Finches
A bird found in the level of the canopies of the rain forest In the second level, that of the canopies, is found an incredible variety of birds, warblers, finches, mindars, the crested lit and the common lit, the fruit tindel, the yellow gim, tanagers, some varieties of parrot, and many more. Here, too, may be found snakes and monkeys, gliding urts, leaf urts, squirrels, climbing, long tailed porcupines, lizards, sloths, and the usual varieties of insects, ants, centipedes, scorpions, beetles and flies, and so on.

fishers, tufted Along  the river, of course, many other species of birds may be found, such as  jungle gants, tufted fishers and ring-necked and yellow-legged waders. Also  in the ground zone are varieties of snake, such as the ost and hith, and numerous species of insects. The rock spider has been mentioned, and termites also. Termites, incidentally, are extremely important to the ecology of the forest. In their feeding they break down and destroy the branches and trunks of fallen trees. The termite dust,  thereafter, by the action of bacteria, is reduced to humus, and the humus to nitrogen and mineral materials.
Explorers of Gor  page 311-312 fisher, ushindi
long-legged, wading bird near the Schendi, long, white, curling feathers  are sometimes used for headdresses. Behind and about him had swirled a gigantic cloak of yellow and red feathers, from the crested lit and the fruit tindle, brightly plumaged birds of the rain forest. In making such a cloak only two feathers are taken from the breast of each bird. It takes sometimes a hundred years to fashion such a cloak. Naturally it is to be worn only by a Ubar. His head was surmounted by an elaborate headdress, formed largely from the long, white, curling feathers of the Ushindi fisher, a long-legged, wading bird. It was not unlike the common headdress of the askari. Indeed save for the length of the feathers and the intricate leather and beading, in which the feathers were mounted, it might have been such a headdress.

Gant

gant, arctic
migratory bird that nests on cliffs in the Hrimgar Mountains, the southern border of the polar north.   When frozen, their eggs are eaten like apples. I stepped aside to let a young girl pass, who carried two baskets of eggs, those of the migratory arctic gant.  They nest in the mountains of the Hrimgar and in steep, rocky outcroppings, called bird cliffs, found here and there jutting out of the tundra.  The bird cliffs doubtless bear some geological relation to the Hrimgar chains.  When such eggs are frozen they are eaten like apples.

a long legged marsh bird with a piping cry, Broad billed,  web footed, winged, found in the Vosk Delta, small horned aquatic fowl. Hunted by Marsh girls and/or Rencers for food "I heard a bird some forty or fifty yards to my right; it sounded like a marsh gant, a small, horned, web-footed aquatic fowl, broad-billed and broad-winged. Marsh girls, the daughters of Rence growers, sometimes hunt them with throwing sticks."

Gim

gim, horned
a small purplish owl like bird, about 4 ozs. in weight, which inhabits the forests of northern Gor It was a small bird, about the size of a sparrow, but it looked a bit like a tiny owl, with tufts over it's eyes.  It was purplish.  It looked at me quizzically.  It was perched on some split piping.
Captive of Gor Pages 39

There was only the laughter of the girl's, the bubbling of the stream, the work, the blue sky and white clouds, the wind and the bending grass, clean air and, somewhere, the call of a tiny horned gim, the tiny purplish owllike bird.

Mindar
a short winged, yellow & red bird of the rain forests inland of Schendi; with its sharp bill, it digs in the bark of flower trees for larvae & bugs

Observe the water," said Kisu. "Smell the flowers and the  forest. I think that already we may be within its mouth."
I was startled. Could its mouth be so wide? Already we  were perhaps within the Ua.
 Kisu pointed overhead. "See the mindar," he said.
We looked up and saw a brightly plumaged, short winged,  sharp-billed bird. It was yellow and red.
"That is a forest bird," said Kisu.
The mindar is adapted for short, rapid flights, almost  spurts, its wings beating in sudden flurries, hurrying it from branch to branch, for camouflage in flower trees, and for drilling the bark of such trees for larvae and grubs.
 "Look!" said Ayari, pointing off to the left. There we saw a tharlarion, sunning itself on a bar. As we neared it, it slipped into the water and swam away.

Tarns
Enormous relatives of the earth Golden eagle, some with a 50' wing span, they are bred in 3 types

My first impression was that of a rush of wind and great snapping sound, as if a giant might be snapping an enormous towel or scarf; then I was cowering, awestricken, in a great winged shadow, and an immense tarn, his talons extended like gigantic steel hooks, his wings sputtering fiercely in the air, hung above me, motionless, except for the beating of his wings.
‘Stand clear of the wings,’ shouted the Older Tarl.
I needed no urging. I darted from under the bird. One of those wings would hurl me yards from the top of the cylinder.
The tarn dropped to the roof of the cylinder and regarding us with his bright black eyes.
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.  The tarn, with its incredible musculature, aided undoubtedly by the some what lighter gravity of Gor, can with a spring and a sudden flurry of its giant wings lift both himself and his rider into the air.
The plumage of tarns is various, and they are bred for their colours as well as their strength and intelligence. Black tarns are used for night raids, white tarns in winter campaigns, and multi-coloured, resplendent tarns are bred for warriors who wish to ride proudly, regardless of the lack of camouflage. The most common tarn, however, is the 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 counter parts, the hawks are carnivorous. It is not unknown for a tarn to attack and devour his own rider. They fear nothing but a tarn goad. They are trained by men of the Caste of Tarn Keepers to respond to it while still young, when they can be fastened by wires to the training perches. Whenever a young bird soars away or refuses obedience in some fashion, he is dragged back to the perch and beaten with the tarn-goad. Rings, comparable to those which are fastened on the legs of the young birds, are worn by the adult birds to reinforce the memory of the hobbling wire and the tarn goad. Later, of course, the adult birds are not fastened, but the conditioning given them in their youth usually holds, except when they become abnormally disturbed or have not been able to obtain food. The tarn is one of the two most common mounts of a Gorean warrior.
Tarnsman of Gor Pages 48 - 51

" 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 his 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.."

tarn, draft
huge, heavy, slower birds bred to carry large loads in hanging baskets or pallets over great distances I would later learn, it was not even a warrior's mount, bred for swiftness and aggressiveness, a war tarn, but a mere draft tarn.
Dancer of Gor Page 148 tarn, racing - slender, lighter birds bred for speed and endurance. Racing Tarns are also used by messengers to go from one city-state to another. "The tarns were, of course, racing tarns, a bird in many ways quite different from the common tarns of Gor, or the war tarns. The differences among these tarns are not simply in the training, which does differ, but in size, strength, build and tendencies of the bird. Some tarns are bred primarily for strength and are used in transporting wares by carrying basket. Usually these birds fly more slowly and are less vicious than the war tarns or racing tarns. The war tarns, of course, are bred for both strength and speed, but also for agility, swiftness of reflex, and combative instincts. War tarns, whose talons are shod with steel, tend to be extremely dangerous birds, even more so than other tarns, none of whom could be regarded as fully domesticated. The racing tarn, interestingly, is and extremely light bird; two men can lift one; even its beak is narrower and lighter than the common tarn or war tarn; its wings are commonly broader and shorter than those of other tarns, permitting a swifter take off..."
Assassin of Gor, pages 143-144 tarn, war- heavier but agile, trained to aid in battle, very ferocious. I would later learn, it was not even a warrior's mount, bred for swiftness and aggressiveness, a war tarn, but a mere draft tarn.
Dancer of Gor Page 148

Almost immediately from somewhere, perhaps from a ledge out of sight, rose a fantastic object, another giant tarn, even larger than the first, a glossy sable tarn which circled the cylinder once and then wheeled towards me, landing a few feet away, his talons striking on the roof with a sound like hurled gauntlets. His talons were shod with steel - - a war tarn. He raised his curved beak to the sky and screamed, lifting and shaking his wings. His enormous head turned towards me, and his round, wicked eyes blazed in my direction. The next thing I knew his beak was open, I caught a brief sight of his thin, sharp tongue, as long as a man’s arm, darting out and back, and then, snapping at me, he lunged forward, striking at me with that monstrous beak, and I heard the Older Tarl cry out in horror, ‘The goad! The goad!’
Tarnsman of Gor Page 51

Tibit
A small, thin legged bird which lives on tiny mollusks found on the shores of Thassa I heard the cry of sea birds, broad-wingered gulls and the small, stick-legged tibits, pecking in the sand for mollusks.
Hunters of Gor Page 247

Tumit
large flightless bird, about the size of an ostrich, having an 18' long hooked beak, carnivorous

"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..."

Ul
Giant Pterodactyl or Pteranodon, Native to the Vosk delta which has a wingspan of several feet

The delta of the Vosk, for most practical purposes, a vast marsh, an area of thousands of square pasangs, where the Vosk washes down to the sea, is closed to shipping. It is trackless and treacherous, and the habitat of marsh tharlarion and the predatory Ul, a winged lizard with wing-spans of several feet.

Umbrella Bird

In the lower portion of the canopies, too can be found heavier birds, such as the ivory billed woodpecker and the umbrella bird. Guernon monkeys, too, usually inhabit this level. In the ground zone, and on the ground itself, are certain birds, some flighted, like the hook-billed gort, which preys largely on rodents, such as ground urts, and insectivorous whistling finch, and some unflighted, like the grub borer and lang gim.

Vart
similar to a bat, it's a flying rodent, blind and carnivorous

"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

vart, brown "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 vart, jungle
a relative of the northern vart, it inhabits the rain forests inland of Schendi. In the lower branches of the ground zone may be found, also, small animals, such as tarsiers, nocturnal jit monkeys, black squirrels, four-toed leaf urts, jungle varts and the prowling solitary giani, tiny, cat-sized panthers, not dangerous to man. On the floor itself are also found several varieties of animal life, in particular marsupials, such as the armored gatch, and rodents, such as sleens and ground urts. Several varieties of tarsk, large and small, also inhabit this zone. More than six varieties of anteater are also found here, and more than twenty kinds of small, fleet, single-horned tabuk.
Explorers of Gor page 311-312

Vulo
a tawny colored poultry bird, similar to a pigeon, which also exists in the wild. The bird is used for meat and eggs. "I smelled roast bosk cooking, and fried vulo.   I held the leg of the fried vulo toward one of the
girls..."

Also  in the ground zone are varieties of snake, such as the ost and hith, and numerous species of insects. The rock spider has been mentioned, and termites also. Termites, incidentally, are extremely important to the ecology of the forest. In their feeding they break down and destroy the branches and trunks of fallen trees. The termite dust,  thereafter, by the action of bacteria, is reduced to humus, and the humus to nitrogen and mineral materials.

Yellow Breasted Hermit
a bird of the Northern Forest, it beats with a sharp beak against trees, such as the Tur tree,  to hunt for larvae.

Somewhere, far off, but carrying through the forest, was the rapid, stacaccato slap of the sharp beak of the yellow-breasted hermit bird, pounding into the reddish bark of the tur tree, hunting for larvae.

Zad
a large, broad-winged, black &- white bird with a long, narrow, yellowish, hooked beak, found in the Tahari, they  scavenge on carrion, similar to the Earth vulture

I heard, a short time later, wings, the alighting of one of more large birds.  Such birds, broad-winged, black and white, from afar, follow the marches to Klima; their beaks, yellowish, narrow, are long and slightly hooked at the end, useful for probing and tearing.
The birds scattered, squawking, as a Kaiila sped past.  The birds are called zads.
Tribesmen of Gor Page 232

Zad, Jungle
A cousin of the Tahari zad but less aggressive, found in the rain forest inland of Schendi,  yellow-winged, scavenging birds with long, yellowish, slightly curved beaks About some of these bodies there circles scavenging birds.  One the shoulders of some perched small, yellow-wingers jards.  One was even attacked by zads, clinging to it and tearing it with their long, yellowish, slightly curved beaks.  These were jungle zads.  They are to be less feared then desert zads, I believe being less aggressive.  They do, however, share one ugly habit with the desert zad, that of tearing out the eyes of weakened victims.  That serves as a practical guarantee that the victim, usually an animal, will die.  Portions of flesh the zad will swallow and carry back to its nest, where it will disgorge the flesh into the beaks of its fledglings.  The zad is, in its way, a dutiful parent.

Zadit
a small, tawny feathered, sharp- billed bird of the Tahari, insectivorous, feeding on sand flies and other similar insects, they often land a kaiila and spend long periods hunting the sand  flies that infest the host animal A bird of the Tahari. Feeds on the sand flies and other insects that infest the kaiila.
"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."
