Anatomical X-Ray Rendition of SCP-XXXX-A

Item #: SCP-XXXX

Object Class: Keter

Special Containment Procedures:

Instances of SCP-XXXX are to be contained on Site-██, Site-██, and Site-██; within individual cells designed for rest and daily nourishment. The cells are to be connected to an adjacent testing area, separated by cell containment doors and failsafe gates. The cells and testing area must include an array of infrared cameras protected behind impact-resistant glass, and sedative gas pumps for safe SCP interaction and containment.

The testing area consists of a containment zone large enough to allow adult SCP-XXXX ample space and variability to exercise and participate in tests. Structures and vegetation within the testing area are permitted, so long as they prevent SCP-XXXX from scaling higher than the observation cameras and possible containment limits. Two-way observation windows and an intercom system are mandatory for communication and visual interaction with SCP-XXXX.

SCP-XXXX instances are to be tested daily on an individual or cooperative basis. Testing should consist of physical and cognitive exercises to measure intelligence, communication, cooperation, perception, endurance, and additional research as seen fit. Should items or D-Class personnel be introduced into the testing area, all instances of SCP-XXXX must be contained within their cells before the main access door be allowed to open. Due to Incident-XXXX-73, multiple instances of SCP-XXXX are not to maintain contact for more than two weeks at a time for a maximum term of six months. Should all instances of SCP-XXXX within a testing colony be in association with one another by the end of six months, they must be relocated to separate testing colonies and/or sites to maintain disassociation.

SCP-XXXX containment cells and testing areas must be inspected on a monthly basis to repair possible damage to the enclosures, and identify any items or tools which may aid the ability to breach containment. During standard SCP-XXXX relocation, all SCP-XXXX instances will be sedated and bound within their cells for a standard health inspection. Although rare, any instance of SCP-XXXX which exhibits abnormal behavior, injury, or other health complications at any time must be treated by the same procedure.

Adult SCP-XXXX are required to have a sub-dermal tracking chip implanted near the left trapezius muscle or hip, and be fitted with a TESLA collar during transportation and emergency containment procedures. Should a Site experience a containment breach, all instances of SCP-XXXX are to be sedated immediately with security/failsafe doors sealed on lockdown. Should SCP-XXXX breach containment, containment personnel are advised to equip non-lethal countermeasures to subdue and re-contain SCP-XXXX. Currently SCP-XXXX is classified as dispensable under extreme circumstances.

Deceased SCP-XXXX specimens are to be documented and preserved for analysis. Blood samples, tissue samples, and intact organs such as the eyes, brain, and spinal cord are to be extracted for genetic and biological research.


SCP-XXXX is a bipedal avian-like species resembling Troodon fromosus with minor morphometric features akin to Deinonychus antirrhopas. Instances are highly perceptive, agile, and sapient. SCP-XXXXs' origins are currently unknown.

The physical scale of adult-age SCP-XXXX instances average from 1.2-1.5m standing height, 3.5-4m in length, and 82-120kg in weight. SCP-XXXX-A (males) tend to have a smaller physical stature than SCP-XXXX-B (females). The 1:1.125 sex ratio is presumed to be due to separate roles in hunting, territorial management, and raising offspring; similar to modern avian species.

The primary feature of SCP-XXXX is a variety of contour feathers covering most of the body. Long and slender feathers form crests on the head, fledged non-flight wings on the forelimbs, and flaring at the end of the tail. Progressively smaller and lighter feathers are sub-divided with the largest on the back and hips, and the smallest on the underbelly, lower legs, throat, and snout. SCP-XXXX-A possesses elongated crest and tail feathers with uniform coloration patterns for communication and display. SCP-XXXX-B coloration patterns are dull and varied to act as natural camouflage.

The eyes of SCP-XXXX feature a black sclera with a grey reflective iris, and contain enough clarity for 20/6 vision or greater. SCP-XXXX is capable of perceiving differences in ultraviolet and infrared light via spectral tuning (adjusting the sensitivity of long-wavelength vision), possessing greater optical complexity and acuity than most avian species.

While the cranial cavity of the skull resembles that of Troodon, the brain itself differs dramatically from its biological counterpart; possessing a dense arrangement of neurons similar to Corvidae and Psittacus. Extensive intelligence tests conducted on SCP-XXXX reveal that they are capable of recognizing their own likeness, creatively solving complex problems, identifying/formulating abstract concepts, and understanding basic human speech.

SCP-XXXX’s developed nasal cavity and voice box are capable of producing a diverse vocal range for complex communication. Currently, only basic commands have been deciphered. SCP-XXXX has also been observed communicating via body/feather signals and mimicking environmental sounds; including human language. Tests involving extensive communication with SCP-XXXX subjects incited them to respond in a similar human tone. SCP-XXXX occasionally mimics sounds to not only improve its own vocal acuity, but also to test its feedback from the environment and entities which reside within it. Researchers are encouraged to prepare for unanticipated phrases and questions.

SCP-XXXX instances rarely communicate with humans. This is not due to limitations in intellectual or vocal capacity, but rather a lack of association. Despite the dependent nature of containment, SCP-XXXX instances appear to develop an independent mentality from all sentient beings other than themselves. Prolonged exposure to domestication and long-term isolation directly correlates with reduced mental and physical heath.

Instances of SCP-XXXX appear to have instinctive interest to participate in tests which involve physical and cognitive exercise. Learned knowledge and abilities are practiced, applied, and perfected so long as the testing area permits. A majority of tests are designed to exert sufficient strain on the subject to act as a source for maintaining mental and physical health, improve/research potential capabilities, and exhaust the subject to prevent efforts to escape containment.

SCP-XXXXs’ streamlined form, muscle structure, lung capacity, forelimb dexterity, and curved talons aid in their ability to run in excess of 62 kmh, leap approximately 5 meters horizontally (2.5 vertically), swim efficiently, and scale variable, malleable, and near-vertical surfaces. SCP-XXXX’s rigid tail and fledged wings aid in balance and maintaining upright posture while climbing, yet both features remain foldable and flexible enough to maneuver in confined spaces.

SCP-XXXX’s predatory and defensive capabilities come from its extended pedal-digit talons and teeth, primarily used to inflict puncture and laceration wounds. Adult SCP-XXXX may consider humans as viable prey should a smaller or alternate food source not be present. Instances have been observed to actively hunt D-Class personnel when incorporated with physical tests, yet appear to show limited hostility to humans during cognitive tests and communication. This distinction may be due to SCP-XXXX perceiving or prioritizing humans differently when fulfilling instinctual desires (i.e. hunting and learning).

SCP-XXXX’s perceptive and physical capabilities translate to extraordinarily acute reflexes, coordination, agility, and adaptability. As such, SCP-XXXX’s elusive nature and ability to evade capture has hindered The Foundation’s efforts to identify, track, secure, and contain rare instances of SCP-XXXX worldwide. Currently, The Foundation has only identified 663 instances of SCP-XXXX; Approximate population is unknown. Instances of SCP-XXXX appear to be concentrated within the remote regions of Southeast Asia, Indonesia, and Central America.

Should SCP-XXXX exponentially advance in intelligence and proliferate in population growth, there exists the potential for an SK-Class Scenario from a non-technological standpoint. SCP-XXXX could also cause additional K-Class Scenarios by directly or indirectly enabling other SCPs to breach containment.
