The goal of this project is to develop, test, and deploy novel sensors that will enable the study of activity and migration of small songbirds (20-50 grams). The sensors required for such small animals require weight and energy budgets (1 gram and 1 micro Watt, respectively) below most low-energy devices and must survive in challenging environments and collect useful data over many months. This project has the potential to significantly impact the science of animal behavior because many important species cannot be effectively monitored with existing technologies -- for example roughly half of bird species weigh less than 50 grams.While the focus of this project is to develop the technologies that will enable other researchers to study the behavior of small animals, the project will test these devices on a specific model species (Dark-eyed Juncos) in order to enhance the understanding of the variation of timing on reproduction, migration, and biodiversity. Finally, while the target application for this project is animal biology, many of the fundamental technical problems are common to general low-energy sensing problems. For example, a key problem is detecting the onset of interesting events using extremely low energy levels prior to expending the significantly higher levels of energy needed to collect high resolution data.

该项目的目标是开发、测试和部署新型传感器，以研究小型鸣禽（20-50克）的活动和迁移。 这些小动物所需的传感器需要的重量和能量预算（分别为1克和1微瓦）低于大多数低能量设备，并且必须在具有挑战性的环境中生存，并在数月内收集有用的数据。 该项目有可能对动物行为科学产生重大影响，因为现有技术无法有效监测许多重要物种-例如，大约一半的鸟类体重不到50克。虽然该项目的重点是开发技术，使其他研究人员能够研究小动物的行为，该项目将在一个特定的模式物种（黑眼容科斯）上测试这些设备，以提高对繁殖、迁移和生物多样性时间变化的理解。最后，虽然该项目的目标应用是动物生物学，但许多基本技术问题与一般低能传感问题相同。 例如，一个关键问题是在花费收集高分辨率数据所需的显著更高水平的能量之前，使用极低的能量水平检测感兴趣事件的开始。
