Wow never seen, stunning thanks for sharing. A Freind & I rescue songbirds (mostly Warblers) that hit the glass skyscrapers in Newark NJ, TRT made a video named 'Window Strikes in the Business District' of us picking up injured Warblers. In Newark most of the birds that hit the glass skyscrapers perish on impact, or when fall to the cement pavement. The injured get a 2nd chance when we bring then to TRT. Newark is on the Atlantic Flyway
