The nests are multifunctional structures built by mammals, birds, reptiles, fish and insects. Its design and location depend on the genus of the species, however, the main function is the same: create an adequate environment for eggs and hatchlings, when they are born.
Female oriole (Icterus sp.) is the one that builds the nest.

Characteristics
Tapirus bairdii Gill. It is the only tapir that lives in Central America, except in El Salvador. It can weigh up to 300kg and measure 2.60m long. Their fur is dark brown on top and paler on the bottom, with white stripes around their ears and lips. They are herbivores and it is known that they consume the following species:
Here are photographs of colonies of ant nests in the treetops overlooking the Rio Polochic. This river flows from Alta Verapaz to Izabal and enters Lake Izabal.
We did not have 400mm, 600mm, or 800mm lenses on this field trip of several years ago. Now we have found comparable arboreal ant nest colonies in the IDAEH camp area of Parque Nacional Yaxha Nakum Naranjo. We will present the Yaxha nests in a future FLAAR Mesoamerica report.
The king vulture is one of my favorite birds, due to its colorful head and its rarity: I have never seen one in the wild until this February.
One of the park rangers, Teco (Moises Daniel Perez Diaz) has pointed out king vultures circling in the air above the park on several earlier trips (we go to the park once a month, every month). But usually the bird was so high in the sky and so far away that even with an 800mm prime telephoto lens I did not even attempt to capture it.
But in late February the bird was a tad less far away, but focusing on a soaring vulture is tough when you are in a lancha which is swinging from side to side from the waves (even calm Lake Yaxha has wind-blown surface movement).

So here we show the first attempts to document this rare vulture. If you wish to see this bird, Sarcoramphus papa, connsider visiting Parque Nacional Yaxha Nakum Naranjo, Peten, Guatemala. This park is a great place for birders, especially if you like water birds, especially shore birds. Hotel Ecolodge El Sombrero is available at entrance to the park.
To get better photos you need to be on land, not in a boat; need a tripod with gimbal, and a 1000mm lens or a digiscope. We do not yet have a digiscope. If you are able to support advancing our project capabilities at Yaxha (by providing a Nikon, Leica, Zeiss or Swarovski digiscope for our Nikon or Canon cameras, donations are appreciated. Donations to FLAAR are tax deductible for US citizens: frontdesk symbol FLAAR.org is our contact. We assume you can join these words with the appropriate symbol to create an e-mail address.
Other equipment we need is any good model Sony mirrorless camera (a7R III or a9) and their special Sony FE 400mm f2.8 GM OSS lens. This would be really appreciated to photograph spider monkeys, howler monkeys, or raptors high in the trees. The Nikon lens, AF-S NIKKOR 500mm f/4E FL ED VR, is another item that could help our entire team of photographers and researchers of plants, mammals, birds, pollinators, and other aspects of Neotropical flora and fauna of the Mayan areas of Central America.
You can also join our team on our next visit to Parque Nacional Yaxha Nakum Naranjo. We go every month, though most of our days are studying insect nests in trees, searching for 3-dimensional lichen, and documenting previously undocumented rain forest ecosystems (every kilometer there is a totally different ecosystem: some are 90% palm trees, some are 90% other trees with almost zero palm trees: we even found a pristine grassland savanna last field trip, the first time an untouched savanna has been photographed and documented for this area of Guatemala.
Reportedly there are 80 crocodiles in Laguna Yaxha (not sure whether that includes count for Laguna Sacnab). We can now substantiate presence of crocodiles in Rio Holmul, a short walk from the impressive ruins of Nakum.

To reach the water areas of this river be sure you have a guide; and realize that hungry crocodiles can jump out of the water with lightning speed to grab a meal of fresh meat.

As a child growing up in the Missouri Ozarks, me and my brothers and sister had fun finding all the giant engorged ticks on the family dog. We would put the ticks on the floor and stamp down hard with our shoe to see which of us could squirt blood the furthest.
Thus it was great, 70 years later (I am 74 years old now), to find the same large blood-filled ticks, this time on a Bufo species (a toad with venomous sacs).
Juan Pablo took these photos since I was in another part of Peten that day.
Fortunately no tick has survived on my legs or arms long enough to get very large. But frankly I did not know that ticks would focus on a toad: I thought they would prefer monkeys or jaguars. So today I have learned another fact about biodiversity in the Neotropical seasonally dry rain forests of Guatemala, Central America.
There are at least two species of genus Bufo in Peten: Bufo valliceps and Bufo marinus. I estimate this is Bufo valliceps.

Yes, several species of ants of the Mayan areas of Guatemala make their nests in trees. Of course endless Mesoamerican area species also make nests underground. But we have found two kinds of arboreal ant nests at Parque Nacional Yaxha Nakum Naranjo:
Light-colored, using leaves to hold nest onto the branches
Dark brown, almost black, ant nests hanging from limbs
In both cases you often get a “colony”: we have found three to six leaf-pendant arboreal ant nests within a few meters of each other (on different trees). Last week at Parque Nacional Yaxha Nakum Naranjo we found over 40 dark nests on about four different trees which were near each other. These dark nests were often more than 6 per individual tree. I have seen even more along the Rio Polochic, Izabal, Guatemala: dozens or even scores of nests in adjacent trees, high above the ground.
We also occasionally find nests of both species within 3 to 4 meters of the ground when the limbs are leaning over the shore of Lake Yaxha.
As soon as funding is available we will publish all the high-resolution photos of each and every nest, but now we at least want to get this NEWS item posted.
