In the greater ani (Crotophaga major) (Riehl 2011) and the acorn woodpecker (Melanerpes formicivorus) (Koenig et al. 1995), a group of females shares the same nest.

Polygyny is a common mating system in nature. Which one of the following scenarios is LEAST likely to result in a polygynous mating system?

Suitable tree holes for oviposition are rare and females must mate with the resident male in exchange for access to the oviposition sites. Male Bengal tigers defend large territories that contain food sources. Female Bengal tigers visit male territories to mate. The density of the Bengal tiger is extremely low that male tigers rarely encounter more than one female in their lifetime. In the bumblebee-wolf Philanthus bicinctus, females are unreceptive until they finish constructing the long underground burrow as nest sites. Males search for locations containing a number of newly constructed burrows and attempt to control these sites against the intruders. Your cousin Peter…
