Hawk-Owl Nest Monitors measure all activity into and out of entrance holes with one second accuracy. The events are recorded in .csv spreadsheets which are easily analyzed in Excel, Igor, text editors and many other common tools. The spreadsheets can substantiate your analysis, however the 'aha moments' will come as you scroll through your data with Hawk-Owl's free NestView Software. NestView clearly reveals gradual trends like steadily increasing food deliveries as the young grow larger, or sudden changes like fledging and predation. NestView also makes it easy to spot anomalies like an occasional midnight event.
