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.
Barred Owls have a distinctive hooting call of 8â9 notes, described as âWho cooks for you? Who cooks for you-all?â This call carries well through the woods and is fairly easy to imitate. During courtship, mated pairs perform a riotous duet of cackles, hoots, caws and gurgles.
