    Birds play a crucial role in maintaining the balance and health of ecosystems worldwide, with their significance extending from ecological functions to cultural symbolism. Ecologically, birds contribute to pest control by preying on insects, regulating populations, and mitigating agricultural damage. They also aid in seed dispersal and pollination, facilitating vegetation growth and plant reproduction. Furthermore, birds serve as environmental indicators, reflecting broader ecological shifts. Recently, the National Ecological Observation Network (NEON) has undertaken the task of monitoring bird populations across various U.S. ecosystems. The project aims to decipher bird abundance patterns during peak growing seasons, synthesizing data on variables such as bird counts, beetle populations, latitude, longitude, tree dimensions, and vegetation productivity during 2017-2022 sourced from NEON databases. The findings reveal that bird counts decrease from low to high latitudes, with both beetles and vegetation productivity positively influencing bird abundance, while tree breast height diameter shows weak correlation. Strong inter-annual variations in bird counts were observed nationwide. Both correlation analysis and structural equation modeling underscore vegetation's pivotal role in bird abundance. In essence, the developed bird count data system offers valuable insights into bird and ecosystem health, aiding communities in understanding and preserving these vital ecosystems.
