How to identify

Tree Sparrows are smaller than House Sparrows, and are more active, often sticking their tails up. The Tree Sparrow has a chestnut brown head and back of the neck (rather than grey) and white cheeks and collar with a contrasting black cheek spot. They're shyer than House Sparrows in the UK, and are rarely associated with people, although in continental Europe they often nest in buildings just like House Sparrows. The UK Tree Sparrow population has suffered a severe decline, thought to be 93% between 1970 and 2008. But recent Breeding Bird Survey data is encouraging, suggesting that numbers may have started to increase, although from a very low point.

Where to see them

Tree Sparrows are birds of the countryside, but their numbers have declined significantly and they are now absent from large parts of southern England, much of Wales, parts of Northern Ireland and most of Scotland apart from the east and south.

In areas where they’re clinging on, they’re usually associated with farmland. They form small colonies in the breeding season, and then come together into larger flocks in the winter to feed in stubble fields, often mixed in with other species.

In rural towns and villages, they will sometimes visit garden feeders, and even occasionally breed in garden nest boxes. It’s easy to miss one or two Tree Sparrows in amongst a big group of House Sparrows, so remember to look out for their characteristic dark cheek spots!

Behaviour

Tree Sparrows are much more timid around people than House Sparrows, and tend to be less boisterous in general. Like House Sparrows, they’re social birds and prefer to nest and live in groups. They eat seeds from grasses and weeds, as well as cultivated grains like barley and wheat. They also eat small insects, which they feed to their young. Tree Sparrows will sometimes come to garden feeders in rural areas, particularly in winter – you might even see them mixed in with groups of House Sparrows. 

Call/song

A Tree Sparrow’s call is similar to a House Sparrow’s, but sounds more like ‘zee zee’ than a straightforward cheep. Again, the song is a continuous repeat of the call. 

Nesting

Tree Sparrows will nest anywhere with a suitable hole or crevice. They sometimes choose to nest in dense bushes or farm buildings, and will use nest boxes. They may also nest in banks and cliffs, even reusing old Sand Martin nests.

Conservation projects often put up nest boxes to help support Tree Sparrows where they are struggling.
