House Sparrow



The Indian House Sparrow (Passer Domesticus Indicus) belongs to the Passeridae family and is common in urban areas and human settlements. They are small passerines with short and heavy bills and strong legs, who hop to move about on the ground. They do not possess a true song and instead communicate with chirps. The female is dull and pale in comparison to the male. 

This bird, which is the most common avian in India, is known as Adaikalang Kuruvi in Tamil. Its size is the same as the Bulbul.

Male of species


The plumage of the House Sparrow is mostly different shades of grey and brown. The female is mostly buff above and below, while the male has boldly coloured head markings, a reddish back, and grey underparts. The male also has a dark grey crown from the top of its bill to its back, and chestnut brown flanking its crown on the sides of its head. The female has no black markings or grey crown. Its upperparts and head are brown with darker streaks around the mantle and a distinct pale supercilium. Its underparts are pale grey-brown. The female's bill is brownish-grey, and becomes darker in breeding plumage, approaching the black of the male's bill.

This bird is very social. It is gregarious at all seasons when feeding, often forming flocks with other types of bird. It roosts communally, and its nests are usually grouped together in clumps, and it engages in social activities such as dust and water bathing, and "social singing", in which birds call together in bushes.

Nesting season lasts practically throughout the year. With the most favoured months varying with locality. Its nest is a collection of straw, rubbish and feathers in a hole in ceiling, niche in a wall, an inverted lamp shade—and every conceivable site, within or without any occupied building. Its clutch usually ranges from 3 to 5 eggs, that are pale greenish white stippled and blotched with brown. Several successive broods are often raised.

The House Sparrow is monogamous with both the male and female helping in nesting activities, which are normally found in small crevices of traditional Indian homes, ground, banks and sometimes in trees.

The House Sparrow is believed to have been closely associated with people for around 10,000 years. This bird is inseparable from human habitations. It is a confirmed hanger-on with man, in hills and plains alike, whether in a bustling noisy city or outlying forest hamlet.






It is an omnivore and its food is comprised of; grain, insects, fruit buds, flower nectar and kitchen scraps. This bird sometimes collects in enormous flocks and does damage to ripening crops and in market gardens. In common with many other birds, the House Sparrow requires grit to digest the hard seeds it eats. Grit can be either stone, often grains of masonry, or the shells of eggs or snails; oblong and rough grains are preferred.

The House Sparrow 

“A bit of cereal, the right kind of garden hedge or even just a nesting box are all that it will take to protect a bird that lives alongside humans but is fast disappearing. 

In the midst of much informed and universal concern about the future of the house sparrow (Passer domesticus), one of man’s oldest living commensals, there is a ray of hope yet. For, returning home on the first sun-drenched mid-morning of January 2013, I experienced the heart-stopping moment of seeing 23 house sparrows, basking in the warmth of the sun! Given a conducive habitat, all other side effects of modern day life-styles notwithstanding, the house sparrow should be the last of all to wander off the living planet. 

The house sparrow is a sober-looking bird with a ubiquitous spread — from Leh in the North to Cape Comorin in the South and from the Somnath Temple in the West to the Camorta Island in the East. With that kind of a presence, we should be able to spot them anywhere. Ornithologist Salim Ali had labelled them as “man’s hanger-on” for they are known to enter homes nonchalantly, chattering non-stop as they set about arranging their personal living comfort by adding heaps of straw to any potential nest-site, quite unmindful of the householder’s presence. 

New lifestyles to blame 
But today, most Indians would perhaps know this bird only through photographs. Not even two out of 10 may be able to lay claim to having seen the bird in the outdoors. So why do so few of us encounter the bird despite its worldwide spread? As the bird lives only among humans, it’s not about disappearing forests, but about the pollution around us, including from communication towers, the use of steel and glass in our buildings that has reduced the availability of nesting sites and food, and, where there are gardens, the partiality for exotic rather than indigenous vegetation. 

This shift to new lifestyles, even in rural communities, is at severe conflict with the house sparrow’s basic existential needs. In China, the house sparrow was exterminated by about the end of the 1960s after being declared the number one crop pest. On the other hand, that very “pest number one” became the angel of progress in America and Australia where it was not native but consciously introduced for pest control in agriculture, to cut down the reliance on chemical alternatives. With time, the house sparrow came to be equivocally feted in both continents. Today, the bird figures high in their avian literature and is much cherished. 

Coming back to the large number of resident house sparrows at our home in Chandigarh, there are two contributing factors. One is that my wife has always spread abundant food on the rooftop, every morning. Coupled with that is the availability of secure roosting and nesting niches by way of thick, tall hedges on two sides of the house. Of course, there is natural predation of fledglings by crows and by an odd Shikra (a hawk sub-species) but the house sparrow is a sturdy breeder raising three broods of two to five chicks, thrice each year. So the population does not merely “hold” at the optimum survival figure for the given area at our home but also feeds the neighbourhood. As simple as that! 

No description of the bird will be complete without a mention of the strong streak of tenacity in its character. And here I can do no better than quote the master, Edward Hamilton Aitken (born in Satara, Maharashtra, in the mid-19th century to Scottish parents) from his book “Common Birds of Bombay” (1900): “And when a Sparrow makes up its mind nothing will unmake it except the annihilation of that Sparrow. Its faithful spouse is always, and very strongly, of the same mind. So they set to work to make a hole in the corner of the ceiling-cloth and they tear and tug with an energy which leaves no room for failure. Then they begin to fetch hay and the quantities which a couple will carry in a day is miraculous…. I declare solemnly that you might have fed a horse on the hay which I removed daily as most of it tumbled down….” 

Much like most bird species the house sparrow is highly adaptable. Even though its traditional wilderness has been usurped and its living niche inside man’s once mud-and-thatch dwelling replaced with glass and concrete, the house sparrow could well be the last on this living-planet if mankind were to spare just one hundredth of its cereal intake for the bird and make space for it around homes, where possible by planting indigenous hedges, and if there is no garden, by simply providing a nesting box. That’s not too much to ask.”

There seem to be an equal number of friends and foes to the House Sparrow. Some see the birds' value in ecology as a natural answer to pest reduction, and others, more so in the Western World, view them as pests to be eliminated. For those "friends" to the House Sparrow, here is a nice link about how to purchase and order small, inexpensive homes for the House Sparrow.

Ways to deal with Bully Birds



Bully birds include Crows, Blackbirds, Pigeons, Starlings, Mynahs and House Sparrows. These hungry avians are often attracted to a yard by cheap wild birdseed mix or suet that's made available on the ground or in easy-access feeders. 

Bully birds are a nuisance, but you can take some simple steps to prevent the larger birds from dominating feeders—thus allowing less aggressive birds to get close and feed. Here’s how: 


1. Modern Feeders: As bully birds are generally larger than most of the more “desirable” feeder birds, look for a rubber-coated mesh that surrounds traditional tube, suet and tray feeders. It allows smaller birds to pass through and enter the feeding chamber. Bullies such as Blackbirds, Pigeons, Crows and Mynahs can’t squeeze through. 


The photographs in this posting are of different styles of Bird Feeders readily available, if not at local shops here at Tiruvannamalai, then easily ordered and purchased online.

2. Take cover: Many bully birds are known for their love of suet cakes, and it is not unusual for them to eat a whole cake in a single day. To prevent them taking advantage, hang suet feeder under a domed squirrel baffle or buy a Starling-proof suet feeder, which allows birds access to food only from beneath the feeder. Starlings are reluctant to go under any sort of cover. 



Impossible for larger birds to perch at


3. Catch seeds: Many find that foiling bullies at feeders isn’t quite enough because they often eat the food that the other birds drop on the ground. To solve this problem, place a large container under a hanging feeder. Bully birds are unlikely to fly into the container to get discarded seed.

4. Be selective: Selective feeding is another way to control the kinds of birds that eat at your feeders. Generally, bully birds prefer bread, corn millet, wheat and sunflower seeds and do not like safflower or nyjer (thistle) seeds. By offering just selective seeds—and not wild bird seed mixes—only smaller less aggressive birds will come to the feeders to eat. 

If you feel tube feeders with with only nyjer seed (thistle) and safflower seeds in hopper or tray feeders, such birds as Crows and Blackbirds will generally look elsewhere for the foods they like.

5. Aid acrobats: Bully species usually require a perch to hold onto while eating, but most finches and many other small feeder birds can eat without perching at food ports. Finches can cling to the sides of a tube feeder and eat all day long. Bullies can’t. Some commercial tube feeders have perches above the food ports, where the birds have to stretch downward to feed—something that bully birds can’t do either.

6. Use bottles: Thwart suet-eating bullies at a cage like feeder by inserting a long perch that extends out both sides, placing a small soda bottle over each end. When a bully lands on a soda bottle, the weighty visitor rolls off the perch. Smaller birds are too light to roll off the bottles while feeding, or they can cling to the wire cage.

7. Offer alternatives: A male hummingbird is often aggressive and protective of a sugar-water feeder that he considers his own. Only “his females” and their young are allowed to feed undisturbed. The simple solution is to set up an additional sugar-water feeder on another side of your house, out of sight of the other male’s domain. 


Happy, thriving birds at feeder


8. Buy weights: Look for a bird feeder that has a weighted perch or treadle. When larger, heavier birds land on a treadle, it drops down over the bird food. (This device works against squirrels, too.) Lightweight birds can reach the food because the treadle does not drop down when they perch. 



When this big, NOTHING is going to keep you out!



Easy ways to discourage bullying birds and to make a haven for small indigenous birds: 

Keep less open, grassed areas in your garden. This type of open environment tends to encourage the bigger birds. For smaller birds, set aside at least a part of your garden and allow them some territory of their own. 

Create a garden with dense plants. The creation of denser foliage and the reduction of grassed areas will create a safe haven for smaller birds. Grow thickets as they are ideal hiding places and homes for smaller birds. Experiment with thick rows of shrubs rather than just having one or two here and there.
