A couple of twitchers hope to break the record for the number of different bird species spotted in a calendar year.
Alan Davies and Ruth Miller are spreading their wings worldwide
Alan Davies, 46, and Ruth Miller, 43, have sold their home in Conwy and are flying to Arizona in the United States on the first leg of their world trip.
They will visit countries such as Ecuador, Malaysia and Finland to try to see more than 4,000 different types of birds and claim a world record.
The pair left their jobs with the Royal Society for the Protection of Birds.
The couple said they loved both travelling and birdwatching.
"We've got that travel lust," he said.
"We want to get out there and see new places and exciting birds in fantastic scenery and that's what we intend to do.
They have sold everything in preparation for the trip.
It means they are starting out with the clothes they are wearing, passports, binoculars and a credit card.
But even though they have planned their route, they will be relying on local bird watchers around the world.
They will also take cameras with them to keep photographic records of the birds they saw along the way.
Alan Davies worked at the RSPB reserve at Llandudno Junction
Among the finds they hope to spot is the harpy eagle, a large bird of prey which exists in the Amazonian forest in Brazil.
"What we're looking for is the number of species," she said.
"You can see a good number of birds at the RSPB reserve (at Llandudno Junction) but we're aiming to break the world record for the number of bird species seen in a single calendar year.
"And to do that we've got to go where there the birds are.
"And that means going round the world," she added.
It is believed the present world record number seen in a calendar year is 3,662 birds.
