Amazon Tree-Boa (Corallus hortulana)
Reptiles of Ecuador | Serpentes | Boidae | Corallus hortulana
English common names: Amazon Tree-Boa, Common Tree Boa, Garden Tree Boa.
Spanish common names: Boa amazónica de jardín, boa arborícola amazónica, boa de los jardines (Ecuador); boa arborícola (Bolivia); boa arborícola del amazonas, macabrel (Colombia); boa arborícola amazónica (Peru).
Recognition: ♂♂ 164.3 cmMaximum distance from the snout to the tip of the tail. ♀♀ 187.6 cmMaximum distance from the snout to the tip of the tail..1,2 The Amazon Tree-Boa (Corallus hortulana) can be identified from most other Amazonian snakes by having a triangular-shaped head wider than the neck, vertical pupils, heat-sensitive pits on the lips, compressed body in lateral view, and a prehensile tail (=capable of grasping).3,4 Corallus hortulana is a polychromatic boa. Dorsally, it presents a variable background coloration (yellow, gray, greenish gray, brown, taupe, pink, orange tan, reddish brown, or black) with a series of dorsoventrally arranged ellipsoid spots, which may be dark brown, yellow, or cream.3–6 These spots are widest in the mid-dorsal region and may be diamond-shaped on the anterior portion of the dorsum.4,5 The venter may present dark spots on a background color that can be white, cream, gray, brown, or reddish brown.2–5 In Ecuador, similar snakes that may be found living alongside C. hortulana are C. batesii, Epicrates cenchria, and Bothrops atrox. Corallus batesii differs from C. hortulana because this species has a green (reddish brown to yellow in juveniles)7 dorsum with enamel-white markings.8 The Rainbow Boa (E. cenchria) has an iridescent orangish dorsum and rounded spots with dark edges that are distinguished from the background color.4 The viper B. atrox can be differentiated from C. hortulana by not having heat-sensitive pits on the lips and by presenting keeled (with longitudinal ridges) dorsal scales.3

Natural history: FrequentRecorded weekly in densities below five individuals per locality..9 Corallus hortulana is an arboreal snake that inhabits old growth to moderately disturbed rainforests, which may be terra-firme or seasonally flooded.2,4,6–12 The species also occurs in human-modified habitats and can even enter human dwellings located near patches of forest.9 Amazon Tree-Boas use vegetation between 0.3 and 25 m above the ground level and are particularly abundant along the margins of rivers and streams.4,6–14 Despite this, individuals can occasionally be found at ground level.4 Corallus hortulana has nocturnal habits, with greater activity during moonless nights and between sunset and midnight, with the majority of this time spent foraging.3,6,13,15 During the day, these boas can be observed coiled with the head hidden among body coils, resting on shaded vegetation, in hollow logs, or in the thatch of roofs.4,9,13,14 Notwithstanding, in Ecuador, an individual was recorded active during the morning (10:00 am) eating a prey,16 and in Brazil one individual was observed at 2:00 pm basking in the sun.17 Also, in Brazil two individuals were observed mating during the day.14
Corallus hortulana uses active foraging as well as sit-and-wait strategies to capture prey, though the latter approach seems to be more common in adults.4,15,18 This snake is euryphagic, which means it consumes a broad array of prey items. Its diet is composed of anurans (mostly treefrogs),19 lizards (anoles, basilisks,4 Iguana iguana, tropic lizards, and whiptails such as Ameiva ameiva),19 birds, and mammals (marsupials, bats, primates, porcupines, and rodents).4,15–20 Likewise, it has been suggested that this snake occasionally consumes fish.21 Ontogenetic changes in diet have been documented for the species, in which juveniles and sub-adults feed on anurans, lizards, birds, and mammals, while adults consume only birds and mammals.18,19,22 There are records of crocodilians (Melanosuchus niger and Paleosuchus trigonatus),15 hawks,9 and owls (Tyto alba)23 preying upon Amazon Tree-Boas. When threatened, individuals of C. hortulana usually make an S-coil and strike.4,17 When manipulated, they can adopt a “protective ball posture,” as well as contract and rotate the body, regurgitate prey, and expel cloacal discharges.3,4,12,15
The reproductive season of Corallus hortulana can vary between locations. There are records of mating in May (in captivity),24 June,14 July,25 and September.14,26 Birth events having been reported from January to June, and in November.27,28 During copulation, the male entangles about 30% of its body around the female and performs movements with its head, including rubbing the chin against the female’s neck and head.26 In captivity, two males copulated for ~37 minutes with a female, without engaging in combat.24 After a gestation period of 6–7 months, females “give birth” (the eggs hatch within the mother) to 2–29 young that measure 28.2–64.4 cm in total length.24,27–29 After birth, females may eat some of their young.29 Under human care, individuals can live up to 15 years.30
Conservation: Least Concern Believed to be safe from extinction given current circumstances..31–33 Corallus hortulana is listed in this category because it is widely distributed, occurs in numerous protected areas, has a relatively large and stable population, and is facing no major immediate extinction threats.31 However, this species can be particularly susceptible to large-scale deforestation, since it requires arboreal vegetation to survive.31 In addition, wild individuals of C. hortulana are marketed as pets, which is why the species is included in Appendix II of CITES.31,34,35
Distribution: Corallus hortulana is native to an estimated 207,837 km2 area throughout the Amazon basin in Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname, and Venezuela.36 In Ecuador, the species has been recorded at elevations between 115 and 495 m (Fig. 2).

Etymology: The generic name Corallus comes from the old French word coral, which was the name given to dangerous savage and barbaric peoples in ancient times.37,38 This term refers to the fierce and perfidious appearance of the species of the genus, among which the anterior teeth of the maxilla and mandible stand out, which are longer than the posterior teeth.38 The specific epithet hortulana is a Latin word meaning “garden”.37 It refers to the variety of colorations that the species presents, reminiscent of a flowerbed.38
See it in the wild: Amazon Tree-Boas can be located with ~15–25% certainty in forest areas throughout their area of distribution in Ecuador. The localities having the greatest number of observations in Ecuador are Río Cuyabeno, Napo Wildlife Center, Sani Lodge, and Yasuní Scientific Station.
