tree cavities, positioning them at heights of up to 30 meters above the ground.
Each clutch typically contains 2 or 3 white eggs, which are diligently incubated by both parents. The incubation period lasts for approximately 16 days, during which the parents take turns keeping the eggs warm and protected.
After the eggs hatch, the young toucans remain in the nest for an average of 46 to 60 days. This prolonged period allows the fledglings to gain strength and develop the necessary skills for survival. Once they are ready, the juveniles take their first flight and fledge from the nest, marking the beginning of their independent journeys in the forest.
It is worth noting that some toucan pairs may rear a second brood after the successful fledging of their first round of offspring. This further contributes to the perpetuation of the Plate-billed Mountain Toucan population.
Summary
The breeding and reproduction process of Plate-billed Mountain Toucans is a fascinating natural event that takes place within the specified breeding season. From nest-building to incubation, fledging, and potentially rearing a second brood, these birds showcase remarkable parental care and adaptability. These processes play a crucial role in ensuring the survival and continuation of this unique toucan species.
Conservation Status and Threats
The Plate-billed Mountain Toucan is classified as Near Threatened on the IUCN Red List due to several factors. This species is experiencing habitat loss and fragmentation as a result of deforestation, particularly for agricultural purposes. The bird’s high-altitude forest habitat is being converted into farmland, which negatively affects its population. In addition to habitat loss, the Plate-billed Mountain Toucan is also impacted by illegal trade as it is sought after as an exotic bird.
Conservation efforts are in place to protect this species, and it is considered the flagship bird of the La Planada Nature Reserve in Colombia.
| Threats to Plate-billed Mountain Toucan | Conservation Efforts |
|---|---|
| 1. Habitat loss and fragmentation due to deforestation | – Establishment of protected areas – Reforestation initiatives |
| 2. Illegal trade for the exotic bird market | – Improvement of law enforcement to combat wildlife trafficking – Public awareness campaigns on the importance of protecting the species |
Conclusion
In conclusion, the Plate-billed Mountain Toucan (Andigena laminirostris) is a captivating bird species that inhabits the high-altitude forests of the Andes in Ecuador and Colombia. Known for its unique features, including its striking plumage, large bill, and zygodactyl toes, this toucan is a sight to behold in its natural habitat.
However, the Plate-billed Mountain Toucan faces significant threats to its survival. Habitat loss, primarily due to deforestation for agricultural purposes, poses a significant risk to the species.
