H is for House Sparrow

House Sparrow (Passer domesticus)

If I could pick a bird that means the most to me, it would be the house sparrow. Part of daily life at home was  to wake up to the discordant chirrups of the clan in the hedgerow, watch  them streaming to and from the feeder in the chicken  coup (never mind the bird table!) ,see them take dust baths on the garden path and hear them tumble shouting through the bushes in a dominance squabble .  Sparrows were the mainstay of our garden before the fancy finches arrived when sunflower hearts were provided, and thankfully it continues to support a strong population.

The house sparrow is a typical “little brown job” for birdwatchers, particularly the more uniform female. But look closer and you will see intricacy in their plumage with a surprisingly rich palette of browns and greys.  The male sports a grey cap trimmed with reddish brown, and a black beak and eye surround which give him a haughty expression. His most distinctive feature is a scruffy black bib. The size of this correlates with his fighting ability, so signals his dominance to other males and prospective mates. The female is a more modest dusty brown with a dark eye stripe and pale brow and her beak is yellowish. Juveniles are similar to females, but dumpier and with yellow “lips” around the bill that disappear with age.

Though they have a strong beak designed for seed-eating, sparrows are omnivorous (feeding off plant and animal matter) and take a variety of foods. They will nip the buds and flowers of plants, but also pick off insects such as ants, aphids and caterpillars. Sometimes they dart out of bushes, or comically hop along rooftops after flying insects. Importantly, young sparrows require protein-rich insect food in their early life.

The sparrow’s prolific breeding habits are part of their success. They may have 3 broods a year, and may show their uglier side in order to achieve this. Affairs, infanticide (by both males and females) and even eviction of other bird species, such as house martins, swallows and tits from their nests are all common practice.  Whilst such behaviour clashes with human values, it is simply a part of the sparrow’s ecology. They have also been helped in their world conquest by humans, who introduced them to America and New Zealand making them the World’s most widespread bird.

Few other British birds have such an intimate association with humans. It is difficult to imagine this species existing without us, occurring as it does around farms, industrial buildings and of course houses and residential areas whilst being largely absent from the wider countryside*. Their name ‘domesticus’ refers to their association with houses. They are such a part of British life that this line-up wouldn’t be complete without them.  It is therefore surprising the sparrow is not doing so well in modern times.

The sparrow’s history is thus intertwined with our own. As a flocking bird with a taste for grain, it was arable farmer’s enemy number one . A price was put on their heads and they were heavily persecuted. They were even eaten, especially their eggs which provided a free, to people who placed nest boxes on their home fronts to harvest them.

Then, in the 1800’s when farmhands moved to the cities in search of work, the sparrow was there too.  Feeding off spilt grain in horse fodder, the insects in their manure and human scraps and sharing the tenements as roosts and nests, they provided little reminders of home to many, whose attitudes changed towards these common birds.

The movement towards feeding wild birds in the Victorian era was eagerly received by the sparrow. They became a fixture of urban parks, where they grew tame and delighted visitors by feeding straight from their hands, a pastime within living memory.

House sparrows continued as a constant among the British public, but then, in the 1990’s a drastic  decline of this super-common bird raised surprise and alarm. In 2002, the RSPB declared it a red status species due to this rapid drop in numbers.

This was part of a decline in several phases since the 1920’s, caused by different factors in urban and rural areas. Rural sparrows became a victim of increased agricultural efficiency during and after the Second World War which affected all farmland wildlife. The reduction in arable weeds, intensified grazing and shift from ecologically diverse hay meadows to plain, grassy silage reduced the natural seed and insect foods in summer, whilst improvements in harvesting and storage meant less spilt grain as a winter food source. Hedgerows were removed, taking with them the sparrow’s roosts and shelter. Cities provided some refuge from these impacts, but the changes in transport and in urban planning, increased tidiness of gardens, and even blocking up of building eaves to discourage them all had their impacts.

But there is still hope for the house sparrow. They aren’t declining in all British cities, and numbers are actually increasing in Wales and Scotland. So perhaps the homage to J.J. Audobon’s illustration of the now extinct Carolina parakeet ( Conuropsis carolinensis) isn’t so appropriate. 

You can help conserve house sparrows in your garden by providing plenty of bushes or a hedgerow (preferably a native species) as cover habitat, putting up sparrow nest boxes (preferably several individual boxes close together, as they dislike the disturbance caused by commonly marketed multi-chamber boxes)  and of course feeding and watering the birds. They are not fussy. Mixed seed, sunflower hearts, peanuts and suet will all be appreciated.  

With the help of ordinary townspeople, the sparrow may still cling on. I hope it does.  Britain would be a much poorer place without this common and characterful bird.

House sparrows are not the only sparrow in the British Isles. Their rarer, more strictly rural cousin, the Tree sparrow (Passer montanus), has an entirely chestnut cap, a black cheek patch and near-white (as opposed to grey) underparts. Confusingly, the dunnock (Prunella modularis) is commonly called the ‘hedge sparrow’, and though the plumage is remarkably similar to the female house sparrow, they are unrelated. Their name is a relic from a time when ‘sparrow’ applied to any small, brown bird. In relation to this, in the sparrow’s scientific name passer we see the origin of ‘passerines’, the entire group of perching birds.
