PS: why is it so?

Thinking about all your replies, two notions occur to me –
First, that it’s likely characteristic of this literary form (i.e. the journal-style natural history) that it telescopes time, so that sightings of such a “glamour” species seem populous within the book’s geography due to the author’s thrilled recording of every peregrine’s passage, within compressed time, & at disproportionate coverage compared to all other species recorded.
Secondly, the northern-hemisphere peregrines are migratory (in contrast to the sedentary habits of Australian breeding adults [Debus 2001]) – so at any one location surely here we will rarely see more than the same pair, & where the habitat is unsuitable are unlikely ever to see the species. Britishers, though, in the Ansell DEEP COUNTRY example, will see the species coming & going, as well as those seasonally staying.

Falcons particularly seem to course the British skies as populously as swallows. When you think how rare & fortunate it is to see a Peregrine streak by in Australia — Is it really like that in Britain? … & if so, why are the peregrine falcons so sparse here?
