Observations from a bat detector

Description

A dataset containing detections of audio call sequences from bats. It is a small subset of the data published by Lagerveld et al. (2023)

Format

A data.frame with 1,037 rows and 2 columns:

• RECDATETIME: datetime of the recorded bat call sequence

• SPECDESCSCI: scientific species name

It also contains an attribute named monitoring which is a data.frame containing monitoring periods at which the bat detector was active. Each row is a monitoring period, and it holds the following columns:

• start: start datetime of the monitoring period

• end: end datetime of the monitoring period

• time_on: time of day at which the detector is activated during the monitoring period

• time_off: time of day at which the detector is deactivated during the monitoring period
