Bird predation on Roseau cane scale as revealed by a web image search and querying a citizen monitoring database

An invasion of Roseau cane scale, Nipponaclerda biwakoensis, native to East Asia, is associated with recent widespread dieback of common reed stands in the Mississippi River Delta, Louisiana. A previous study suggested that, in its native range, the combined mortality from Common Reed Bunting Emberiza schoeniclus and parasitoid wasps may control the abundance of Roseau cane scale. However, there is limited knowledge about which other bird species may prey on Roseau cane scale or the feeding patterns of these birds. Here, we used web search and citizen science monitoring data to tabulate bird predation events on Roseau cane scales across sites in Japan and determine which bird species may be the most important predators and when the observed feeding typically occurs. We scanned web entries using both Google image searches and the social networking services, including Twitter, Instagram, and Facebook. Additionally, we accessed long-term field observation records obtained by volunteer moni..., , , , This Noriyuki_2023_README.txt file was generated on 2025-08-15 by Suzuki Noriyuki
