Life History, Abundance, Activity, and Special Behaviors
The breeding season is the best time to see and hear P. crucifer in the wild. Occasionally, individuals may be seen during the day in damp or rainy weather.The call of this species resembles that of sleigh bells when heard from a distance. A terminal upward slur characterizes the high, single, clear whistle that is repeated at intervals of approximately 1 second. In the background of small choruses, a trilling peep may be uttered by some individuals.
