| Bolivia | Found sporadically |
| North-central Brazil | Inhabited by P. b. sturmii |
| South of the Amazon River in Brazil | Inhabited by P. b. reichenowi |
| Northeastern Brazil | Inhabited by P. b. bitorquatus |
Behavior
The red-necked aracari exhibits various intriguing behaviors in its natural habitat. Let’s delve into some key aspects of their behavior, including movement, feeding habits, and breeding.
Movement
The red-necked aracari is primarily a sedentary species, with limited local movements. They are typically found foraging from the mid-levels to the canopy of the forest. These birds may forage alone, in pairs, or in small groups, navigating the dense foliage with agility and precision.
Feeding
The red-necked aracari has a diverse diet, primarily consisting of fruits. They consume a wide variety of fruits from different trees, playing a crucial role in seed dispersal and forest regeneration. However, their diet is not limited to fruits alone. These aracaris also include insects, eggs, and small vertebrates in their feeding habits, which provide them with essential nutrients for their survival.
Breeding
The breeding season for the red-necked aracari typically spans from February to August in most areas, although this may vary slightly depending on the specific location. While their breeding biology is not well known, it is assumed that they nest in tree cavities, similar to other toucans. These aracaris engage in vocalizations, using various calls and notes as a means of communication within their social groups.
The behavior of the red-necked aracari showcases their adaptability to their environment and the critical role they play in maintaining forest ecosystems through their feeding habits and breeding activities.
Conservation Status
The conservation status of the red-necked aracari varies depending on the region and subspecies. According to the International Union for Conservation of Nature (IUCN), the “western” subspecies Pteroglossus bitorquatus sturmii is classified as Least Concern. Although it has a large range, the population of the “western” subspecies is believed to be decreasing.
On the other hand, the “eastern” subspecies, Pteroglossus bitorquatus reichenowi and Pteroglossus bitorquatus bitorquatus, are classified as Endangered. This conservation status is primarily due to habitat loss caused by deforestation in the Amazon basin.
The red-necked aracari faces continued threats from deforestation, particularly in regions like the Chaco and the Atlantic Forest in Brazil. The destruction of their natural habitat is the main driver behind the declining population of these birds.
To understand the conservation status of the red-necked aracari, it is important to assess the threats they face, their population trends, and the habitats they rely on. This knowledge is crucial in developing effective strategies for their protection and ensuring their long-term survival in the wild.
Human Interaction and Significance
The red-necked aracaris have gained significant attention due to their unique appearance and vibrant plumage, making them highly sought after by birdwatchers and nature enthusiasts. Their striking red neck and colorful feathers make them a fascinating sight in the wild and a popular subject for photography and observation.
Moreover, the red-necked aracaris have economic importance in the field of ecotourism. Their presence attracts tourists to conservation areas, contributing to local economies through birdwatching tours, photography workshops, and guided nature excursions. Many birdwatching enthusiasts specifically visit regions where red-necked aracaris can be found, adding to the local tourism industry.
However, it is important to note that while these birds are admired for their beauty, they are not suitable as pets for most people. Red-necked aracaris require specific care and a suitable environment that replicates their natural habitat. Keeping them as pets can be challenging and requires a deep understanding of their needs and behaviors.
While red-necked aracaris are sometimes traded in the pet industry, it is crucial to approach their capture and trade with caution. Unregulated pet trade can have negative impacts on the wild populations of red-necked aracaris, including habitat destruction, stress on captured individuals, and disruption of natural breeding patterns. It is essential to adopt responsible practices when considering the trade and ownership of these birds.
