Possible - but unlikely. They only rear one clutch of eggs per year - and that takes almost all of their time. Rearing another clutch in a second nest at the same time would be near impossible.
At night in a barn
most owls don't but barn owls come out day and night.
Owls do not build nests. Some are cavity nesters, like the Common Barn Owl and the screech owls. Barn owls have been known to nest in: old buildings, caves, in palm trees, anywhere they can find a little hidden area. Owls that are not cavity nesters will use the nests of other large birds: crows, ravens, hawks. Some nest on the ground (Snowy Owl, Short-eared Owl), others will nest on ledges or in old buildings. As far as nest building goes, barn owls come closest in that the female will shred and arrange the pellets (regugitated undisgested bones and fur) to make a nice warm "carpet" for the eggs and chicks.
A typical nest is around 5 feet in diameter. Eagles often use the same nest year after year. Over the years, some nests become enormous, as much as 9 feet in diameter, weighing two tons.
Every owl is different, but barn owls are nocturnal, which means they wake up at night and go to sleep as dawn arrives. There is no set exact time, but that is the general time.
Generally, a Barn owl will sleep during the day, hunting from dawn until dusk, unless the Barn owl has had a hard time hunting or is looking after its young, when a barn owl will hunt during the day.
There will be a slight decline in the Barn Owl population. This is because voles have the highest occurence and when that occurence disappears, the Barn Owls will have harder time finding food and won't be as easy.
During its free time, a barn owl typically engages in activities such as preening its feathers to maintain cleanliness and insulation. It may also roost quietly in a safe location, resting and conserving energy between hunting sessions. Barn owls are primarily nocturnal hunters, so their free time is often spent in a state of alertness, ready to take flight when darkness falls. Additionally, they may interact with other barn owls during mating season.
No, mud swallows typically build their nests during the day. They gather mud and plant material to create their nests, which are usually constructed on the exterior of buildings or cliffs. Nighttime is generally a time for resting and sleeping for mud swallows.
All owls are different in many ways for example there is a snowy owl and a barn owl. A snowy owl is very larger and white while a barn owl is smaller and has a brownish color. All owls change from time to time in color and depends on there breed and their main colors. The British Barn Owl is a pale cream color. Others have distinct dark markings.
not all the time, females are usually larger with darker markings
Owls are nocturnal animals, which means that they are most active during the night. Being birds capable of flight, they choose to live in large holes within trees and sometimes rock crevasses. This provides them with ample protection from the elements. Most owls prefer to live in trees, however deforestation is slowly eating away at the available habitat. Good news for the owls though, they are the least concern on the extinction chart. Not all owls are nocturnal, most owls do hunt at night to avoid competition with other birds of prey. However some species such as burrowing owls and short-eared owls feed during the day. Pygmy owls feed at dusk or dawn. Each species have adapted to avoid competition for food.
