The toucan sample response eloquently discusses the function of the toucan bill. However, the speaker questioned the author's point of view for three reasons: first, in reading the article, the bill can serve as a weapon against predators. The professor said that although it looks like a weapon, the bill is too fragile.
In addition, in order to protect birds, the heavy weight of bulls changes the flight of birds The second difference between the speaker and the author is that the color and shape of the beak can confuse potential predators. He said that this bird always likes to sing, and it doesn't want to confuse potential predators. This is in direct contradiction with the article.
Finally, the professor disagrees with the view in the reading materials that beaks are so large that they can help the body cool down. On the other hand, feathers can keep body temperature. He pointed out that for other birds without beaks, they can also control their body temperature.
What can the toucan do to keep warm when the temperature drops at night is completely contrary to the author's expectation Chi.
