Passage
Researchers often treat community science data as less reliable than data collected by specialists. A bird-counting project complicated this view when volunteers consistently detected rare species that short specialist visits missed. One interpretation was that volunteers had better skill; another was that their frequent presence increased detection opportunities. The second explanation fits the records, since specialists confirmed many reports once alerted. Volunteer data may be valuable not because volunteers replace experts but because they observe more often.
