Endangered species may have been part of ancient funeral feasts in Morocco cave
On the northern peninsula of Morocco, just across the sea from Spain, one of the world's heaviest flying birds faces extinction. The population of great bustards, Otis tarda, is now down to less than 80 individuals, with some experts estimating the species will go extinct on the African continent by 2036. This wasn't always the case, however, and a new analysis from deep inside an ancient cave shows the birds may once have been plentiful — and used in ritualistic feasts. The Grotte des Pigeons is a large, open air cave that has hosted human occupation for at least 85,000 years, ending about 14,600 years ago, according to a study published March 18 in the peer-reviewed journal Ibis. For centuries, the cave was used as a burial ground, now known as 'Africa's oldest identified cemetery,' according to the study. Researchers have been studying the site for years because of the 'exceptional detail' of the preserved remains, but as they sifted through the bones, they realized not all of them belong to humans. From 2005 to 2022, researchers uncovered 150 bird remains belonging to at least 14 species, including some belonging to great bustards, according to the study. Some of the bustard remains show evidence of being butchered and cooked, with cut marks similar to those made on modern-day turkeys after Thanksgiving, researchers said in an April 16 news release from the Natural History Museum in London. Bustards are incredibly large birds, with some males of the species reaching nearly 45 pounds, so hunting and preparing them for consumption would not have been an easy task, researchers said. 'A specialist of open grasslands and farmland, the great bustard requires equally massive areas of relatively undisturbed land to live and breed on,' according to the release. These areas are not physically close to the cave, meaning the birds were intentionally brought into that space, researchers said. 'This is a communal behavior that involves special foods that people have to go out of their way for that is then consumed in some kind of special context,' study author Joanne Cooper said in the release. 'The habitat for the great bustard isn't really the kind of the mountainous area around the cave in which the remains are found. They would have had to trek down to the plains to catch the bustards, carry them back up to the cave, prepare them, cook them and eat them. The special context is that they're associated with these burials.' The bird remains, dated to about 15,000 years ago, were not only eaten (evidenced by teeth marks on bones) but also left as offerings with the dead, according to the study. Meat-rich parts of the bird were found near the feet and legs of a human male, intentionally left while other parts of the bird were consumed by the living, according to the study. 'We see a strong cultural association with the great bustard because the people are not only depositing them in burials, but there's also evidence that they were eating them as well,' Cooper said. 'We believe that was part of the funeral rites. It seems to be a feasting set up, which is a very specific type of ritual eating.' Great bustards are listed as endangered worldwide by the International Union for Conservation of Nature, and are found outside Morocco in Spain, a few small populations in central Europe, western Asia, and in northern China and Mongolia. The population in Morocco is the only group of great bustards in Africa, and researchers said because of their genetic difference to the Spain population, there was previous debate about how long great bustards have lived on the continent. 'This new finding confirms that the birds have a long history on the African continent, and were much more abundant and widespread than they are today,' according to the release. The Grotte des Pigeons cave is located outside the town of Tafoughalt, in northeastern Morocco. The research team includes Cooper, Nigel Collar, Abdeljalil Bouzouggar, Nick Barton and Louise Humphrey.

Ancient funerals may have included a ritual feast on a giant bird
Ancient humans living about 15,000 years ago in present day Morocco may have ritualistically feasted on some of the world's largest birds as they buried their dead. The butchered bones of great bustards (Otis tarda) that were recently discovered in one of the African continent's oldest cemeteries hint that these avians were culturally significant at the time. The findings are detailed in a study recently published in the journal IBIS. Roughly 14,700 years ago, a group of people were living and burning their dead in a cave located in what is now Morocco. Called Taforalt cave, or Grotte des Pigeons, this site contains graves of over 30 ancient humans. During this time, mammoths were still grazing the northern steppes and sheep would not be domesticated for another 5,000 years or so. This group was beginning a transition between a semi-nomadic and a more settled life. Studying the other objects found within their graves offers scientists an insight into their daily lives and culture as a community. Additionally, the environmental conditions in the cave preserved the bones, tools, and a huge range of biological material. Having access to this kind of DNA evidence allows for researchers to build a more detailed picture of their lives. Earlier work found that they were burning and consuming the medicinal plant Ephedra, along with other foods such as juniper and acorns. [ Related: Butchered skulls point to Europe's Ice Age cannibals. ] Recent findings suggest their death rituals included the great bustard. Bustards are among the largest flying animals on the planet, with males regularly weighing in at about 44 pounds. Bustards still exist today, but they were once more widespread across Europe, Asia, and parts of north Africa. The new evidence found in this cave confirms that the birds have a long history on the African continent–and have long been valued by humans. 'We see a strong cultural association with the great bustard because the people are not only depositing them in burials, but there's also evidence that they were eating them as well,' Joanne Cooper, a study co-author and senior curator of the avian anatomical collections at the Natural History Museum in London, said in a statement. 'We believe that was part of the funeral rites. It seems to be a feasting set up, which is a very specific type of ritual eating.' The bones of butchered and cooked animals have been found in the most high-status graves. Some hold the skulls of wild sheep, but one specific burial has the breastbone, a great bustard with cut marks. The team believes that this is evidence of a meal similar to the turkey eaten on Thanksgiving Day or Christmas now. The repeated presence of great bustard remains suggests that the avians were culturally significant. It would have taken a great deal of valuable time and effort to catch and prepare the animals, which suggests ritual feasting over routine behavior. 'This is a communal behaviour that involves special foods that people have to go out of their way for that is then consumed in some kind of special context,' says Cooper. 'The habitat for the great bustard isn't really the kind of the mountainous area around the cave in which the remains are found. They would have had to trek down to the plains to catch the bustards, carry them back up to the cave, prepare them, cook them and eat them. The special context is that they're associated with these burials.' Great bustards are typically found in open grasslands and farmland, requiring large areas of undisturbed land for breeding and living. Their breeding typically occurs in March, when males will reveal themselves to females. They compete for female attention with elaborate displays and violent fights in an area known as a lek. They were already naturally vulnerable to human disturbance because they need so much space, but have also been hunted for both food and sport. This hunting and habitat destruction has significantly fragmented their population. The only population seen in Africa today is in Morocco, where the species is considered critically endangered. This group is closely related to a population in Spain, but also genetically distinct. Still, there has been some debate among biologists about how long great bustards had lived in north Africa. In northwestern Morocco, about 70 birds live in two small areas, but this new evidence indicates that their presence goes back generations. The team hopes that the discovery showing the ancient human connection to great bustards spurs more conservation efforts to keep this population from going extinct.
