“…With subtle differences in the consumpAon of plant species, possibly related to the availability of food resources, the diet of the Blue-and-yellow Macaw was widely based on fruits and seeds, as reported in other studies in both natural and urban areas (Tubelis 2009, Santos & Ragusa-Ne'o 2014, Barros & Purificação 2020. Therefore, the consumpAon of several species of fruits and their seeds, as revealed by the values of niche breadth index, reinforces the generalist feeding habits of this species (Gale‰ 1997, Lee et al 2014, Santos & Ragusa-Ne'o 2014, Barros and Purificação 2020.…”

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.

“…Macaws (genus Ara) are colorful and majestic birds found in the country's tropical forests, known for their role in spreading seeds of various palm species. By feeding on the fruits of these palms and then flying to other areas, macaws contribute to the dispersal of these seeds, which are essential for maintaining biodiversity Purificação, 2020).…”

Heatwaves, defined as prolonged periods of excessive heat, are becoming more frequent and severe due to global climate change. These extreme heat events can have significant impacts on ecosystems and wildlife, particularly on avian fauna. Birds, as vital components of ecosystems, are highly susceptible to the adverse effects of heatwaves. Impacts directly attributable to adverse weather and changing climate regimes include a higher risk of mortality, reduced breeding success, compromised body condition and immunocompetence, declining populations, range changes, and potentially maladaptive behavioral adjustments in foraging, parental care, and migration. This vulnerability is exacerbated by the loss and degradation of their natural habitats, which hinders their ability to adapt to constantly changing climatic conditions. Understanding the vulnerability of bird populations during heatwaves is essential for devising effective conservation strategies. Conservation efforts should focus on preserving and restoring critical bird habitats, providing access to freshwater sources, and creating artificial shelters. Additionally, public education plays a significant role in raising awareness about the importance of bird conservation during heatwave events and in the broader context of climate change. In analyzing the subject, the study aims to provide more precise information to support the public decisions to be made, as well as to guide awareness for the implementation of conservation actions.
