The bird, called Stanley, is a resident of World of Wings Birds of Prey Centre in Cumbernauld.
He was reported missing on Sunday afternoon after reportedly being scared off by some gulls.
Staff at the centre issued a statement saying: “During a flying session earlier today, Stanley our Stork got mobbed by some gulls and got chased off. He was last seen flying in east of the centre. Unfortunately, we have not been able to pick up a signal from his radio telemetry in a while and due to the wind picking up he could travel quite a distance or have landed somewhere to shelter.
“Description – Stanley is around the size of a heron, is mainly white in colour with a distinctive black stripe running from wingtip to wingtip. He also has a long, thin, pointed orange beak and long orange legs. He also has a tracker on his tail.”
Anyone who spots Stanley is urged not to approach him and to contact the centre either through its Facebook page of on 07546252615.
Nearby Tannoch Stables also issued a statement to its members asking them to look out for Stanley.
It read: “When out hacking or walking around Palacerigg Country Park, could you look out for Stanley the stork please. He got caught in the wind and has been lost from World of Wings Bird of Prey Centre. They lost the tracker signal over Palacerigg. He is about 3ft tall. Many thanks.”
