A New Stunning Nest Guide Celebrates a Different Aspect of Birding
The Peterson series displays the variety in crafted structures of a whopping 650 species. Co-author David Moskowitz shares insights from the field.
What could possibly contain the color and verve of a Rufous Hummingbird? A Rufous Hummingbird nest, of course. With a cottony interior, finely woven bark shreds, and outer lichen fleck d茅cor, it's just one example of how birds' homes can reflect and enrichen our appreciation of species themselves.
Readers of the , published earlier this year, will be treated to photographs and tips to match that nest, and hundreds of others, with its maker. Nearly 50 years since the renowned series first published a full book about nests, naturalists Casey McFarland, Matthew Monjello, and David Moskowitz are back with a stunning guide that features 650 breeding birds across the continent and 750 photographs of nests. Drawing on their birding expertise and the advances in photography over the last five decades, the resulting guide will encourage beginners and pros alike to cherish this unsung aspect of birding. This guide links bird behavior and evolution with the architecture of nests and highlights vital connections between birds and the habitats where they are born.
爆料公社 recently caught up with co-author David Moskowitz to hear his field stories and insights from the making of this book.
爆料公社: I can imagine some adventures and acrobatics were required for the hundreds of nest photographs featuring design, materials, construction, and habitat in this book. Was there a nest quest that was particularly memorable?
David Moskowitz: The three of us each put in a ton field time to observe as many nests as possible, meet with experts, and recruit photographers who could help extend our efforts. It really added to the quality of the book because it includes the observations of so many different eyes.
But the quest for the picture we have of Varied Thrush nestlings comes to mind. A contributor named Emily Gibson found the nest, which was pretty high in a tree. We had a 10-foot ladder, so I put it up against a neighboring tree to minimize disturbance. When that wasn鈥檛 high enough, I affixed my camera to a 12-foot pole, which could be triggered by an app on my phone. While I balanced at the top of a 10-foot ladder, holding a 12-foot pole over my head, Emily stood on the ground looking through the camera via my phone. After shouting 鈥渁 little left, a little right鈥 for alignment, she captured the image in the perfect moment.
A: What goes through your mind when you first encounter a new bird nest, given how fragile and complex they can be?
DM: If it's an active nest, there's a good chance I found it because I was looking at bird behavior, like hearing nestlings or watching the parents and trying to figure out what鈥檚 happening. During those times, my first concern is to not disturb the birds or the nest, and then to figure out if I can responsibly observe it before leaving the area.
If it鈥檚 an inactive nest out of season, and it鈥檚 one of the species that does not reuse their nests, then I can be more comfortable. But before I go digging too deep into details, I ask about the ecological context first. What鈥檚 the ecosystem? And then, what's the habitat? After that, I finally proceed to the specifics about placement. How is this nest affixed to a branch? Resting on top? Woven? Hanging? I also consider the many structural features, too. What exactly is this nest made from? Are the contents layered? These are all types of clues you鈥檒l need to figure out who made the nest.
(Editor's Note: Before considering photographing a bird's nest, brush up on the do's and don't of ethical nest photography, and 爆料公社's guide to ethical bird photography.)
A: Does encountering a bird nest affect you in ways that seeing or hearing its maker does not?
DM: As somebody who鈥檚 passionate about the ways tracks and sign reveal subtly reveal wildlife at work on this planet, bird nests are gems. An enormous amount of a bird鈥檚 annual and total life energy revolves around the breeding season, so nests distill a bird鈥檚 existence. Seeing birds is wonderful, but seeing a nest means seeing a bird鈥檚 life work, which is magnificent in its own way.
A: These gems have shaped bird evolution, too. How has the nest been a means for bird species to diversify and adapt?
DM: Nests have allowed birds to reproduce in places where the environment was too harsh for young to survive without protection. With nests鈥 insurance against predators and the elements, we can see birds rearing young in precarious places, like behind waterfalls, or on the ground in arctic, jungle, or desert ecosystems. Without nests, birds would have a much more limited range of places to survive. With the diverse techniques and adaptive styles of nest building, birds achieve uber-specialized niches in particular habitats.
A: As human-driven changes to climate and biodiversity pose dire challenges for many bird populations today, how can the vulnerability and resilience we see in nests invite us to better stewardship?
DM: Understanding the specific things that birds need to have successful nests is a helpful precursor to informed conservation choices. My work stems from the idea that building personal relationships with particular species or places helps us to care, and I see this book as an effort to support and inspire those relationships.
For folks doing scientific work, making accurate, non-invasive nest observations will be a good skill to confront the extinction crisis that threatens many birds. But nests seem to spark fascination and discovery within everyone, and that curiosity can drive conservation. Fifty years from now, I hope that people can still go out and find all of these wonderful nests.
