Mauduyt (1783: 637) mentions a variety of the Coucou de Cayenne, which Brisson called the ‘ Petit Coucou de Cayenne’, now Piaya melanogaster (Vieillot, 1817), noting that this variety is much rarer, given the few specimens brought back to France compared to those of the Coucou de Cayenne. This suggests that by 1783, Piaya cayana was a common species imported into France, which may explain why there are two ‘ Buffon’ specimens of this species in the Baillon Collection.	en	Gouraud, Christophe (2026): Buffon’s specimens in the Baillon ornithological collection (La Châtre, France) and their potential connection with Martinet’s Planches enluminées.

03EF1F5CC954FFCA6FE5537EFC4513CB.taxon	discussion	COMMENTS. — The inscriptions under the pedestal of this specimen do not indicate a direct link between Buffon and Baillon but simply state that the bird was donated by the MNHN. The specimen has its plumage identical to that of the bird depicted in plate 973 (i. e., adult), and the provenance (Cayenne) matches with both HNO and the plate. As we have seen, by the late 18 th century and into at least the first decade of the following century, the MNHN had parted with a large number of old specimens. Therefore, it is entirely possible that this specimen dates from the Buffon era. It could have been the bird used by Martinet and, consequently, may be the holotype of Pelecanus leucogaster Boddaert, 1783.	en	Gouraud, Christophe (2026): Buffon’s specimens in the Baillon ornithological collection (La Châtre, France) and their potential connection with Martinet’s Planches enluminées.

The bird was therefore collected before December 31, 1778. Buffon and Guéneau de Montbeillard only treat herons in volume VII, published in 1780, two years after this specimen was sent to Emmanuel Baillon. None of the Ardeidae Leach, 1820 depicted in the Planches enluminées correspond to this specimen. The closest description found in HNO is that of the Crabier Pourpré and that of the Héron Pourpré du Mexique in Brisson’s Ornithologie, although the provenance does not match the Baillon specimen. Sharpe & Ogilvie-Grant (1898: 231) also question the correspondence of the birds described by Buffon and Guéneau de Montbeillard, as well as Brisson, with Ixobrychus exilis (Gmelin, 1789).	en	Gouraud, Christophe (2026): Buffon’s specimens in the Baillon ornithological collection (La Châtre, France) and their potential connection with Martinet’s Planches enluminées.

It could therefore have been the bird used by Martinet and, consequently, be a syntype of Picus rubricollis Boddaert, 1783. A type series is here justified because Boddaert also refers to the Red-necked Woodpecker of Latham (1782: 558), who himself not only refers to Buffon and Guéneau de Montbeillard’s text and plate 612, but also to a specimen from the Leverian Museum (said to also come from Cayenne).	en	Gouraud, Christophe (2026): Buffon’s specimens in the Baillon ornithological collection (La Châtre, France) and their potential connection with Martinet’s Planches enluminées.

Therefore, it is entirely possible that this specimen dates from the Buffon era and that it was used by Martinet. As a result, it could well be the holotype of Picus flavigula Boddaert, 1783. Boddaert also refers to the yellow-headed Woodpecker of Latham (1782: 595), but Latham refers to Buffon and Guéneau de Montbeillard’s text and plate 784, hence no type series involved here, but a single specimen.	en	Gouraud, Christophe (2026): Buffon’s specimens in the Baillon ornithological collection (La Châtre, France) and their potential connection with Martinet’s Planches enluminées.

In Buffon’s case, diurnal birds of prey are treated as early as the first volume, published in 1771. It is highly likely that the first specimen of this species did not reach Buffon’s hands until after the publication of the HNO volume dealing with diurnal raptors, i. e., the very first volume, which was published in 1771 (though, as we have seen, the text was ready in 1770).	en	Gouraud, Christophe (2026): Buffon’s specimens in the Baillon ornithological collection (La Châtre, France) and their potential connection with Martinet’s Planches enluminées.

03EF1F5CC94AFFD16FC952BEFE1E13CA.taxon	discussion	COMMENTS. — This specimen (male) and the bird depicted on plate 745 (male) – holotype of Pipra peruviana Latham, 1790 – are quite similar. However, according to Mauduyt de la Varenne (1783: 622), the bird used by Martinet for the drawing of plate 745 was sent to him by Pedro Franco Dávila, then director of the Natural History Museum of Madrid, to be prepared with the intention of being exhibited in the galleries of the Madrid museum. After being mounted by Mauduyt de la Varenne, the bird would have been studied by Martinet before being sent back to Madrid. If this is the case, the Baillon specimen cannot be the bird depicted on plate 745. The Madrid collections do not currently have any pre- 1800 specimens (Steinheimer 2005), with the possible exception of Struthio camelus eggs (Josephina Barreiro Rodríguez in litt. November 17, 2022), and no bird from the Dávila collection seems to have survived (Roselaar 2003). In 1767, Dávila’s ornithological collection was poor (only a few specimens) and did not include any Rupicola (Dávila 1767: 490 - 491). Since plate 745 was only published ten years later, it can be assumed that Dávila acquired this species between 1767 and 1776. Unverifiable but not excluded, Dávila could have sent several specimens to Mauduyt de la Varenne, so that he could keep one or two as a token of appreciation and send the rest, mounted, back to Spain. Assuming that the Baillon specimen is not the bird depicted by Martinet, which indeed seems to be the case, it is reasonable to think that it was collected after the publication of the Planche enluminée and the accompanying text, i. e., after 1778. A collect during Charles-Nicolas-Sigisbert Sonnini de Manoncourt’s (1751 - 1812) expedition to western French Guiana, up to the Rio Negro, in 1773 - 1774 seems unlikely, especially since this exploration does not appear to have gone far enough west to encounter this species. Likewise, a collection by Joseph de Jussieu (1704 - 1779) during his long stay in Peru and Ecuador is excluded, as he left this country in October 1770, having lost his collections (Judde 2005: 74). Among the possible origins of the Baillon specimen is the trip to Peru by French naturalist Joseph Dombey (1742 - 1794), along with Spanish Hipólito Ruiz López (1754 - 1816) and José Antonio Pavón (1754 - 1840), between 1777 and 1785. These travelers explored regions to the east of Lima where this cotinga could have been collected or purchased at a local market, either in Tarma between May 1779 and January 1780, or in Huánuco between April 1780 and March 1781 (Lang 1985). Although this expedition was primarily focused on botany (Pinault Sørensen 2005: 51), it cannot be excluded that some animals, including brightly colored birds such as a male Rupicola peruvianus, were acquired to be brought back to France. Finally, since Dávila held his position as director of the Madrid Natural History Museum until his death in 1786, it cannot be ruled out that he received specimens from Peru between 1778 and 1786 and sent a few examples to his former colleagues in Paris.	en	Gouraud, Christophe (2026): Buffon’s specimens in the Baillon ornithological collection (La Châtre, France) and their potential connection with Martinet’s Planches enluminées.

03EF1F5CC948FFDE6C47511CFEE11671.taxon	discussion	COMMENTS. — This specimen and the one depicted by Martinet do not resemble each other, and their provenances are different (Cayenne for the Baillon specimen vs Saint Thomas for the bird on plate 535 fig. 2). Its posture is quite similar to the figure in Brisson, but a pre- 1760 collection is, here, quite unlikely. REMARK As we have seen, certain factors can make it difficult (if not impossible) to link for certainty a specimen as a model for a Planche enluminée. Therefore, the conclusions drawn from comparing a Planche enluminée with a ‘ Buffon’ specimen – hence a potential type (ICZN 1999: Art. 12.2.7) – must be made with caution. In reality, only a handwritten note from Buffon or from his contemporaries, accompanying a specimen and stating that it is the bird used for the depiction on the plate, would allow us to assert with (almost) certainty that this specimen is indeed the one used as the model for the Planche enluminée.	en	Gouraud, Christophe (2026): Buffon’s specimens in the Baillon ornithological collection (La Châtre, France) and their potential connection with Martinet’s Planches enluminées.
