Pearl-spotted owlets call by day and night, especially before breeding, but are quiet when nesting. [4] They have a distinct call: a loud series of shrill, short whistles that accelerate in tempo and rise in volume to a crescendo of long, loud whistles that descend in pitch and volume, peu peu peu-peu-peu peeuu peeeuu.
A high melatonin level is associated with sleep and low levels are associated with high alertness and foraging activity. Spotted owlets, however, show only a slightly lower melatonin concentration at night with a slight increase in the early afternoon. Other owls such as the barn owl show little day-night variation.
The young owlets fledge at about 10 weeks. Usually, chicks are born in mid-June or early July. By the end of July, they are almost always fledged and ready to set out on their own. After the young hatch, the female elf owl watches over them in the nesting cavity while the male often hunts for the young and the female herself.

When nesting, the male hunts and feeds the female at nest, and the female feeds the young. The nestlings fledge after 30–32 days. [19] A study conducted in the forests of Madhya Pradesh revealed that the forest owlet is a generalist predator that consumes a variety of small mammals. [20]
Their call is a series of fast, bubbling hoots, uttered at night and frequently repeated. These fast, staccato notes followed by a longer and higher-pitched ‘hoot’ are extensively used during breeding season and pairs of owls often sing together. [3] The northern white-faced owl has a very different two-note call.
