Zebra finch group calling zf4f

Calling patterns of four female zebra finches, recorded in an indoor aviary in London in 2015. Two CSV files are included: each one describes a one-hour session. The CSV columns are: time (seconds), duration (seconds), microphone number (0-3). Note that the order of birds is swapped between the two days, so microphone number 0,1,2,3 in session2 corresponds to the same birds as microphone number 3,2,1,0 in session3. (We refer to this dataset as "zf4f".)
