Well, lead ammo is possibly responsible for the deaths of some kea - although if the key source of the lead contamination in back country areas (DoC- sponsored culling) is now not adding to the contamination levels through not using lead ammo and the carcasses that have been killed using lead ammo are now degraded so as to not be a food source for the birds, it would be safe to say that this source of mortality is likely reduced to statistically insignificant. Mortality from other sources of lead is likely still a factor, as I understand it a lot of the building project work removing lead flashings etc is now on a go-slow due to funding availability.
