1. What is the main purpose of the lecture?
    1.   To compare active habitat selection with passive habitat selection
    2.   To show that most habitat preferences in animals are learned
    3.   To compare the habitat requirements of several bird species
    4.   To examine the consequences of habitat selection by animals
  2. What element of the plover’s habitat in California was threatened?
    1.   The availability of food
    2.   The availability of water
    3.   The safety of nests from human activity
    4.   The protection of nests from predatory birds
  3. What does the professor illustrate with the example of the blue warbler?
    1.   The relationship between human activity and habitat loss
    2.   The relationship between habitat and reproductive success
    3.   The advantages of habitats with low vegetation density
    4.   The reproductive advantage that young warblers have over older warblers
  4. Why does the professor mention the population density of blackcaps in two different habitats?
    1.   To explain the similar reproductive rates in the two habitats
    2.   To explain the relation between a species’ population density and its nesting behavior
    3.   To illustrate the advantages of a preferred habitat over a secondary habitat
    4.   To illustrate the possible impact of making a poor habitat selection
  5. according to the professor, why did some blackcaps choose a secondary habitat?
    1.   They were following a moving food supply.
    2.   Their preferred habitat was taken over by another bird species.
    3.   Their nesting sites were disturbed by human activity.
    4.   Their preferred habitat became too competitive.
  6. Listen to the Track
    1.   She realizes that she just contradicted a statement she made earlier.
    2.   She is about to discuss another aspect of the topic.
    3.   She thinks the answer to her question is obvious.
    4.   She wants students to recall a case that she has already discussed.
