The 1977 Colares UFO Attacks
Brazil’s Night of Fear and the Mysterious Lights Over Pará
In 1977, the small Brazilian island of Colares became the focus of one of the country’s most unusual and unsettling UFO incidents. Locals reported seeing strange lights in the sky and claimed that some encounters led to unexplained injuries, sparking widespread fear among the community. Brazil’s Air Force responded with an official investigation known as Operação Prato, marking a rare instance of government involvement in alleged UFO attacks.
Witness accounts described lights that followed, hovered, and sometimes even emitted beams, reportedly leaving burn marks or causing fainting. The events of Colares remain significant in global UFO history for the scale of the sightings, the physical effects on witnesses, and the seriousness with which authorities treated the reports. The mystery of what truly happened continues to intrigue researchers and the public alike.
The Colares UFO Attacks: Overview
In 1977, Colares Island in Brazil experienced a wave of unidentified flying object sightings that drew both fear and official investigation. Residents reported strange aerial phenomena, physical injuries, and persistent encounters, leading to significant local and national attention.
Location and Timeframe
Colares Island is located at the mouth of the Amazon River in the state of Pará, Brazil. In the late months of 1977, the small fishing community on the island became the center of intense UFO activity.
The incidents took place primarily from August to December 1977. During this period, people across the island witnessed numerous unidentified flying objects. Eyewitnesses described lights and metallic-looking craft appearing suddenly in the night sky, often hovering at low altitude above homes and fields.
Government involvement followed rapidly, with the Brazilian Air Force launching “Operação Prato” (Operation Saucer) to officially document and investigate the increased reports. The geographical isolation and the close-knit nature of Colares made the wave of sightings particularly unnerving for residents.
Chupa-Chupa Phenomenon
The events became commonly known as the “Chupa-Chupa” (literally “Sucker-Sucker”), a term locals used to describe the strange lights believed to extract blood or energy from victims. Witnesses consistently reported beams of light emitted by the UFOs that targeted individuals at night.
These encounters were often accompanied by physical symptoms. Victims noted small burns, puncture marks, and general weakness after being struck by the lights. Medical professionals documented these injuries, adding credibility to the claims.
The terrifying reputation of the Chupa-Chupa led many to fear leaving their homes after dark. Some residents used protective measures like bonfires or homemade shields in attempts to ward off the phenomena.
Scale and Frequency
The number of UFO sightings during this period was unusually high for such a small region. Reports ranged from isolated incidents to entire families or groups observing the objects together.
Several dozen residents eventually reported injuries or health effects linked to their encounters. Below is a simplified summary of incident types:
Type of Report Estimated Number Light Beam Encounters 30+ Physical Injuries 20+ Visual UFO Sightings 80+
Brazilian Air Force investigators collected interviews, photographs, and sketches. The persistent frequency of sightings, sometimes several per night, continued for months before gradually subsiding by early 1978.
Chronology of the 1977 Events
Residents of Colares, Brazil, reported an unusual wave of UFO sightings and attacks throughout 1977. The events drew increasing attention from locals, authorities, and eventually the Brazilian Air Force, resulting in a historic military investigation.
Initial Incidents
In early 1977, people living on the island of Colares began witnessing strange flying objects in the night sky. Locals described seeing solid, luminous shapes—often cigar or disc-shaped—moving silently above their homes and beaches.
Many witnesses claimed to see these objects emitting vivid beams of light. These lights were said to target individuals directly, resulting in a variety of symptoms such as burns, puncture marks, and dizziness.
Within weeks, the number of reports increased. Panic grew as stories of abductions and alien sightings circulated throughout the community. People adapted by staying indoors after sunset, locking doors, and avoiding unlit areas.
Escalation of Attacks
Late 1977 saw a rise in incidents, with over a hundred direct encounters documented. Reports described victims being struck by concentrated beams of light, which locals nicknamed “chupa-chupa” ("suck-suck") due to claims of blood being drawn from the wounds.
Several key points from witness accounts:
Beams produced small, round burns or punctures.
Victims experienced temporary paralysis and extreme fear.
Multiple reports involved groups observing flying objects together.
The scale of sightings led the local mayor to request help. The Brazilian Air Force responded by launching Operação Prato (Operation Saucer), dispatching military personnel to observe, photograph, and document the events. The operation collected photographic evidence and conducted interviews with affected residents.
Aftermath and Consequences
Following intense scrutiny, UFO activity lessened in Colares by early 1978. Locals gradually resumed nightly routines, though some remained fearful of venturing outside at night.
Operação Prato concluded its initial phase, with official statements downplaying the extraordinary nature of the sightings. Many documents and photographs collected by the Air Force remained classified for decades.
The events left a lasting impact on Colares’ population. Psychological effects, persistent rumors of abductions or alien attacks, and distrust of official explanations persisted long afterward. To this day, the Colares UFO incidents remain one of Brazil’s most noteworthy mass sighting cases.
Eyewitness Accounts and Injuries
During the 1977 Colares UFO attacks, multiple residents came forward with specific reports of luminous objects, physical harm, and frightening encounters. The events prompted a formal investigation by the Brazilian Air Force, highlighting both the scale of witness testimony and the seriousness of the reported injuries.
Testimonies from Residents
Eyewitnesses described a series of low-flying, glowing objects over Colares, often appearing in the evening or at night. Many witnesses reported seeing beams of light directed toward the ground or their homes.
Several accounts came from fishermen who saw hovering lights while out at sea. Residents frequently expressed fear and described fleeing inside when the lights appeared.
Testimonies commonly included descriptions of anxiety and a sense of being watched or targeted. Some people linked these experiences to rumors of alien abduction, though no widely confirmed abductions occurred.
Nature of Reported Injuries
The injuries reported were unusual and attracted official attention. Many described burns or puncture marks on their skin consistent with exposure to intense heat or energy. These injuries often occurred immediately after being struck by a beam of light from the unidentified objects.
Symptoms included weakness, dizziness, headaches, and persistent pain at the injury site. Some victims claimed that the wounds would not heal quickly, prompting concerns among local health workers.

Injury Type Reported Symptoms Burns Redness, soreness Puncture Marks Small holes, swelling Weakness Fatigue, dizziness
Close Proximity Encounters
A number of witnesses stated that they saw the craft at close range, sometimes less than 50 meters away. They described physical sensations such as heat, tingling, or partial paralysis when exposed to the beams.
Close proximity encounters were not limited to a single location. In some cases, people trying to repel or evade the lights suffered direct exposure and later displayed injuries.
No official reports confirmed abductions, but fear of such events led many to organize nightly watches or avoid going out after dark. These collective behaviors illustrate the profound impact of the close encounters on daily life in Colares.
Descriptions of UFOs and Aerial Phenomena
Eyewitnesses in Colares reported a diverse range of luminous objects and unusual aerial activity during the 1977 events. These sightings were noted for their consistency over several months and the close encounters experienced by many residents and investigators.
Types of Luminous Objects Observed
Multiple types of unidentified flying objects were documented over Colares. Residents saw flying saucers, disc-shaped objects, and small glowing orbs. Some observers spoke of alien craft shaped like cylinders and rectangular aerial objects, each casting intense, bright light.
A table summarizes the main descriptions:
Type Shape Color/Lighting Flying Saucer Disc-shaped Bright white/yellow Small Orb (Chupa-Chupa) Spherical Blue, red, or white glow Cylindrical Craft Cylinder Metallic with lights Rectangular Object Rectangular block Intense white light
Several witnesses described the objects as emitting beams directed at people or homes, creating glowing areas on the ground or water. The intensity and sharpness of the lights made them distinct from stars or known aircraft.
Flight Patterns and Movements
These unidentified flying objects often displayed flight characteristics different from conventional aircraft. Reports frequently mentioned hovering at low altitudes, sudden quick maneuvers, and instant acceleration. Objects sometimes moved silently, while others generated a faint humming sound.
Common flight patterns included slow passes over villages followed by abrupt stops. Some flying objects darted between trees or hovered over homes for extended periods. Eyewitnesses described the UFOs approaching specific targets before retreating quickly, suggesting purposeful movement.
Many sightings included synchronized movements among multiple luminous objects, coordinating in formation or splitting apart before regrouping. This behavior baffled both locals and military investigators, as it lacked any resemblance to known aerial or natural phenomena.
Official Investigations and Ufology Response
The 1977 Colares UFO incidents prompted a rare blend of government investigation and civilian research. Efforts included direct military involvement, analysis from independent ufologists, and interest from both local and international journalists.
Operation Prato
Operation Prato (Operação Prato) was Brazil’s largest official inquiry into UFO phenomena. Initiated in late 1977 by the Brazilian Air Force, the operation deployed around 30 personnel to the island of Colares. Their tasks involved collecting witness statements, taking photographs, and documenting physical evidence.
The investigators catalogued over 300 reports of strange lights and encounters, including alleged injuries. According to disclosed official records and photographs, team members described objects with unusual maneuvers, bright glows, and apparent electromagnetic effects. The findings, while kept classified for decades, eventually gained attention when some documents were declassified in the 1990s.
Operation Prato stands out for its methodical documentation. Investigators gathered diagrams, sketches, and eyewitness interviews in a manner similar to protocols used in international cases like Project Blue Book in the United States.
Role of Ufologists and Journalists
Brazilian and foreign ufologists played a significant part in following the Colares events. Noted investigators compiled interviews, examined medical records of those allegedly affected, and critiqued the limitations of official inquiries. Some independent researchers asserted the need for scientific rigor, pressing for clearer data on injuries and physical traces.
Journalists helped publicize the events by reporting firsthand on the heightened anxiety in Colares and the official presence in the area. International interest grew as media outlets compared the case to notable American investigations such as the Robertson Panel, which advocated for systematic scientific study.
Ufologists frequently collaborated with residents to track recurring phenomena, sharing their own reports with organizations abroad. The extensive documentation gathered by these groups, often parallel to military files, continues to be referenced in the field of ufology.
Government and Military Reactions
The Brazilian government treated the Colares cases with unusual seriousness. The Air Force and Secret Service coordinated to monitor the situation, but most findings were classified, shielded from public view for years. Official statements tended to minimize panic, rarely acknowledging the more alarming witness accounts of physical effects.
No substantial open cooperation occurred with the FBI or other foreign agencies, though some local officials sought external scientific advice. Airport radar and air traffic controllers in northern Brazil reported tracking unusual aerial phenomena during the peak period, adding credibility to some civilian claims.
After Operation Prato ended, the military abruptly withdrew, and Brazil’s Department of Defense withheld the bulk of collected materials for years. The gradual release of files in later decades allowed limited scientific review, sparking renewed debate over the adequacy and transparency of government responses to UAP incidents.
Physical Evidence and Scientific Analysis
Witnesses and medical personnel in Colares documented direct physical effects on residents and sought to connect these injuries to observed unidentified aerial phenomena. Authorities and researchers also looked for physical traces left behind by the objects and attempted to assess any environmental disturbances.
Medical Reports and Injury Examinations
Doctors on Colares treated numerous residents who claimed to be injured by beams of light from the aerial objects. Symptoms commonly included small burns, puncture wounds, headaches, dizziness, and fatigue.
Medical professionals recorded observations of lesions, consistent with radiation exposure, but tests for known agents such as UV burns or chemical irritants were negative. Many patients exhibited hypothermia despite the tropical climate.
In response, the Brazilian Air Force gathered detailed medical data. Official records reflect both the number and nature of the injuries, though no clear cause was determined with conventional scientific principles. Doctors could not match the injuries to any known environmental factor or disease.
Collection of Material Traces
Efforts were made to collect evidence from alleged landing sites and around homes where sightings occurred. Investigators noted damage to vegetation, including scorched leaves and unusual withering patterns.
Some claims included reports of metallic residues or magnetic anomalies in the affected areas. However, no samples analyzed yielded materials beyond common terrestrial alloys or elements.
The absence of recovered hardware or exotic substances led experts to describe the physical residue of the incidents as inconclusive. No proof of advanced technology or unknown materials was documented in the official findings.
Evaluation of Environmental Effects
Environmentally, locals noted that certain areas experienced sudden changes, such as wilting crops and dead patches in grass following close encounters. Trees and soil were also photographed showing burn marks in patterns reported to match witness descriptions of hovering objects.
A few residents described failure of electrical equipment and temporary interference with radios in the presence of UFOs. These claims were not uniformly documented or scientifically verified.
Researchers considered whether environmental anomalies could be linked to natural causes, such as lightning or localized fires, but specific patterns and timing sometimes aligned too closely with the visual phenomena to dismiss entirely. The Brazilian Air Force concluded that environmental disturbances were real, although their origin remained unexplained.
Types of UFO Encounters in Colares
Reported encounters in Colares during 1977 were highly varied. Many involved physical effects, strange lights, and claims of unusual aerial phenomena linked to alleged extraterrestrial visitors.
Abductions and Medical Exams
Several residents described incidents interpreted as alien abductions. Witnesses claimed they were immobilized by unknown forces, sometimes paralyzed before being taken or examined.
People reported waking up with strange marks, punctures, or bruises. These injuries were often attributed to medical procedures performed by the “beings” inside the craft.
Some told investigators that entities examined their bodies using unknown instruments. The Brazilian Air Force, during Operação Prato, took testimonies from civilians describing detailed accounts of intrusive medical exams, with symptoms like fatigue and dizziness following the encounters.
Beams of Light and Energy Effects
A recurring feature was the sighting of intense beams of light projected from aerial objects. These beams reportedly caused immediate physical symptoms.
Common effects included burns, hair loss, headaches, numbness, and temporary paralysis. According to witnesses, the beams were often directed at individuals from above, leading to local nicknames such as “chupa-chupa” (to “suck” or “draw out”).
Medical professionals documented several cases with similar symptoms. Residents sometimes described these beams as weapons, fueling fears of hostile or “bad” aliens.
Effect Reported Symptoms Burns Reddened skin, pain Paralysis Loss of movement Headaches & Fatigue Weakness, confusion Puncture Wounds Small red marks
Aerial Maneuvers and Levitation
Eyewitnesses regularly saw objects performing abrupt maneuvers, hovering in place, or darting at high speeds. These aerial vehicles could move silently and displayed what was perceived as technologically advanced flight behavior.
Some people described levitation events where bodies or objects were lifted into the air by beams or invisible forces. Reports included accounts of humans being drawn upwards or floating briefly before being released.
A number of accounts also noted clear turbulence and disturbances in the air when the objects moved nearby. Residents identified shapes like discs and cylinders, often surrounded by colored lights, moving with precision uncharacteristic of known aircraft.
Impact on Daily Life and Local Culture
The Colares UFO attacks in 1977 brought sudden changes to the routines, beliefs, and livelihoods of the island’s residents. Fear, confusion, and adaptation were common as strange incidents affected every facet of community life.
Social and Psychological Effects
Witnesses and victims described immediate anxiety and fear following nightly encounters with unidentified lights.
Residents reported:
Difficulty sleeping due to the expectation of further attacks
Children and elders requiring care for distress and unexplained symptoms, such as burns or nausea
Fear of leaving homes after dark, especially in glowing areas reportedly targeted by UFO beams
Health clinics documented a rise in stress-related symptoms and minor injuries, often referred to as results of encounters with the mysterious lights. The Brazilian Air Force’s presence created both reassurance and suspicion, deepening the sense of unease throughout Colares.
Disruption of Fishing and Local Economy
Fishing, the main economic activity in Colares, was severely disrupted. Many villagers refused to visit the beaches or take their boats out at night due to fear of being attacked by the lights.
Fishermen left their nets unused for weeks, which led to:
A sharp decline in local fish supplies
Financial strain for families dependent on daily catches
Changes in local market activity and food availability
Some fishing areas were described as glowing at night, prompting rumors of danger. Economic hardship forced residents to meet basic needs through subsistence farming and informal bartering instead of regular trade.
Integration into Local Folklore
Reports of glowing orbs and "vampire UFOs" quickly blended with Colares’ longstanding folklore traditions. Stories of supernatural beings were reinterpreted, with some residents describing the UFOs as shape-shifting spirits or malevolent entities.
Local storytellers created new tales about:
Light beams that “hunted” the unwary outdoors
Signs and rituals for warding off attacks
Encounters where fishing nets were scorched or vanished mysteriously
These narratives persist in Colares, influencing local festivals, songs, and children’s games. The 1977 attacks became a permanent part of the community's oral history, shaping how new, unexplained phenomena are discussed and understood.
Comparison to Other UFO Incidents
The Colares UFO attacks share striking similarities and distinct differences with other notable UFO cases in the mid-20th century. Reports of strange lights, physical effects, close encounters, and official investigations mark a pattern seen in several prominent incidents across different regions.
Roswell UFO Incident
The 1947 Roswell UFO incident in New Mexico is one of the most famous cases in UFO lore. Debris, described as metallic and unidentifiable, was recovered by U.S. Army personnel. Initial press releases hinted at a "flying disc," but were quickly retracted, leading to decades of speculation about government cover-ups and possible extraterrestrial technology.
Unlike Colares, where witnesses claimed interactions and physical harm, Roswell’s reports centered on physical wreckage and secretive military handling. Roswell also generated a long-lasting cultural impact with ongoing theories, while Colares led to immediate medical concerns and a coordinated military investigation known as Operação Prato.
Incident Witness Injuries Military Response Physical Evidence Roswell No Immediate, secret Debris Colares Yes Immediate, public No debris, effects
Maury Island and Kenneth Arnold Cases
In June 1947, the Maury Island incident involved claims of flying discs dropping material onto a boat near Puget Sound in Washington. That same month, pilot Kenneth Arnold reported seeing nine high-speed objects near Mount Rainier, sparking the term "flying saucer." These two events led to increased military and media attention in the United States.
The Colares case stands apart because of widespread community effects and health problems, while Maury Island and Arnold’s sightings involved few direct witnesses and little physical aftermath. However, both set a precedent for military response and skepticism, prefiguring the official scrutiny experienced in Colares.
Lubbock Lights and Green Fireballs
The Lubbock Lights of 1951 involved formations of mysterious blue-green lights flying over Texas, observed by scientists and residents alike. Around the same era, the Green Fireballs sightings across the American Southwest were investigated by military and scientific agencies. These lights were characterized by unusual speeds, colors, and behaviors not easily explained by known phenomena such as ball lightning.
Colares UFOs also exhibited agile movements and intense lights. The Brazilian military recorded witness testimonies and even photographed the objects, much like U.S. agencies tried to document and explain the Lubbock and Green Fireballs phenomena. Both cases highlight the role of official efforts to analyze and address unexplained aerial sightings, though Colares included claims of physical injury not present in the U.S. cases.
Antonio Villas Boas and William Gill
In 1957, Antonio Villas Boas, a Brazilian farmer, claimed an abduction by humanoid beings and described a detailed encounter inside a spacecraft. Separately, in 1959, William Gill, a missionary in Papua New Guinea, and several others observed hovering discs and humanoid figures waving from above. These cases belong to the close encounter category—direct interaction with alleged occupants rather than mere observation of lights or objects.
Both Boas and Gill’s cases echo the Colares reports in terms of human contact and detailed witness testimony. In Colares, many residents recounted close-range experiences and physical aftereffects, similar to the health effects claimed by Villas Boas. Visual contact with apparent beings, seen in Gill’s case, is reminiscent of descriptions from Colares, further supporting the uniqueness of direct contact reports in the global context of UFO incidents.
Legacy of the Colares Incident
The Colares UFO attacks of 1977 became a defining episode in both Brazilian history and the global study of unexplained aerial phenomena. The event's aftermath was marked by official investigations, ongoing public fascination, and numerous discussions in scientific, military, and ufology communities.
Influence on Ufology
The Colares incident was pivotal for ufology due to its scale and the extensive official documentation produced by the Brazilian Air Force under Operação Prato. Investigators collected photographs, sketches, and testimony from dozens of witnesses as part of their report.
These efforts gave the case a unique level of credibility. The number of people affected, including those with physical symptoms such as burns and puncture marks, remains unusual in global UFO encounters.
Researchers and writers continue to reference the event in books, documentaries, and conferences. It is often cited alongside other notable cases in ufological literature.
The openness of the Brazilian military compared to other countries added further legitimacy, encouraging other nations to re-examine their own UFO policies.
Continued Research and Public Interest
Decades after the events in Colares, the case is still discussed in both academic and popular circles. Declassified documents and interviews with Operação Prato officials have brought new details and perspectives.
Media coverage, including documentaries and news stories, ensures that public interest stays high. Researchers frequently revisit the original files for analysis.
The Brazilian government’s willingness to release information has made Colares a point of reference in debates about transparency. Public requests for scientific inquiry into the incident—and into UFO sightings in general—have led to calls for increased openness worldwide.
International UFO organizations often revisit Colares when advocating for more rigorous study and official investigation of unexplained aerial phenomena.
