Abstract: Geophagy is a habit recorded for parrots, which seek earthy or soil-like substances presumably to help them in digestive functions, whether mechanical or chemical ones. Few studies are devoted to this feeding peculiarity in the Pantanal region. Here are reported two events of geophagy, for the Blue-and-yellow Macaw (Ara ararauna) and the Nanday Parakeet (Aratinga nenday) in the Pantanal subregions of the Miranda-Abobral and Nhecolândia, Mato Grosso do Sul, respectively. Keywords: geophagy, Pantanal, psittacine… Show more

“…Despite its elegance and broad appeal, recent studies have found little support for the toxin-protection theory (Lee et al 2009). However, the studies undertaken to date have not been able definitively to rule out toxin protection as a possible explanation for geophagy (Brightsmith et al 2008) and the theory is commonly invoked in scientific and popular discussions of geophagy for a broad array of taxa from across the globe (Severo-Neto 2012, Costa-Pereira et al 2015, Angier 2016, Bradbury & Balsby 2016.…”

“…In birds, geophagy has been widely reported in families such as Psittacidae (Diamond et al 1999, Brigthsmith & Muñoz-Najar 2004, Severo-Neto 2012, Costa-Pereira et al 2015, Dornas et al 2016 and Columbidae (Brigthsmith & Muñoz-Najar 2004, Symes et al 2005, Downs 2006), but not as much for other families, such as Cracidae (Brigthsmith & Muñoz-Najar 2004), Corvidae (Diamond et al 1999) and others (see also Gionfriddo & Best 1999). For the family Corvidae (Aves: Passeriformes), which includes 130 species distributed worldwide (dos Anjos & Bonan 2019), records of soil ingestion are particularly scarce and scattered in the literature.…”
