#630 Evaluating the relative effectiveness of patterns on glass as deterrents of bird collisions with glass - ScienceDirect 30.9.2020

https://www.sciencedirect.com/science/article/pii/S2351989419303579#bib29

"There is a great deal of interest in UV patterns for walls and windows, because humans do not see UV wavelengths, possibly permitting effective collision solutions visible only to birds. It should be kept in mind, however, that 1) there is very little, if any, UV in the early morning or on days with low UV indexes and 2) many bird taxa cannot see UV wavelengths."
