Sensor Arrays for Acoustic Monitoring of Bird Behavior and Diversity

该合同支持鲁棒和适应性传感器阵列以及相关软件的开发，用于观察和分析鸟类的多样性和行为。选择鸟类作为这项工作的测试组，是因为它们在生物多样性中的重要性，并且因为它们在将要探索的特性（即鸟类发声）方面具有很好的特征。该项目将利用加州大学洛杉矶分校嵌入式传感中心（CENS）开发的现有传感器阵列。这项工作将在加州大学洛杉矶分校的实验室和几个实地地点进行：(1)加州大学河滨分校詹姆斯保护区，靠近加利福尼亚州的爱德怀尔德，这是一个配备了大量仪器的实地地点，有全职的传感器阵列专家。在这里，方法将首先进行测试，然后部署到(2)加利福尼亚州蒙特雷附近的黑斯廷斯保护区，在那里对橡子啄木鸟进行了标记和研究。传感器阵列将用于识别单个啄木鸟，定位它们，并识别它们的行为模式，这些模式与它们使用的大约10种叫声有关。阵列也将部署在墨西哥恰帕斯州的蒙特斯阿苏雷斯生物多样性保护区，该保护区在热带雨林中拥有丰富的鸟类物种多样性。在这里，将开发传感器阵列来识别和定位该地区不同的鸟类。该项目开发的传感器阵列、软件和方法将满足测定生态系统生物多样性的迫切需要。远程感知、记录和自动分析声学行为所需的工具将对生态学、生物多样性和行为的研究大有帮助。

This award supports the development of robust and adaptable sensor arrays and related software for observing and analyzing bird diversity and behavior. Birds have been selected as the test group for this work because of their importance in biodiversity, and because they are well-characterized with regard to the properties that will be explored (i.e. bird vocalizations). This project will make use of existing sensor arrays developed by the UCLA Center for Embedded Sensing (CENS).The work will be performed in laboratories at UCLA and at several field sites: (1) the UCRiverside James Reserve, near Idyllwild, CA. - a heavily instrumented field site with full-time specialists on sensor arrays. Here, methods will be initially tested, then deployed to either (2) the Hastings Reserve, near Monterey CA, where acorn woodpeckers have been marked and studied. The sensor arrays will be used to identify individual woodpeckers, locate them, and to identify patterns in their behavior associated with the approximately 10 calls they employ. Arrays will also be deployed to (3) the Montes Azules Biodiversity Reserve in Chiapas, Mexico, which has a rich diversity of bird species in a tropical rainforest. Here, the sensor arrays will be developed to identify and locate different bird species in the region. The sensor arrays, software, and methodology developed by this project will serve a severe need to assay biodiversity in ecosystems. The tools needed to remotely sense, record and automatically analyze acoustical behavior will be enormously helpful for studies of ecology, biodiversity and behavior.
