Unmanned aerial vehicles (UAVs) have become a popular wildlife survey tool.Most research has focused on detecting wildlife using UAVs with less known about behavioral responses.We compared the behavioral responses of breeding blue-winged teal (Spatula discors) (n = 151) and northern shovelers (Spatula clypeata) (n = 46) on wetlands flown over with
Loss of natural wetlands is a global phenomenon that has severe consequences for waterbird populations and their associated ecosystem services.Although agroecosystems can reduce the impact of natural habitat loss, drivers of use of such artificial habitats by Cover Sets waterbirds remain poorly understood.Using the cosmopolitan northern pintail Ana
This work presents the design of a compact dual-port circularly polarized antenna based on the new coupler topology.The antenna can radiate a right-hand circular polarization (RHCP) in two opposite directions depending on the COMBO input port.In the proposed structure, the radiating system has three inverted F antennas connected to a 120° hy
