heard plausible but unproven explanations of the last, and know
of none of the first two (though I haven't looked hard).

Having a sparrowhawk here has reduced my collared dove population to nil.

Interesting as here, despite a few sparrow hawks (I say a few thanks
to simultaneous sightings) and buzzards flying a bit higher but
swooping down occasionally, the collared dove population has trebled
to 3 pairs this year (they have occasionally arrived together). They
seem very brave and don't stop feeding if we or cat walk out into the
garden but they do get aggressive if smaller birds try to get at the
bird table when they're on it.
