They are polyphagous in coniferous trees (mainly feeding on Pinus sylvestris, Pinus mugo and Pinus nigra, but also on Picea abies and Abies or Larix species).
This is the case in England where the species seems to be on the increase and is found on dry heathland with patches of bare stony ground and among sparse Ulex europaeus and Pinus sylvestris.
Scots pine Pinus sylvestris and Larch Larix species (particularly plantations of L. decidua)
The Scottish Crossbill breeds in the native Scots pine (Pinus sylvestris), Caledonian forests of the Scottish Highlands, but (perhaps surprisingly), often also in forestry plantations of exotic conifers, notably Larch (Larix decidua and L. kaempferi) and Lodgepole pine (Pinus contorta).
