The Venice notes are a feeble attempt at liability mitigation. Specifically, the goal is to cover off the concept of "duty of care" and "duty to warn". In the event of an accident or incident you can bet the first question the crew will be asked is "did you have the weather radar on".
The good news is that with only some minor effort this will be shown in court as utterly ridiculous.
This warning/requirement is much like airports that constantly broadcast "Pilots take caution due to bird activity" in ATIS messages. Eventually this becomes "white noise" and pilots ignore it. This type of general or blanket warning will inevitably be tested in court and is most likely to fail the test of "reasonable standard of care" and "due diligence".
Unfortunately, in the field of airport wildlife management and bird strike mitigation there is a belief that this is "nature and it can't be changed" and even more concerning to much pseudo-science, urban legends and people selling products that should only be sold at 0300 on infomercials.
