Answer:
Might be a little extreme to say that we’d be wading knee-deep in invertebrates if birds disappeared – but maybe not that extreme. A recent study has shown that birds eat 400-500 million tons of insects a year. In China, two-thirds of the diet of House Swift Apus nipalensis consists of agricultural pests, and in forests across the Americas, Evening Grosbeak Hesperiphona vespertina becomes a superhero during outbreaks of Spruce Budworm, providing biological control worth $1,820 per square kilometre. Birds are so efficient that nest boxes have become a pest control practice throughout Europe.
When we think pollinators, bees and butterflies flutter to mind – but bird pollinators such as hummingbirds and honeyeaters also make a big contribution, especially in high altitudes or hot climates. In South Africa, for instance, nearly a quarter of Salvia species are bird-pollinated. Such flowers are lacking in scent, since birds favour sight over smell. Their role as pollinators benefits us directly – around 5% of the plants humans use for food or medicine are pollinated by birds. And when they disappear, the results can be drastic: 31 species of Hawaiian bellflowers appear to have gone extinct along with the birds that pollinated them.
The sight of vultures circling overhead may look foreboding, but it is both their speed of arrival (typically within an hour of death), and their thoroughness which makes them so valuable. It could be days before other less efficient scavengers, such as feral dogs or rats, arrive to pick at the remains, allowing deadly diseases such as rabies and tuberculosis to develop and spread. Over its lifetime, a single vulture provides waste disposal services worth around US$11,600. Following the collapse of Asia’s vultures, India’s feral dog population surged by 5.5 million, spreading rabies and leading to an estimated 47,300 human deaths.
