Other native trees are relatively small and of no value as timber although the lignum vitae is cherished for the manufacture of small wooden articles. The most numerous of the small unidentified trees are characterized by multitudinous thin branches, scantily leaved. Except in sheltered areas the tips of the branches are bare and white, denuded by the trade winds which lash the Base from January to April. Trees on hillsides adjacent to the sea have a permanent landward tilt to their tops.
Along the beaches, sea grape trees are numerous. These trees never grow to a great height. They have almost circular leaves and grape-like bunches of berries from which jelly can be made. Edging the inlets of the Bay and bordering the Guantánamo River for several miles from its mouth are mangrove trees which, in places, form almost impenetrable "jungle".
Many trees native to Cuba and other West Indian islands have been transplanted to the Base and have prospered by dint of generous watering. These include the stately and beautiful Royal Palm, coconut palms, and dinner palms. A small thatch palm native to the Base adds a picturesque touch.
Cacti: The Royal Poinciana, named for M. de Poinciana, a former governor of the French West Indies has been widely planted. In May and June the bare branches of the tree become a mass of flame-colored blossoms. The Cubans call this tree Flamboyan (Flamboyant).
Exotic tropical fruits thrive on the Base, particularly several varieties of mangoes. Esteemed by many, mangoes cause some individuals to break out in a painful rash which may require hospital care. Avocado, papaya, banana, orange, and grapefruit trees offer fruits to suit any taste. Sweet-sops (a kind of sugar apple), soursops, guavas, and pomegranates grow on the Base but are not as important to residents as the limes which also grow at Guantánamo and are so refreshing in cooling drinks.
Flowering shrubs which in their season paint the surroundings of the quarters in vivid colors include white and pink oleander, red poinsettia, several varieties of hibiscus, and bougainvillea in colors ranging from rich purple to deep crimson. A shrub with leaves almost as colorful as flowers is the croton, widely planted on the base in a variety of colors. Nightblooming jasmine, frangipani, and a species of gardenia give the air a special fragrance. Following the rainy season a small ground vine covers the lawns with a primrose-like yellow flower which later forms a prickly seed.
The most prevalent forms of plant life on the Base are the many varieties of cacti which flourish in all uncultivated areas.
Other birds common to the Base include the Western Red-Legged Thrush, Greater Antillean Oriole, Stolid Flycatcher, Belted Kingfisher, Cuban Woodpecker, and West Indian Red-Bellied Woodpecker. One bird nearly always evident is the Turkey Vulture. Others are the Cuban Blackbird, Red-winged Blackbird, and the Tawny-shouldered Blackbird; the American Redstart, the Palm Warbler and the Black and White Warbler.
In addition to the Mourning Dove, there are White-winged Doves and Turtle Doves in abundance. During June and July, White-crowned Pigeons flock to the mangrove islands in the Bay to nest and raise their young.
The Brown Pelican, Anhinga, Magnificent Frigatebird, and several species of gulls and terns are common at Guantánamo Bay, seen elsewhere chiefly through the pages of Birds of the West Indies,by James Bond, a volume which is in great demand at the Base Library. Canadian Geese are known to migrate there between December and February.
A species of boa constrictor, the Maja, reaches a length of ten feet or more and a number have been killed on the Base. The maja is non-poisonous, and apparently harmless to man, as are the other smaller snakes found on the Base. Cuba has no poisonous snakes. Bites from these boas are uncommon, but the same cannot be said of mosquitoes and sand flies, which at certain seasons make outdoor life after sundown miserable.
It would seem reasonable to suppose that fishing would be good at Guantánamo Bay, the vast expanse of the Bay itself, the Guantánamo river, and the Caribbean Sea offering unlimited opportunities for the angler.
Unfortunately, the fishing is not exceptional. One of the contributing factors to its mediocrity is the offshore shelf, which is so precipitous that the shallows and reefs so desirable for good fishing are notably absent.
Despite the adverse factors mentioned, there is a great variety of fish in local waters, and persistent anglers make many worthwhile catches.
Sea turtle Most common game fish include the Great Barracuda, Tarpon, Kingfish, Jack, Snook, and several kinds of Snappers and Groupers. Snappers weighing more than 80 pounds (36 kg) have been landed at the mouth of the Guantánamo River, a favorite spot for Snapper fishing. Wahoo, Cobia, Pompano, Arctic Bonito, Falso Albacore, and even a few Sailfish have been caught in waters adjacent to the Base.
Several kinds of Sharks, including the Hammerhead, frequent the Bay and adjacent waters, as do several species of rays. Smaller fish include the mangrove snapper, trigger fish, parrot fish, angel fish, bonefish, and many others.
Langosta Porpoise are common in the Bay, and Manatees (sea cows) have been seen in the upper reaches of the river. Sea Turtles are often observed at the surface of the water not far from shore, and many are captured as they come ashore at night at the beaches to lay their eggs.
The Langosta, a spiny lobster, is abundant in the Bay, and fishing for langostas is a favorite sport.
Alligators are sometimes sighted in the river and in the mangrove labyrinths of the upper Bay, but they are undoubtedly not so common now as in the days when they gave the town of Caimanera, Cuba its name.
