A breeding pair of birds receives help raising their young from an unrelated male bird. This behavior is termed cooperative breeding and in some ways this seems like an evolutionary paradox since helpers seem to be acting in ways that increase the fitness of others at their own cost. .How might providing this assistance improve the fitness of the unrelated male bird? O Increasing the fitness of the unrelated offspring directly increases the unrelated bird's fitness The cooperative relationship helps the unrelated male survive until he can find a mate and produce offspring of his own Rearing unrelated offspring delays sexual maturity in the helper bird so he has fewer offspring over the course of his life. Because he does not ever produce offspring of his own, the helper bird has a longer and healthier life.

Acorn woodpeckers (Melanerpes formicivorus) stash acornsin storage holes they drill in trees. When these woodpeckersbreed, the offspring from previous years often help withparental duties. Activities of these nonbreeding helpers includeincubating eggs and defending stashed acorns. Propose somequestions about the proximate and ultimate causation of thesebehaviors that a behavioral biologist could ask.
In a species of birds, males court females by dancing and subordinate males are seen to join a dominant male and help in his dancing displays, though the subordinate receives no mating opportunities. If the subordinate male DOES NOT inherit the dominant male's territory upon its death, how would you explain this cooperative behavior? O Altruism, because the subordinate is receiving direct benefits O Mutualism, because the subordinate is receiving direct benefits O Altruism, because the subordinate is receiving indirect benefits O Mutualism, because the subordinate is receiving indirect benefits
Most Swiss starlings produce four to five eggs in each clutch. Starlings producing more than this have reduced fitness. Which of the following statements best explains this situation? O The starling parents do not care for their young, reducing their fitness. O The ecosystem can only support two offspring, reducing the fitness of both populations. O The population of starlings have limited resources to care for their young. O The starlings have fewer habitat options and fewer offspring, reducing their fitness.

Much of animal behaviour theory is rooted in optimality, using this theory and thinking about territory size, construct a well-labeled graph below: sketch two lines (one for costs, one for benefits), with an asterisk (or symbol of your choosing) indicate the theoretical optimal territory size and in one sentence, explain why that particular territory size is optimal . Territory Size Costs/benefits
There are three chief ideas of the handicap principle: 1) Animals communicate with éach other throughn sigi must be honest, and 3) honest signals are expensive. Stotting behavior (up and down jumps gazelles exhibit when they spot a predator before the gazelle runs away) often results in the predator leaving before it attacks, presumably because the predator knows it won't easily catch that gazelle. This clearly is an example of the handicap principle based on the three ideas. True False

How does a hummingbird’s body shape influence its ability tohover?c. How do alarm calls affect prairie dog fitness?d. Which cues do monarch butterflies use during migration?
In 1983 a population of dark-eyed junco birds became established on the campus of the University of California, San Diego (UCSD), which is located many miles from the junco's normal habitat in the mixed-coniferous temperate forests in the mountains. Juncos have white outer tail feathers that the males display during aggressive interactions and during courtship displays. Males with more white in their tail are more likely to win aggressive interactions, and females prefer to mate with males with more white in their tails. Females have less white in their tails than do males, and display it less often. (Pamela J. Yeh. 2004. Rapid evolution of a sexually selected trait following population establishment in a novel habitat. Evolution 58[1]:166-74.) Refer to the paragraph on dark-eyed junco birds. The UCSD campus male junco population tails are about 36% white, whereas the tails of males from nearby mountain populations are about 40-45% white. The founding stock of UCSD birds was likely…

How does parental care benefit the mother's inclusive fitness? C. Why do some species have parental care but not others? D. Do mother birds get better at caring for their offspring over time?
Which of the following would not be a reason animals typically exhibit dishonest behavior? To purposefully decrease another animal's fitness To avoid conflict To stop extrapair copulation To increase their own fitness
Use Verbal description of results from graph and then Interpret the graph for Foraging in Mixed Species Flocks sccenario in foraging lab. The interpretations must include Were the results expected and Did they support the hypotheses? If so, state the biological significance of the results from graph. If the results deviated significantly from expected results, discuss the hypotheses onthe basis of expected results and include an explanation of why this might be so. Lastly, state the conclusions drawn from the experiment and their biological relevance. Hypothesis: the assumption underscores the enhancement of foraging efficiency associated with the establishment of mixed-species flocks, emphasizing the advantages of cooperation and safety in numbers.
