Deers will randomly charge through a window/glass pane (sometimes a house, sometimes at a mall, sometimes at a store) and I have no clue whyIn: Biology ShareFacebook 2 AnswersVoted fishnchips17 Added an answer on October 7, 2019 at 4:27 pm The simple answer would be, they cannot see the glass, have never experienced glass and thus don’t think there is a barrier before them.0Reply Share ShareShare on FacebookShare on TwitterShare on LinkedInShare on WhatsApp Gnonthgol Added an answer on October 7, 2019 at 4:52 pm A clean pane of glass is transparent and therefore very indistinguishable from empty air. You even see people walk streight into glass doors from time to time. There is a couple of things making this more common for deers. Firstly a deer in an urban environment is often very scared and wants to flee the situation. And while running full speed in a panic it can be hard to notice a glass pane. Secondly deer and a lot of other herbivores have very bad depth perception due to how their eyes are located. This means that they are unable to notice how far away the dust and grime on the glass is and can interpret it as being further away then it really it.0Reply Share ShareShare on FacebookShare on TwitterShare on LinkedInShare on WhatsAppLeave an answerLeave an answerCancel reply Attachment Select file Browse Featured image Select file Browse What is the capital of UK?
