Our windows are coated with highly-reflective solar film which, in daytime,
makes them act (as viewed from the outside) as one-way mirrors. Yesterday
morning whilst my wife and I were standing at the kitchen sink doing the
washing-up, a Red Wattlebird came and perched on the window sill and held a
long interrogation of its reflection, alternately calling and cocking its
head sideways whilst closely peering at its reflection. This lasted for
about three minutes, affording us an excellent close-up view.
I have not seen any other incidents of birds being attracted to our windows
in this way.
Would the use of one-way glass (or mirrors) be a good technique for
constructing observation hides?
