When you suspect someone is trying to break into your house, the last thing you would expect to see is a hawk fighting… himself!

While the bird makes a concerted effort to defend his territory on the outside, the window between him and the house proves a worthy opponent. See him pounce off the glass a number of times before giving in, if only temporarily. Credit: YouTube/Jordan Zacher
