Celandine ??

I found 3 of these little Celandines growing just outside my shed door...i am having it paved this year so i must try & lift them gently and replant them..i think some of the wild flowers are prettier than the cultivated ones, If they are not Celandines, i hope someone tells me..but i think they are. They are so bright & pretty..why did they have to spring up just outside the shed, there are a four clusters of them there.
