Ethology is derived from two Greek words: "ethos", meaning 
character, or custom; and "logos", meaning study.

In this post we will see another book in the series Science For Everyone. This one is titled Ethology – What Animals Do and Why? by Igor Akimushkin.

About the Book:

Igor Akimushkin is widely known in the USSR as a popularizer of biology. He is the author of over sixty science fiction books, including some for children, and many have been translated into the languages of peoples of the USSR and foreign languages. They describe the wonderful world of nature, awaken us to the marvels that exist just beyond the thresholds of our own homes, and explain the latest discoveries in biology. The series called “The Animal World” is particularly interesting having been awarded first Prize at a national contest held annually in the Soviet Union by the “Znaniye” society.

This book was translated from the Russian by Pyotr Aleinikov and first published by Mir Publishers in 1988.

This book was on the wanted list of Science for Everyone titles for quite some time.
Finally we got this comment from Sanjeev some days back:

Think it took me 6 hours today. 3 hours to scan (learnt that 
“custom scan area” works best on on my canon lide 90, since 
it does not have to traverse the whole length), then “Scantailor”,
which is pure magic, but a bit of work since I needed to revisit
each of 290+ pages in each of the 3 steps.. then adobe acrobat 
for combining the tiffs into pdf and adding OCR  Now where do 
I upload it?

and then

I have uploaded it here  Feel free to upload elsewhere too. Thanks!

All credits for making this book available to us goes to Sanjeev. My many thanks to him for this!!!
