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.
A Screech Owl will find a new mate if one of the pair dies. It has been reported that male Screech Owls will on occasion form pair bonds with a second female in good habitat with abundant prey.reedingPairs of screech owls mate for life after a somewhat elaborate courtship that involves the male swiveling his head, bobbing his body up and down and winking his eyes. If the female appreciates his efforts she moves close, they touch bills, and mutual preening ensues.
