Never trust a weatherman unless they have excessive facial hair or a speech impediment!
If lots of people are passing back reports of bird activity or it's a recorded and statistically noted breeding area/ whatever then why not have that extra situational awareness?
All I am saying is that as someone who has flown round East Anglia well below 500ft (legally
) and made use of Anglia Radar etc I would have made use of all those NOTAMs had I been passing through, and I suspect any rotary operators would have as well.
