New findings of birds in paleontological and archaeological contexts of Cuba

With great excitement here I announce the publication of another contribution to the archaeology and paleontology of the island of Cuba. On this occasion as a collaborator to Osvaldo Jimenez, zooarchaeologist, a specialist from the Office of the Historian of the City of Havana, Cuba. Our paper came out today on the scientific journal Novitates Caribaea, available here:

Bilingual abstract: 

 This paper provides new records on Cuban birds such as the endemic Cuban macaw (Ara tricolor), found in two archaeological sites in Old Havana dated in the 17th and 18th centuries. We provide details on Arredondo´s owl (Pulsatrix arredondoi), extinct since prehistory, but whose remains have been collected in two caves near Las Charcas, a community in San José de las Lajas municipality, Mayabeque province. The report also includes the ivory-billed woodpecker (Campephilus principalis), from a specimen collected in Cueva del Aguacate in the above-cited location. The bone remains found in Cueva de Las Charcas match a paleontological context, but the other was found in la Cueva de los Muertos, an archaic culture archaeological site (i.e., hunter-fisher-gatherers). The possibility that P. arredondoi formed part of this pre-Columbian aboriginal’s diet is considered. The record of C. principalis represents the first finding of this species in paleontological contexts in Cuba. Information on the natural history of the species is moreover provided.

 Se comentan nuevos registros de aves de Cuba, como el guacamayo cubano (Ara tricolor), hallado en dos sitios arqueológicos de La Habana Vieja, de los siglos XVII y XVIII, asimismo, el búho de Arredondo (Pulsatrix arredondoi), ave extinta en tiempos prehistóricos, cuyos restos hemos colectado en dos cuevas de la comunidad Las Charcas, municipio San José de las Lajas, provincia Mayabeque, y por último, el carpintero real (Campephilus principalis), colectado en la Cueva del Aguacate, sitio localizado también en la comunidad Las Charcas. El resto óseo de P. arredondoi colectado en la Cueva de Las Charcas procede de un contexto paleontológico. En cambio, el otro resto proviene de la Cueva de los Muertos, que es un sitio arqueológico de aborígenes arcaicos, también conocidos como apropiadores mesolíticos. Por vez primera se considera la posibilidad de que P. arredondoi formara parte de la dieta de los aborígenes precolombinos citados. El registro de C. principalis representa el primer hallazgo de esta especie en contextos paleontológicos de Cuba. Adicionalmente se aporta información novedosa sobre la historia natural de las especies tratadas.

Our new paper on Greater Antillean land mammal extinctions is published!

With great pleasure (and relief after nearly a decade of research) here I announce the publication of our paper Assessing the role of humans in Greater Antillean land vertebrate extinctions: New insights from Cuba on the journal Quaternary Science Review. Also, here is a link for its free download to all parties interested, in the next fifty days. 

I take this opportunity to thank all the coauthors of this paper, Ángelo Soto Centeno, Lázaro W. Viñola, Osvaldo Jiménez, Odlanyer Hernández de Lara, Logel Lorenzo, and Alexis Mychajliw – all respected specialists in their fields – for their significant contribution and participation in making this dream come true. Thank you. 

Here is a brief abstract: 

The Caribbean archipelago is a hotspot of biodiversity characterized by a high rate of extinction. Recent studies have examined these losses, but the causes of the Antillean Late Quaternary vertebrate extinctions, and especially the role of humans, are still unclear. Previous results provide support for climate-related and human-induced extinctions, but often downplaying other complex bio-ecological factors that are difficult to model or to detect from the fossil and archaeological record. Here, we discuss Caribbean vertebrate extinctions and the potential role of humans derived from new and existing fossil and archaeological data from Cuba. Our results indicate that losses of Cuba’s native fauna occurred in waves: one during the late Pleistocene and early Holocene, a second during the middle Holocene, and a third one during the last 2 thousand years, combining the arrival of agroceramists and later of Europeans. The coexistence of now-extinct species with multiple cultural groups in Cuba for over 4 thousand years implies that Cuban indigenous non-ceramic cultures exerted far fewer extinction pressures to native fauna than the later agroceramists and Europeans that followed. This suggests a determinant value to increased technological sophistication and demographics as plausible effective extinction drivers. Beyond looking at dates of first human arrival alone, future studies should also consider cultural diversity with attention to different bioecological factors that influence these biodiversity changes. 

Highlights

Cuban land mammal extinctions occurred in several waves after the middle Holocene, most intensively during the last 2000 thousand years

Cuba lost nearly half of its land mammal fauna during the late Amerindian subinterval (< 1500 thousand years)

Most important extinction episodes occurred after the arrival of agroceramist cultures, and later, Europeans

Cultural diversity, demographics, technological sophistication, and naturally occurring factors must be considered in human-induced extinction models

Future extinction models must consider the complex and concomitant combination of bioecological and climatological factors

Con gran gusto – y después de casi una década de investigación – anunciamos la publicación de nuestro artículo “Assessing the role of humans in Greater Antillean land vertebrate extinctions: New insights from Cuba” (Evaluación del papel de los seres humanos en la extinción de vertebrados terrestres de las Grandes Antillas: nuevas perspectivas desde Cuba) en la prestigiosa revista Quaternary Science Review. Aprovechen y compártanlo con los amigos y colegas que les interesen estos temas. Tomo este momento para agradecerle a los coautores Ángelo Soto Centeno, Lázaro W. Viñola, Osvaldo Jiménez, Odlanyer Hernández de Lara, Logel Lorenzo y Alexis Mychajliw por su arduo trabajo y participación en hacer este sueño realidad.

Resumen del trabajo:

El archipiélago caribeño es un “punto caliente” de biodiversidad caracterizado por una alta tasa de extinción. Los estudios recientes han examinado estas pérdidas, pero las causas de las extinciones de vertebrados del Cuaternario tardío de las Antillas, y especialmente el rol de los seres humanos, aún no están claros. Los resultados anteriores brindan apoyo a las extinciones inducidas por el hombre, pero a menudo se minimiza otros factores bioecológicos que son difíciles de modelar o detectar a partir del registro arqueológico o fósil. Aquí discutimos las extinciones de vertebrados en las Antillas Mayores y el papel que han jugado los humanos en las extinciones más recientes desde la perspectiva de datos arqueológicos y paleontológicos de Cuba. Nuestros resultados apoyan la hipótesis de que las pérdidas de la fauna nativa de Cuba ocurrieron en ondas: una durante el Pleistoceno tardío y el Holoceno temprano, una segunda durante el Holoceno medio, y una tercera durante los últimos 2 mil años. Estos dos milenios resultan ser los más importantes, combinando la llegada de los agroceramistas y luego de los europeos como importantes golpes a la fauna. La coexistencia de especies ahora extintas con múltiples grupos culturales en Cuba por más de 4 mil años implica que las culturas indígenas no-ceramistas ejercieron menos presiones de extinción sobre la fauna nativa que las agroceramistas y los europeos que siguieron. Esto sugiere un valor determinante para la sofisticación tecnológica y la demografía vías importantes de extinción. Más allá de mirar las fechas de la primera llegada humana, los estudios futuros también deben considerar la diversidad cultural y atención a diferentes factores bioecológicos que influyen en los cambios de biodiversidad.

When did the turkey vulture arrive in Cuba?

All the American vultures belong to the Cathartidae, a neotropical endemic and diverse bird family of carrion scavengers. Currently, the family is integrated by four buzzard-like vultures and three condors including the turkey vulture (Cathartes aura), the black vulture (Coragyps atratus), up to the California condor (Gymnogyps californianus) and the Andean condor (Vulture gryphus).

 
Of these New World vultures, the genus Cathartes is the most diverse with three species, C. burrovianus, C. melanbrothus, and C. aura. Of these, the turkey vulture Cathartes aura, along with the black vulture Coragyps atratus, are the most widespread, inhabiting nearly all the American continent and parts of the West Indies, including the island of Cuba. Turkey vultures abound on the island and is easily observable today. But when did it reach Cuba? When did it become part of its fauna? Was it before or after the arrival of Europeans?

Cathartidae fossils are known in the New World, confidently, since at least late Miocene, and more so during the Pliocene-Pleistocene epoch, meaning during the last 6 million years. Interestingly, fossil Cathartidae have been reported from the late Oligocene (~23 million years) of Mongolia (Emslie, 1988). With such a long fossil record, one would think that the presence of the turkey vulture in Cuba spans to the Pleistocene. At least, that was what was originally thought by Cuban paleontologists.

The source of uncertainty is because turkey vultures seem to have a poor fossil record in Cuba. Several remains found in cave deposits near the capital city of La Habana, in Cueva Lamas and Cueva del Túnel, were at first interpreted as Late Pleistocene in age (see Arredondo, 1984). These specimens were later revised by the Cuban paleornithologist extraordinaire, William Suárez, who concluded that these were modern specimens and not fossil material (mixing of bone remains in caves is a common phenomenon, and one must be extra careful in discerning what is a fossil, or subfossil, and what is modern).

Based on the research of the Cuban zooarchaeologist Osvaldo Jiménez, turkey vulture remains have been identified in early 17th-century colonial contexts of La Habana Vieja (Old Havana), which agree with documentation of the time. Jiménez argues that the species was already considered common in Jamaica by 1680, where it adopted the name of John Crow. It was from this island that the species spread into Cuba, Hispaniola, and Bahamas, becoming established by the late 18th century. It was further introduced in Puerto Rico during the 19th century for sanitary reasons (Jiménez and Arrazcaeta, 2008).

Two important accounts document the presence and widespread of the turkey vulture in Cuba during the colonial period. One is a mention made by the governor of the eastern department of Cuba, Juan Garcia de Navia Castrillón, in June of 1617. The other is a watercolor sketch made by soldier Henry Fletcher in august 1762, during the Siege of Havana by the British (see figure below). This illustration brings an interesting note that reads “head of a turkey buzzard or carrion crow, a fowl common in the West Indies. The body resembles very much a large brown turkey”.  Both accounts support the apparent widespread of this species on the islands by then.

More recently, however, during our excavations of Cueva de los Nesofontes at Palenque Hill (source of several posts in this blog, available here and here), we encountered several unequivocal Cathartes aura subfossil remains in beds dated to less than a couple thousand years before the present (Orihuela, 2019). These fossils seem to reinstate that the turkey vulture was present in Cuba before European arrival for at least several thousands of years.

This makes sense biogeographically, due to the proximity of the Greater Antilles and the continental mainland. In fact, many of the turkey vulture groups that migrate between parts of the continents, do so by flying over the same span of Caribbean ocean (Moore, 2000). Moreover, fossils of the species have also been found in Bahamian sinkhole deposits (Ficus Pit, in San Salvador, see Olson et al., 1990). Olson and colleagues reached the conclusion, as we do here, that turkey vultures likely arrived in the Greater Antilles due to natural expansion, especially after the extinction of many of the islands large and diverse raptors probably during the Holocene.

Ara tricolor: Cuba's extinct endemic macaw

Up to 150 years ago Cuba possessed three parrots in its avifauna-one of them a large and beautifully colored macaw.

Parrots belong to the bird family Psittacidae, of which Cuba has two representative genera and species: the endangered Cuban conure Psittacara eups (=Aratinga), and the better widespread Cuban parrot Amazona leucocephala. Up to the mid-XIX, Cuba also had a large macaw, Ara tricolor. The last known pair was shot in 1864 at La Vega, in the Cienaga de Zapata-the largest wetland swamp of the Caribbean archipelago. The ornithologists Johannes Gundlach and C. B. Cory believed that this species survived up until the later XIX century. In Spanish, these large parrots are known as guacamayos, which is the Arawak indian name, or papagayos, the Castilian.

Scientist recognize that other large Ara macaws existed in other islands of the Caribbean, but the Cuban macaw is the only one known from complete specimens, preserved as stuffed, mounted, or skins, and several skeletal parts found in paleontological and archaeological deposits.

Colonists that came to the island after Columbus’s rediscovery of the New World, documented the massive killings of these birds by amerindians, but mostly by conquistadors, who used them for food, plumage, or kept them as pets. In one occasion, Father Bartolome de las Casas records a mass killing of macaws at the indian town of Casaharta in 1513 by the natives for the sake of the colonists:

“[my translation] …the many things marvelous and abundance of food from many sources, bread and game, and fish, but above all of macaws, which if I have not forgotten, during the 15 days that we were there, at least 10,000 macaws were eaten. These were of the most beautiful in the world, which was a real shame to see them killed. Even the little native kids would climb trees to catch them…”
 
Las Casas also recorded the presence of a “different” macaw, with a white, not red, forehead on the island of Hispaniola. He mentions that when Columbus reached the island of Cuba, “nice, green macaws” were gifted to him by the natives (Las Casas, 1875:296, vol. 1). The colonists accepted these gifts, and many macaws were sacrificed for their beautiful feathers, which were to be sent to Spain as exotic souvenirs.

It seems, by these accounts, that the Caribbean amerindians were also fond of keeping parrot pets. Yet still, during these early years of the conquest, “there were so many flocks of parrots, that they covered the sun”. This was not to last past the colonial era.

The causes of its final extinction are closely tied to human pressure: overhunting at first, and later, deforestation for agricultural development, most intensified during the XVIII and early XIX. During this time, the king’s preserves of forests were maintained and untouched until then by Real decree and accessed only illegally or under special grant by the king. But with the massive onset of agriculture deforestation for tobacco and sugar cane plantations likely drove these large birds to the few remaining forests of the island, Cienaga de Zapata being one of them, and one of the most protected even now. It was at these locations that a few naturalists secured the last specimens, treasures of American and European museums. Sadly, the only surviving mounted skin of Ara tricolor in Cuba was recently stolen from the Institute of Ecology and Systematics (IES) in the outskirts of the city of Havana. This was a gorgeous well-preserved specimen collected by Johannes Gundlach, and one of the most treasured specimens of the old Academy of Sciences, which are now housed at the Institute.

These rare representatives of Cuban macaws belong in museums, were they are taken care by specialists, people who have studied their whole lives to preserve specimens such as these, and where they are kept under special conditions, and where they can be studied by those that are interested. They do not belong in some collector’s cabinet. It is only hoped that the final itinerary of this specimen is secured, and that the collector protects the beautiful mounted specimen with the dignity it deserves-for the rarity it represents, and as a reminder of the vulnerability of the Earth’s fauna before human destructiveness.
