In William Henry Hudson's Green Mansions,
his haunting romantic novel of the American tropics, the young hero Abel is
lured into the jungle by the mysterious call of an unseen bird. So stirred
is he by the "siren song" that he follows the haunting sound deeper and
deeper into the forest, until he eventually discovers the source: a lovely,
half-wild bird girl called Rima, who has learned to mimic the sounds of
the birds.

The bird life of Costa Rica is
so rich and so varied--and often so elusive--that at times it seems as if
Rima herself is calling.
With approximately 850 recorded bird species,
Costa Rica boasts one-tenth of the world's total. More than 630 are resident
species; the remainder are transients, who fly in for the winter. Birds
that have all but disappeared in other areas, still find tenuous safety in
protected lands in Costa Rica, though many species face extinction due to
deforestation.
The nation offers hope for such rare jewels of
the bird world as the quetzal and the scarlet macaw, both endangered
species yet commonly seen in protected reserves.

BIRD WATCHING
Fortunately, Costa Rica's birds are not shy.
Seeing them is relatively easy. Depending on season, location, and luck,
you can expect to see many dozens of species on any one day. Many tour
companies offer guided bird-study tours, and the country is well set up
with mountain and jungle lodges which specialize in bird watching
programs.
The deep heart of the jungle is not the best
place to look for birds: you cannot see well amid the complex,
disorganized patterns cast by shadow and light. For best results, find a
large clearing on the fringe of the forest, or a watercourse where birds
are sure to be found in abundance.
There are four major "avifaunal zones," which
roughly correspond to the major geographic subdivisions of the country:
the northern Pacific lowlands, the southern Pacific lowlands, the
Caribbean lowlands, and the interior highlands. Guanacaste's dry habitats
(northern Pacific lowlands) share relatively few species with other parts
of the country. This is a superlative place, however, for waterfowl: the
estuaries, swamps, and lagoons which make up the Tempisque Basin support
the richest freshwater avifauna in all Central America, and Palo Verde
National Park, at the mouth of the Tempisque, is a birdwatcher's Mecca.

The southern Pacific lowland region is home to
many South American neotropical species, such as jacamars, antbirds, and,
of course, parrots. Here, within the dense forests, the air is cool and
dank and underwater green and alive with the sounds of birds.
In fact, many birds are easily heard but not
seen. The three-wattled bellbird, which inhabits the cloud forests, is
rarely spotted in the mist-shrouded treetops, though the male's eerie
call, described by one writer as a "ventriloqual `bonk!'" (it is more like
a hammer clanging on an anvil), haunts the forest as long as the sun is
up. And the lunatic laughter that goes on compulsively at dusk in lowland
jungles is the laughing falcon.
Fortunately other species, like the tanagers,
brighten the jungle, and you are likely to spot their bright plumage as
you hike along trails. The tanagers' short stubby wings enable them to
swerve and dodge at high speed through the undergrowth as they chase after
insects.

The sheer size of Costa Rica's bird population
has prompted some intriguing food-gathering methods. The jacamar snaps up
insects on the wing with an audible click of its beak. One species of
epicurean kite has a bill like an escargot fork, which it uses to pick
snails from their shells. The attila, like its namesake a ruthless killer,
devours its frog victims whole after bashing them against a tree.

Other birds you might expect to see, include the
boobies, the rare
harpy eagle,
(the largest of all eagles, renowned for twisting and diving through the
treetops in pursuit of monkeys), pelicans, parakeets, oropendolas,
woodpeckers, and a host of birds you may not recognize, but whose names
you will never forget: scarlet-thighed dacnis, violaceous trogons, tody
motmots, laneolated monlets, lineated foliage-gleaners, and black-capped
pygmy tyrants.

Toucans
The bright-billed toucans--"flying bananas"--are
a particular delight to watch as they pick fruit off one at a time with
their long beaks, throw them in the air and catch them at the back of
their throats. Costa Rica's six toucan species are among the most
flamboyant of all Central American birds. That loud frog like croak is the
Swainson's toucan; that noisy jumble of cries and piercing creaks could
well be a congregation of gregarious chestnut-mandibled toucans.

Toucans are for the true bird enthusiast. With
their long, colorful beaks, and their animated personality, they are truly
the "elite" of the bird kingdom. From the large Toco's, to the tiny
Toucanette's, and Aracari's, all Toucans are truly wondrous creatures. You
have not experienced true "birdy love", until you have a really tame baby
Toucan purr in your lap, and beg to be played with! The combination of a
shorter than parrot lifespan (about 20 - 25 years), no more commercial
importation, and lack of people breeding them, had caused hand raised baby
Toucans to be extremely hard to find, there are only a handful of us
breeders in the US.

Toucans require a diet based on fruit. Period.
Toucans do not drink much water, preferring to use it to bathe in, and
they can become dehydrated, and build up too much iron in their system if
not fed enough fruit. Papaya is my main ingredient, along with grapes,
apple, melons, frozen blue berries, and whatever other non citrus fruit is
available. All fruits are chopped finely, and fed daily. Toucans are
highly prone to hemochromotosis, or iron storage disease, so a low iron
diet is a must. A source of protein must be offered.
The most popular of the Toucans is
the Toco (Ramphastos toco). It has a black body, white bib and bright blue
eye ring. It's bill is generally golden orange with a large black spot at
the end. The toco measures about 22 inches long and has a 10-inch-long
bill. The Red Bill (R. Tucanus), approximately 20 inches long, is mostly
black with a white bib, ending in a rim of red around the bib. The bill is
black with dark red in the middle of each mandible. The Keel Bill (R.
Sulfuratus), approximately 16 inches long, has a black body, yellow bib
and red vent. The bill is bright yellow, pastel green and red at the tip.
The Channel Bill (R. Vitellinus) has a black body with a white and yellow
bib. The bill is solid black except for a blue band close to the face. The
channel bill is approximately 18 inches long.
Toucans belong to the softbill
family, despite the fact that their bills are definitely not soft. Their
bills are also not as heavy as they look; they are made from a porous
honeycomb type material and are very sensitive. Hand-fed toucans can make
tame and loving pets, and may live up to 20 years. Toucans do not talk,
instead they make a croaking-type sound, or they make a purring-like sound
when they are contented.
Even though this group of birds is
from the tropics, they need shade, especially if temperatures go above 90
degrees Fahrenheit. In that case, it is even more important that these
birds receive showers or have a bathing dish. If you keep a single toucan
in a cage, a large macaw cage of at least 4 feet long is appropriate. If
you keep the birds in an aviary, consider one 7 by 10 by 7 feet. Keep in
mind that these are extremely active birds that need plenty of room and
perches to jump and run.

Toucans make their homes in holes in
trees. They usually live in pairs or small flocks. White, glossy eggs are
laid once a year and when they hatch, the new chicks have no down covering
them. When they sleep, they turn thier heads around and tuck their bills
under their wings and tail. The toucan is very important to the rainforest
because they help to disperse seeds from the fruits and berries they eat.

HUMMINGBIRDS
Of all the exotically named bird species in Costa
Rica, the hummingbirds beat all contenders. Their names are poetry: the
green-crowned brilliant, purple-throated mountaingem, Buffon's plummeteer,
and the bold and strikingly beautiful fiery-throated hummingbird. There
are more than 300 species of New World hummingbirds constituting the
family Trochilidae (Costa Rica has 51), and all are stunningly pretty.

The fiery-throated hummingbird, for example, is a
glossy green, shimmering iridescent at close range, with dark blue tail,
violet-blue chest, glittering coppery orange throat, and a brilliant blue
crown set off by velvety black on the sides and back of the head. Some
males take their exotic plumage one step further and are bedecked with
long streamer tails and iridescent mustaches, beards, and visors.
These tiny high-speed machines are named because
of the hum made by the beat of their wings. At up to 100 beats per second,
the hummingbirds' wings move so rapidly that the naked eye cannot detect
them. They are often seen hovering at flowers, from which they extract
nectar and often insects with their long, hollow, and extensile tongues
forked at the tip. Alone among birds, they can generate power on both the
forward and backward wing strokes, a distinction that allows them to even
fly backwards!

Understandably, the energy required to function
at such an intense pitch is prodigious. The hummingbird has the highest
metabolic rate per unit of body weight in the avian world (its pulse rate
can exceed 1,200 beats a minute) and requires proportionately large
amounts of food. One biologist discovered that the white-eared hummingbird
consumes up to 850% of its own weight in food and water each day. At
night, they go into "hibernation," lowering their body temperatures and
metabolism to conserve energy.

Typically loners, hummingbirds bond with the
opposite sex only for the few seconds it takes to mate. Many, such as the
fiery-throated hummingbird, are fiercely territorial. With luck you might
witness a spectacular aerial battle between males defending their
territories. In breeding season, the males "possess" territories rich in
flowers attractive to females: the latter gains an ample food source in
exchange for offering the male sole paternity rights. Nests are often no
larger than a thimble, loosely woven with cobwebs and flecks of bark and
lined with silky plant down. Inside, the female will lay two eggs no
larger than coffee beans.


MACAWS
What magnificent creatures these birds are. No
protective coloration. No creeping about trying to blend in with the
countryside. Macaws--the largest of the neotropical parrots--are
dazzlingly colored in jackets of bright yellow and blue, green, or
scarlet. Their harsh, raucous voices are filled with authority. "Even
moving from branch to branch in the treetops," says one writer, "they seem
arrogant and proud as emperors."

Although macaw is the common name for any of 15
species of these large, long-tailed birds found throughout Central and
South America, only two species inhabit Costa Rica: the scarlet macaw (lapa
roja) and the great green or Buffon's macaw (lapa verde).
Though the scarlet ranges from Mexico to central
South America and was once abundant on both coasts of Costa Rica, today it
is found only in a few parks on the Pacific shore, and rarely on the
Caribbean side, which is the home of the Buffon's macaw. Both bird
populations are losing their homes to deforestation and poaching.

The scarlet macaw population, has declined so
dramatically, that it is now in danger of disappearing completely: there
are only three wild populations in Central America that have a long-term
chance of survival--at Carara Biological Reserve and Corcovado in Costa
Rica, and Coiba Island in Panama--although macaws can also be seen with
regularity at Palo Verde National Park, Santa Rosa National Park, and
other forested parts of the Gulf of Nicoya and Osa Peninsula.
There are an estimated 200 scarlets at Carara and
1,600 at Corcovado, where as many as 40 may be seen at one time.
As they fly overhead, calling loudly, their long,
trailing tail feathers and short wings make it impossible to confuse them
with other birds. They are gregarious and rarely seen alone. They are
almost always paired male and female--they're monogamous for life--often
sitting side by side, grooming and preening each other, and conversing in
rasping loving tones, or flying two by two. However, it is impossible to
tell male from female. The scarlet's bright red-orange plumage with
touches of blue and yellow does not vary between the sexes or with aging.

Macaws usually nest in softwood trees, such as
jallinazos, where termites have hollowed out holes. April through July,
you might see small groups of macaws clambering about the upper trunks of
dead trees at Corcovado, squabbling over holes and crevices. In Carara,
nesting season begins in September.
Many bird books mistakenly describe macaws as
feeding on fruits--they get their names because they supposedly feed on
the fruits of the macaw palms. In fact, they rarely eat fruits, but prefer
seeds and nuts, which they extract with a hooked nutcracker of such
strength that it can split that most intractable of nuts, the Brazil nut.
Macaw Protection
Several conservation groups are working to
stabilize and reestablish the scarlet and green macaw population. Deep in
the forest of the Carara Biological Reserve, Sergio Volio (a former
national park superintendent, and owner of Geotur), oversees a project to
build artificial nests high up in jallinazo trees beyond the reach of
poachers. Although macaws are the biggest attraction at Carara, they are
threatened with extinction by poachers who take the chicks to sell on the
black market in the U.S., despite a ban that prohibits importing the
birds.
Most die, however, before they reach the United
States. Volio estimates up to 95% of natural nests at the reserve are
poached. Volio's is the first project that will protect the birds'
breeding grounds in their natural habitat. He is currently forming a
foundation to accept donations to help build the birdhouses, which cost
about $100. Contact: Geotur, P.O. Box 469Y Griegia, San José 1011;
tel. 234-1867, fax 253-6338.
Tsuli/Tsuli, an
independent, self-supporting chapter of the Audubon Society, has an Adopte
un Ave (Adopt-a-Bird) program. Tsuli/Tsuli means "Many Parrots" in the
language of the Cabécar Indians. The group has an environmental education
program to teach local Costa Ricans to understand and appreciate their
flora and fauna, with a special emphasis on protecting birds, especially
parrots, which are symbols of tropical wilderness. Contact: Tsuli/Tsuli,

249-1179; or P.O. Box 025216-700, Miami, FL 33102.
Tsuli Tsuli supports Richard and Marge Frisius,
two experienced aviculturists who have a macaw-breeding program on the
grounds of their home in Río Segundo de Alajuela. The Frisiuses have
successfully raised many baby macaws using special techniques and cages.
By teaching the domestically raised macaws how to find native food and
then releasing them into carefully selected wilds of Costa Rica, the goal
is to reestablish flocks of these magnificent birds in parts of the nation
where there is still appropriate habitat for viable populations to
establish themselves.
The Frisiuses need at least 15 breeding pairs of
macaws to establish a large gene pool. They also need to construct a large
cage in which the birds can fly and forage freely (approximate cost
$75,000). The couple have formed their own nonprofit organization,
Amigos de las Aves, to raise money (send donations to: Apdo. 32, Río
Segundo 4001).

QUETZALS

The quetzal, or resplendent trogon, is a rare
jewel of the bird world. Many bird watchers travel to Costa Rica simply to
catch site of this magnificent bird. What this pigeon-sized bird lacks in
physical stature it makes up for in audacious plumage: vivid, shimmering
green which ignites in the sunshine, flashing emerald to golden and back
to iridescent green. In common with other bird species, the male outshines
the female. He sports a fuzzy pink punk hairdo, a scintillating crimson
belly, and two brilliant green tail plumes up to 24 inches long, edged in
snowy white and sinuous as feather boas.
Its beauty was so fabled and the bird so elusive
and shy that early European naturalists believed the quetzal was a
fabrication of Central American natives. In 1861, an English naturalist,
Osbert Salvin, wrote that he was "determined, rain or no rain, to be off
to the mountain forests in search of quetzals, to see and shoot the
elusive quetzal, which has been a daydream for me ever since I set foot in
Central America."
Salvin, the first European to record observing a
quetzal, pronounced it "unequaled for splendor among the birds of the New
World," and promptly shot it. During the course of the next three decades,
thousands of quetzal plumes crossed the Atlantic to fill the specimen
cabinets of European collectors and adorn the fashionable milliners' shops
of Paris, Amsterdam, and London. Salvin redeemed himself by authoring the
awesome 40-volume tome Biologia Centrali Americana, which provided
virtually a complete catalog of neotropical species.
Quetzal Culture

The quetzal has long been revered in Guatemala,
where the bird graces the national shield, flag, postage stamps, and
currency (which happens to be called the quetzal). It is pleasing
to know that the former center of the Mayan empire still honors the
magnificent bird. Early Mayans and Aztecs worshipped a god called
Quetzalcoatl, the Plumed Serpent, and depicted him with a headdress of
quetzal feathers. The bird's name is derived from quetzalli, an
Aztec word meaning "precious" or "beautiful."
Mayans considered the male's iridescent green
tail feathers worth more than gold, and killing the sacred bird was a
capital crime. Quetzal plumes and jade, which were traded throughout Meso
America, were the Mayans' most precious objects. It was the color that was
significant: "Green--the color of water, the life giving fluid. Green, the
color of the maize crop, had special significance to the people," says
Adrian Digby in his monograph Mayan Jades, "and both jade and the
feathers of the quetzal were green."
During the colonial period, the indigenous people
of Central America came to see the quetzal as a symbol of independence and
freedom. Popular folklore relates how the quetzal got its dazzling,
blood-red breast: in 1524, when the Spanish conquistador Pedro de
Alvarado, defeated the Mayan chieftain Tecun Uman, a gilt-and-green
quetzal alighted on the Indian's chest at the moment he fell mortally
wounded; when the bird took off again, his breast was stained with the
brilliant crimson blood of the Mayan.
Archaeologists believe that the wearing of
quetzal plumes was proscribed, under pain of death, for use by Mayan
priests and nobility: it became a symbol of authority vested in a
theocratic elite, much as only Roman nobility were allowed to wear purple
silks.
Quetzal Watching
Although Costa Ricans don't worship the quetzal
with the same fervor as pre-Columbian Guatemalans, the bird is most easily
seen in Costa Rica, where it is protected in four national parks--Braulio
Carrillo, Poás, Chirripó, La Amistad--and the Monteverde and Los Angeles
cloud forest reserves.
Everywhere throughout its 1,000-mile range (from
southern Mexico to western Panama) it is endangered due to loss of its
cloud-forest habitat. This is particularly true of the lower forests
around 1,500 to 2,000 meters to which families of quetzals descend during
breeding season (March-June), and where they seek dead and decaying trees
in which to hollow out their nests.

This is the best time to see narcissistic males
showing off their tail plumes in undulating flight, or launching spiraling
skyward flights which presage a plummeting dive with their tail feathers
rippling behind, all part of the courtship ritual.
At other times, the wary birds aren't easily
spotted. Their plumage offers excellent camouflage under the rainy forest
canopy. They also sit motionless for long periods, with their vibrant red
chests turned away from any suspected danger. If a quetzal knows you're
close by and feels threatened, you may hear a harsh weec-weec
warning call, and see the male's flicking tail feathers betray his
presence.
The quetzal's territory spans a radius of
approximately 300 meters, which the male proclaims each dawn through
midmorning and again at dusk with a telltale melodious whistle--a hollow,
high-pitched call of two notes, one ascending steeply, the other
descending--repeated every eight to 10 minutes.
Nest holes (often hollowed out by woodpeckers)
are generally about 30 feet from the ground. Within, the female generally
lays two light-blue eggs, which take about 18 days to hatch. Both sexes
share parental duties. By day, the male incubates the eggs while his
two-foot-long tail feathers hang out of the nest. At night, the female
takes over.
Although the quetzal eats insects, small frogs,
and lizards, it enjoys a penchant for the fruit of the broad-leafed
aguacatillo (a kind of miniature avocado in the laurel family), which
depends on the bird to distribute seeds. The movement of quetzals follows
the seasonal fruiting of different laurel species. Time your bird watching
visit, if possible, to coincide with the quetzals' rather meticulous
feeding hours, which you can almost set your watch by. They're fascinating
to watch feeding: an upward swoop for fruit is the bird's aerial
signature.

FRIGATE BIRDS
Black frigate birds, with their long scimitar
wings and forked tails, hang like sinister kites in the wind all along the
Costa Rican coast. They hold a single position in the sky, as if suspended
from invisible strings, and from this airborne perch harry gulls and terns
until the latter release their catch (birders have a name for such
thievery: kleptoparasitism).
Despite the sinister look imparted by its long
hooked beak, the frigate bird is quite beautiful. The adult male is all
black with a lustrous faint purplish-green sheen on its back (especially
during the courtship season). The female, the much larger of the two, is
easily distinguished by the white feathers that extend up her abdomen and
the breast, and the ring of bluish mascara she wears around her eyes.

Second only to a frigate bird's concern for food
is its interest in the opposite sex. It is the females who do the
conspicuous searching out and selecting of mates. The hens take to the air
above the rookery to look over the males, who cluster in groups atop the
scrubby mangrove bushes. Whenever a female circles low over the bushes,
the males react with a blatant display of wooing: they tilt their heads
far back to show off their fully inflated scarlet gular pouches
(appropriately shaped like hearts!), they vibrate their wings rapidly back
and forth, and entice the females with loud clicking and drumming sounds.
To walk through a colony of frigate birds
courting is a spellbinding experience; the lusty atmosphere is palpable.
You may even see pairs entwined, the male with his wings around his mate.
Once the pair is established, a honeymoon of
nest-building begins. In the structured world of the frigate bird's it is
the male's job to find twigs for the nest. The piratical frigates will not
hesitate to steal twigs from their neighbors' nests, so the females stay
home to guard it.
A single egg is laid, and each parent takes turns
at one-week shifts during the eight-week incubation. The chick is closely
guarded, for predatory neighbors, hawks, and owls make quick feasts of the
unwary young. For five months, the dejected-looking youngsters sit
immobile beneath the hot sun; even when finally airborne, they remain
dependent on their parents for over a year while they learn the complex
trade of air piracy.
Superb stunt flyers, frigate birds often bully
other birds on the wing, pulling at their tails of their victims until the
latter release or regurgitate a freshly caught meal. Frigate birds also
catch much of their food themselves. You may see them skimming the water,
snapping up squid, flying fish, and other morsels off the water surface.
(They must keep themselves dry, as they have only a small preen gland,
insufficient to oil their feathers; if they get too wet they become
waterlogged and drown.)
Frigate birds are easily seen close-up en masse
along the mangrove-lined shorelines of Guanacaste and the Gulf of Nicoya, sunning themselves, often in a near vertical position with wings turned
"palm up."

Bird Books
The two best "Birding" books to buy are: " A
Guide to the Birds of Costa Rica"
by Gary Stiles and Alexander Skutch, and "Travel
& Site Guide to Birds of Costa Rica With Side Trips to Panama"
by Aaron Sekerak. The second book has excellent coverage of where to go in
Costa Rica, what can be seen, and a comprehensive breakdown of
distribution by region.
