Fig. A.1. Expected (red) and observed (blue) frequencies of the number
of individuals that were detected at different number of visits. Graphs
in the first row were obtained from data gathered from all individuals
and graphs from the second row were obtained from data of individuals
that were seen at least twice during the year. In all graphs, blue bars
(observed data) and red bars (expected data) rarely overlap. We observed
many more individuals than expected only once or twice if all were
long-term residents when detectability rate was assumed to be 0.33.
Table A.1. Statistical summary of the expected and observed number of
visits at which individuals were detected during all three years and
using two data sets: (1) “all data”, information from all detected
individuals, and (2) “> 1 sightings”, information from
individuals detected at least twice during the year. All the expected
mean visits were statistically different from the observed mean visits.
