There has always been a housing shortage in Amsterdam, for as long as I can remember (ok, I have only been here for 9 years so at least 9 years). Now it seems even the birds are having problems finding places to build their houses.
Bird house cluster communities like this one will soon be popping up all over the city. This one in particular has a canal view and the old lady on the first floor no longer has to go down to the canal to throw her bread to the birds. She just opens her window and hand feds them, one-by-one! Wait I think I see a bird just peeking into her window.
