Can You Identify the Crypturellus Obsoletus Subspecies?

• Félix de Azara was a Spanish engineer and naturalist who traveled to Paraguay between 1781 and 1801.
• Azara's informal description of "Ynambu bleuâtre" based on sixteen individuals collected during his trip was the first mention of this species in the literature.
• In 1815, the species was formally described by Temminck under the name Tinamus obsoletus.
• Pinto (1964) restricted the type locality to around São Paulo city, Brazil.
• Crypturellus obsoletus was first illustrated in 1838 in Temminck & Chartrouse’s “Nouveau Recueil de Planches Coloriées d'Oiseaux”.
• Crypturellus obsoletus has several subspecies, including C. o. hypochraceus, C. o. punensis, C. o. castaneus, and others.
• Laverde & Cadena (2014) proposed that C. o. castaneus should be treated as a distinct species based on remarkable vocal differences and distinct elevational range.
• The taxonomy of the C. obsoletus complex has attracted little attention in the last decades.
• Some taxa, such as C. o. castaneus in Colombia, are threatened.
• No specific conservation program is directed towards them, partly because of the lack of comprehensive taxonomic studies.
