Do you know what are these grebes doing? If you are a bird watcher you may have been lucky enough to watch the spring courtship display of Great Crested Grebes. The birds face each other and shake their heads in opposite directions, or they may dive and surface with weed in their beaks, rear up breast to breast and sway from side to side. These displays are very exciting to watch.
Both male and female grebes have strikingly colored plumes and ear tufts which emphasize the head movements. The Great Crested Grebe is a water bird, of course, and you can often see it in gravel pits, reservoirs, and large lakes. It is in its element in the water and rarely leaves it, building a nest of floating vegetation in which to lay the eggs.
The nest is abandoned as soon as the eggs hatch and the young grebes climb onto the backs of the parents for journeys around the lake. They are been carried underwater when the parent bird dives for food, although sometimes they are dislodged and can be seen to bob up to the surface, none the worse for the experience.
Why are albatrosses ringed?
This man is carefully placing a metal ring or band on the leg of an albatross. Many species are ringed in this way by bird organizations in order to study bird movement. Many birds’ migrate-albatrosses travel enormous distances and much is learned about this phenomenon by analysis of the information the recovery of the rings provides.
The rings are stamped with the name of the organization carrying out the research, and numbers which indicate the place of ringing, the date, and other relevant information. If you ever find a bird with a ring, send the ring to the appropriate people, for you will be helping them to carry out their valuable work.
