Your message already came through yesterday. Maybe you have got
no response and so you think it didn’t come through. Not everyone knows the
word “tiercel” as meaning male, or the odd use of “falcon” as meaning female.
I think your question is very narrow and detailed, there would
not be many who have a detailed answer. I don’t know and it is not a priority. Yes
I have opened the link to skim through that book but no, I have not and surely
won’t be reading all that text. From general memory of these birds and all I
have seen and read, I thought it seemed unusual to suggest that the males take
such a big role. So I suspect your question and use of “usually” is without
a verifiable answer. Is it possible, or I suggest, that the source you refer to
mentioned “Records by observers of this breeding pair report the
tiercel as the main carer of the nest-young” simply because that is odd?
Is that issue covered? Like we will report a rare bird because it is odd. Or
maybe they did not know then. In which case, that is half the answer to your
question. Could it be that the original mother died and he recruited another
less interested female? It is over a century ago. There must surely be books
that describe the usual, plus newly the many webcams. Much more must be known
since 1913. What does HANZAB & HBOTW say? It would be strange if such a
widespread homogenous species varied in sex roles around the world.

Greetings, fellow home-birders.
Just now I'm reading a reprint of Heatherley's 1913
"Peregrine Falcon at the Eyrie" (also viewable at—
). Records by observers of this breeding pair report the
tiercel as the main carer of the nest-young. (Odd & instructive
characterisations of the falcon also appear, inconsistently, & in line with
the confused contemporaneous human-social morés around females.)
The location of this study is discreetly blurred, but
could've been Scotland.
Anyone know if tiercels are usually the main brooders,
carers, & providers of UK peregrine young at the eyrie, once the falcons
