  • Incubation Period: 24-27 days
  • Nestling period: 26-35 days
  • Egg Description: White

The great thing about ferruginous pygmy owls is that these creatures are monogamous and they find a partner and form a lasting lifelong bond with them. Their breeding season takes place during late winter and goes into early spring. During the nesting period, the pair will nest within tree holes or a cavity within the cactus often left behind by woodpeckers.

After the meeting, the female will have anywhere from 2-7 eggs and she will incubate these eggs for 24-27 days. During the incubation period, the male will bring the female food and continue to do so until the first few weeks of hatching have passed. The owlets fledge after reaching roughly 30 days old. At this point, they become independent creatures and move away from their parents roughly 3 weeks afterward.

From its perch, the small owl will recognize its prey and fly very quickly and rapidly toward the animal that it is hunting. During this quick flight, he will grab its prey using its talons and it will capture the creature to bring it back to its nest to feed its loved ones.

At night, ferruginous pygmy owls are known to become vocal. They are also very vocal during the period of sunrise and sunset. Mainly, it gives a whistling call that sounds like hoo-hoo-hoo-hoo.

They enjoy spending their time by themselves, but they also tend to remain in pairs during mating season. They have an interesting way of moving in trees. Instead of flying from branch to branch, they like to walk and hop from one branch to another. But they also move using short flights that take them directly to the location of their choosing.

While flying, they look very similar to many woodpeckers. Their flight consists of undulating in motion. When things appear dangerous or exciting, the ferruginous pygmy owl Wilcock hits its tail and moves it back and forth from side to side.
