Batting for bats
Bats
are something that usually inspire fear or create revulsion among all (or
most)of us. I did not really spare them much thought except on our long walks
on a disused taxi track where we used to see huge bats (recognisable due to
their typical wings) flying across the runway. More recently a group of bats
relocated to a tree outside my balcony which is when I took a keen interest.
Would they be dangerous? Will they accidentally enter my home? And so on…
Luckily they flew away before I hit the panic button.

Thus, I could not miss on a ‘bat spotting walk’ organised by Virasat Pune conducted
by Dr Vishakha Korade who has done her PhD in Bats! Here is what I
learnt.

Fruit
bats (aka Flying fox) are vegetarian and this was the species that was near my
home. (This is what I inferred from some of her answers to my queries). They
roost on tall trees with sparse foliage (we saw them hanging upside down on
Eucalyptus and Kinhai trees) and fly out at dusk and return at about 5AM. They
feed on fruits (specially of the Ficus genus) and other plant parts as well except roots and stem. The
digestion process in bats increases the chances of germination of the seeds in
the fruit they eat. These seeds are disbursed in their excreta hence the bats
are an important part of the ecosystem. They also help pollinate some plants
species (about 400 e.g. Kigelia africana, Adansonia
digitata). According to Dr Korade, while many urban people fear bats,
people in villages refer to them as Laxmi (as in the goddess)! I guess they
understand the position of bats in the ecosystem more than us city folk! Fruit
bats have fair vision and find their food etc using their eyesight and
olfaction.Contrary to belief, fruit bats do not use eco-location.

insectivorous Evening bats (called पाकोळया
in Marathi) produce twins about thrice a year but they are lost to predation
and the total number often does not increase. These bats look like swifts and
can be seen about 15 minutes after sunset. They may share a shelter with swifts
too. Evening bats use eco-location to find their food.

There is a species called Vampire bats that feed on blood (usually of cattle). They secrete an anticoagulant when they bite the animals and then feed on it. These can also regurgitate the ingested material to feed young ones left behind or those unable to fly out. There is a type of ‘false vampire bat’ that is found in Asia.
Bats
have a weak pelvic girdle and lower limb muscles and do not ‘stand’ on legs like
humans. Being mammals, they give birth to live young ones. Fruit bats produce
one offspring every year (after about a two month gestation). The young ones may be carried on the bellies for some time. Bats are a
reservoir of many types of virus and may be carriers of Rabies, Ebola. They usually
are not dangerous to humans but may spread disease if people consume plant
produce contaminate with bat fluids (e.g. toddy collected from trees). Their
bodies are geared for an upside down life. Here is a link to some info about the bodies of bats.

In
recent times, bats may have gained some popularity due to the popular book
series by Stephenie Meyer. However I was pleasantly surprised at this session to
see kids ask several intelligent questions. I guess India does have a bright
future, provided they stay and work here of course not fly off to foreign
lands…

The number of fruit bats in the colony we saw is dwindling which can be a cause for alarm as an important member of the ecosystem will be lost. Loss of their habitat could be a reason. Indiscrimiate cutting of trees has to be stopped.
Its important to keep learning something new as its a big wide world and we would only have skimmed the surface!
What have you learned recently?

The city had become a grey, white concrete
glass jungle. Green was now an artificial colour in books and paints. He looked
hopefully at the assortment of seeds in the magician’s hands. Maybe he could do
the impossible. Get the seeds to germinate. Bring green back to life.

From Fruit to Kernel
Cashews are coveted as dry fruits and are commonly added to gravies and sweets in Indian cuisine. I did know that the nuts grow outside the fruit but beyond that I had given no deep thought about its journey from the farm to the table. It is quite an arduous route, one that I recently witnessed.
Any guesses? That’s right, at a cashew factory!
The cashew tree is Anacardium occidentale that belongs to the Anacardiaceae (Mango) family. Its fruit is an accessory fruit (or false fruit) that has a pear shaped structure called cashew apple and at its end is a kidney shaped drupe. The drupe contains one seed which is the cashew. The apple is used to make Feni and the drupe is processed to make the cashews we know.
There was a pile of drupes at the Kamat Cashew Factory at Sawantwadi. They were creamy yellow coloured and the shell was quite hard to touch. The proprietor was enthusiastic and gladly guided us through his establishment with a running explanation.

So does one simply break open the shell to get the nuts? No.. Far from it. These drupes undergo their first roasting over steam to mark the start of processing.
 |
| Following first roasting |
The drupes are put into special machines that cut open the hard outer shell. Earlier, the cutting was done manually which did horrible things to the hands of the ladies doing this delicate job. The machine we saw, picked up one drupe at a time, split the cover and the broken cover and kernel were ejected out. This shell has toxic substances (which cause terrible reactions when in contact with skin) and our guide cautioned us against touching them.

| Shells and kernels |
Shells are
sold to paint making companies and the kernels are roasted for a second
time. The resultant product is covered in a dry thin brown skin which may be
removed by further processing. Some kernels are sold with these brown
skins itself.
The kernels are now ready for sorting. This process is done by skilled hands and eyes that segregate the nuts based on their size and colour. I witnessed one lady who sat at a ‘console’ (see image below) and went about deftly throwing cashews in separate containers without even looking up from the pile in front of her.
What Aim! There was no scope for mistakes.

| Separated and Packed |
Grading cashew kernels is important as the bigger ones are priced higher. The broken pieces are sold as such and are ideal for adding to cakes or sauces. At a cashew shop one finds them graded asW150, W180. W210, W240 and so on. W refers to whole (B will stand for broken; S for split etc) and the digits are number of kernels per pound. So W150 means there would be 150 kernels per pound. There is a category called SW which means Scorched Wholes where the kernels are scorched or marginally darkened due to excessive roasting. Here is a link with some info about cashew grades.

The entire process may take a week or more. I was told that despite widespread cultivation of cashews in the coastal regions, many factories process nuts imported from South America (they are cheaper despite travelling across the oceans) compared to the local produce. Ironic isn’t it?
Other factories may have different processing methods but the general idea is to dry, crack open the drupes, roast and then segregate them. Some are further processed into salted cashews or flavoured with other spices.
Here another two images from the factory.

Point to note: There are several cashew factories in Goa but not all welcome visitors. We took a chance with this one and got lucky.
Even at this stage in life, I have learnt something new. Learning never ends… We just need to have an open and curious mind…
Ciao folks!
