If it is causing that distress (and this is normal), I would like to suggest removing the mirror or covering it, during the start of the breeding season.

A couple of years ago a large mirror with a crack was exiled to the outside wall of the back of the garage.
The first spring, a White-browed Scrubwren took exception to the other, persistent White-browed Scrubwren transgressing its territory in the mirror, with daily attacks over several weeks.
Earlier this year a male Superb Fairywren did the same for a few weeks.
Then a female Magpie Lark for about a week.
Now a Red Wattlebird is engaging with very vigorous combat with its rival in the mirror.
