A new map gives a detailed picture of "hot spots" where birds of prey have been poisoned.
The document, put together by agencies involved in the fight against wildlife crime using Scottish Government data, revealed 132 such birds have fallen victim to poisoning since 2004.
But the data used to draw up the map also showed a marked fall in the number of birds of prey being poisoned.
From a peak of 38 in 2004, the number fell to 16 in 2008.
Ministers hailed the publication of a map underpinned by official data as a "significant step forward" in efforts to tackle the problem.
There has often been disagreement between conservationists and land managers over the level of crime against birds of prey and it is hoped the map could lead to more focused action on the issue.
The biggest "hot spot" is in south, central Scotland, where 12 incidents of poisoning are recorded.
A further "hot spot" is in an area bordering Midlothian and the Borders, were five poisonings were reported. Five were also reported in the eastern Highlands.
Buzzards suffered the greatest casualties, with 95 ingesting poison, according to the map.
Next came red kites, with 22 reported poisoned and goshawks, peregrine falcons, tawny owls and sea eagles also figure on the list.
