North American bird populations are plummeting, especially in drylands, grasslands and the Arctic where they have historically been most abundant, new research has found.
The analysis of almost 500 species of North American birds indicates that three out of four species are suffering declines across their ranges, with two in three shrinking significantly.
“We’re not just seeing small shifts happening — we’re documenting populations declining where they were once really abundant,” said lead author of the paper Alison Johnston, an ecological statistician who was formerly with the Cornell Lab of Ornithology and is now director of the Centre for Research into Ecological & Environmental Modelling at Scotland’s University of St. Andrews, as the Cornell Chronicle reported. “Locations that once provided ideal habitat and climate for these species are no longer suitable. I think this is indicative of more major shifts happening for the nature that’s around us.”
Of the species the researchers examined, 83 percent were losing more of their populations in places they were most plentiful.
The team at the Lab of Ornithology analyzed birdwatchers’ observations of 36 million birds shared in the lab’s eBird program, as well as environmental variables derived from satellite images of 495 North American bird species from 2007 to 2021.
“We’ve known for several years that a lot of bird species in North America have been declining. With this study, we were aiming to understand in much finer spatial resolution where birds were declining and where they might be increasing. Rather than having a range-wide trend to see if a species is going up or down, we want to know where it is going up and down,” Johnston said, as reported by The Guardian.
The stark findings followed the recent United States’ State of the Birds 2025 report, which found declines in bird species across nearly every biome in the country, the Cornell Chronicle reported.
The research team said additional studies would be necessary to explain the causes of the declines, with populations falling by over 10 percent annually in some areas. Habitat changes and global heating were posited as the main theoretical causes, but the researchers ultimately didn’t know, Johnston said.
The research featured recent trends in bird populations at scales of 16.78 square miles — the smallest ever attempted for a study covering such a big geographic area.
“This is the first time we’ve had fine scale information on population changes across such broad spatial extents and across entire ranges of species. And that provides us a better lens to understand the changes that are happening with bird populations,” said Amanda Rodewald, a professor in the Department of Natural Resources at Cornell, as well as the faculty director of the Center for Avian Population Studies at the Cornell Lab of Ornithology, as reported by the Cornell Chronicle.
Earlier continental and national monitoring programs could only estimate population trends across entire regions, provinces, states or ranges. However, with the accumulation of large amounts of data and advances in machine learning, researchers are now able to examine how well species are faring in areas roughly the size of New York City.
“Results revealed high and previously undetected spatial heterogeneity in trends; although 75% of species were declining, 97% of species showed separate areas of significantly increasing and decreasing populations,” the authors wrote in the findings. “These high-resolution trends improve our ability to understand population dynamics, prioritize recovery efforts, and guide conservation at a time when action is urgently needed.”
Some bird species appeared to be doing well within a region or across their range, but were struggling in specific locations.
“The super interesting thing is, for almost all species, we found areas of population increases and decreases. This spatial variation in population trends has been previously invisible when looking at broader regional summaries,” Johnston said. “Areas where species are increasing where they’re at low abundance may be places where conservation has been successful and populations are recovering, or they may point to locations where there may be potential for recovery.”
The detailed mapping of population shifts will assist policymakers and conservation organizations in better targeting efforts to safeguard declining bird species, which the authors said is desperately needed to help reverse falling population trends.

“It’s this small-scale information across broad geographies that has been lacking, and it’s exactly what we need to make smart conservation decisions,” Rodewald said, as the Cornell Chronicle reported. “These data products give us a new lens to detect and diagnose population declines and to respond to them in a way that’s strategic, precise and flexible. That’s a game changer for conservation.”
The research also demonstrated the importance of citizen scientists.
“Because of the volunteers that engage in programs like eBird, because of their enthusiasm and engagement, and generosity of time, we now know more about bird populations and more about the environment than we ever have before,” Rodewald added.
The study, “North American bird declines are greatest where species are most abundant,” was published in the journal Science.
“Without the massive amount of data available from eBird, we would not have been able to complete this study,” said Daniel Fink, a statistician and senior research associate with the Cornell Lab of Ornithology.

Outdoor Projects You Can DIY for Almost Nothing
It always strikes us as amusing how many DIY projects you see online that seem to require more time and more money than it would take to simply buy the thing they’re trying to DIY in the first place. Are we missing the point?
We think that doing things ourselves and taking back the power to create instead of simply consuming is absolutely vital to the green movement. But if you don’t already have the materials and spend a lot of money purchasing craft supplies, does it really make sense to DIY?
These eight projects are true do-it-yourself masterpieces. One-of-a-kind outdoor projects you can make for almost nothing, with supplies you most likely already have or can easily pick up second hand for a song. Roll up your sleeves and let’s get started!
1. Teapot/Teacup Bird Feeder

Do you have one of Grandma’s old tea sets lying around that doesn’t quite fit into the sleek modern aesthetic you’ve been cultivating? Put it to great use by feeding the birds in your area — in style.
Thrift stores are always awash in old china, so if you don’t already have the old tea set, consider going wild and spending a few bucks for this DIY delight. You’ll find blogger Dinah Wulf’s instructions for the teacup bird feeder at DIY Inspired.
Safety note: Use sturdy twine or cord — not chain — to hang the feeder. Birds can catch their toes in chain links, which causes serious injury. The National Audubon Society also recommends cleaning seed feeders every two weeks (more often in hot, humid weather) by scrubbing with soap and water and soaking in a 50-50 vinegar-water solution to prevent the spread of avian disease.
2. Gardening Tool Storage

What on earth do you do with those rusty-as-heck, old-school garden rakes hanging around your garage? Well, if you’re any sort of DIY genius, you press them into service as a gardening tool holder.
The original inspiration for this project came from Beth Logan at Artstuff Ltd., whose blog has since gone offline. For a current walkthrough, see the Repurposed Rake Tool Rack tutorial at DIY n Crafts (project #14 in their roundup of 25 ways to reuse old garden tools). The concept is embarrassingly simple — remove the rake handle, mount the head tines-out on a fence or garage wall, and use the tines themselves as hooks for trowels, gloves, and pruners — but eye-catching enough to make you look like a DIY pro.
3. Bottle Tree

Do you like wine? No, I mean do you really like wine? Do you want a reason to drink more of it? And does your garden need a cute border? This sustainable, upcycled garden border may be just the project for you. You might have to expand your drinking list to include bottles of various shapes, sizes, and colors — but variety is the spice of life.
When friends ask how you managed to collect so many bottles, just laugh gaily and then distract them with your dainty teacup bird feeder. The bottle tree tradition itself runs deep — Mississippi garden writer Felder Rushing traces the practice back through African American Southern folk art and, by his own research, as far as ancient Egypt and Mesopotamia. See his bottle tree gallery and history for inspiration, or jump straight to his how-to guide for building one out of a cedar snag, rebar, or just about anything else.
4. Colorful Outdoor “Tiles”

If your backyard isn’t perfectly landscaped and manicured, with an impeccably tiled “outdoor living space,” don’t despair. You can use up all those half-empty paint cans and create a Pinterest-worthy colorful backdrop for evenings spent clustered around a fire or barbecue.
Pop a few coats of paint on cement tiles and you have a one-of-a-kind flooring solution. If you rent, the same effect could be achieved on a more temporary basis by letting the kids go wild with sidewalk chalk and create a mosaic masterpiece. Check out Elsie’s Painted Patio Tiles at A Beautiful Mess for the back story on this DIY idea. (Heads up: the original author noted she had to touch up the paint each spring in Missouri winters — a porch and patio floor enamel will hold up better than wall paint.)
5. Home Sweet Gnome

Okay, this one might be the least practical idea of the bunch, but that may be why I love it oh so much. If you have a stump in your backyard and you’re not willing or able to pay the truly insane amount it costs to have it ground down and removed, how about making it into a little gnome home? This is the perfect outdoor project if you have small children in your life.
Construct the trappings of a little house — door, windows, winding garden path — from found objects or natural materials, and affix them to the stump. Bonus points if you don’t tell the kids about this particular DIY project and allow them to simply stumble upon it one day in the garden. My mind would have been blown if I had come across one of these as a seven-year-old. For a step-by-step build, see this Gnome Tree Stump Home tutorial on Instructables.
Safety note: Don’t use an angle grinder to gouge windows or doors into a stump. Use a chisel and mallet for shallow detail work, or attach decorative pieces (driftwood, bark, polymer clay) to the outside instead.
6. Mosaic Stepping Stones from Broken China

Every household eventually accumulates a small graveyard of chipped mugs, a single survivor from a four-piece dinner set, or a beloved teapot with a hairline crack. Rather than tossing them — broken ceramics generally aren’t accepted in curbside recycling — embed them in concrete stepping stones for a garden path that’s genuinely one of a kind.
This pairs beautifully with the teacup project above: any teacups that don’t make it past Project #1 (you will break a few) can come back as paving. The DIY mosaic stepping stones tutorial at Gardening.org walks through the full process — breaking ceramics safely inside a drop cloth, sizing pieces to half-inch to one-inch fragments, pressing them into wet concrete, and sealing the surface so sharp edges don’t cause injury underfoot. Basic mold options include an old cake pan, a plastic plant saucer, or a purpose-built stepping stone form from a craft store.
Safety note: Wear safety glasses and heavy gloves when breaking ceramics. Once cured, run a finger over the surface to check for protruding edges and file or sand any down before placing the stone where bare feet might land.
7. Vertical Pallet Herb Garden
Shipping pallets are one of the world’s most abundant near-free materials. Small businesses, garden centers, and feed stores often have stacks of them out back, and asking politely beats the alternative of seeing them landfilled. Mounted vertically against a sunny wall or fence, a pallet becomes a stacked planter that holds enough herbs to keep a kitchen in basil, thyme, parsley, and chives all season.
Grit Magazine published a clear how-to for a vertical pallet planter — line the back and sides with landscape fabric or heavy plastic to hold soil, fill through the slats, and plant each gap as its own row. The gaps act as natural divisions, so different herbs don’t fight for the same root space.
Safety note: Use only heat-treated pallets for anything edible. Look for the IPPC stamp with the letters HT (heat treated) and avoid any stamped MB (methyl bromide — a fumigant restricted under the Montreal Protocol). Unstamped pallets are unknowns; skip them for food crops. The same heat-treated pallets are fine for ornamental flowers either way.
8. Punched Tin Can Lanterns
Steel food cans — soup, tomato, coffee — are one of the most recyclable materials on Earth, but the recycling-then-buying-something-decorative loop has plenty of slack in it. With nothing more than a hammer, a few nails of varying sizes, and the freezer, an empty can becomes an outdoor lantern that throws constellation patterns across a patio at dusk.
HGTV’s tin can lantern tutorial covers the trick that makes this project work: fill the can with water and freeze it solid before punching, so the ice supports the can wall and prevents denting. Sketch your pattern on paper, tape it to the frozen can, punch through with a nail at each marked dot, and let the ice thaw. Drop in a battery tealight (much safer outdoors than a real flame) and group them along a walkway or down the center of an outdoor table.
The Point of All This
None of these projects requires you to buy more than a tube of waterproof adhesive, a bag of concrete, or maybe a stepping stone mold. The materials — chipped china, leftover wine bottles, empty cans, a forgotten pallet, an old rake — are already in your house or someone else’s. That’s the point. The greenest project is the one that uses what already exists, and the best part is that yours will look like nobody else’s.

Best of Sustainability In Your Ear: Author Nadina Galle on The Nature of Our Cities
More than half the world’s population—4.4 billion people—live in cities today. That number is expected to rise to 80% by 2050. Our guest, Nadina Galle, is a trailblazing ecological engineer and author of The Nature of Our Cities. She is an ecological engineer who studies the intersection of nature and technology in urban environments. Nadina developed the concept of an Internet of Nature (IoN) that uses tools like artificial intelligence, automation, and sensors to support and enhance ecosystems within cities. Nadina’s book offers a transformative perspective on how urban spaces can be reimagined in the face of climate change and sprawling development. She shares the inspiring story of the Groene Loper project in Maastricht, Netherlands, where soil sensors were deployed to monitor tree health. The results were remarkable, with trees supported by this technology growing up to three times larger than those without it. This is a powerful example of how technology can not only protect trees but also transform urban spaces into healthier, greener environments.

From fire and the wheel to the reinforced concrete frames that define modern buildings, we are surrounded by technology. We tend to forget that technology emerged in response to nature — too often, we treated nature as the enemy, the chaos to be contained instead of recognizing that nature’s cycles and changes are the harmony we need to join to sustain society. The loss of any semblance of natural patterns, which ultimately leads to the depletion of the resources necessary for life, has inevitably led to the collapse of previous major civilizations. Modern society has more runway than previous societies because we have created a global economy, but that risks an even greater fall for our species when the ecological underpinnings of our prosperity collapse. The Nature of Our Cities, is a powerful, straightforward, and emotionally resonant book to help you think through your role and choices in the restoration of nature. You can find it on Amazon or Powell’s Books.
