check the above link it's talking about the most famouse birds which feeds on Juniper trees.

The Fieldfare is a large thrush - just a little smaller than the Mistle Thrush - with very bold plumage. They are winter visitors from Scandinavia.

Adult male and female Fieldfares are similar in appearance, except that the female is generally duller and browner.

The male has blue-grey crown, nape, and rump; chestnut brown back; black tail; and a buff breast with black streaks that also extends to the flanks. The underwing, especially the "armpit", is white, and it is this and the pale grey rump that are most noticeable when in flight.
