Final answer:
Polygynous mating tends to be high when males do not contribute to paternal care, with examples including resourced-based polygyny, harem systems, and lek systems.
Step-by-step explanation:
In scenarios where males do not provide paternal investment, polygynous mating is often high. This system occurs because one male mates with multiple females, but cannot feasibly provide care for all the offspring produced. Thus, females predominantly undertake parental care. Examples of polygynous mating include resourced-based polygyny, harem mating structures, and lek systems. One bird species that demonstrates resourced-based polygyny is the yellow-rumped honeyguide, with males defending territories rich in resources such as beehives. The harem mating system is exemplified by elephant seals where an alpha male controls and mates with multiple females within his territory. Lek systems are characterized by males performing communal displays to attract females, observed in sage grouse and prairie chickens among birds.
