Output from Lotek LAT program for Lotek time-depth recorders attached in 2009. There are two folders: TDR_ACC_H2O and TDR_rearing. The birds in the folder TDR_ACC_H2O were injected with doubly-labelled water, which does not statistically affect their behaviour (see Elliott et al. 2013. PNAS). For the first 24 h, they were also equipped with an accelerometer (see http://datadryad.org/resource/doi:10.5061/dryad.40gk7 for details of deployments). Accelerometers were also attached to some of the birds in the second folder, which were observed for feeding watches. The meta-data file has details on which had accelerometers attached. Within each folder, there is a subfolder with the band combination (9 digits beginning with 1186 or 5 digits). For band numbers with 5 digits, the prefix was 996 so that the total band combination was 996XXXXX where XXXXX is the band number provided in the subfolder heading. The band combination for each individual ties the TDR recording with the meta-data (sex, age of the bird). Each folder includes two binary files (which can be read into the Lotek program) and a text file. The text file has four columns: the record number, the date-time, the pressure in dBar (converts directly into depth in m) and temperature in degrees Celsius.
