Lesson 2: Why does the songbird sing??

Topic: Bird Songs vs Calls Theme: A bird species’ song and calls have different characteristics and serve different purposes to enhance survival and reproduction.

Lesson 3: Wait… birds have dance battles??

Topic: Courtship Rituals and Mating Displays Theme: The courtship rituals and mating displays of birds are not only entertaining, but also teach us how natural selection can produce unique behaviors and physical features.

Lesson 4: How does one make a nest??

Topic: Bird Nesting and the Nest Cycle Themes: Nests are important structures for young survival. Nest types and materials vary widely depending on species and habitat.

Lesson 5: How is reproductive success measured??

Topic: MRBO Nest Monitoring Project Themes: One way we can measure reproductive success is by measuring nesting success. We can use long-term nest monitoring data to see how specific factors may increase or decrease nest success.
Common Misconceptions to Watch Out For
  • Populations do not change. Shifts in population can happen in many ways. Some changes can happen slowly and take hundreds of years, like the gradual shift in traits from genetic change. Some changes can happen more quickly, such as a shift in population because of environmental changes like pollution.
  • Humans cannot control natural selection. Both plants and animals can be modified genetically by humans in a way that produces an organism with desired traits, but humans do not control natural selection. When humans modify a plant or animal genetically it is called artificial selection, and it is done for many reasons such as to create disease-resistance crops, bigger animals for food, and desired looks for specific dog breeds.
  • Environmental factors cannot change traits. Environmental factors can affect traits in both plants and animals. For example, the sunlight can affect the color of your skin, and it can also affect your health. Too much Sun exposure can lead to skin damage, but not enough can lead to a vitamin D deficiency.
