In our previous post we showed maps of four territorial birds, and an apparently non-territorial bird. The map below illustrates again how the behaviour of territorial birds differs from that of an apparently non-territorial "floating" bird. At this time of year, territorial breeding vultures will be defending their territories against intruders, conducting courtship and producing eggs and young. Of course, they still have to feed. Floating birds don't have the burden (or benefit) of holding a territory, so they wander. Those wanderings may include dwelling in some places for some limited amount of time, but they really are not tied to any locations.
