There is a resident pair of Mistle Thrushes in my local park. The resident male has been singing occasionally since the end of November from a high post on the tallest trees. Mistle Thrushes' song is reminiscent of the Blackbird's but with shorter, more repetitive, mournful phrases that carry quite far. Up to five birds gathered on the grass before Christmas, and when the snow arrived the locals birds had to share the few clear patches of turf under the trees with a flock of immigrant Redwings and a lone Fieldfare in search of earthworms and other invertebrates. Mistle Thrushes are large and bossy, and if the other thrushes get too close, they are chased away without trouble. Resident birds have a head start in the breeding season. They know their patch and as soon as conditions are right they can start nesting right away.
The male was singing again in the last few days without snow, while the female fed on the grass.
