About
the Song Thrush
While the Song Thrush is a familiar
bird, often thought of as a year-round resident, its movements
are actually more complex than first appears (see map). Some
birds move west in the winter, will others move south into
France and Spain. Others pass through on passage.
Fruit is important during autumn
and winter but at other times of the year these birds feed
on invertebrates, especially earthworms and snails.
Song Thrush numbers began to
decline in the 1970s and BTO monitoring data have been valuable
in helping to pinpoint the reasons behind the decline.
While many people associate the
Song Thrush with snails, these molluscs are only important
at certain times of the year (late summer) when dry conditions
make other foods harder to find.
