HUMMINGBIRDS, and the balletic ways in which they feed on flowers, are familiar to most nature enthusiasts.
But they belong to just one of at least 74 bird families that are known, or suspected, to be pollinators.
Relationships between plants and birds first emerged at least 50 million years ago and over time have influenced the evolution of both groups.
This groundbreaking book by Sunderland ecology scientist and all-round naturalist Jeff Ollerton is the first to deal with pollinating birds in all their diversity, involving almost 1,390 avian species interacting with tens of thousands of different plants.
It explores these interactions in all their evolutionary and ecological significance.
Pollinating birds have intricate lives that are often highly dependent on flowers, and the plants themselves are at the whim of birds for their reproduction.
This makes them important players within many ecosystems, including tropical rainforests, dry grasslands, temperate woodlands, coastal mangroves and oceanic islands.
Bird–flower relationships are threatened by disease, habitat destruction and climate change.
Some of the birds are already extinct.
Yet there are optimistic stories to be told about conservation and restoration projects that reveal the commitment of people to preserving these vital ecological connections.
In addition, as a source of cultural inspiration with a history stretching back millennia, pollinating birds and their flowers are part of the ongoing relationship between humanity and the rest of nature.
Birds & Flowers is published by Pelagic Publishing ( https://pelagicpublishing.com/ ) at £19.99.
