There is a growing body of research indicating that drones can disturb ***,it is usu-ally unclear whether the disturbance is due to visual or auditory ***,we examined the effect of drone flights on the behavior of great dusky swifts Cypseloides senex and white collared swifts Streptoprocne zonaris in 2 breeding sites where drone noise was obscured by environmental noise from waterfalls and any disturbance must be largely *** performed 12 experimental flights with a multirotor drone at different vertical,horizontal,and diagonal distances from the *** all flights,17%causedporarily a bandon the breeding site,50%caused half to abandon,and 33%caused more than half to *** found that the diagonal distance explained 98.9%of the variability of the disturbance percentage and while at distances>50 m the disturbance percentage does not exceed 20%,atpercentage increase to>60%.We recommend that flights with a multirotor drone during the breeding period should be con-ducted at a distance of>50 m and that recreational flights should be discouraged or conducted at larger distances(e.g.100 m)in nesting birds areas such as waterfalls,canyons,and caves.

Drones are increasingly used for fauna monitoring and wildlife tracking;however,their application for wildlife tracking is restricted by developing such *** we explore the potential of drones for wildlife tracking using an off-the-shelf system that is easy to use by non-specialists consisting of a multirotor drone,smartphones,and commercial tracking devices via Bluetooth and Ultra-Wide Band(UWB).We present the system configuration,explore the operational parameters that can affect detection capabilities,and test the effectiveness of the system for locating targets by simulating target animals in savanna and forest *** self-contained tracking system was built without hardware or software *** 40 tracking flights carried out in the Brazilian Cerrado,we obtained a detection rate of 90%in savanna and 40%in forest *** for targets in movement(N=20),the detection rates were 90%in the savanna and 30%in the forest *** spatial accuracy obtained by the system was 14.61 m,being significantly more accurate in savanna(x=10.53)than in forest areas(x=13.06).This approach to wildlife tracking facilitates the use of drones by non-specialists at an affordable cost for conservation projects with limited *** reduced size of the tags,the long battery life,and the iower cost compared to GpS-tags open up a range of opportunities for animal tracking.
