Un individu mâle de charme à boutons, ou parfois appelé charme ridé Sulawesi (Rhyticeros cassidix), nourrit une femme avec un fruit de ficus alors qu'elle se nourrit sur un figuier dans une zone de forêt tropicale près du mont Tangkoko et de DuaSudara à Bitung, dans le nord de Sulawesi, en Indonésie. « Les charnons sont des espèces diurnes qui voyagent principalement par paires et restent monogames », a écrit Amanda Hackett de la Wildlife conservation Society dans une publication de 2022. Jouer un rôle important dans la dispersion des graines, souvent surnommé comme agriculteur forestier par des ornithologues, les hornbites « maintiennent le cycle de la forêt en croissance et en évolution ».

A male individual of knobbed hornbill, or sometimes called Sulawesi wrinkled hornbill (Rhyticeros cassidix), feeds a female individual with a ficus fruit as they are foraging on a fig tree in a rainforest area near Mount Tangkoko and DuaSudara in Bitung, North Sulawesi, Indonesia. "Hornbills are diurnal species that mostly travel in pairs and remain monogamous, " wrote Amanda Hackett of Wildlife Conservation Society in a 2022 publication. Play an important role in seed dispersal—often dubbed as forest farmer by ornithologists, hornbills "keep the cycle of the forest growing and evolving with all the fruit they consume each day, " Amanda added._ However, she wrote, the knobbed hornbill is currently considered vulnerable to extinction due to logging and hunting. "With trees diminishing, there are no safe places for hornbill pairs to build their nests in large mature trees, " she added._ A 2016 assessment for The IUCN Red List of Threatened Species has categorized Rhyticeros cassidix as a Vulnerable species._ Due to their dependency on forest and certain types of trees, hornbills in general are threatened also by climate change._ A research conducted by a team of scientists led by Dr. Nicholas Pattinson (University of Cape Town) revealed that there is a connection between warming temperature and the survival rate of the yellow-billed hornbill (Tockus leucomelas)._ "Much of the public perception of the effects of the climate crisis is related to scenarios calculated for 2050 and beyond. Yet the effects of the climate crisis are current and can manifest not just within our lifetime, but even over a single decade, " said Dr. Nicholas Pattinson (University of Cape Town), as quoted by Newsweek on May 5, 2022._ "There is rapidly growing evidence for the negative effects of high temperatures on the behavior, physiology, breeding, and survival of various bird, mammal, and reptile species around the world, " Pattinson added.
