This can happen anywhere there are houses and birds. This story is about what to do when a bird flies into your house or apartment in Cambridge. Which can happen to anyone. Here, in Cambridge, measuring just about seven square miles, with so much wildlife, so many birds, especially at this time of year. There are also so many bird nests (where many birds live), you probably live within fifteen feet of a bird nest nestled into some eaves or foyer and you don’t even know it.
