Table 2.

Contingency table of polygyny type (facultative or obligate) in species hosting (or not hosting) obligate inquiline social parasites, before phylogenetic correction.

	Host species	Non-host species
Facultative polygyny	29	90
	93.6%	77.6%
Obligate polygyny	2	26
	6.4%	22.4%

Polygynous species for which information regarding obligate or facultative nature of polygyny was missing were excluded from this table. Percentages represent the proportion of host and non-host species that are facultatively or obligately polygynous.
