Today I received an e-mail and they said this.

It is very similar to our saying "bir taşla iki kuş vurmak".

I wonder how old (and wide) is this usage in English? I just wonder if it may have been entered to English from Turkish.

it is a very popular saying in english.

i got this reference from this website (http://www.phrases.org.uk/bulletin_board/28/messages/640.html):

KILL TWO BIRDS WITH ONE STONE - "Achieve two objectives with a single effort. It would be remarkable indeed if someone slinging a stone at a bird got one bird, let alone two. Ovid had a similar expression in L*tin nearly 2,000 years ago. Related phrases were in English and French literature by the 16th century. Thomas Hobbes used the modern version in a work on liberty in 1656: 'T. H. thinks to kill two birds with one stone, and satisfy two arguments with one answer.'" "Dictionary of Cliches" by James Rogers (Wings Books, Originally New York: Facts on File Publications, 1985).

I am surprised as well

we use this saying in arabic too,
when someone do two same time

We use this saying in spanish too, to illustrate that you can simplify the way to make or do somenthing. In my country, Argentina, is also very popular.

We say it in Dutch too, but we say 'Two flies with one hit'. Twee vliegen in 1 klap.

Nothing less than two elephants with one hit can qualify, in my hometown. Three elephants with one hit is considered a minor success.

Sometimes in Turkish, funny guys say "Bir taşla kuş katliamı yapmak"
"To make a megadeath of birds by one stone"

In spanish it is "Matar dos pajaros de un tiro"
Translation : "To kill two birds with one shot"
Yes, very similar!!!
