For our 2025 photo essay we’re celebrating wonderful photos in five themes: the lush, flower-filled habitats of birds in Birdlife in Full Bloom; fun companion shots in Double Vision; the rainbow of birds in Colors of the Bird World; cuteness, vulnerability, and the bonds of family in The Next Generation; wet and wild times in Making a Splash; and an exclusive meet-and-greet with some of the world’s least-seen birds in Rarities. In the final section, we say thank you to all the photographers who make the Macaulay Library archive such a uniquely rich resource.
Birdlife in Full Bloom
The Macaulay Library archive doesn’t just feature birds; many photos capture birds within the context of habitat. When photographers frame birds within colorful flowers, it’s often a chance to record behaviors, too—whether a Ruby-throated Hummingbird sipping from a sage plant, a Fiji Parrotfinch nibbling at blossoms in search of nectar, or a Silvereye melting into a bed of golden wattles, Australia’s national flower.
The vast majority of Macaulay Library photos feature a single bird, but many feature two subjects—such as a pair of Pied Kingfishers in a moment of courtship along the Nile River, or sometimes even a bird and an insect (in this case, a moth alighting atop the head of a Peruvian Racket-tail hummingbird).
Photos in the Macaulay Library archive run across the color spectrum of birds and their habitats, from pink to green to brown to blue, and beyond. The dominant hues in tens of millions of Macaulay Library photos help train the Merlin Bird ID app to identify bird species using people’s perceptions of color. Thousands of generous photographers have empowered Merlin to serve as a global resource to connect people with birds.
The Macaulay Library is full of images that feature bird families, parents and their young. Sometimes photos are contributed by scientists who take a pause from fieldwork to capture a stunning moment, as the intimate glimpse of a female whip-poor-will and its three-day-old chick uploaded by a University of Rhode Island master’s student.
Birds flock to water in search of food and safety, while photographers flock to water for the birds it draws in, and the surprising ways water can bring still photographs to life. A photo of a vagrant Brown Booby in Indiana is all the more valuable to the Macaulay Library when it records an interesting behavior, such as a dog-like head shake following a dive.
The Macaulay Library contains photos of more than 10,000 bird species, yet photographers are continually adding new-to-the-archive species—such as an image of a rarely photographed bush warbler from the remote Indonesian island of Taliabu, and a recently rediscovered sabrewing species in Colombia’s Santa Marta mountains.
The Tachira Antpitta was a “lost species” for many years until recently rediscovered in southern Táchira, Venezuela.

The triller depends on undisturbed forest and is vulnerable to extensive logging operations on the island. Photo by Jonathan Bergmark / Macaulay Library.Snow Bunting in Alaska.

Thank You
A global resource, the Macaulay Library’s collection of natural history media is made possible thanks to the dedication, passion, and generosity of birders around the world. Every photo, video, and audio recording you share deepens our understanding of birds, their behavior, and conservation needs. Your work not only documents the beauty of birds and wildlife, it also serves as an invaluable resource for scientists, educators, and nature enthusiasts around the world. This year’s “Best of Macaulay Library” collection is a celebration of your commitment to capturing the magic of the natural world and sharing it with others.
In 2024, your contributions helped to train a new Merlin Bird ID photo identification model—a feature that helps millions of people around the world identify birds in photos. Media from the archive were used in several scientific studies, from new plumage descriptions, to range revisions, to taxonomic splits. This library, and its growth to over 67 million photos and nearly 2.5 million audio recordings, continues to provide endless inspiration and awe for nature lovers around the world. From all of us at the Macaulay Library and Cornell Lab of Ornithology, thank you for helping share the story of birds and wildlife, one upload at a time.
