"But some leaders through excessive tweeting have turned it into a jarring sound," he said.
"They seem to have no other work in a day than to make political statements for the media," the chief minister said ridiculing leaders using it as a political weapon.
"These persons are trying to monopolise even on twitter which otherwise mean sweet voice of birds that is very pleasant particularly in the morning hours," he said.
Kumar, however, did not name any politicians using twitter for making political statements.
Gujarat Chief Minister and BJP campaign committee chief Narendra Modi is among the politicians who use twitter.
Former Bihar Deputy Chief Minister Sushil Kumar Modi has also resorted to twitter to make political reactions.
Kumar, who himself holds an engineering degree, said he believes in hard work in politics and not on such "tactics".
