October 1974 --One three month old specimen currently in custody retrieved from Congo. Bone structure, height and behaviour seem to indicate relation to the Moa; however, it more closely resembles the Jurassic Aepyornis maximus. Fossil remains found in a limestone quarry from the Jurassic period in Argentina have been acquired and is a match for this live specimen, code named Thunderbird. In 1971, a very large feather was found in the Congo by biologist Samuel Cartesian, who was there to study egrets of the Nile and southern marshes of Egypt and the Congo. He stated that he had seen a large bird with upwards of a six metre wingspan within an unspecified region of the Congo. Cartesian returned to Oxford with this feather specimen, which was 1.5 metres long and 1.85 centimetres wide. The feather was acquired by this organisation for evaluation against our specimen. While our test subject did not live past the age of 17 months of age, it did appear to have a very similar feather structure. Examinations of the deceased carcass showed that while the bird had the physical capability of flight, its musculature was not fully formed for the task. As it grew into adulthood, its wings dragged upon the ground, and no attempts to use them for flight were seen. In the wild, it is questioned whether the wings would be used, or if they would serve as a detriment in escape to predators.

February 1982 – Four specimens of Thunderbirds escaped laboratory controls during flight testing, and were sighted by civilians in Illinois. Live capture proved impossible, and they were accidentally killed by an overdose of tranquilliser.

July 1991 – New genetic specimen Cloud Dragon escaped from development lab during routine transport to Los Alamos. Sighted in Texas, teams found, captured, and returned it to laboratory conditions. It suffered from emotional trauma and was found dead by self-means shortly thereafter.

October 2002 -- On two separate occasions (the 10th and 16th) "a giant winged creature like something out of Jurassic Park" was reported by wire services out of reports generated by the Anchorage Daily News. A pilot en route to Manokotak, Alaska calculated its wingspan to match the length of one wing on his Cessna 207, which is roughly 5 metres. Other sightings from these days reported similar wingspan.

June 2004 – Three researches funded by private organisation “National Geographic” sent into deep Congo to research reports of a abnormally large bird reportedly similar to the Moa that seems to have been domesticated by a native tribe. The last reported sighting of this tribe was 30 years ago, and 30 years prior to that. However, no research or investigation has found significant evidence to connect the large bird to the tribe.
