Cox proportional hazards model, N = 225 observations, 140 events. Data contained only the two species from each group that visited the most (jackdaws/rooks and blue tits/great tits). The control condition served as the reference category for all object conditions, noncorvids for species group and rural areas for habitat type. An asterisk denotes an interaction term.
