The purpose of this project is to provide a foraging puzzle that will measure the force produced by the red crossbill (Loxia curvirostra) while it forages for seed. The force produced will be then examined to determine different feeding behaviors in risk-reward scenarios and how willing they are to work for food. The physical device will hang from the side of a cage and apply a variable force to a hinge that the birds will open for seeds. When opening the hinge, a sensor will record the amount of force exerted by the birds, and send this data wirelessly to an online database, where it will then be output as a graph of force vs time. While the system built fulfills the main purpose of the project; to measure and record data on force applied by a bird; ideally, 30 - 40 individual systems with differing resistive forces would be used to study behavior. Our system currently is designed to be used individually, as it requires its own microcontroller and power supply. To adapt our system for mass use, rather than each system using its own microcontroller, the system could be designed to easily attach to a main microcontroller and power supply, that allows for multiple sources of force data.
