I too have noticed the difference in miner calls, although I think there is
another dynamic that is going as Eric mentions below.
Miners give more leisurely calls for soaring birds at a long distance than they
do to imminent danger. I agree with Eric on this point in regard to the
falcon's rapidity of arriving in the proximity to miners, but I've also noticed
very similar calls when they are surprised by accipiters.
It appears to me that there is a definite escalation in call intensity and
frequency as a bird of prey approaches.
On a related note, there is s definite period of the year (late summer and into
autumn) when the birds clearly make mistakes about danger. They give alarm
calls for Needletails, aeroplanes and sometime swallows and I think there is a
correlation between the numbers of young birds and these mistakes. A period of
learning alarm calls and recognising what is an identifiable threat if you will.
I've definitely noticed a marked difference in call between aerial danger and
danger on the ground, such as a lace monitor, cat or human, similar to the
vocabulary that vervet monkeys display. The ground call is not the higher
pitched call, it's the yaap, yaap, yaap call.
