Document Summary
Types of parental care establishing and maintaining nests or territories production and provisioning of gametes care of fertilized eggs provisioning after hatching or birth care after nutritional independence. Parental investment over a single season individual with lower parental investment loses less if no offspring are raised any success of the partner will benefit the deserter . Kentish plover tested value of parent care by removing each parent. Hypotheses that explain value of biparental care in habitat a: more frequent feeding trips better defense against predators. Hypotheses to explain differences between sites a and b: site b faster chick growth rates = higher food availability site b had higher quality parents. Kentish plover tested benefits of deserting in each sex by simulating desertion difference in desertion between sexes is a consequence of biased operational sex ratio . Parental care in the northern flicker large clutch sizes (up to 13 eggs) both sexes incubate eggs need to be constantly incubated.
