Yes, it's a female Tachina fera.
Some important characters (english/german):
fera:
fore tarsi yellow (brown) - male: fore claws very long
approx. as long as tars 4+5
abdomen: band on tergite 5 narrowed (arrow)
magnicornis:
fore tarsi black - fore claws short
abdomen: band on tergite 5 broadened

einige wichtige Merkmale
fera:
vordere Tarsen gelb (braun) - Männchen: vordere Krallen sehr lang
(ungefähr so lang wie die beiden letzten Tarsenglieder)
Abdomen: dunkles Band auf Tergit 5 verschmälert (Pfeil)
magnicornis:
vordere Tarsen schwarz - vordere Krallen auch beim Männchen kurz
Abdomen: dunkles Band auf Tergit 5 verbreitert

Greetings, Eric

Eric is totally correct, but be warned all features are variable and some species seem genually intermediate. Width of vertex in male and esp. shape of male genitalia are highly distinctive.

So never base your ID on one feature only ( unless male genitalia)

That said, this is rock solid female fera, indeed.

Theo.
