European cuckoos and American cowbirds are “brood parasites” that laytheir eggs in the nests of other birds. The chicks are generally raised by“adoptive parents” whose own chicks receive less food and often arekilled by the larger intruders. What kinds of behaviors does naturalselection favor in the cuckoo and cowbird chicks? In the adoptive parents?

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.
Look at the two graphs in Figure 52-21. In which experiment did the parentals in the experimental group guard the eggs more closely? In which experiment did the experimental parentals guard the young more closely? Account for these differences.
In the eclectus parrot (Eclectus roratus), mothers sometimes take parental favoritism to extreme lengths by killing their sons, but never their daughters (Heinsohn et al. 2011). Sex-specific infanticide occurs more often at nests that can be flooded during the rainy season. Sons spend longer in the nest than daughters. Link this factor to why it might be adaptive for a parent parrot to kill a son in a vulnerable nest occupied by offspring of both sexes. Don't write from any online source..
According to Hamilton’s rule,(A) natural selection does not favor altruistic behavior thatcauses the death of the altruist.(B) natural selection favors altruistic acts when the resultingbenefit to the recipient, corrected for relatedness, exceedsthe cost to the altruist.(C) natural selection is more likely to favor altruistic behaviorthat benefits an offspring than altruistic behavior thatbenefits a sibling.(D) the effects of kin selection are larger than the effects ofdirect natural selection on individuals.
Identify the type of behavior. 1) 2) Goose. Bees attracted to the smell of the flower and flying towards the scent. _: Once initiated, it will run to completion and this could be observed in nesting behavior of Graylag 3)_ : A genetically program form of learning during developmental stage. Example: sparrow babies learn how to sing exactly at the same frequency as the mother. But if the babies grow isolated from their mother, the singing frequency will be different. 4) A turtle draws its head back into its shell when its shell is touched. After being touched repeatedly, the turtle realizes it is not in danger and no longer hides. This is an example of 5) : A child might stop throwing tantrums after his/her favorite toy is taken away after each tantrums.
