Day 8.227: Two birds at the window

Two approaches to life as exemplified by birds I have seen near windows in the last couple of weeks.

Male ruby-throated hummingbird - come close to the window in order to eat free food. Result - eat well and never touch the window.

Male American goldfinch - land on the windowsill and then, for no apparent reason repeatedly try to fly through the glass. Result - fail (better than the alternative).
