The 31-year old striker had two impressive seasons with Killie after joining from Sheffield Wednesday in the summer of 2011 but was transferred to Hibs on Friday and he suggests it was a little out of the blue.
"(Kilmarnock chairman) Michael Johnston was happy to let me go for free and (Hibs manager) Pat Fenlon was willing to take me," he said.
"I was a bit surprised. I still had a year left on my contract. But obviously the new manager (Allan Johnston) has come in and maybe he wants to bring in his own sort of players.
"I don't know what their reasoning was. I just know they were willing to let me go for free. I suppose nothing should surprise you when a new manager comes in."
