Terrestrial Birds

Terrestrial birds, also called ground/land birds, are birds that usually spend most of their life on the ground, in bushes, or low in the shrubbery. Most of these birds are flightless and if they can fly would remain close to the ground. They are identified by small, often round heads, blunt, round wings, heavily camouflaged plumage, strong, powerful long legs, and preference for dust baths or sunbathing. Most are herbivorous and stay in a large family or groups besides being non-migratory. They may include game birds and chicken breeds. Many are a good source of food for carnivores and omnivores. However, they are defenseless to habitat loss.

How are terrestrial and marine birds different?

Terrestrial and marine birds are different as marine birds can make a home anywhere and live in the open ocean as they have no attachment to the land. Terrestrial birds in contrast are attached to the land they live on. Terrestrial birds also forage the ground for food while marine birds look for food during their flights.

Can terrestrial birds fly?

Horned Guan (Oreophasis derbianus)
Scale illustration of an average Horned Guan compared to other gamefowl species

The Horned Guan (Oreophasis deerbianus) is a turkey-like gamefowl that is a poor flyer and spends most of its time sleeping and eating. It has a glossy black plumage, red legs, and a red horn on top of its head. The Horned Guan also has a white belly and breast. It is native to the mountain forests of the south of Mexico and Guatemala in South America. The Horned Guan is often found at altitudes of up to 10,990 ft (3,350 m). It generally eats fruits, flowers, leaves, and some invertebrates or small vertebrates. The Horned Guan is considered endangered to extinction.

The Horned Guan has a wingspan in the range of 35.4”-51.2” (90-130 cm) and total weight of 4.4-5.5 lb (2-2.5 kg). The body of the Horned Guan has an overall length between 33.5”-46” (85-117 cm), body width of 7.5”-10.2” (19-26 cm), and standing height of roughly 17.3”-23.6” (44-60 cm). The typical lifespan of the Horned Guan is between 10-20 years.

Mountain Quail (Oreortyx pictus)
Comparison drawing of the Mountain Quail compared to other gamefowl

The Mountain Quail (Oreortyx pictus) is a small ground-dwelling gamebird with short wings and long featherless legs. It is characterized by its top knots that are shorter in the female Mountain Quail. The Mountain Quail has a brown face, gray breast, brown back, and white underside. Its habitat ranges from the Rocky Mountains in the United States to Baja Peninsula in Mexico. A Mountain Quail is typically found in altitudes of up to 9,800 ft (3,000 m). The diet of the Mountain Quail is mostly made up of plant matter and seeds. A chick may eat insects and more plant matter as it matures.

The Mountain Quail has a wingspan in the range of 13.8”-15.75” (35-40 cm) and total weight of .42-.64 lb (.19-.29 kg). The body of the Mountain Quail has an overall length between 10.2”-11” (26-28 cm), body width of 2.75”-3.15” (7-8 cm), and standing height of roughly 7.9”-8.9” (20-22.5 cm). The typical lifespan of the Mountain Quail is between 2-4 years.

Spruce Grouse (Canachites canadensis)
Comparison drawing of the Spruce Grouse compared to other gamefowl

The Spruce Grouse (Falcipennis canadensis) also known as the Canada Grouse, is medium-sized and differs from one another in plumage and tail patterns. The male Spruce Grouse has gray back with black underside with a red patch of bare skin called the ‘eyebrow comb’. The female is either brown or marbled gray. The Spruce Grouse is native to the mountains and forests of North America. A Spruce Grouse forages the ground for food like small plants, fungi, and insects. It can store up to 10% of its body weight in food, digesting it when it is at safety or during the night.

The Spruce Grouse has a wingspan in the range of 21.25”-22.8” (54-58 cm) and total weight of 1-1.72 lb (.45-.78 kg). The body of the Spruce Grouse has an overall length between 15”-16.9” (38-43 cm), body width of 4.5”-5.3” (11.5-13.5 cm), and standing height of roughly 10”-11.6” (25.5-29.5 cm). The typical lifespan of the Spruce Grouse is between 5-6 years.

Osprey (Pandion haliaetus)
Comparison drawing of the Osprey compared to other birds of prey

The Osprey (Pandion haliaetus) is a large long-winged hawk that lives along seacoasts to catch fish, nesting in nearly every continent except for Australia and Antarctica. Also known as the fish hawk, sea hawk, or river hawk, the osprey hovers above the water in search of fish and captures its prey with its large, sharp talons. The osprey has brown upperparts, white undersides, a black bill, and white feet with black talons.

The Osprey has a wingspan in the range of 50”-70.9” (127-180 cm) and total weight of 2.4-4.4 lb (1.1-2 kg). The body of the Osprey has an overall length between 16.9”-24” (43-61 cm), body width of 4.5”-6.7” (11.5-17 cm), and standing height of roughly 11.4”-16.3” (29-41.5 cm). The typical lifespan of the Osprey is between 25-32 years.

Prairie Falcon (Falco mexicanus)
Scale illustration of an average Prairie Falcon compared to other bird of prey species

The Prairie Falcon (Falco mexicanus) is a falcon that lives in the arid open countries, alpine tundras, shortgrass prairies, and high deserts of North America. They can be found in southern Canada through the western United States, and into northern Mexico. The plumage is a warm gray-brown above with a pale mottling below. The primary wing feathers are the darkest, and the rump and tail are the lightest. The Prairie Falcon mostly eats small mammals and small to medium-sized birds that are caught in flight, and as opportunistic predators, they will sometimes take larger birds.

The Prairie Falcon has a wingspan in the range of 35.4”-44.5” (90-113 cm) and total weight of 1.1-2.1 lb (.5-.95 kg). The body of the Prairie Falcon has an overall length between 15”-19.7” (38-50 cm), body width of 3.5”-4.7” (9-12 cm), and standing height of roughly 8.3”-10.6” (21-27 cm). The typical lifespan of the Prairie Falcon is between 15-20 years.
