Lit:

There are several varieties of this bird including the common lit, crested lit, and the needle-tailed lit. They are all found in the rainforests. The crested lit is brightly plumaged with red and yellow feathers.

Mindar:

This bird is similar to a hummingbird. It is a short winged, yellow and red bird of the rainforests. It uses its sharp bill to dig at the bark of flower trees for larvae and insects. Its wings have adapted for short, rapid flights.

Tanager:

This is a brightly plumaged bird in the rainforests near Schendi.

Tarns:

These are the giant riding birds of Gor, also called the Brothers of the Wind. They resemble a hawk but with a crest like a jay. They are surprisingly light for their size due to the hollowness of their bones. A tarn is an extremely powerful bird. It can fly from the ground with a spring and sudden wing flurry. Its tongue is thin, sharp and as long as a man's arm. It has a curved beak, slit with narrow nostrils. They are not migratory birds and cannot live in the cold northern regions. Tarns are diurnal and carnivorous. They eat only what they catch themselves, usually antelopes and wild bull. If enough food is available, they will eat half their weight. But by Renegades of Gor, tarns are being trained to eat prepared meat. They are seldom more than half-tamed and it is not unknown for a tarn to attack its own rider. Their plumage varies and they are bred for color. The most common color is greenish-brown. Black tarns used for night raids, white for winter raids, and multi-colored for proud warriors who care not for camouflage. It is extremely difficult to fly a tarn from the sight of land. The jungle tarn is a rare bird, gloriously plumaged, from the tropical reaches of the Cartius. Tarns often are trained for specific functions. Draft tarn are used for transporting cargo while Saddle tarns are used for transport of people. War tarns are used by Tarnsmen in battle. Racing Tarns are made for entertainment like Earth horse racing. Racing tarns are different in size, strength, build, and tendencies from most other tarns. They are extremely light so that two men could lift one. Its wings are broader and shorter permitting a swifter take off and a capacity for extremely abrupt turns and shifts in flight. They lack the stamina of most other tarns and cannot carry heavy weight.

" Though the tarn, like most birds, is surprisingly light for its size, this primarily having to do with the comparative hollowness of the bones, it is an extremely powerful bird, powerful even beyond what one would expect from such a monster. Whereas large Earth birds, such as the eagle, must, when taking flight from the ground, begin with a running start, the tarn with its incredible musculature, aided undoubtedly by the somewhat lighter gravity of Gor, can with a spring and a sudden flurry of its giant wings lift both himself and hi rider into the air. In Gorean, these birds are sometimes spoken of as Brothers of the Wind.

The plumage of tarns is various, and they are bred for their colors as well as their strength and intelligence. Black tarns are used for night raids, white tarns in winter campaigns, and multicolored, resplendent tarns are bred for warriors who wish to ride proudly, regardless of the lack of camouflage. The most common tarn, however is greenish brown. Disregarding the disproportion in size, the Earth bird which the tarn most closely resembles is the hawk, with the exception that it has a crest somewhat of the nature of a jay's. 

Tarns, who are vicious things are seldom more than half tamed and, like their diminutive earthly counterparts, the hawks, are carnivorous. It is not unknown for a tarn to attack and devour his own rider. They fear nothing but the tarn-goad.."

~Tarnsman of Gor, pages 51-52~

"The tarn is guided by virtue of a throat strap, to which are attached, normally, six leather
streamers, or reins, which are fixed in a metal ring on the forward portion of the saddle. The reins are of different colors, but one learns them by ring position and not color. Each of the reins attaches to a small ring on the throat strap, and the rings are spaced evenly. Accordingly, the mechanics are simple. One draws on the streamer, or rein, which is attached to the ring most nearly approximating the direction in which one wishes to go. For example, to land or lose altitude, one uses the four-strap which exerts pressure on the four-ring, which is located beneath the throat of the tarn. To rise into flight, or gain altitude, one draws on the one-strap, which exerts pressure on the one-ring, which is located on the back of the tarn's
neck. The throat-strap rings, corresponding to the position of the reins on the main saddle ring, are numbered in a clockwise fashion."

~Tarnsman of Gor, page 55~

Tibit:

This is a small, thin-legged bird that lives on tiny mollusks on the shores of Thassa.

Tumit:

This is a large flightless bird of the prairies with a hooked beak as long as a forearm. Wagon Peoples hunt these with bolas.

"...beyond them I saw one of the tumits, a large, flightless bird whose hooked beak, as long as my forearm, attested only too clearly to its gustatory habits; I lifted my shield and grasped the long spear,  but it did not turn in my direction; it passed, unaware;..."

~Nomads of Gor, page 2~

"I gathered that the best season for hunting tumits, the large, flightless carnivorous birds of the southern plains was at hand..."

~Nomads of Gor, page 331~

Ul:

This is a silent, giant pterodactyl-like creature that is native to the swamps of the Vosk delta. It is a predatory winged tharlarion. It has a wing span of twenty-five to thirty Gorean feet. It has a small head with long, narrow toothed jaws with a narrow extension of bone and skin in the back. Its long snake-like tail ends in a spadelike structure. It has a clawed hand with a very long fourth digit. There are several smaller varieties, some as small as a jard. The larger ones are isolated and territorial. They will not attack a tarn as a tarn could easily tear them to pieces.

"Only one creature in the marshes dares to outline itself against the sky, the predatory Ul, the winged thalarion."

~Raiders of Gor, page 1~

"Also, at night, crossing the bright disks of Gor's three moon,  might ocassionally be seen the silent, predatory shadow of the ul, a giant pterodactyl ranging far from its native swamps in the delta of the Vosk."

~Outlaw of Gor, page 26~

Umbrella bird:

This bird lives in the rainforest.

Vart:

These are blind, batlike flying rodents. They can grow to the size of a small dog. They can strip a carcass in minutes. Some are rabid and they hang upside down like bats. There are jungle varts in the rainforests. Varts on Tyros are trained as weapons.

"Perhaps most I dreaded those nights filled with the shrieks of the vart pack, a blind, batlike swarm of flying rodents, each the size of a small dog. They could strip a carcass in a matter of minutes...Moreover, some vart packs were rabid."

~Outlaw of Gor, page 26~

"I could, however, recognize a row of brown varts, clinging upside down like large matted fists of teeth and fur and leather on the heavy, bare, scarred branch in their case."

~Priest-Kings of Gor, page 191~

"Tyros is a rugged island, with mountains. She is famed for her vart caves, and indeed, on that island, trained varts, batlike creatures, some the size of small dogs, are used as weapons."

~Raiders of Gor, page 139~

Veminium bird:

This is a songbird that may live among veminium flowers.

Vulos:

These are domesticated, tawny-colored pigeons raised for eggs and meat. At least some of their meat is white.

"She was a peasant, barefoot, her garment little more than coarse sacking.  She had been carrying a wicker basket containing vulos, domesticated pigeons raised for eggs and meat."

~Nomads of Gor, page 1~

"Soon, I smelled the frying of vulo eggs in a large, flat pan…"

~  Slave Girl of Gor, page 73~

"I smelled roast bosk cooking, and fried vulo...I held the leg of the fried vulo toward one of the girls..."

~Hunters of Gor, page 34~

"...the shattered, slatted coops for vulos, the broken walls of keeps for the small, long-haired domestic verr, less belligerent and sizable than the wild verr of the Voltai ranges."

~Nomads of Gor, page 10~

Wader:

There are at least two varieties of this waterbird in the rainforests. This includes the ring-necked wader and the yellow-legged wader.

Zadit:

This is a small, tawny-feathered, sharp billed bird of the Tahari. It is insectivorous, feeding on sand flies and other insects. It often lands on kaiila and eats the insects on this animal. They leave small wounds on the kaiila which the drovers treat with poultices of kaiila dung.

"The zadit is a small, tawny-feathered, sharp-billed bird. It feeds on insects. When sand flies and other insects, emergent after rains, infest kaiila, they frequently light on the animals, and remain for some hours, hunting insects. This relieves the kaiila of the insects but leaves it with numerous small wounds, which are unpleasant and irritating, where the bird had dug insects out of its hide."
