I can imagine a couple of bird watchers who become excited when they sight puffins on Pembrokeshire’s Ramsey Island.   There haven’t been puffins on the island since the 1890s when they were killed off by rats.  The rats are gone now, but the only puffins on the island are plastic decoys, installed on the cliffs  in hopes of luring real puffins back to their former home.   Apparently the use of plastic decoys has been successful on other islands, so the folks on Ramsey are hoping that  their plastic puffins will do as well.
