Abstract
The main characteristics of dawn chorus, as observed at Wellington, New Zealand, between July 1955 and October 1956, are presented. These are: no general correlation with whistlers; a strong correlation with simultaneous local magnetic variations; a pronounced diurnal variation in activity, with the peak occurring near 0400 hr local time; and possibly a weak seasonal variation in activity.https://doi.org/10.1071/PH570286
