Table 3. Monthly and overall occurrence of song types for each of the four sites, including total detection effort each month, total duration of song detected, total number of phrases contained within identified song bouts, as well as percent phrase type and dominating song type. The dominating song type for each site was defined based on whichever phrase type (AB or ABB) comprised more than fifty percent of the total number of phrases detected. The greatest monthly durations and the dominating song type for each site are highlighted in gray. Months when the dominating song type differed from the overall dominating song type observed at a particular site are marked with an asterisk. Only months that contained identifiable song are included for each site. Data were not available for the inshore sites during the beginning of September 2009 or August 2010 (Table 1).
