As of my last update in September 2021, the United States is home to a diverse range of bird species. Some of these birds have limited ranges within the country, making them relatively rare and sought after by birdwatchers. Here are eight such rare birds:

California Condor (Gymnogyps californianus): The California Condor is one of the largest flying birds in North America. It was once on the brink of extinction but has seen efforts for reintroduction and recovery in specific areas of California, Arizona, and Utah.

Kirtland’s Warbler (Setophaga kirtlandii): The Kirtland’s Warbler is a small, endangered songbird with a very limited breeding range in young jack pine forests of northern Michigan.

Gunnison Sage-Grouse (Centrocercus minimus): The Gunnison Sage-Grouse is a rare and threatened species found in isolated pockets of sagebrush habitat in Colorado and a small part of Utah.

Florida Scrub-Jay (Aphelocoma coerulescens): The Florida Scrub-Jay is the only species of jay native to Florida and is found in specific scrub habitats in the state.

Island Scrub-Jay (Aphelocoma insularis): The Island Scrub-Jay is limited to Santa Cruz Island off the coast of California and is known for its striking blue plumage.

Whooping Crane (Grus americana): The Whooping Crane is one of the rarest cranes in the world, with a small population migrating between Texas and Wood Buffalo National Park in Canada.

Ivory-billed Woodpecker (Campephilus principalis): While its existence is highly debated, the Ivory-billed Woodpecker, if still extant, would have a limited range in the southeastern United States.

Hawaiian Honeycreepers (Family: Drepanididae): These colorful and diverse birds are native to Hawaii and have evolved into various species, ɱaпy of which are highly endangered due to habitat loss and introduced diseases.

Please note that the status and distribution of bird species can change over ᴛι̇ɱe due to conservation efforts, habitat changes, and other factors. For the most current and accurate information, I recommend checking with ornithological organizations or birdwatching groups that regularly update their databases on bird sightings and distributions.
