Communal brooding, which can occur as a result of brood amalgamation or communal parental care, is a common alternative brooding strategy observed in many precocial bird species. Although the occurrence of long-term communal brooding has been documented in numerous waterfowl species, and to a lesser extent in gallinaceous species, the occurrence and mechanisms facilitating temporary or short-term communal broods is less understood. During the 2013 and 2014 breeding seasons, we anecdotally observed temporary communal brooding in 3 Northern Bobwhite (Colinus virginianus) broods and one Scaled Quail (Callipepla squamata) brood. We present 3 mechanisms that may explain the occurrences of temporary communal brooding: (1) cool weather conditions observed at intermittent intervals throughout the breeding season, (2) predator avoidance behavior, and (3) a random proximity mechanism that triggers communal brooding in these highly gregarious bird species. It is our hope that these observations will facilitate future research investigating the impact that temporary communal brooding may have on survival and recruitment of gallinaceous birds.
