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:
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:
On the same rock wall where we piled the dead horseflies, there was a fascinating construction of waxy tubes made by large black bees:
Lorie and Saige, thanks for your visit! It was fun to show you EcoMinga’s reserves!
