"I worked in the party for last 20 years, but did not get importance in the Congress," Behera told reporters.
The Congress legislator claimed that he had raised certain issues with the OPCC president, but they were "ignored".
The Salipur MLA had earlier given indication about his move when he stopped using party flag and banners during a recent padyatra in his constituency.
Asked whether he will join the BJD, Behera said: "I will take a decision after consulting my supporters and seniors in Salipur."
He said that he will take a decision in this regard within a day or two.
With Behera's resignation, the number of the Congress MLAs in the 147-member Odisha Assembly has come down to 11.
Of the 16 Congress MLAs elected in 2014 elections, four have resigned from the party and one Subal Sahu from Bijepur in Baragarh district had passed away.
Simultaneous polling will be held in Odisha for its 21 Lok Sabha seats and 147 Assembly constituencies in four phases on April 11, 18, 23 and 29.
