Energy-efficient battery, solar panel or mains supply powered bird feeder intended for outdoor conditions incorporates a capacitive sensor, which, upon capacitance change, registers and counts bird visits and takes photos and video clips. The capturing frequency can be changed via software located in the server or mobile application. The bird feeder includes a real-time clock, a temperature sensor for measuring outside temperature and a feed checking sensor. The electronic components of the bird feeder are located in a watertight enclosure. The bird feeder is connected to the Internet using wireless data communication and all feeders are globally connected to the central Internet server. The bird species identification is accomplished using the camera and the controller, located in the bird feeder, and software, located in the internet server. The topology of the electronic circuitry and software is also suitable for identification, registration and counting of other living organisms.
