1. Before starting, think about the different types of beaks and how they might influence the calories that birds need to survive and to reproduce.
Which bird beak is most likely to survive? ______large________ Which bird beak is most likely to reproduce? ___large___________
2. Select one type of beak from the four types that you have. Spend 5 minutes or so and practice picking up different food items with your beak.
3. If possible, enlist the help of another person to act as the timekeeper. When the signal is given, you have 15 seconds to put as many of one type of food item as possible into the bird’s stomach. You can only put in one food item at a time and you can only use one hand to maneuver the bird beak.
4. After feeding, count the number of food items for your beak type and record that data in Table 1.
5. Repeat the feeding using your same beak with each of the different food types. Then switch to another beak type and repeat all of the feeding experiments.
TABLE 1: Feeding Data
6. Use your data from Table 1 to fill in the needed information and calculations in Table 2. TABLE 2: Data Analysis

1. Before watching the video, you will be assigned two of the following groups of animals to summarize presented information.

all tie together. Competition allows only the most fit species to pass on their genes. In the bird beak lab, the chopsticks were unsuccessful at picking up seeds while the tweezers were successful and would survive over the chopsticks and pass on their traits. Competing with other organisms for a desired food or object can cause the less fit to die off and not pass on genes. During the bunny lab, another example, the long teeth bunnies survived longer over the short teeth bunnies. This occured due…
