And I'd urge those in contact with their MPs to not only make THAT point but to also ask what has changed since David Cameron's Government rejected the Lead Action Group's call for a ban. Simply it will not wash that there has been sort of major discovery regarding lead between Cameron and now.
But...but ... those poor condors !
These are a few of the reports about the Californian condors.
We examine the claim that the most significant factor in the near extinction of the Californian Condor was lead poisoning through exposure to hunting ammunition.

Bear in mind that they admit the numbers were declining anyway, also bear in mind that man has been shooting , with lead , in those areas for at least 150 years.
California , a notoriously anti gun state, banned lead use for hunting in the condors areas in 2008.
They site non compliance as the reason this had little effect on lead levels in the birds.
However.....
'Lead poisoning from ingestion of spent lead ammunition is one of the greatest threats to the recovery of California Condors (Gymnogyps californianus) in the wild. Trash ingestion by condors is well documented,
yet the extent that trash presents a lead exposure risk is unknown. We evaluated 1,413 trash items collected from condor nest areas and nestlings in the Transverse Range of Ventura County, California, US, from 2002 to 2008, for their potential as a lead exposure risk to condors.
We visually identified 71 items suspected to contain sufficient lead to be of toxicologic concern. These items were leached with weak acid and analyzed for lead. Twenty-seven of the 71 leached items (~2% of the 1,413 items) were "lead containing" based on criteria of a leachate lead concentration >1 μg/mL, with the majority of these items (22; 81% of the 27 lead items) being ammunition related (e.g.,
spent bullet casings and jacketed bullets). Only three of the 1,413 items collected were lead containing but were clearly not ammunition related; the other two lead-containing items were unidentified.
Our results suggest that trash ingestion of nonammunition items does not pose a significant lead exposure risk to the California Condor population in California.'

So not only is it the bullets themselves that are the issue, but the shell casings too ?
But according to the report, anything else containing lead isnt an issue, can you see the problem here ?
However, lead exposure is not the only ongoing problem faced by the released or newly wild bred Californian condors, with the following from the same report:
“It is likely that fledging success would be reduced to zero again if chicks were not vaccinated for West Nile virus, examined monthly for ingestion of microtrash (i.e., small bits of refuse of human origin including items such as rags, nuts, bolts, washers, plastic, bottle caps, chunks of pipe, spent cartridges, and pieces of copper wire) and treated on site by veterinarians and field biologists”.
In California , as has been done here, a clear case of thinking of a 'solution' , and then creating the data that defines the 'problem'
