A song thrush, busy feeding a nestful of babies somewhere in the park.
The song thrush is red listed as a bird of serious conservation concern in the UK. The British Trust for Ornithology has monitored bird populations for decades and found that the population of song thrushes in England declined by more than 50% between 1970 and 1995. This decline was most pronounced on farmland, where the population decreased by about 70%. There has been a partial recovery in numbers during the last decade.
Here is the thrush’s song:
