We aimed to analyze the food resources consumed by Ara ararauna (Linnaeus, 1758) in the urban area of Campo Grande, from the photographic records released on the WikiAves© platform by the professional and amateur photographers. We retrieved 36 records of A. ararauna feeding, while we identified 16 species of plants in the diet of A. ararauna. Fruits and seeds were the most consumed plant parts, and 75% of the species diet was composed of native plants. As there is no prior information available on the diet of this species in the urban area of Campo Grande, the records released on the WikiAves© platform helped us to answer several important questions regarding its feeding habits. We highlight the importance of planting native species in urban afforestation, as well as the maintenance of urban parks and green areas, to maintain the populations of A. ararauna in the city.

Electrocution is a theme that has been rarely reported for large macaws. The objective of this study was to analyze mortality of macaws due to electrocution in an urban area of Campo Grande, Mato Grosso do Sul. Between 2011 and 2020, 59 macaws were registered as having died through electrocution, and these were from two species: Ara ararauna (Linnaeus, 1758) and Ara chloropterus (Gray, 1859). A. ararauna had the largest number of deaths registered (48), and A. chloropterus had 11 individuals. Electrocution was shown to be an important factor for the loss of large macaws in this urban environment. Body size, wingspan, and behavior of the macaws, as well as location and proximity of food resources and nests to electrical structures, were shown to increase the probability of electrocution. These results demonstrate the need to develop mitigation measures to reconcile the sustainable development of a medium-sized city such as Campo Grande with biodiversity conservation.
