In some bird species, some populations migrate while others are sedentary. Major factors affecting the type of strategy adopted (migrating or staying put) involve the relative costs and benefits associated with each strategy. Briefly explain why this is the case; you should outline the benefits of migrating and the costs, and then explain how these affect the strategy adopted for a particular population

Step 1
For instance, birds often migrate to warmer climates during winter months where food is more readily available. This can increase their survival rate and reproductive success. On the other hand, migration also has its costs. It requires a significant amount of Show more…

Domesticated animals, such as house cats, may disturb ecosystems. Are outdoor cats a density-independent or density-dependent factor limiting the populations of birds? Explain your answer. Then, brainstorm as many ways as you can think of for how home bird feeders might raise or lower bird population sizes.
