    Rare Sightings in the transition to the hot

    Season

    A pick of the best from May and June 2012

    The current transition to the hot season has not been as theoretically expected. There have

    been high rainfalls, with the consequents increases of the river level. The cold period of times

    called “friajes” have also appeared. However, in this transition time, many rare sightings

    species were seen and found. Here we emphasize which, in our opinion, were the most

    important sightings:

    Red worn lizard (Amphisbaena alba). Order: Squamata, Family: Amphisbaenidae

    It is widespread in South America and it is

    common in a wide variety of habitats including

    altered and disturbed habitats. But however, it is

    not easily spotted. Despite of it, RN Luís, while

    walking through Terrace trail, he suddenly saw

    something that looked like a snake. But when

    glancing it closer, and after taking a few

    pictures, he could identify this shy reptile.

    Harpy Eagle (Harpia harpyja). Order: Falconiformes, Family: Accipitridae

    This eagle is the largest one all over the world, and it possesses the hugest claws among all

    the birds of prey. It is found in

    tropical lowland forest, with

    preference on large expanses of

    uninterrupted forest, hunting in open

    areas adjacent to forest patches.

    Despite of its size, it is uncommon to

    see it. But on May 20th, when coming

    back from Collpita clay lick, 200m

    away from Explorer’s Inn in

    Tambopata River, RNs Pablo and

    Luis had the privilege to see this

    wonderful and uncommon adult bird

    flying cross the river. It was such a

    great sight, that the boat almost turns

    upside down!

    Jaguar (Panthera onca). Order:Carnivores, Family:Felidae

    Jaguars are usually found resting on

    the rivers banks, and most of the

    sightings are from the boat. But on

    May 2nd

    , Explorers Inn guide Lucho

    and two Australian tourists had an

    unforgettable experience. While

    walking around Colpa Chuncho,

    they first spotted about hundred of

    White-lipped Peccaries. After a few

    meters, they saw a group of Brown

    Capuchin Monkeys. It was being a

    great walk. But they were not yet

    satisfied. After walking 200m away

    from the monkeys, Lucho heard

    again the monkeys, but now they were kind of altered. Once they got back where the

    monkeys were, they perceived a movement on a branches 7m far from them. And suddenly it

    showed up: a big majestic adult jaguar. It did not look at them. Lucho felt really excited but

    he stayed with machete. Their happiness was very huge, in such a way they were not able to

    take any pictures! When it left, they hug each other, since it was one of the best sightings than

    a single person can experience. As Lucho has recognized, “it has been my 3rd

    time, but this

    time was with no doubt, the very best one!”

    The hoatzin: not a simple bird (by RN Albert Cámara)

    In your visits to Cocococha Lake to see the famous giant otters, other species might have required your

    attention.

    Maybe it was because of its characteristic and noisy

    groan. Or maybe it was because of its outlandish

    appearance. Or even because of its stinky smell. But

    whatever the reason, I am sure you know what

    species I am talking about. It is the hoatzin

    (Opisthocommus hoazin), one of the weirdest and

    peculiar birds in the Amazon.

    It is a tropical bird which inhabits areas with slow-

    moving water such as oxbow lakes or sluggish rivers

    in Amazon and Orinoco basins. In suitable habitats,

    they are social animals, forming groups of 25-30

    individuals. Here, in the Tambopata National

    Reserve, it is possible to see them all around the

    Cocococha Lake.

    As you read above, it

    has a very outlandish

    appearance: robust and big body, long tail, blue skin on face

    around red eyes and a long ragged “Mohican” crest on the top of

    its small head, which make it looks like a really special bird.

    The hoatzin is a noisy species, with a large variety of calls,

    including groans, croaks, hisses and grunts. Common calls include

    hoarse coughing and grunting sounds, which make them easy to

    spot among the vegetation. Calls are used to maintain contact

    between individuals in groups: for warning off threats or by chicks

    begging for food.

    This animal has a digestive tract which is unique among birds,

    with an enlarge gut used for fermentation of vegetable manner,

    like the digestive system of mammalian ruminants. It feeds mainly

    on leaves (about an 80% of their diet), but also on fruits and on flowers. Its intestinal bacteria

    make fermentation of the food up to four times more than most of the birds. Hence, because

    of this bacterial fermentation and also because of aromatic compounds in the leaves they

    consume, the bird has an unpleasant (and particular) smell. I think that now you would guess

    why this bird is called “stinky bird”…

    But the rarest peculiarity of this tropical bird is the presence, only

    on the chicks, of claws on two of their wing digits. When these

    chicks feel threatened by a predator, they rapidly jump into the

    water, since they are actually good swimmers. In fact, adults never

    swim, and they do not possess these kinds of clawed wings, which

    are used by chicks to help them to climb up from the water back to

    the safety of the nest.

    The taxonomic position of this bird has been greatly debated, and

    it is still far from clear, mostly due to the claws on the wings. This

    feature has not been present in any other animal since the well-

    known Archaeopteryx (one of the first existing birds, about 120

    millions of years ago), in such a way the hoatzin has been

    previously related to the first existing birds. However, recently

    studies have demonstrated that the presence of claws on the

    Figure 1. Distribution map of the hoatzin

    Picture 1. Detailed face of the hoatzin

    Picture 2. Chick of Opisthocommus hoazín. The yellow circles show the claws on the wing digits.

    wings is an independent feature, primitive

    and unique, which has evolved separately

    and it does not fit with the general believe

    that the hoatzin is related to Archaeopteryx

    or that it is a living fossil.

    They have been also included in the orders

    of the Galliformes and even in the

    Gruiformes, Recent studies have related

    them to the order of the Cuculiformes.

    Some of these studies classified the hoatzin

    in the family of the cuckoos (F. Cuculidae),

    based on genetic analyses of proteins. This

    theory has also been greatly discussed,

    since the cuckoos have zygodactyls feet

    (two toes pointing forward, two toes

    pointing to the back), while the hoatzins have only one toe pointing to the back and the

    remaining three pointing forward. There have been other cladystic hypotheses that suggest

    that they are related to the same order than the cuckoos, but in the family of the

    Musophagidae. Anyway, nowadays, scientific community does not agree on their taxonomic

    classification.

    However, because of its distinctness it has been given its

    own family, the Opisthocomidae. Actually, in classic

    Latin, Opisthocommus means something like “wearing a

    long hair behind”, referring to its large crest.

    As you can see, there have been a lot of controversial

    about the taxonomic position of this tropical bird. Based

    on this information, what do you think about it? Is the

    hoatzin related to the first existing birds? Is it a living

    fossil? Or is it related to other families like some studies

    have recently suggested? And about the other

    peculiarities: did you feel their unpleasant smell? Do you

    think that the hoatzin really deserves to be called “stinky

    bird”?

    Next time you spot a hoatzin, you will know a lot about its life story. And remember: it is not

    a simple bird… it is such a special animal!!!

    LA OTRA VIDA DE LAS MARIPOSAS (por RN Laura

    Otero)

    Durante su estancia en el Explorer’s Inn no podrá evitar fijarse en unas criaturas mágicas que revolotean alrededor del albergue, los caminos, las orillas de los lagos y ríos. De hecho, el

    Explorer’s Inn tiene el honor de contar con el récord de número especies de mariposas en una

    zona, nada más y nada menos que ¡1.200!

    Las mariposas son unos insectos (Orden Lepidoptera) de una belleza que no pasa inadvertida,

    pero… ¿qué sabe sobre su otra vida?

    El ciclo de vida de una mariposa incluye la

    metamorfosis de larva (conocida como oruga)

    a pupa y de pupa a adulto. En la primera fase

    de su vida su único objetivo es acumular

    comida y energía para poder completar la

    pupación, por lo que básicamente, es una

    “máquina de comer”.

    La oruga generalmente se alimenta, con ayuda

    de sus poderosas mandíbulas, de sólo una o dos especies de plantas. En la selva, la mayoría de

    plantas producen sustancias tóxicas, pegajosas o indigestas para evitar ser atacadas por

    insectos herbívoros. La oruga tiene una serie de encimas que neutralizan las toxinas generadas

    por las plantas, pero sintetizar dichas encimas cuesta mucha energía. Es por esto por lo que

    tiende a especializarse en unas pocas especies de plantas.

    A medida que una planta va aumentando su defensa, la oruga

    debe producir más y más encima, creándose así una carrera

    armamentística entre ambas. Representando esta batalla

    tenemos a la oruga de la subfamilia Heliconiinae, que

    mantiene una interacción complicada con su planta anfitriona,

    la pasiflora. Las hembras de los helicónidos ponen los huevos

    en las hojas de la pasiflora, y ésta, para evitarlo, produce una

    serie de protuberancias en forma de huevos para que las

    hembras crean que la planta ya está ocupada y se vayan a otra.

    Con esta estrategia la planta se libra de un ejército de orugas.

    La selección natural favorece a la planta que fabrica el huevo

    más realista, pero por supuesto no todas las hembras se dejan

    engañar y consiguen poner sus huevos.

    Una vez que la oruga consigue encontrar una planta hospedadora de la cual poder alimentarse,

    debe enfrentarse a otro reto: no convertirse ella misma en

    comida. Para ello utilizan dos estrategias. La primera es el

    mimetismo, mediante la cual, intenta imitar a un objeto

    natural en particular. Imitan desde ramitas para confundirse

    con la vegetación a ojos u otras partes de animales más

    grandes para intimidar a sus enemigos. Los depredadores

    tienen que detectar cada vez mejor el engaño para poder

    alimentarse y la oruga debe convertirse cada vez mejor en el

    objeto que imita.Empezando así la segunda carrera

    armamentística, entre la oruga y el depredador.

    La segunda estrategia se basa en el uso de veneno y colores

    brillantes como advertencia para defenderse, obteniendo a Foto 2. Oruga de Hemeroplanes triptolemus (Costa Rica)

    menudo las toxinas de la planta huésped. Para no morir de hambre, los depredadores mejoran

    la manera de hacer frente a los venenos y, a su vez, las orugas son cada vez más venenosas.

    Esta guerra química es un laboratorio natural al que, desafortunadamente, se le dedica poca

    investigación.

    Cuando la oruga ha conseguido alimentarse lo suficiente y sobrevivir al ataque de

    depredadores, busca un lugar protegido donde transformarse en pupa. En este estado no se

    alimenta, simplemente sufre grandes cambios metabólicos y morfológicos que darán lugar a

    la mariposa adulta, la misma que le deleitará con su presencia durante sus días en el

    Explorer’s Inn. Pero recuerde, antes de convertirse en vistosos insectos alados, la mariposa de

    su foto ha pasado por otra vida…

    RNs PARA LA CONSERVACIÓN DEL LOBO DE

    RIO

    RNs DE EXPLORER’S INN CON

    EL 1º CENSO SIMULTANEO DE

    LOBO DE RIO (PTERONURA

    BRASILIENSIS) EN LA RESERVA

    NACIONAL DE TAMBOPATA

    (por RN Pablo Toledo)

    Foto 1. Kurt, lobo de rio de la laguna de Cocococha.

    Como la mayoría de los lectores sabréis el lobo de rio (Pteronura Brasiliensis) es una de las especies de mamíferos más emblemáticas, y también amenazadas, de la

    Provincia de Madre de Dios y del Perú.

    Nuestro protagonista es un mamífero acuático de la familia de los mustélidos que

    puede alcanzar hasta los 2 metros de longitud, siendo así la especie de nutria más

    grande del mundo. Es también la más social de las nutrias, pues se la puede encontrar

    en grupos familiares de hasta 15 o 16 individuos cuya base estructural consiste en una

    pareja monógama y territorial acompañada de sus crías de años anteriores. El lobo de

    rio se distribuye en las Cuencas del Orinoco y el Amazonas donde ocupa ríos y lagos.

    Según recientes estudios no existen diferencias genéticas a nivel subespecífico entre

    sus poblaciones, tan distantes entre sí.

    Es necesario mencionar a los lectores de este News Letter que en el pasado esta

    especie fue despiadadamente perseguida por su fabuloso y tupido pelaje, causando

    una dramática disminución de sus poblaciones. Tras cerca de 40 años de comercio

    legal e ilegal de su piel la nutria gigante entró en CITES (Convenio sobre Comercio

    Internacional de Especies Amenazadas) justo antes de su total extinción en 1972.

    Treinta años después, aunque algo

    recuperadas sus poblaciones, los lobos de rio

    se enfrentan a otra serie de serias amenazas

    presentes en toda su área de distribución,

    como son la deforestación, la colonización de

    las riberas por parte del hombre, la

    sobrepesca, la minería, la contaminación y el

    turismo no sostenible.

    Es también de destacar que el lobo de río es una especie altamente sensible a las

    perturbaciones pues tiene preferencia por hábitats que por desgracia son muy escasos,

    como son las grandes cochas de aguas más o menos claras donde se la puede

    encontrar en números relativamente abundantes. Esto, sumado a sus hábitos diurnos y

    a su comportamiento social, permite que pueda ser observada fácilmente en la

    amazonía si se sabe dónde buscarlas. Sin embargo, ¿sabíais que se estima que los

    jaguares son hasta 5 veces más abundantes que las nutrias gigantes?

    Debido a su escaso número y a las graves amenazas a las que se enfrenta, según la

    UICN (Unión Internacional para la Conservación de la Naturaleza) esta especie se

    encuentra actualmente en peligro crítico de conservación. En el Perú, la población

    más grande se encuentra en el departamento de Madre de Dios, concentrada en solo

    24 grupos familiares que suman aproximadamente entre 120 y 180 individuos.

    Una vez aportados estos pocos datos sobre nuestras queridas nutrias gigantes os

    relatamos a continuación los pormenores del “1º Censo Simultaneo de Lobo de Rio

    (Pteronura brasiliensis) en la Reserva Nacional de Tambopata”, llevado a cabo el día

    19 de mayo de 2012.

    Los RN Albert Cámara y Pablo Toledo participaron en dicho censo en el Lago

    Cocococha, colaborando con las investigadoras Lucia Chunga-Lee y Christine

    Mumm, cuyos estudios se centran en bioacústica y etología de esta especie, y por

    supuesto con la inestimable ayuda de Elisban, !personaje sabio y carismático donde

    los haya!

    Foto 3. Imágenes de Elisban, C. Mumm, L. Chunga-Lee, Albert Cámara y Pablo Toledo en Cocococha.

    La metodología del censo básicamente consistió por un lado en la búsqueda, conteo

    y fotoidentificación del mayor número posible de lobos gracias al patrón de dibujo

    único y personalizado que presentan en sus baberos o gargantas, llamados manchas

    gulares (¡como si de huellas dactilares se tratara!), visibles durante sus frecuentes

    periscopeos; y por otro, al recorrido por las orillas del lago buscando y anotando

    cualquier posible indicio de su presencia, como puedan ser huellas, excrementos,

    campamentos y madrigueras.

    El día de censo transcurrió sin incidentes y nuestros lobos se dejaron querer

    prestándose varios de ellos a ser fotografiados; pudimos fotoidentificar claramente

    hasta un total de 4 individuos. Por otra parte, gracias a Elisban, gran conocedor de la

    selva y sus esquivos habitantes, pudimos dar sin problemas con dos madrigueras y

    uno de los campamentos de nuestra familia de nutrias. Aprovechamos para aclararos

    que normalmente cualquier grupo familiar de lobos de rio dispone de varios

  • 10

    campamentos y madrigueras repartidos por su territorio; en los primeros descansan,

    socializan, se alimentan y también defecan para dejar patente su presencia en la zona;

    y en los segundos pasan las noches y dan un refugio seguro a sus cachorros. Y por

    cierto que un servidor puede confirmar de viva experiencia el fortísimo olor que

    desprenden sus campamentos, ¡a decenas de metros de distancia!

    Los resultados del censo en Cocococha arrojaron un número de 9 individuos en

    total, de los que pudimos distinguir al menos un cachorro y un individuo que quizá

    pueda vivir separado del grupo principal (en avistamientos posteriores al censo se han

    llegado a contabilizar hasta 10 individuos en el grupo, con entre 2 y 3 crías). Estos

    números convierten al Lago Cocococha en la cocha con el mayor número de lobos de

    rio del departamento de Madre de Dios, ¡dato que nos llena de satisfacción y orgullo!

    Además, Christina Mumm y Lucia Chunga-Lee han podido fotoidentificar a nuevos

    miembros de nuestra querida familia de mustélidos durante sus largas jornadas de

    estudio en Cocococha, mediante las cuales procuran obtener tanto grabaciones de

    video como de audio utilizando potentes micrófonos e hidrófonos. ¿Y sabíais que las

    primeras grabaciones obtenidas parecen señalar que cada individuo posee su propia

    vocalización, individual y única? Asimismo, también han podido identificar varios

    tipos de vocalizaciones como son las llamadas para agruparse, mendigar comida,

    enfado, etc. Ambas investigadoras aún se encuentran en plena fase de recolección y

    análisis de los datos, pero desde luego las primeras impresiones sobre su estudio ¡son

    excelentes!

    Los resultados de dicho censo pudieron ser presentados durante el “Primer Congreso

    Regional de Investigación y Monitoreo Biológico en Aéreas Naturales Protegidas y

    Corredores de Conservación”, celebrado los días 24 y 25 de mayo en Puerto

    Maldonado, al que acudimos

    todo el equipo de RNs (Foto 4).

    Por otro lado, Christina Mumm

    fue invitada al congreso para

    presentar los resultados

    preliminares de sus

    investigaciones en una

    interesantísima conferencia cuyo

    título fue “Comunicación

    Acústica de los Lobos de Rio

    (Pteronura brasiliensis) como

    Herramienta de Conservación

    Natural”. Foto 4. Investigadoras y RNs en el Primer Congreso Regional de Investigación y Monitoreo Biológico en Áreas Naturales Protegidas y Corredores de Conservación.

    Para terminar os presentaremos a continuación a los 6 miembros fotoidentificados

    hasta la fecha de nuestra familia de lobos de Cocococha ¡Grabad bien en vuestra

    memoria sus características manchas y sus nombres! ¿Seréis capaces de reconocerlos

    cuando visitéis su fantástica cocha? O mejor aún, ¿podréis fotografiar e identificar

    algún nuevo individuo? Si lo consiguierais no dudéis en comunicárselo a cualquiera

    de los RNs de Explorer’s Inn ¡El nuevo miembro que consigáis identificar será

    bautizado con vuestro nombre! ¿Se os ocurre un reto más emocionante?

    ¡Y aquí están los verdaderos protagonistas de esta historia!

    The little Soldier of the Jungle: the Bullet Ant

    (by RN Luis Manuel Díaz Cabello)

    The bullet ant (Paraponera clavata) lives in humid rainforests through the Amazon River

    basin and in Central and South America. It is very easily spotted in the rainforest because of

    its unusually large size (up to 2.5 mm). These ants are famous for their extremely painful

    sting. In fact I would like to speak about this incredible ant, since I had an unfortunate

    encounter with this animal on my first week in the jungle: I suffered his terrible sting in my

    hand.

    Their sting is the most painful of all ants,

    bees and wasps, and, as you may have

    guessed, their common name suggests the

    sting is as painful as being shot by a

    bullet! The ant is also known as the “bala”

    ant or 24-hour ant (”hormiga veinticuatro”

    in Venezuela), suggesting that the pain

    lasts for this long!

    The reason is because this ant is mainly a

    predator, feeding on other insects but also

    on nectar and plant parts.

    Bullet ants attack preys biting hard and attaching themselves using their jaws, then twisting

    their bodies to sting the victim. The sting is also used as a defense, as some unlucky hikers

    including myself have experienced! The bullet ants venom is a neurotoxin, which blocks the

    prey`s central nervous system transmission.

    To humans the sting is usually very painful, intense pain lasting 3-5 hours and lessening over

    the next day. In the Amazon region, bullet ants have been used in traditional ceremonies,

    especially when a boy enters manhood. These painful bites have also been used medically to

    treat rheumatism.

    In my case I was 12 hours suffering the terrible painful because I was bit by a medium size

    bullet ant. I never thought that one small ant could produce this incredible pain.

    A bullet ant nest is usually built at the base of large trees, and a colony consists in a few

    thousands individuals. However, when away from the nest, the ants are nearly seen alone,

    climbing on trees as far as the upper canopy, looking for suitable preys.

    They are both arboreal and terrestrial but are most often spotted climbing up a tree trunk or on

    low branches. The ants are mainly active at night but are also seen during the day. Workers

    are 18-25 mm length and their bodies resemble that of a wasp more than an ant.

    One helpful advice would be that there may only be one more thing you want to know about

    the bullet ants: how to avoid them. This will be very easy if you follow the general rules for

    visitors to the jungle: PLEASE!!! Do not touch any trees or plants in the forest, at least not

    before looking first and you will avoid their unbearable pain.

    The Resident Naturalist Program at Explorer's

    Inn

    Since the early 80’s, the Explorer’s Inn has offered young and older graduates in natural sciences the opportunity to stay an extended period of time in the rainforest, in order to

    conduct research. In exchange for their upkeep, the Resident Naturalists (RNs) provide lodge

    visitors with information about the rainforest and the research undertaken. The RNs also help

    resident guides improve their knowledge on natural history and foreign languages. In the 80s

    and 90s, the RNs used to guide tourists, especially during the high season, but later the

    Peruvian Safaris decided to employ only Peruvian guides, in a good eco-tourism tradition.

    RNs in a congress in Puerto Maldonado

    Pablo Toledo Monsonis, Spain (May - October 2012)

    Pablo is a biology graduate who has coursed a Master’s degree on Management and Healthy

    of Wildlife in the University of Murcia, Spain. Moreover Pablo is qualified as Technician on

    Zoo Parks and Aquariums. He is from Canary Island, Spain. Currently, he is the manager of

    the Spanish ONG “Carthago, Asociacion de Estudios y Conservacion de Naturaleza” .On the

    other hand, he collaborates with the Toxicology Departament of the Veterinarian Faculty of

    Murcia University on the research of heavy metals and organochlorine levels in cetaceans and

    marine birds. He left all his work in Spain to come to the National Reserve of Tambopata as

    RN in Explorer’s Inn lodge. He really loves the jungle and all his wildlife and he hopes to

    work in something related with tropical biodiversity as soon as possible.

    Luis M. Diaz Cabello (April - October 2012) He studied Biology Degree in the University of Extremadura 2009 (Spain) and Msc in

    Biology and Biodiversity Conservation in the University of Salamanca (Spain) 2011. One of

    his dreams of his childhood now is fulfilled being in the jungle of Rainforest. As a biologist,

    he needs to spend some time to discover the wonders of the jungle. In his opinion, taking part

    of the RN program is a great opportunity for him to travel, to work in the nature and to gain

    refined knowledge about the Neotropics. He is enjoying his time at EI thoroughly, and he is

    Albert Camara Balestegui (May - October 2012)

    Albert is a Biologist who cursed his degree in the University of Barcelona. He has also cursed

    a Master’s degree on Biodiversity Management in Mediterranean Environments in the

    University of Murcia (also in Spain). He has been working mainly with marine mammals in

    Azores Islands (Portugal) and in Spain, but he has been also volunteering with sea turtles and

    monkeys. He actually likes animals in general, with special attention to mammals. He always

    wanted to come over to the jungle to experience the feeling of living into the wild. His most

    precious dream is to spot some of the big cats existing in the rainforest, specially the majestic

    jaguar. In fact, Albert has started his own personal project in Explorer’s Inn: he is trying to

    monitor the presence of big cats around the lodge.
