This maintains the heat transfer between steam and liquid to a maximum. Figure 3 shows a temperature profile when saturated steam is used. The difference with the previous diagram is that there is now a layer of condensate on the heating surface and steam temperature is constant.
As a general rule Owls are monogamous - pairs are comprised of one male and one female, neither one of which has any involvement with other nesting birds. With some Owl species the pair bonds last only for the duration of the breeding season, especially if the species involved is dispersive or migratory.
They usually build their nests about as high up as the roof of a one-floor house. A mother Screech Owl will lay 3 or 4 eggs in their nests, and will sit on them for about 26 days, until the baby owls hatch. What they eat: Screech Owls hunt for food at night, when they can see much better than people can. Most owls look for food from a tree branch, but screech owls hunt while they fly around. When they find food, they fly down very, very quietly and catch it. Then they take the food up into a tree and tear it to bits and eat it. Screech owls like to eat little birds, mice, shrews, and other small animals.
