Doves

Several species of doves are common in India. Of these, the Ring Dove, Red Collared-Dove, Little Brown Dove and the most common, Spotted Dove, share general characteristics. They are more or less of the size of common rock pigeon and frequent dry regions near cultivated land, in flocks of two or more. Often, birds of these species can be spotted together in open land, especially on babool (acacia) trees. Their calls can sound similar to a lay person, coo-coo-coooo.., but there are quite distinct variations in tone which can easily be recognized through experience.

The Ring Dove is pale gray in appearance, with a black collar on its neck.  Its tail is dark brown and lower parts of its wings have a bluish tint. Sexes are alike.
Alternate name: Eurasian Collared Dove.
Note the dove's throat bulging outwards when makes its typical call

Red Collared-Dove has distinctive light blue head parts, with rust-brown body and dark-brown tail, tinged with white feathers. The female is much duller in comparison and resembles the Ring Dove. Quite uncommon and not easily spotted.

Survival in the wild

The Mayan calendar ended on Dec 21, 2012. It did not lead to the end of the world, but may be the Mayans had something else in mind. May be the end of their calendar referred to the end of humanity, as we know it.
I refer to the grotesque act in a Delhi bus on a helpless and defenseless girl. Even death is not harsh enough punishment for the brutes responsible for such a ghastly crime.

Unending struggle
In the natural world, the struggle for life is unending and death can occur at any moment. But, nature has evolved itself in several unique ways to confront life threatening situations. When it is question of survival, we know how birds and animals react in unusual ways to defend themselves or their young ones. This defense instinct is very strong and is necessary for survival in the wild.

The skunk (or polecat) is an omnivore and when threatened can spray a potent stinking liquid, which is powerful enough to cause temporary blindness. This is apart from the nauseating stink that lingers on for hours.
The horned lizard is capable of spraying blood from its eyes. The bombardier beetle sprays a hot chemical which can cause burns on its attacker.
The Malaysian ants are able to expand their glands and squirt poison when enemies are within range. These are just few of the innumerable types of mechanisms adopted by wild creatures for their survival.

Can modern technology help?
Is there something we can learn from nature about survival in the wild? Pepper sprays and stun-guns are presently available and are being publicized as personal defense weapons. However, they are unwieldy and cannot easily be used in emergencies. C
an present technology come to the rescue by designing small and practical personal defense gadgets?

Black Shouldered Kite



This raptor (species commonly termed as birds of prey), is fairly common during the Indian winter. It can be identified from its whitish-gray upper plumage, chest and abdomen parts. There is a distinct black patch on the shoulder and around the eyes, which are blood-red. The wings appear dark gray when perched; often on telephone / electricity cables, patiently on the lookout for rodents and lizards.
They are quite easy to photograph  and can be approached without being startled by human presence. However, unless the light is good, the Fuji HS-10 does not give crisp and clear photos. May be a high end camera would give better results.

Name

Occurrence

Nannaj Wildlife Sanctuary

The short trip to Nannaj Sanctuary over a weekend was planned just after the monsoon. The weather was hot and humid. Before we set off, the organizers (Nature India) made it clear: leave your expectations, look ahead with curiosity and cherish nature.
The internal roads are narrow and navigable by SUVs; but in parts of the sanctuary, even the tempo trax found the going difficult. The region consists of open grassland and scrub forests, with undulating plains stretching as far as the eye can see. As city dwellers, we were not accustomed to see such vast expanses of grasslands and the silence made our ears ring. 
But these plains are home to Black Buck and also the Great Indian Bustard (GIB), very few of which now survive. The last census in 2011 indicated a number of just 25 birds.

No sightings of GIB were reported in the past 15 days by the forest rangers and on the first day, we returned without spotting the GIB. Of course not without spotting several more common species.
The next day, we were back. This was our last chance to spot the GIB. Visibility was excellent in the clear air and in the distance was a bird moving slowly and majestically through the tall grass. There was a cry of relief among the group; we had spotted one of the rarest birds in the world. 
How can you help? If you visit Nannaj, do buy an informative CD on the GIB from the forest office. It is available for Rs.120 only and the proceeds will help the department in their conservation efforts.
We hope the efforts of the forest department bear fruit and the bustards thrive and increase in number.
