ResumoFleeing from predators might save individual's life, however, being vigilant or fleeing consumes time, energy and decreases chances for feeding, mating, and protecting the nest.Thus, escaping preferentially occurs when the costs of fleeing is higher than remaining (Blumstein 2006, Cooper & Frederick 2007, Bateman & Fleming 2011).Additionally, there is a trade-off between foraging and being vigilant, influencing the decision-making process of staying or fleeing.This trade-off directly influences an animal's decision to remain and/or establish itself in different locations (Bateman & Fleming 2011).For example, in urban environments, the number of pedestrians reduced bird's abundance, and remaining individuals increased vigilance, reducing foraging, being this effect more intense in large animals (Fernández-Juricic et al. 2002).However, other factors may favor the individual's decision to flee, such as a menacing predator and the lack of shelter, contributing for the complex interactions leading to the fleeing decision (Price 2008, Dowling & Bonier 2018).Here we evaluated, within an urban landscape, the influence of environmental suitability in the flight distance relative to possible predators.
