Deer Flat National Wildlife Refuge: The Deer Flat National Wildlife Refuge is an important breeding area for mammals, birds, and other animals.  The National Wildlife Refuge is located on land surrounding Lake Lowell, just outside Nampa, Idaho.  It serves as a resting and wintering area for birds, including mallards and Canada geese, along the Pacific Flyway and was named a "Globally Important Bird Area" by the American Bird Conservancy.

North American Bird Phenology Program: The North American Bird Phenology Program houses a unique and largely forgotten collection of six million Migration Observer Cards that illuminate migration patterns and population status of the birds of North America.  These handwritten cards contain almost all of what was known of bird distribution and natural history from the latter part of the 19th century through World War II.  The bulk of the records are the result of the work of a network of observers who recorded migration arrival dates in the spring and fall in a program that, in its heyday, involved 3000 participants.  Today, those records are being processed and placed into a modern database for analysis.  This information will be used, along with recently collected arrival times of migrant birds, and in conjunction with historical weather data, to examine how bird migration is being affected by climate change.  The information from this analysis will provide critical information on bird distribution, migration timing and migration pathways and how they are changing.  There is no other program that has this depth of information that can help us understand the effect that global climate change has on bird populations across the continent.

Clay-colored thrush: The clay-colored thrush ("Turdus grayi") is a common Middle American bird of the thrush family (Turdidae).  It is the national bird of Costa Rica, where it is well known as the yigüirro.  Other common names include clay-colored robin.

Tawny-throated leaftosser: The tawny-throated leaftosser ("Sclerurus mexicanus") is a tropical American bird species in the ovenbird family Furnariidae.  It is also known as the tawny-throated leafscraper, Mexican leaftosser or Mexican leafscraper.  This bird might be a cryptic species complex.

Cinereous harrier: The cinereous harrier ("Circus cinereus") is a South American bird of prey of the harrier family.  Its breeding range extends from the Tierra del Fuego through Argentina and Chile to Bolivia, Paraguay, Peru and southern Brasil; and across the Andes north to Colombia.  The bird's population is declining but due to its large range is not considered vulnerable.  The term "cinereous", deriving from the Latin word for ashy, describes its colouration.

Hayabusa (train): The Hayabusa (はやぶさ , literally Peregrine Falcon) is a high-speed Shinkansen service operated by East Japan Railway Company (JR East) and Hokkaido Railway Company (JR Hokkaido) between Tokyo and Shin-Hakodate-Hokuto in Japan since 26 March 2016.  The name was formerly used for a limited express sleeping car service operated by JR Kyushu, which ran from Tokyo to Kumamoto , and was discontinued in March 2009.

Labrador duck: The Labrador duck ("Camptorhynchus labradorius") was a North American bird; it has the distinction of being the first endemic North American bird species to become extinct after the Columbian Exchange, with the last known sighting occurring in 1878 in Elmira, New York.  It was already a rare duck before European settlers arrived, and as a result of its rarity information on the Labrador duck is not abundant, although some, such as its habitat, characteristics, dietary habits and reasons behind its extinction, are known.  There are 55 specimens of the Labrador duck preserved in museum collections worldwide.

Short-tailed hawk: The short-tailed hawk ("Buteo brachyurus") is an American bird of prey in the family Accipitridae, which also includes the eagles and Old World vultures.  As a member of the genus "Buteo", it is not a true hawk and thus also referred to as a "buteo" or (outside North America) "buzzard".  The white-throated hawk ("B. albigula") is a close relative and was formerly included in the species "B. brachyurus".

Peregrine falcon: The peregrine falcon ("Falco peregrinus"), also known as the peregrine, and historically as the duck hawk in North America, is a widespread bird of prey in the family Falconidae.  A large, crow-sized falcon, it has a blue-grey back, barred white underparts, and a black head.  As is typical of bird-eating raptors, peregrine falcons are sexually dimorphic, with females being considerably larger than males.  The peregrine is renowned for its speed, reaching over 200 mph during its characteristic hunting stoop (high speed dive), making it the fastest member of the animal kingdom.  According to a National Geographic TV programme, the highest measured speed of a peregrine falcon is 389 km/h .

North American Bird Banding Program: The North American Bird Banding Program (NABBP), along with its Bird Banding Laboratory (BBL), has its home at the Patuxent Wildlife Research Center.  The program is jointly administered by the Canadian Wildlife Service (and its Bird Banding Office) and the United States Geological Survey.  The program is responsible for many aspects of bird banding in the United States and Canada: it grants permits to bird banders, fills orders for bands of various sizes, collects data from banding stations, receives reports from people who have found birds carrying bands, and makes its database available to appropriate parties.
