My new office is on the top (4th) floor of a building which is taller than other structures in the vicinity. I have lovely big windows, and have seen gulls and crows flying nearby. Yesterday a hummingbird was the height of the windows. There are trees lower than the building. I?m about to have UV blocking film installed, so this would be the time to add some decals (the ceilings are 16?).The installer said that the uppermost windows will be reflective, so that the bird can see itself. - I?d appreciate suggestions as to type and placement. thanks in advance, Marla Herbig
