A few days ago our reserve manager, herpetologist Juan Pablo Reyes, was working with community members in our Naturetrek/Viscaya Reserve a few kilometers north of the town of Banos (Tungurahua province) when he accidentally encountered a lizard he had never seen before. It proved to be Riama meleagris, a species that has  previously been recorded from only two other sites, both in Tungurahua province. Both those other localities are now now highly disturbed, and the species is classified as Near Threatened by the IUCN. Our reserve is the only protected area where this species has been found; it is good to know that it will be protected from deforestation here at least.

Different species of insects are primarily distinguished by their male genitalia. We found both a female (with sword-shaped ovipositor) and a male individual of this species. I include the genitalia here in case there is some expert who can help decide whether this is a new species. It is similar to Moncheca elegans but the colors are not right. Photo: Lou Jost/EcoMinga

My friends Tom Walla and Johanna Varner, professors at Colorado Mesa University, came to visit our Rio Zunac and Cerro Candelaria Reserves last month. They set up a light to attract night insects. They were especially interested in moths, and I’ll write more about that later. But along with many amazing moths we attracted two feisty individuals of this spectacular katydid. They were very active and often did a raised-wing display to try to scare me. They also really enjoyed biting me with their giant bright yellow mandibles. I became fascinated by them. They stayed alive for two weeks, allowing me to observe and photograph them (I found that they like to eat flowers), and when they died I mounted them and photographed them even more.

They belong to the genus Moncheca, which contains some of the world’s fanciest katydids, like M. pretiosa. Our individuals are most like M. elegans, but the colors don’t match an expert-certified photo on the internet. The male genitalia are the definitive way to tell them apart, so I provide a photo of the genitalia above in case an expert looks at this post. This exact form has been seen and photographed by my friend Andreas Kay, and also by someone named Moira who submitted her picture of it (from Sumaco, in eastern Ecuador, not far from our reserve) to an internet bug ID site, to no avail.

Yesterday I wrote about the exciting discovery of the Choco Vireo in our Manduriacu Reserve. Now I want to add a few of the other special birds that have recently been found there by our staff member José María Loaiza Bosmediano and others.  Certainly the most beautiful find is the Orange-breasted Fruiteater (Pipreola jucunda),  a Choco endemic found from 600m to 1900m on the western slope of the northern Andes. Though it has a narrow range, it is not yet endangered.

Another special Choco endemic found in Manduriacu Reserve during the last Christmas Bird Count was the Long-wattled Umbrellabird (Cephalopterus penduliger). This relative of the Andean Cock-of-the-Rock (the bird on our banner at the top of this page) is one of Ecuador’s strangest birds. The males gather at leks to display from special perches to attract females, making a weird display and a low mooing sound.

Here are a few random YouTube videos of the bird’s display:

This is one of three species of Umbrellabird in the world.  Another species, the Amazonian Umbrellabird (Cephalopterus ornatus), lives in our Rio Anzu Reserve, while the third species, the Bare-necked Umbrellabird (Cephalopterus glabricollis), lives in Costa Rica and Panama.

Another fancy bird found during the Christmas bird count in the Manduriacu Reserve was the Choco Trogon (Trogon comptus), also called the Blue-tailed Trogon though that name is also applied to an Old World species.

The quetzals are fancier relatives of the trogons. The Crested Quetzal (Pharomachrus antisianus) seen with the Orange-breasted Fruiteater in the picture at the head of this post, is one of the most beautiful of Ecuador’s birds, though it lacks the long tail of the Resplendant Quetzal of Central America. It occurs on both sides of the Andes; here is a photo by Roger Ahlman taken on the eastern slope of Ecuador at San Isidro Lodge:

Manduriacu also has the Golden-headed Quetzal, Pharomachrus auriceps:

There are several toucan species at Manduriacu; one of my favorites is the Crimson-rumped Toucanet (Aulacorhynchus haematopygus):

The Purple Quail-Dove, Geotrygon purpurata, below, is another of the special Choco endemics of Manduriacu.  This species, like the Choco Vireo discussed yesterday, is classified as Endangered by the IUCN Red List criteria. It is found only between 600m and 1100m, a range of elevations which is also one of the most heavily exploited by local people for logging and agriculture. The world population of this species is estimated to be only 600-1700 adults, making it more endangered than even the Choco Vireo, and probably more endangered than any other bird found in any of EcoMinga’s reserves. Jose Maria is monitoring a nest with a camera trap (photo below), so we might learn more about the biology of this rare species.

Jose Maria included this note about the discovery of the nest photographed above:

“El  17 de noviembre, encontramos junto con Alejandro Naranjo  y Galo Pantoja (ex y actual guardaparque respectivamente), un nido activo de Geotrygon purpurata Purple Quial-Dove y/o Indigo-crowned Quail-Dove.

Increíblemente el nido está a tan sólo unos ocho metros del sendero que conduce a nuestra casa-refugio. Ésta es una especie de alto interés conservacionista pues es endémica de la región biogeográfica del Chocó y se encuentra amenazada de extinción en la categoría EN PELIGRO (EN) a nivel global. Aparentemente se trataría del primer encuentro del nido de está palomita; sin embargo estamos buscando información relacionada para corroborar éste dato. Por lo pronto hemos colocado una cámara trampa para monitorear todo el desarrollo y estamos muy ansiosos por saber lo que ocurrirá, esperamos también que los depredadores ¡no lo encuentren!

Nos hemos percatado que sólo hay un huevo de color blanco y al parecer será el único de la nidada. La estructura del nido es sencilla como se puede ver en la foto y está a un metro de altura desde el suelo.

La especie es mayormente terrestre y propia del interior de bosques muy húmedos y lluviosos en buen estado de conservación. …en Manduricu, el nido está casi en su límite máximo de distribución altitudinal (1100msnm).

Pronto tendremos más noticias al respecto y esperamos obtener buen material fotográfico y videos.”

Here is a YouTube video of the bird from “Un Poco del Choco”, a cloud forest reserve near San Miguel de los Bancos in Pichincha province, Ecuador:

The Purple Quail-Dove is closely related to the very similar Sapphire Quail-Dove of the eastern lowlands of Ecuador, on the other side of the Andes. The two species are believed to have split from each other about 1.2 million years ago; there are slight differences in song, plumage, and habitat (the Purple Quail-Dove is found only in foothills while the Sapphire Quail-Dove is found only in lowland forest, at least in Ecuador). They had been lumped into a single species after initially being described as separate species; the recent decision to re-separate them is based on the discussion presented here.

The full list of birds seen to date in Manduriacu is available online here.

Many thanks to Jose Maria, Edison, and Galo for the great work they have been doing in Manduriacu!

All of these birds, with the possible exception of the Purple Quail-Dove, should also be found in our Dracula Reserve.

Endangered Choco Vireo discovered at our Manduriacu Reserve

The Choco Vireo (Vireo masteri)  is one of the rarest and most local of the bird species endemic to the Choco bioregion of western Colombia and northwest Ecuador. It was not discovered until 1991, when Paul Salaman (now CEO of Rainforest Trust, one of EcoMinga’s major funding partners) spotted and mist-netted it in a cloud forest in western Colombia. It was officially described and published in 1996 by Salaman and Gary Stiles, a pioneering Latin American ornithologist who has worked extensively in Costa Rica and Colombia. Tjhe vireo was later found in nearby northwestern Ecuador (Esmeraldas province) by Olaf Jahn, Byron Palacios, and Patricio Mena Valenzuela, and in 2010 another population was found in Ecuador’s Pichincha province by Dušan Brinkhuizen and Alejandro Solano-Ugalde. Like the Black Solitaire and a few other species, it appears to be found only in the wettest cloud forests in a narrow band of elevations (1100-1600m) in a badly deforested and fragmented landscape. It is classified as EN (Endangered) in the IUCN Red List.

EcoMinga’s community relations specialist and noted ornithologist José María Loaiza Bosmediano (whose position exists thanks to a generous donation by Felipe Villamizar) recently organized a Christmas bird count in our Manduriacu Reserve in Imbabura province in western Ecuador. In the course of this event, he and his companions Edison Ocaña (Aves Quito) and Galo Pantoja (our reserve guard) discovered and filmed two individuals of the Choco Vireo in this reserve, the first record for Imbabura province! They also made still photos and recorded its call.

The Manduriacu Reserve was begun by Sebastian Kohn, who recently gave his properties (about 400ha) to EcoMinga to manage. Our management is partly funded by the government’s SocioBosque program, which pays private individuals (but not foundations) to conserve their forest; Sebastian has enrolled his properties in this program and gives us all the money he receives from it.  When the program ends we will be given full title to the properties. One of the vireo sightings was in one of these properties.

Last year EcoMinga began a joint project with the IUCN-Netherlands under their “Small Grants for the Protection of Nature” program, sponsored by the Dutch National Postcode Lottery,  to purchase an additional 132ha to fill a strategic gap between our present Manduriacu properties. The vireo surely occupies this property as well. In addition the Centro de Rescate Ilitío and the Fundación Cóndor Andino have financed EcoMinga’s purchase of a neighboring lot where the second vireo was sighted. We hope to eventually grow this reserve to cover 1000ha.

The vireo sightings in this area are important because there are very few Ecuadorian records of the species in protected areas (though it should also be present in our Dracula Reserve in Carchi province). This discovery increases the odds that the species might be able to survive in the country in spite of the ongoing deforestation at these elevations.

Family visit

Last week two of my brave family members from the US visited some of EcoMinga’s reserves with me.  My sister Lorie Koessl and my brother Brad’s 17-year-old daughter Saige Jost are both nature-lovers and hikers, so they were perfect companions. Here are some of the things we saw in and around our reserves in six days of hiking.

Mammal encounters are rare here. Usually we only see them in our camera trap videos, or we find their tracks or scat. But on our visit to EcoMinga’s Rio Anzu Reserve in the Amazonian foothills, we were sitting on rocks along the river when we heard a strange call,  not quite bird-like….a few seconds later two tayra (Eira barbara) appeared on the opposite bank, jumping from rock to rock. These are relatives of the wolverine and mink, fairly large muscular omnivores that are capable of killing large birds and mid-sized mammals. This was one of the best views I have ever had of them. They were not concerned by our presence. My sister had borrowed one of my cameras for the day and she managed to snap a few pictures of them as they went along.

Of course there were many invertebrates in the Rio Anzu Reserve. Here is a colorful grasshopper photographed by Saige on her cell phone:

In our Rio Zunac Reserve, we encountered a couple of rodents. One especially cute individual had made a nest in an abandoned cabin that used to belong to our park ranger Fausto Recalde before we bought the land from him:

Incredibly, this turned out to be a recently discovered new species of mammal,  Albuja’s Climbing Rat (Rhipidomys albujai), that was only described a few months before our visit, by our friend Jorge Brito and coauthors:

http://www.tandfonline.com/doi/full/10.1080/23766808.2017.1292755

From the Climbing Rat’s cabin Lorie spotted our magnificent pair of Black-and-chestnut Eagles, though they were too far away to photograph. This cabin is just below their former nesting site, but it seems they are not currently nesting there. Perhaps they are still caring for last year’s fledgling.

On a day hike to our Cerro Candelaria and Naturetrek Reserves, we were able to spend time watching the well-named Torrent Duck (Merganetta armata) feeding in a raging whitewater stream that would have quickly killed almost any other bird or mammal.

This is a very distinctive duck appears not to be closely related to the familiar north temperate duck species, but its position in the tree of life is still uncertain.

On the day of the Torrent Duck sighting, our ranger Fausto Recalde brought his 5-year-old daughter Amy along. She was an excellent guide, who found several interesting things that we had not noticed. She was also very playful; she did this controlled falling trick about 20 times in succession, laughing all the while:

Night hikes are always special in the tropics. We took a night hike during our three-day stay in EcoMinga’s Rio Zunac Reserve, and in the space of less than a half hour we saw a non-stop show of fascinating insects, arachnids, frogs, and sleeping lizards:

There were neat invertebrates during the day too along the Rio Zunac. On our return home we saw these:

Some of the invertrebates were less welcome. There was an eruption of biting horseflies in the Zunac Reserve that week, and here are some that we killed while they bit us during a quick dinner:

Dead horseflies killed as they tried to bite us during dinner. This is about a quarter of the total number we killed during that dinner; most were completely squished….Photo: Lou Jost.

On the same rock wall where we piled the dead horseflies, there was a fascinating construction of waxy tubes made by large black bees:
