This research paper was conducted after an aerial poison operation in the Blue Mountains, in Otago, 2001.
What's interesting is the number of deer that were killed. For those that suggest "deer aren't killed in 1080 drops!", this research was conducted by Landcare Research.
20 birds were also found.
However, birds are allot harder to find dead, than deer. In one study it stated.."The mortalities of non-target birds from 1080 poisonings may be underreported because many die in their nests or roosts and are never found (Koenig and Reynolds 1987)."
It is illegal to kill deer with 1080, they are a non-target species.
As can be seen in this paper, and as is consistent with drop zones we have investigated, the non-target kill rates are higher than the target - as would be expected with a practice of dropping poison laced food from helicopters...

Abstract Incidental kills of deer during aerial -1080 poisoning of brushtail possums (Trichosurus
vulpecula) using baits containing sodium monofluoroacetate (1080) causes widespread hunter
opposition to this control method. We document the deaths of a large number of fallow deer (Dama
dama) after aerial-1080 poisoning in the Blue Mountains, Otago. Three deer fitted with radio collars all
died during the poisoning. Eight randomly located "search cells" (25-57 ha) were each searched twice.
One pig (Sus scrofa), 53 deer, 58 possum, and 20 bird (three native) carcasses were found. Deercarcass
density varied widely between cells (2.2-38.6/km2), reflecting differences in deer density but
apparently also the amount of ground cover. The total number of deer killed was estimated using
Lincoln indices. More fawns were killed than larger adult deer. Comparison with historical harvest data
suggested that between two-thirds and three-quarters of the deer present had been killed. This unintended
by-kill will have reduced deer impacts on native plants and the risk of Tb spread or persistence in
deer. However, such incidental benefits may not offset the increased indirect "social" costs likely to
arise from increased hunter opposition to use of aerial-1080 poisoning....
