Coragyps atratus is a New World vulture species from the Order Cathartiformes. This species benefits from human activities, especially the improper disposal of organic waste, which increases food supply. The proximity of C. atratus with urban areas can lead to various problems, such as the risk of collision between these birds and aircrafts because of their mass and flight pattern, causing millionaire losses as well as serious consequences to society. This study aims to understand and analyze ecological and biological aspects of the population of C. atratus on Fontes do Ipiranga State Park (PEFI) in order to generate data that supports decision making regarding the management of this species within the park. Searches for identification and mapping of rest areas, feeding grounds and nesting were held on PEFI. To monitor the concentration of animals in the park and understand which climate variables influence it, these animals counts were performed on three different times of the day (morning, noon and evening) over five months. Statistical analysis of these data led to the conclusion that the period of data collection and humidity are variables that significantly influence the amount of animals sighted in the study area. The concentration of C. atratus on PEFI is highest during the afternoon, when the temperature is higher and the percentage of moisture in the air is lower.
