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.
Although barred owls prefer to nest in tree cavities, this species is known to use empty hawk nests, crows nests, or squirrel nests. A clutch of usually two to three eggs (range is from 1 to 5) will be laid in the nest; the female incubates the eggs for 28-33 days.ecause barred owls rely on large tree cavities for nests, they are most often found in old growth forests. In areas where logging has reduced the extent of old growth habitats, barred owls may become threatened.
