Urbanization of the environment poses many challenges to biparental avian species, however, it is unknown if urbanization affects pair coordination of provisioning behavior. We observed the parental behavior of pairs of house wrens (Troglodytes aedon) at active nests in an urban and rural site to explore whether alternation and synchrony differed between urban and rural environments. The urban site had significantly fewer parental visits than the rural site. Pair coordination, measured by alternation and synchrony, was significantly lower at the urban site. We provide evidence that pair coordination is decreased in urban environments, supporting the idea that urbanization may have a negative effect on the fitness of biparental avian species.
