From pollinating plants to dispersing seeds, birds play a variety of crucial roles that help to keep ecosystems in balance. But when we degrade and fragment their habitats, some species disappear much quicker than others — taking their specific ecosystem functions with them. New research from Papua New Guinea, one of the world’s last havens of intact tropical forest, suggests that forest-specialist insectivores and ground foragers are among the first to go. Given these vulnerable groups of birds include various bird-of-paradise species along with bowerbirds and cassowaries, which are important emblems of PNG, the authors urge conservationists to focus on retaining forest-dependent birds as a strategy that would protect species of both ecological and cultural significance, as well as their forest home. “PNG derives much of its cultural power from birds, as sources of Indigenous clothing, pride as national animals, [or the focus of] ecotourism,” study lead author Krystof Korejs, a zoologist at the University of South Bohemia in the Czech Republic, told Mongabay in an email. Covering the eastern half of the island of New Guinea, PNG is a global epicenter of avian biodiversity. Some of the world’s most ornate and behaviorally complex species are found in its megadiverse old growth rainforests. However, mounting pressure from agricultural expansion and commercial logging are putting stress on these crucial ecosystems, sparking concerns among conservationists about how species will cope.
