Some years back I had to do a damage inspection after a report of a bird strike on a 727 at 23000 ft over the Persian Gulf. We found feathers trapped in a lap joint at the bottom of the radome - looked like from a large raptor. Have seen some horrendous damage to engines by bird strikes - the worst being on a JT 9 that took 7 geese in the fan.
I have some photos here of a bat penetrating an A330 flap, but they may be too confronting. I had two bird strikes on one DHC-8 flight...the second one an owl that caused the loss of the wing/body fairing. It made a very disconcerting noise when it hit. (150 kts or so on approach)

I recall many moons ago being told that Speedbird had a ‘bird speed’ (irony I know) of about 307 knots below 10K on the 767. I’ve never seen it written in a manual either before or since that time.
Think the restriction of 313kts below 8000ft was also a limitation in another UK operator of the 757/767. It was/is contained in the limitations section in BA even after the 757 was retired so maybe it was a CAA airworthiness restriction, there is a lower Mmo limit for G-reg 767s as well (0.84).
Like I said previously, the Imperial Standard Bird is a different ornithological ball of feathers to the SAE Bald Eagle.
Or, put another way, the old ARB and CAA used to file their own flightplan.
With Brexit, will it all happen again?
Hence local certification limitations than can vary markedly from the original state of certification ---- The Queen's Own Chairborne Aviation Regiment have to justify their not inconsiderable salaries.
Tootle pip!!
