Chorusing:
Audio recording by Keith Coleman.
Chorusing Phenology: The black outlined dots denote the Julian date (day of the year; 1 January = 1 to 31 December = 365) an observation was made. The thin red line depicts the range of dates between the beginning of the first, and end of the fourth quartile (excluding outliers; Tukey method). The thick light blue bar represents the second and third quartile (interquartile range; the middle 50% of all observations). Only one observation per Julian date is included in the graphs; so a date with multiple observations carries the same weight as a date with only one observation. The vertical bars correspond to the 12 months of the year; January through December.
