About the Song Thrush

 

The song thrush is the loveable speckled garden bird that all adults grew up with, right up there in popularity with the cheeky robin and the acrobatic blue tit. Once more common than the ordinary blackbird, its fortunes have taken a turn for the worse.

Breeding and Nesting

Song thrushes are found in woodland, parks, gardens, hedgerows, grassland and farmland. Hedgerows are a particular favourite, providing food, shelter and a place to nest. Their nests are sturdy constructions consisting of a cup of grasses, twigs and leaves, lined with mud and usually sited against the trunk of a tree or large bush. Into this the female lays four to six eggs, pale blue in colour with black speckles, reminiscent of the parent's plumage. The song thrush breeding season runs from around April to October.
Provide fruit and grated cheese to attract song thrushes to the bird table, and to help them survive. Planting certain berry bushes such as cotoneaster and fruit trees like crab apple in your garden will provide winter food for song thrushes.
 

 

Seasonal Migrations

Go organic in your garden. Stopping the use of nasty insecticides and pesticides, and spreading compost on your soil will encourage the song thrush's favourite food of earthworms, slugs and snails. It will give a better, softer structure to your soil and retain more moisture that helps the song thrush to forage. Don't worry about the number of slugs and snails increasing; a song thrush will have them under control in no time.
 

 

The song thrush in your garden in the summer may not be the same song thrush that you see in the winter. Although they are resident in most of western and southern Europe, many song thrushes head for warmer climes in the winter. Much like any holiday-maker, many British thrushes head for the `Med' or Spain in winter (and who can blame them?). Wintering in Spain, however, sometimes has a high price for the beleaguered song thrush, as hundreds are caught and sold in food markets each year. The thrushes we see in wintertime are likely to be from places such as Scandinavia, arriving in Britain to escape even colder weather further east.

Feeding Habits  

The song thrush is mainly a ground feeding bird, foraging in wet and workable soil for earthworms, slugs and snails. It will also feed on insects, fruit and berries. Song thrushes will smash open snail shells on a favourite stone or obvious rock. This is called an anvil. The song thrush is the only bird to use this technique widely; a pile of smashed snail shells on a prominent stone is a sure-fire sign that you've got a resident song thrush. Blackbirds have learnt to take advantage of the song thrush's skill by waiting until the thrush has done all the hard work of smashing the snail's shell. The blackbird then swoops in, stealing the food from under the thrush's beak.

Present and Future. . . 

Song Thrush Threats 

If you're doing any work on the trees in your garden or local area, always check for bird nests, or you could be destroying a song thrush home. Planting a hedge for the next generation of song thrushes at the same time would be a great idea. When you're trimming your hedge, consider leaving one or two plantings in the hedge to grow into a tree, providing the thrush with its favourite singing perch.
 

 

The song thrush has undergone a massive decline in many places across the UK. The British population has plummeted by over 65% in the past 20 years. The reason for this dramatic decline is not fully understood, although the increase in the use of modern farming methods is a major reason. The destruction and dereliction of hedgerows, land drainage and the increased use of pesticides which kill slugs and snails have all played their part in this sad story. The destruction of its countryside habitat means that suburban and urban gardens have become some of the last refuges for the song thrush.

A Happy Ending?

All is not lost for our speckled friend. Conservationists all over the country have been made aware of the serious situation and are taking steps to prevent further decline of this well loved bird. Due to the serious threats facing the song thrush and the reduction in its population size over recent years, it has been included in the UK Biodiversity Action Plan as a national priority for action. This means that local action plans will be produced across the country, targeting the song thrush and addressing its conservation needs. The enclosed survey form will be used to help in developing Sheffield's Action Plan for song thrushes. Filling in this form and following our song thrush top tips are ways you can help to save our feathered friend.

Climatic factors may also be partly responsible. A slight increase in global temperature means hotter, dryer summers that make it difficult for the thrush to get at food in the soil. Research has shown that this particularly affects young fledglings in their first year without their parents.
