There’s also a project you can add these observations to: Bird-window collisions
I normally add collision observations to the project but I wouldn’t annotate as a track, as it doesn’t seem to quite fit the situation.
I don’t know which decals you got, but (and this is as much for anyone else reading the thread, as you may know this) the ones that look like birds of prey are not effective, unless you put so many as to leave no more than 10 cm between each one. American Bird Conservancy has more information on effective and simple methods to prevent collisions here. I’ve installed the white vinyl dots and have had no fatal collisions on those windows since installing them.
