The activities performed followed closely those described in the project proposal. Out of the specific aims, i, iii and vi were fully achieved (more comprehensively than described in the proposal). Namely, we tailored the innovative mobile phone citizen science application (Research for JYU Mobile) to audio-based bird monitoring, and published the "Muuttolintujen kevät" (spring of migratory birds) phone app, currently available in app stores for Finnish users. The phone app submits the raw audio to computational backend that uses convolutional neural networks for automated species classification from the audio data; the model we have developed performs much better than e.g. BirdNet and is well calibrated to these data. We have run the citizen science campaign in close collaboration with the Finnish Broadcasting company YLE, which approach has attracted a very large number of users (270,000 users; ca. 5% of the Finnis population) who have submitted >20M bird vocalizations. To integrate the citizen science approach to professional research, we have implemented permanent point count routes into two Finnish cities (Helsinki and Jyväskylä) as well to ten Finnish National Parks. Citizens have performed in these pre-selected locations >10,000 standardized 5-minute point counts with their smart phones. All raw audio is stored, enabling rigorous validation and reuse of the data. Out of the specific aims, ii, iv and v were partially achieved. Namely, while we have implemented high-performance computing workflows of joint species distribution modelling to enable essentially real-time flow of information from user recording to biomonitoring outputs, these workflows are currently implemented only as beta-versions and they will be finalized and published in future work. As these developments have taken more time than we expected, we were not able to utilize them in in hyperautomation to incorporate citizen scientists in Bayesian adaptive design. We have however provided the citizens encouraging feedback through the app. This has been successful, as evidenced by our large and committed userbase.
