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.
Birds do not mate for pleasure, only for procreation, and many male birds are sterile outside the breeding season. The exact timing of when bird pairs come together for successful mating varies, and the timing evolves for different species to give the resulting chicks the best chance of survival.o pinpoint when the bird mating season occurs, watch for: 1  Warming temperatures and blooming flowers that show the change of seasons. 2  Birds claiming territory and becoming more aggressive toward intruders, particularly males.
