　　关于鸟类如何自我调节准备移民The lecture talks about how birds make self-adjustment to prepare for migration.

　　1)First, some birds may experience physical change. For example, to prepare for long distance flight, migrating birds have to store sufficient amount of energy to sustain their flight and to reduce the times they have to stop over for rest. So they would eat a lot more than they usually do to reserve energy in the form of body fat.

　　2)The second adaptation is behavioral change. During migration journeys, some birds that usually live on their own begin to act more socially. They form into a group with other birds so they can protect better themselves as a whole from predators."

　　两种影响大多数发生在个体的行为受群体思维的改变。Two types of majority influence happen when an individual’s behavior is affected and altered by group thoughts.

The rest of the people in the car think that you should go straight while you want to make a left or right turn. Because the majority wants you to go straight, you will change your original idea. Type 2: normative influence where people want to be accepted by the group or try to fit in. For instance, you are going to a movie with some people that you want to be friends with. After the movie, although you think the movie is awful, the rest of the people think the movie is great, you will also agree with them. Because you want to fit in, to get along

　　一些鸟类如何在泥泞的地方觅食In the lecture the professor talks about two physical adaptations of wading birds, which allow them to walk through mud near shallow wagers while searching for food. One is their sensitive beaks. The other is special feet with web connecting toes. The professor uses the example of storks to show how these two features help wading birds acquire food in muddy places. First, the beaks of storks are long and have sensors. With these sensors, storks can sweep their beaks mud and quickly sense if an object is a food source or not. This allows them to feed themselves efficiently. Second, wading birds’ feet can prevent themselves from sinking the mud. For example, storks have long and big toes, which spread the bird’s weight over the surface. These toes can help the birds keep their balance while they are walking on a muddy surface.
