In commemoration of National Quetzal Day in Guatemala, we encourage you to learn about the national bird of this country, but in a different way. Here you will find an extract from The bird-snake mansion, one of the most beloved literary works in Guatemala, written by Guatemalan author Virgilio Rodríguez Macal. In correlation with different paragraphs of the extract, you will also find scientific data related to real-life elements described by Rodríguez in his tale.
Habitat and distribution
Now, another inhabitant of the rooms of Jorón, the cold,
was Gug, the Resplendent Quetzal…truly, he was the most beautiful of all, the most
beautiful among all those who move
around
the vast extensions of the Green World…

Pharomachrus mocinno, also known as the Resplendent Quetzal, is truly a beautiful bird endemic to Mesoamerica. Its most usual habitats are patches of high-elevation tropical, rainforests and cloud forests in the geographical region that ranges from Chiapas, in Southern México, throughout Central America, and Panama (Renner, 2005). This magnificent bird is usually found at elevations exceeding 1,400 masl, often in very humid forests with abundant broad-leaved oaks (from the Quercus genus), pines (Pinus spp.), and other evergreen tree species (Kappelle, 2006). Studies have found that P. mocinno prefers to inhabit primary forests (forests that have been not disturbed by human activity), and that it is also able to survive and reproduce in some secondary forests (forests that develop after having cleared the original primary forest) (Chokkaingam, 2001; Renner, 2005).
Characteristics
He was known by the name Gug, the snake-bird, since he truly looked like a cute little bird who was always followed by two or more snakes of the most beautiful colors… Gug’s chest was red as blood, with a little white. His body had an unidentifiable color, between blue, gold, and green, as if the rainbow itself lived on him forever, broken into a thousand pieces.
Divine, most truly, was the bird-snake, since these snakes that followed him were no other than Gug’s tail, a tail with three or even more of the longest feathers, that looked each as a thin rainbow…
When Gug moved around the ground, the leaves, and ferns shook behind his body, as the feathers of its tail went through. True divine snakes are what the feathers of its tail looked like, which followed him submissively as if they were snakes of Heaven, with no poison, and with no evil.

Although the Resplendent Quetzal is famous for what its name describes, a sumptuous bird of iridescent emerald colors, this description doesn’t fit all the members of the species. As can be observed in many instances in nature, P. mocinno presents an evident sexual dimorphism in adults, a condition where males and females from the same species have different appearances (Britannica, 2024; Dayer, 2020). Adult males have long and green uppertail covert feathers that grow beyond the tail, as well as small feathers on the head that form a crest, and bright yellow beaks. This, along with the iridescent gold and green feathers that cover most of its body and the bright red feathers of its belly and undertail covert, are the most distinctive features of a male Quetzal.
The female’s appearance is a bit less eye-catching; the feathers on its belly, throat and sides are grayish brown and their beaks are dark gray. Females also have a crest and uppertail coverts, but these are much smaller and less developed than in males. Nevertheless, females have the same beautiful golden-green feathers on body areas like the crown, back, wings and uppertail coverts (although they do not grow beyond the tip of its tail) (Dayer, 2020).

One of the most diverse and fascinating groups of reptiles are lizards, which occupy a fundamental position in the ecosystems of the entire planet. These extraordinary creatures can have a wide variety of shapes, sizes and behaviors, which not only reinforces the importance of studying them, but also makes them very interesting.

Lizards constitute a group of four-limbed organisms with scales, an external ear opening, and movable eyelids (Almaraz, 2024).
In Guatemala, there are around 106 species, divided into 17 families among which are chameleons, skinks, iguanas, and geckos. The families are: Anguidae, Corytophanidae, Dactyloidae, Eublepharidae, Gekkonidae, Gymnophtalmidae, Helodermatidae, Iguanidae, Mabuyidae, Phrynosomatidae, Phyllodactylidae, Scincidae, Sphaerodactylidae, Sphenomorphidae, Teiidae, Xantusiidae, and Xenosauridae.

Given their great diversity in the region, it is not a surprise that these animals were portrayed by the Maya in the past, and that they made their way into some more modern Maya cultural expressions. How? Take a look at the following examples:
To begin with, some of the rulers in the Maya civilization were named after lizard species. In Chiapas (Mexico) there was at least one ruler named Aj Sak Teles, which means the White Lizard (Davletshin, 2009; Houston et al., 2017). Not far away, was registered a second name including the name of a lizard, and curiously, a color as well. The name is Aj Yax Tolook, which means the Green and Blue Lizard, and it was found on a polychrome cylindrical vessel from the Lord of Petén (Houston et al., 2017). It is speculated that this name in particular may be referring to a species of basilisk, which in addition is believed to have been used for medicine by mashing its brain (Houston et al., 2017).
Most of the ideas discussed in this article regarding the different meanings that snakes hold in the Maya art where taken from Saturno et al. (2005) Los murales de San Bartolo, El Petén, Guatemala, parte 1: El mural del norte.
Snakes are definitely present and relevant in the cosmovision of many different cultures. For instance, in western culture snakes are linked with the devil, as well as with deception and temptation, attributes that derived from Christianity. The Mayan culture was no exception and had its own way of depicting and understanding snakes. They used them frequently as symbols that held different meanings. Due to the fact that today, 16 of July, is World Snake Day, we want to share how Mayas represented snakes in their art.

Snakes are found in many different artifacts, sculptures and ruins from Pre Columbian cultures. They are portrayed in Stela 4 of Takalik Abaj; Structure 5d-33-2º from Tikal; vessels from different cities including Naranjo and Kaminal Juyú; sculptures in staircases from Teotihuacán, Xochicalco, and Chichén Itzá, and many more (Saturno et al. 2005). They were even captured through architecture, such as with the optical effect of the descending serpent in the pyramid of Kukulán, in Chichén Itzá, which happens on every spring equinox.
Regarding their cultural relevance it is evident that the Mayas thought of snakes as symbolic animals since one of the most powerful dynasties is now known as the Kaanul or Snake Head Dynasty (or just Snake Dynasty). This dynasty is thought to be among the only ones that got to build the closest thing to an empire (Taub 2024). Their kings and elite were depicted with an emblem that shows up across the Mayan region called the grinning snake (Vance 2016).

Turning back to snake actual representations, some of the most detailed snakes in Maya art can be found in the Murals of San Bartolo. There are at least 4 of these animals in these murals and two of them are very close in appearance to real species that inhabit the Maya jungle. According to Rodríguez (personal communication, July 10, 2024) one of this species could be Bothrops asper due to the triangular pattern that adorns one of the drawings. Other local species, such as Crotalus spp. and Boa constrictor also have a triangular pattern however.

Human well-being depends directly or indirectly on the services provided by ecosystems. Amphibians represent a high proportion of global species diversity and include species widely distributed around the world that perform a variety of functions that benefit humans. They keep insect pest populations in check, help control algal blooms in the water, and facilitate decomposition and nutrient cycling through waste excretion, improving soil quality by digging burrows, and are also an important food source for several types of organisms, including animals such as mammals, birds, fish, reptiles and even other amphibians. In addition to all the natural factors, amphibians have helped advance medicine and science by being studied as model organisms.

They have an important ecological and economic role within ecosystems. They are essential in the food chain, both in water and on land. Without them, the chances of our ecosystems collapsing are high. Amphibians are considered accurate indicators of environmental health and habitat quality due to their high vulnerability to pollution and environmental changes, which is why they are considered “bioindicators.” Simply put, if you see a frog or salamander, you'll probably think the environment is healthy. This good environmental quality is important not only for amphibians, but for all nature and biodiversity, including humans. In Neotropical ecosystems they play a key role in energy flow and nutrient cycling in both aquatic and terrestrial environments.
One noticeable feature of the new MUNAE exhibits of Director/Administrator Christopher Martínez is the biodiversity of the fauna presented by the artifacts that he selected to be featured in the new exhibits. So far I have found over a dozen animals and one conch shell. There are also several scenes with flowers but the present web page is on the animals of the newly featured ceramics and stone sculptures that you can see and experience when you come to visit MUNAE, near the airport in Zona 13.

Spider monkeys (Howler monkey almost never pictured)
Maya dog (no fur on most of body, no barking sound)
Armadillo (on ballgame hacha)
Deer (3D ceramic figurine)
Jaguars (Quiche Urns; plate showing human sacrifice from Uaxactun; Tikal stela)
Puma (no spots so I suggest it is a cougar)
Snake (on ballgame hacha)
Parrots (3-dimensional ceramics)
Macaw (3-dimensional ceramic)
Vulture (3-dimensional ceramic)
Bufo toad (large stone sculpture, Rhinella marina, previously Bufo marinas)
Bat (on Chama polychrome vase)
Fish (on Kaminaljuyu stone panel)
Conch shell (on polychrome plate with gorgeous flower above)
Two easy to see jaguars leap down to grab the bleeding body of a sacrificed victim. There are several vases and plates that show trained jaguars assisting in human sacrifice ceremonies; this plate from Uaxactun is one. There are also two black spider monkeys in the upper left. Their role in this scene needs to be researched. The bottom ring of the plate has jaguar pelage spot designs.
To provide documentation for school children, it would help to have a book for their age to describe each animal in the MUNAE collection. We have many years experience preparing (MayanToons) books and animated videos for school children.
Plus for the general public who are visiting the museum, and for archaeologists and iconographers, it would be great to have a book that introduces the iconography of each mammal, each bird, each reptile and the conch shell. FLAAR has the experience.

Who are the Abronia Lizards?
One of the most fascinating reptiles in the Mesoamerican region are the lizards of the genus Abronia, representing one of the most notable endemic reptiles in the area. These remarkable animals belong to the family “Anguidae”, and some studies suggest their inclusion in the taxonomic group “Toxicofera”, which also includes “helodermatids” (Helodermatidae), “iguanas” (Iguania), and “monitor lizards” (Varanoidea). Their main distribution spans in Mexico and Central America, with Guatemala being a significant distribution point. Approximately 28 to 30 species of these lizards have been identified within this genus, with 12 found in Guatemala alone, at least 8 of which are endemic to the region. Endemic species in this area include A. anzuetoi, A. aurita, A. campbelli, A. fimbriata, A. frosti, A. gaiophantasma, A. meledona, and A. vasconselosii. It is essential to consider that taxonomy, classification, and the number of recorded species may change as more comprehensive research is conducted and new populations are identified.
