Have you ever wondered how birds know when it\u2019s time to fly south for the winter? It\u2019s not like they count down the days on their mini bird calendars. There must be something else that tells them when it\u2019s time to hit the road\u2026er\u2026sky. There is, and you\u2019re about to find out!<\/p>\n\n\n\n

As the weather turns colder, it can get pretty hard to find food. You don\u2019t exactly see many fruits growing or insects crawling when there\u2019s snow on the ground. As food disappears, many birds know it\u2019s time to say \u201csee you later\u201d and head down south. But when they leave depends on what they eat.<\/p>\n\n\n\n

Birds that eat insects (insectivores) start their migration in late August or early September. That\u2019s exactly when we start to see fewer insects around. Birds that eat fruit, seeds, and insects (omnivores) stick around longer. They might leave as late as November!<\/p>\n\n\n\n

Is it getting dark out or is it just me?<\/strong><\/h3>\n\n\n

Another way birds know that it\u2019s time to leave is by paying attention to the length of the day. You know how it gets darker earlier in the winter? Birds notice it too. The darkness is a cue for birds that it\u2019s time to head out.<\/p>\n\n\n\n

Sometimes they just know<\/strong><\/h3>\n\n\n

Migratory birds go through something called zugunruhe. No, that wasn\u2019t a sneeze. Zugunruhe is a German word that scientists use to describe a restlessness birds get when it\u2019s time to migrate. Even migratory birds kept as pets go through this. Bird owners might see their birds fluttering and being more active in the spring and fall.<\/p>\n\n\n\n

There you have it! You can forget the calendar because birds don\u2019t need it! They have lots of tools that tell them when it\u2019s time to leave.<\/strong><\/h3>\n","protected":false},"excerpt":{"rendered":"
