Usually, when we see birds, there are only a few flying together at the same time. When large flocks appear, the effect can be magical, as well as a little unnerving. Birds are interesting animals. Those that fly in flocks tend to do so for a few reasons. Foraging, protection, mating, raising families, warmth and aerodynamics are just some of the benefits that birds get by staying close together. Another interesting bit about flocks is that different kinds of birds go by different names. Have you ever heard of a charm of finches, a raft of ducks, a horde of ravens, a gaggle of geese or a gobble of turkeys? Watch now to see if you can tell what kinds of birds swoop in to take over this tree.
