The aim of this study was to evaluate images captured using a drone to determine the presence of estrus detection adhesives in bovine females. 56 healthy, reproductive age and extensively reared cows were used. An adhesive was attached to each female in the region of the caudal insertion to detect estrus. The animals were divided into seven experimental groups (n=8), as follows: Group 1 (control) - females without adhesive; Group 2 - females with adhesive without any scraping area (100% gray); Group 3 - females with dark rump coat with 50% green shaving adhesive; Group 4 - females with dark rump coat with 50% orange shaving adhesive; Group 5 - females with pale rump coat with 50% green shaving adhesive; Group 6 - females with pale rump coat with 50% orange peel adhesive; Group 7 - females with dark rump coat with 25% orange shaving adhesive. The presence, color and degree of scraping of the adhesive were analyzed according to the influence of flight time and height, coat color and the presence or absence of clouds at the time of image capture. Data were submitted to analysis of variance and means to Tukey's test, at 5% significance. There was a statistical difference for the color of the sticker in relation to flight time and coat color (P<0.05), and the flight performed in the late morning and the animals with dark-haired rump showed the best results. The analysis of photographs obtained using a drone showed reliable applicability in bovine females.
