A Yellow-eyed Junco (Junco phaeonotus) was both enraged and weirdly fascinated by this rattlesnake, and ignoring our presence completely, this cheeky and rather foolhardy bird kept flying down and landing near the furious, yet fearful rattlesnake. There had been a devastating forest fire in Summerhaven in 2003, and blackened sticks and logs are a common sight there, so at first glance, I had thought that this black snake was just another bit of fire debris, but then the blackness moved and revealed itself as an Arizona Black Rattlesnake. Herpetologists' League. Arizona black rattlesnake, black rattlesnake, black diamond rattlesnake, brown rattlesnake, Cerberus rattlesnake, mountain diamond-back. Found in the United States, in Arizona from the Hualapai Mountains and Cottonwood Cliffs in the northwest of the state, southeast to the Santa Catalina, Rincon, Pinaleno and Blue Mountains. Your email address will not be published. 1500 plates. However, specimens also may be a uniform dark color without any clear dorsal pattern, or the dorsal blotches may be even darker and bordered with white, cream, or yellow transverse rows of scales, or the color pattern may be quite pale with a significant amount of yellow mixed in. Arizona Black Rattlesnakes were initially considered to be a subspecies of the Prairie Rattlesnake (formerly the Western Rattlesnake) and were known as C. viridis cerberus. Like other Pit Vipers (Family Viperidae, Subfamily Crotalinae), Arizona Black Rattlesnakes are venomous and have a broad, wedge-shaped head much wider than their neck, large, erectable fangs that they use to inject venom into their prey or predators, and heat-sensing pit organs in front of their eyes that they use to detect warm-blooded prey like rodents and birds. The pitviper subspecies is mainly diurnal, but in favorable conditions, it can be active at night also. Not seeing any nearby long sticks that we could use, we tried what we discovered to be the completely ineffectual method of rolling a Douglas-fir cone at the rattlesnake in an attempt to get it to crawl away. Article was last reviewed on 13th June 2019. [5] Also often incorrectly referred to as a timber rattlesnake. Until recently, they were then instead considered to be a subspecies of the current Western Rattlesnake and were known as C. oreganus cerberus. Description. [8], Arizona black rattlesnakes undergo morphological color change (gradual change due to changes in number or quality of chromatophores); adults are less patterned than juveniles (also called ontogenetic color change). [9] Some adults can change color relatively quickly (physiological color change: rapid change due to movement of organelles within chromatophores),[9] an ability shared not only with chameleons and other lizards but also with other snakes such as some species in the genus Tropidophis. 511 pp. Near Tucson, Arizona, these snakes can be found in the Santa Catalina and Rincon Mountains, generally from the middle to high elevations.

[5], According to Wright and Wright (1957), adults grow to an average length of 78–109 cm (31–43 in). A postocular stripe is evident in lightly colored specimens, but not so much in darker ones. Unfortunately, I didn't get a photo of the actual strike (it was just too fast), but the rattlesnake did strike a rather menacing pose after that. When on the ground near the rattlesnake, the Yellow-eyed Junco hopped and fluttered about in a strange, nervous, jerky fashion. The Arizona Black Rattlesnake (Crotalus cerberus) is a moderately-large (1219 mm TL) snake that is dark gray, dark olive, or dark brown with 25-46 dark blotches and light interspaces between the blotches.The blotches on the body morph into dark bands on the tail, which fade with age. [6] Hubbs and O'Connor (2012) list an adult size range of 812–1,219 mm (32.0–48.0 in). [7], Sexually mature females bear live young in broods of 4 to 21 neonates.

However, rattlesnakes will not always rattle, and this one certainly did not. Like other pitvipers, the snake makes use of heat sensing pits located on each side of the face to detect prey and predators. Required fields are marked *. [6] The type locality given is "San Francisco Mountains" (Coconino County, Arizona, USA). 870 pp. Like other pitvipers, the snake makes use of heat sensing pits located on each side of the face to detect prey and predators. Crotalus cerberus is a venomous pit viper species[3][4] found in the southwestern United States. Also found at Steeple Rock, in extreme western New Mexico. The Arizona black rattlesnake is the first species of snake observed to exhibit complex social behavior , and like all temperate pit vipers, care for their babies. Arizona black rattlesnake is a poisonous subspecies of snake occurring in the southwestern United States. Not wanting to take any chance of being bitten, we weren't even that close to this unusually irritable and crotchety Arizona Black Rattlesnake, but then we weren't the only ones bothering the poor snake. 2 volumes.

They have darker, saddle-shaped blotches interspersed with yellow to white crossbars along their back and light-colored rattles that contrast strongly with their overall dark coloration. Young have prominent brown blotches and facial markings on a light gray background. Females remain with their young in nests for 7 to 14 days, and mothers have been observed cooperatively parenting their broods. The mechanism for their physiological color change is likely the same as that documented in the closely related prairie rattlesnake (melanin movement within their dermal melanophores),[10] but further research is needed to determine the stimuli for this phenomenon in this rattlesnake.[7]. Near Tucson, Arizona, these snakes can be found in the Santa Catalina and Rincon Mountains, generally from the middle to high elevations. Snake Species of the World: A Taxonomic and Geographic Reference, vol. Arizona black rattlesnake is a poisonous subspecies of snake occurring in the southwestern United States. After it tired of bothering the rattlesnake, the Yellow-eyed Junco perched sullenly on a tree branch above the rattlesnake and kept glaring at it.

Females remain with their young in nests for 7 to 14 days, and mothers have been observed cooperatively parenting their broods.[12]. Klauber (1997) reports the maximum length to be less at 1,032 mm (40 5⁄8 in), with the smallest gravid female measuring 701 mm (27 5⁄8 in). Seeing that the rattlesnake show was over, the Yellow-eyed Junco decided to leave then as well. In July of 2007, we observed this adult Arizona Black Rattlesnake on a dirt road near Summerhaven, Arizona in the Santa Catalina Mountains at about 8200 feet (2500 m) in elevation. Instead of crawling away, the furious Arizona Black Rattlesnake struck the douglas-fir cone fast and hard. [1], It preys upon suitably sized amphibians, reptiles, birds and their eggs, and mammals. Arizona Black Rattlesnakes (Crotalus cerberus) are almost exclusively found in the mountains and upland areas of Arizona, with only a small part of their population range extending into far west-central New Mexico. [7] The Arizona black rattlesnake is the first species of snake observed to exhibit complex social behavior,[11] and like all temperate pit vipers, care for their babies. [7], The color pattern consists of a dark grayish, brownish black, reddish brown, or blackish ground color, overlaid with a dorsal pattern of blotches that are rectangular anteriorly, becoming subhexagonal posteriorly, eventually becoming crossbands just before the tail. The pitviper subspecies is mainly diurnal, but in favorable conditions, it can be active at night also. A few times, the Yellow-eyed Junco even ventured within striking range of the Arizona Black Rattlesnake, but the rattlesnake was too concerned with our nearby presence to risk striking the bothersome bird. Instead it coiled itself up into a tight, defensive coil, puffing itself up and arching its back to make itself look more threatening to us. Campbell JA, Lamar WW.
