The report first complete examine of the nation’s birds since 2019, when it was discovered that just about 3 billion birds had been misplaced within the U.S. and Canada within the previous 50 years.

  • Throughout the identical interval, waterbirds and geese elevated by 18% and 34%, respectively.
  • 70 Tipping Level species have been recognized, with every having misplaced 50% or extra of their populations within the final 50 years. If nothing adjustments, they’re predicted to lose one other half within the subsequent 50 years. These species embrace the rufous hummingbird, golden-winged warbler, and black-footed albatross, none of that are presently listed beneath the Federal Endangered Species Act.
  • Hawaii’s ten most endangered species are collectively represented by fewer than 5,500 particular person birds.


The report particulars two important developments, one hopeful and one dire.

The excellent news is that long-term monitoring of waterfowl has proven inhabitants will increase in areas the place investments in wetland conservation have improved circumstances for each birds and folks.

Nonetheless, information has proven that birds are declining in each different habitat, together with grasslands, deserts, forests, and oceans.

The U.S. Fish and Wildlife Service recognized 269 migratory and nongame chicken species which might be more likely to change into candidates for itemizing on the Birds of Conservation Concern (BCC) record except extra conservation measures are taken.

Though the State of the Birds report reveals a really dismal view of the state of U.S. birds, it highlights how funding in conservation efforts can efficiently get well species.

Tipping Level Birds

70 tipping level species have been recognized within the State of the Birds 2022 report. Beneath are footage and attention-grabbing data on 10 notable tipping level species.

The Migratory Chicken Treaty Act has protected over a thousand chicken species, with 89 having acquired extra protections to forestall their extinction, as they’re listed as both threatened or endangered.

The tipping level species are extra birds which have been recognized as people who might be listed subsequent, and which have cumulatively misplaced greater than two-thirds of their populations within the final 50 years.

These species are actually both on a trajectory to lose an additional 50% of their populations within the subsequent 50 years, or have already got critically low populations and face vital threats however lack enough information.

American Golden Plover

American Golden Plover

Discovered breeding throughout the tundra of North America, the American Golden Plover is a particular shorebird with very putting markings. People return to the identical breeding areas 12 months after 12 months, and territories are defended by each men and women. The species’ nest consists of a shallow scrape lined with lichen.

Local weather change poses the best risk to the golden plover, as rising temperatures are inflicting southern parts of their vary to change into uninhabitable.

Black-Footed Albatross

Black Footed Albatross

The Black-footed albatross is a big seabird discovered across the North Pacific Ocean, with many of the inhabitants breeding on the Northwestern Hawaiian Islands. It’s the solely dark-plumaged albatross discovered within the North Pacific, and when not breeding will wander throughout the Pacific so far as Alaska, California, Taiwan, and the Bering Sea.

This albatross primarily feeds on squid and the eggs of flying fish, nonetheless, it’s also recognized to comply with ships and trawlers, benefiting from any offal left behind.

Threats to the species’ survival embrace bycatch from fisheries and rising sea ranges which flood their nests and cut back out there nesting websites.



The Bobolink is a rare migrant, making a round-trip of round 20,000km from North America to areas south of the Equator. It was one of many first polygynous species to be documented, the place females lay a clutch of eggs sired by a couple of male.

The Bobolink is also referred to as the “Rice chicken” as it’s recognized to feed on cultivated grains, and it has usually been persecuted as an agricultural pest.

The principle reason for this species’ decline is the change in agricultural practices leading to fewer meadows and hay fields for it to forage in (supply).

Chimney Swift

Chimney swifts spend the winter within the higher Amazon basin earlier than migrating to North America in massive numbers. They’re most noticeable throughout migration, when flocks of hundreds of birds circle above chimneys in tornado-like formations, earlier than descending to roost at nightfall.

The species nests in chimneys and previous buildings, establishing nests from woven twigs, held collectively by their glue-like saliva, on vertical surfaces.
