And now, the Lawrence crow roost is a test case for government-funded research on new 3D imaging technology. Here's my @gbhnews video, audio and print stories about this crazy scene: https://www.wgbh.org/news/local/2024-03-27/thousands-of-crows-in-lawrence-are-a-marvel-of-nature-and-test-case-for-new-imaging-technology
