Hi, did you enjoy my article about the red-crowned cranes last month?

Well, last night I discovered some of the notes I took on the DMZ when I went to observe the cranes. It contained additional information that I did not present on my articles and I would love to share it with you guys.  Well, what kind of habitats do the cranes prefer?

First, open space. In the last article, I mentioned how the cranes cannot escape as fast as other birds. The red-crowned cranes are the second largest bird in the world. In other words, they cannot launch the moment they flap their wings. They have to make an approach run (a small run before you launch) to create a lifting force. 

Second, mountains. It is not easy to be alert all the time. However, if there is a mountain behind, the cranes only have to watch out their front. In other words, they only need to lookout one side of their view. It is unlikely that a predator would come down from the mountains to approach them. 

Third, reeds. Cranes don't want to be seen and reeds provide a hideout for these cranes. They are more comfortable inside the reeds. 

Fourth wetlands. Wetlands have a sound ecosystem of reptiles and amphibians. When the cranes stop to the DMZ to go further south, they search for food with high calories such as fish, frogs and mussels, because they have another several thousand miles to fly. One interesting thing to know?.how to they drink water during their flight? I mean you can stay without food but you must drink water! Cranes gain water from the water stored within their bodies.

Now, what are some factors that hinder the cranes from hibernating?

Electrical lines obstruct the cranes from flying. Embankments sever the ecosystem between the wetland and the inland. Sediments which create mudflats cannot accumulate endangering many aquatic species. Also the cranes cannot find place to stand to search for food. If embankments have to be made, they must be made into steps so it would at least allow the movement of animals in and out of the wetlands .
