Fighting may leave birds with injuries or even kill them. Mating occurs only approximately every five years, with the ripening of the rimu fruit. In mating years, males may make "booming" calls for 6–8 hours every night for more than four months. [55] The sound of a kākāpō booming
The northern saw-whet owl makes a repeated tooting whistle sound. Some say they sound like a saw being sharpened on a whetstone. [21] These calls are usually produced by males searching for mates, so they can be heard more often beginning in January and continuing through the end of the breeding season in early July. [22]
Calls are sometimes distinctive enough for individual identification even by human researchers in ecological studies. [31] Call of black-capped chickadee (note the call and response with a second more distant chickadee) Over 400 bird species engage in duet calls. [32] In some cases, the duets are so perfectly timed as to appear almost as one call.
The barred owl is a powerful vocalist, with an array of calls that are considered "spectacular, loud and emphatic". [42] Calls probably carry well over 0.8 km (0.50 mi). [43] Its usual call is a series of eight accented hoots ok-ok-ok-ok ok-ok-buhooh, or the "typical two-phrase hoot" with a downward pitch at the end.

The northern hawk-owl generally starts its mating rituals at the beginning of March. [11] After calling and pairing is complete the northern hawk-owl will build a nest and start to lay eggs. On average the northern hawk-owl will lay 3–11 eggs per brood. The nest sites are usually the tops of hollow stumps of old dead spruce trees.
The call serves to attract females and becomes increasingly persistent as time without a mate passes. [15] [16] Some research suggests that unlike the Northern saw-whet owl, a variation of the male call persists after mating throughout the reproductive cycle for defense, aggression, or to convey information about prey. This suggests that ...
