Day
1. Caracas-Mérida.
Arrival to Maiquetía International Airport, Caracas. Transfer
to Mérida. Reception by Tour Leader. Hotel registration. Personal
introduction of tourists and guides with comments on respective interests.
Slide show of sites and species that you will most probably get to know
in the survey.
Day 2. Mérida-Maracaibo
lake.
The team will head to southern area of Maracaibo lake, the largest
lake in South America and main axis of oil industry in Venezuela. We will
navigate within mangrove coves, where there is a dense population of red
howler monkey (Alouatta senicula). Capucin monkeys (Cebus)
are also possible to observe. A varied array of bird communities are also
conspicuous, including Amazon Parrots, Chestnut fronted Macaws, large Rhamphastos
toucans, and one of the rarest birds in Venezuela, the
Northern
Screamer (Chauna chavaria). It is almost guaranteed to see estuarine
Dolphins (Sotalia fluviatilis) playing close to us. Even much rarer,
but not impossible would be to see the Caribbean Manatee (Trichechus
manatus), one of the most endangered mammals in the country. Green
Iguanas (Iguana iguana) are going to be faithful companions during
all visits to the lowlands. At night, in an additional boat trip we will
see how nocturnal life takes over. This is time to see Caimans (Caiman
crocodylus fuscus), the Mangrove Boa (Corallus ruschenbergerii),
Boa constrictor and endemic frogs such as Hyla vigilans.
Day 3. Maracaibo Lake basin.
We will go to an Hacienda in the savanna, used primarily for
raising cattle. In the myriad of lagoons, we will be able to easily see
two species of freshwater turtles, one endemic to Maracaibo basin, Rhinoclemys
diademata, and the other that is widespread in the Neotropics, Kinosternon
scorpioides. A further species is also endemic to a localized lagoon area
nearby, but it is a rare sight, Phrynops zuliae. In the savanna there is
also Red footed Tortoise, Geochelone carbonaria, but it is progressively
becoming rarer due to uncontrolled human poaching. Water Snakes in the
genus Helicops as well as other serpents typical of the savanna are easy
to observe: Mastigodryas, Liophis melanotus, Spilotes pullatus, Oxybelis
aeneus, Imantodes cenchoa, Leptodeira annulata, as well as Iguanas, Ameiva
and Cnemidophorus lizards, diurnal Gonatodes Geckos... among many other
reptiles. At night, and around human housings, we could be surprised to
see the largest Gecko in America, Thecadactylus rapicauda, and a variety
of Anurans, Bufo marinus, B. granulosus, Hyla crepitans, H. microcephala,
Phrynohyas venulosa, Leptodactylus bolivianus, Pseudopaludicola pusilla,
the endemic Pipa parva, as well as adults and huge tadpoles of Pseudis
paradoxa. The zone is also home of other hard to find amphibians, like
Ceratophrys calcarata, and the Caecilian Nectocaecilia haydeeae.
Day
4. Maracaibo basin-Andes.
Now it will be time to survey the alluvial zone of the Chama
river, where we could find Basilisks lizards (Basiliscus basiliscus),
and perhaps Cocodrylus acutus. Perhaps this is also the finest place to
see South American otter (Lontra longicaudis). Afterwards, we will
move to an important migratory pass for birds that come from or return
to North America, where it is possible to see, at the appropriate time,
thousands of birds belonging to hundreds of species. This is the habitat
of one of the largest and most beautiful Tarantula species in the Neotropics,
Xenestis monstrosa. Later, we will ascend to the Andes, where we will witness
the transition into the cloud forest at 1400 meters. At night we will search
for frogs like Hyla minuta, H. luteoocellata, H. crepitans; and Atractus
snakes. With some luck we will see Onycophorans, Peripatus the living arthropod
fossil, under logs, stones and debris.
Day 5. Andes.
In the morning, we will continue herping. Back to Mérida,
we will stop in a Colonial Hacienda, where we will learn ancestral techniques
for the processing of coffee, a long time important economical item of
the region. Riding back into the Andes, through the arid valley of the
Chama river, we will stop to see local herps, within the forest of huge
Candlestick Cacti. There, Micrurus meridensis is a worthwhile finding,
although Drymarchon corais melanurus, Pseudoboa neuwiedii, Crotalus sp.,
Green Iguanas, Ameiva bifrontata and Cnemidophorus
lizards are amongst the pretty elements of fauna in the region. Also, this
is a site where Tamandua anteater (Tamandua mexicana) is not particularly
rare to see. Finally, we will stay overnight at the peaceful and picturesque
Mérida, the Andean capital city lying below perennial snow capped
mountain peaks surpassing 5000 meters (15000 ft).
Day 6. Andes
Visit to Teleférico de Mérida, the longest (12
½ Kms) and highest (4765 m) cable car in the world. During the ascent,
it is possible to see four different types of ecosystems:
1. Cloud forest, 2. Dwarf high altitude forest, 3. Páramo,
and 4. Andean nivel belt. Once at the summits, we will trek for Páramo
recognition. Back to Mérida. Off duty afternoon for free-will activities
(shopping, cinema, salsa and merengue dancing ...). Optional herping in
a nearby pristine cloud forest, where local species are worthy: Hyla jahni,
Eleutherodactylus vanadisae, Gastrotheca nicefori and some glass-frogs
(Centrolene and Hyalinobatrachium).
Day 7. Andes
Depart to explore the Andean cloud forest, habitat of Andean
Salamander Bolitoglossa orestes, among other herps. We w
ill
continue to Páramo environment, where walking silently alongside
enchanted and beautiful glacial lagoons, where Páramo Rabbits (Sylvilagus
brasiliensis meridanus) and Andean deer (Odocoileus goudotti)
thrive. This is the habitat of frogs highly adapted to cold weather, namely
Eleutherodactylus ginesi (an evolutionary convergent of high tepuian Bufonid
in the genus Oreophrynella), E. lancinii, Colostethus leopardalis and Atelopus
mucubajiensis. This last species, as well as all Venezuelan Harlequin Toads,
has suffered severe population declines, to the point, where no one has
reported any living animal in the past five years, thus scientific community
fears that this species has become extinct. One of our goals will be to
systematically survey the area, with the hope to rediscover and report
it. We will continue our exploration in the Páramo, paying particular
attention to the decomposing matter of Espeletias (Rosette-like bush with
oblong leafs covered with plenty cotton-like coating, native to high altitude
Andes in Venezuela south to Ecuador). Within these, several amphibians
takes refugee, and also Microteiids Anadia lizards. Later in the day, we
will take a chance to visit the Andean Condor (Vultur gryphus) reintroduction
and conservation facilities, and we will explore its habitat to admire
the magnificent and majestic flight of the largest flying bird of the world.
Day 8. Andes
During the morning we will freshen ourselves up, and recover
energies, while bathing in a hot spring with magnificent views. Back on
duty, a wild river will flank us along the road, stopping to see an endangered
bird, the Torrent Duck (Merganetta armata colombiana). A splendid
cloud forest will be the stage to see one of the Neotropics most magnificent
spectacles, the nuptial display of fiery red Andean Cock-of-the Rock
(Rupicola
peruviana). Herps are also abundant here and it is possible to find
Micrurus mipartitus, Erythroplamprus bizona, Lampropeltis triangulum andesina...
We will witness the abundance of the diurnal dendrobatid Mannophryne collaris.
Some anurans are very abundant at the foothills of the Andes and surroundings,
notably Bufo marinus, B. granulosus, Pleurodema brachyops, H. microcephala,
Hyla lanciformis, Hyla punctata, Scinax rostrata, Physalaemus pustulosus,
Leptodactylus macrosternum and maybe Phyllomedusa hypocondrialis.
Day 9. Departure
Farewell meeting. Flight to Caracas and connection to origin
or link to the Llanos tour.
