When Great Horned Owl eggs hatch, the downy owlets are the size of newborn chickens. Their mother broods them day and night. A few weeks later, the owlets can be left alone while both adults resume hunting at twilight. Great Horned Owl young remain in the nest for about six weeks, then climb out onto nearby branches. They begin taking short flights at seven weeks, and can fly well at 9-10 weeks.

In Massachusetts, Great Horned Owls typically start nesting in the middle of February, raising their families in the later stages of winter. The female will incubate the eggs while her mate brings her food. Within a month, up to five eggs will hatch and the owlets will be closely guarded by their parents. Six weeks after hatching, the owlets will leave the nest and walk around. In another three weeks, the young owls will already have learned to fly. The parents will continue to feed and care for their offspring for several months, often as late as October. It is wise to stay away from young owls and their nests as Great Horned Owls are not afraid to attack if they feel their family is threatened!

Quite a treat, after searching high a low, and almost giving up, to just barely see the large “ears” of a female Great Horned Owl on nest this afternoon. She was sitting so low in the nest, her ears were a big challenge to find behind the sticks in an old nest.
Excerpt from Mass Audubon Breeding Bird Atlas I below.
The Great Horned Owl is the earliest nester of our native birds, usually laying its eggs between February 20 and March 25. The clutch almost always consists of two eggs, but the range can be from one to three, and sometimes four. One brood is raised each season, and on rare occasions a second clutch is produced if the first is lost. Incubation usually begins with the first egg and is performed by the female for 28 to 30 days. She will remain on the nest even during severe weather conditions and may be found covered with snow.

The young Great Horned Owls are becoming more mobile around their nest. They are stretching and testing their wings, and actively climbing around nearby branches. Quite a sight! Had a wonderful opportunity to observe the owlets late afternoon Wednesday in stunning late day sunshine.

The mother of the owlets keeps a close eye on her offspring. She keeps them close to her in the nest. They are growing quickly and hold their heads up on their own. The owlets are alert and very curious! This was a morning visit under bright sun and blue skies.

A short visit late afternoon under overcast skies, winds out of the NE around 13-15 MPH, with light rain and temps around 40 degrees. The owlets look a bit soggy and rain soaked…but hanging in there with warmer weather on the way!

A late afternoon visit to observe the Great Horned Owl on nest; the owlets were hunkered down and just out of sight as mother bear kept an eye on all nearby activities! She wisely uses the shade of a close by branch as a shield from the late day bright sunlight.

Another morning visit to the Great Horned Owl nest under bright sun and blue skies. The mother bear just watching over her owlets in a relaxed mode. She is looking over her right shoulder with one of the owlets beside her!
