26. European starlings are birds that take over the nests of other birds. When they move into an area, starlings reproduce quickly. Taking over the nests of other birds most likely increases the number of starlings by helping them to do what? A attract a better mate B. compete for resources C. migrate during the winter D. blend in with the environment

To solve this problem, we need to analyze the options provided and determine which one best explains how taking over the nests of other birds helps European starlings increase their population. 1. **Attract a better mate (A)**: While having a secure nesting site can be attractive to potential mates, the primary benefit of taking over nests is not directly related to mate attraction. 2. **Compete for resources (B)**: By taking over the nests of other birds, starlings gain access to established nesting sites, which can lead to better survival rates for their young and increased reproductive success. This directly relates to competition for resources, as they can utilize the nests and possibly the surrounding area more effectively. 3. **Migrate during the winter (C)**: Nesting behavior is not directly related to migration. Starlings may migrate regardless of their nesting situation. 4. **Blend in with the environment (D)**: While blending in can be beneficial for survival, taking over nests does not directly contribute to this ability. Based on this analysis, the most logical answer is: **B. compete for resources** Taking over the nests of other birds allows starlings to secure better nesting sites, which enhances their ability to reproduce and thrive in a given area.
