“…Ave no voladora originaria de Sudamérica 4 y la de mayor tamaño del continente, el ñandú ocupa un lugar distintivo en la etnoclasificación qom del mundo zoológico, siendo el único integrante de la categoría maỹo que lo aparta del resto de aves (Medrano, 2017). Junto al guazuncho (Mazama gouazoubira), guanaco (Lama guanicoe), ciervo de los pantanos (Blastocerus dichotomus) y tapir (Tapirus terrestris), el ñandú se encuentra estrechamente ligado a la tradición cazadora y manejo del ambiente en las praderas chaqueñas (Métraux, 1944).…”

Based on the ethnography of qom (toba) communities living on the right bank of the middle Bermejo River, in the ArgentineChaco, I address the relationship of this people with the ñandú (Rhea americana), a bird native to South America and closelylinked to the hunting tradition in the Gran Chaco. I argue that beyond the hunting activity, this relationship is inscribed in the Chaco landscape, in the memories, cosmology and celebrations of the qom people. This case is framed by the contemporary anthropological debate on the classic opposition between practices and ethos of domestication and hunting, that I approach from the context of indigenous feasts and their ability to congregate in the same space-time human relations and prominent links with plant and animal species. I conclude that the qom’s proximity to the images and body of ñandú, beyond turning the bird into an object of human hunting or significance, allowed them to understand the way of dealing with transformations configured by the alternation between abundance and scarcity, as extremes that shape the landscape and life in the Chaco.

“…The South‐west Atlantic Ocean has several marine fronts located mainly in areas with intermediate sea surface temperatures, neritic waters and convergence zones (Acha et al, 2015; Violante, Laprida & García Chapori, 2017). Some seabird species breeding in the region of South‐west Atlantic Ocean and in other areas of the globe are known to forage in these frontal areas that are also intensively used by the fishing industry (Acha et al, 2004; Favero & Silva Rodriguez, 2005; Navarro, Rozycki & Monsalvo, 2014). The most abundant albatross of the South‐west Atlantic Ocean is the black‐browed albatross Thalassarche melanophris , currently listed by the IUCN as a species of Least Concern (BirdLife International, 2018b; BirdLife International, 2023) and although listed as Threatened in Argentina (MAyDS y AA [Ministerio de Ambiente y Desarrollo Sustentable y Aves Argentina], 2017).…”

Seabirds, particularly albatrosses, are among the most threatened birds as a result of their continuous exposure to anthropic pressures including interaction with commercial fisheries, climate change and pollution. Several studies that have focused on the spatial distribution of foraging seabirds have identified a certain level of segregation between age classes. The black‐browed albatross Thalassarche melanophris is the most abundant albatross species in the South‐west Atlantic Ocean and the main pelagic seabird interacting with a range of fishing fleets. There is a considerable lack of knowledge about the biology of immature individuals and on habitat suitability of the species during non‐breeding season (winter). The aim of this study was to assess the foraging habitat suitability of the black‐browed albatross in the South‐west Atlantic during the austral winter, analysing differences between adults and immatures individuals. Habitat suitability models were based on foraging locations recorded by 15 satellite transmitters deployed on six adults and nine immature individuals between 2011 and 2015. Remotely sensed oceanographic data were used to characterize suitable foraging habitat for the albatrosses. Differences were found in foraging habitat suitability by age class, with adult selecting areas located in deeper waters over the continental shelf break as well as in neritic zones under cooler water temperatures, whereas immature individuals foraged chiefly off coastal waters having more moderate temperatures. Knowing habitat suitability and segregation patterns within‐species is key for the conservation of critical marine habitats given that, by only considering one age class, other important habitats would be neglected and not considered in conservation efforts to mitigate threats such as incidental mortality. It is important to include all age classes when studying patterns of associations with threats, such as fishing activity as a proxy of risk of bycatch, and for the development of Marine Protected Areas.
