It is that article Mike, but I'm still not convinced and I'll tell you why.
The RSPB state that the effect on wild birds is little difference to that of a thunderstorm.
Ok let's examine that. Birds are sentinent creatures in tune with and adapted to living in their environment.
They no doubt can sense an approaching thunderstorm, eg changes to air pressure, temperature, wind.
Thunderstorms approach from one direction and build gradually, birds have ample warning of an imminent storm and the rumble of thunder often but not always increases as a storm approaches.
Fireworks are a different kettle of fish entirely, there is no warning ,no changes in environmental conditions.
Just an immediate and often incredibly loud and sudden kerboom ! Enough to frighten and stress any creature.
Yes this is all conjecture but can the RSPB prove this is not the case ?
The decibel level of some modern fireworks is akin to a bomb exploding, the shockwave of sound is huge and any night flying creature for example a bat would no doubt be severely traumatised and possibly killed.
Same for Owls who would take flight and roosting birds.
Summer firework shows and even private parties are increasingly common, with extremely loud detonations that can happen at anytime.
This obviously is impossible to police and yes the RSPB can ask politely not to have Fireworks near sensitive wildlife sites but cannot stop it.
But what about the damage to urban and suburban wildlife ? Bats and Owls can live in close proximity to human habitations and Fireworks must impact on them.
The Tawny Owl is now an Amber listed species with long term population declines, who can prove fireworks aren't a contributing factor ?
The chemical cocktail released by fireworks also poisons the local atmosphere and must affect moths and insect populations in close proximity as well as the explosions themselves, all prey species for bats in particular.
The environmental damage done by fireworks is in my opinion unknown, but I suspect is an important contributing factor .
I would like to see the RSPB's science behind their statement, instead of just believing what they publish...
