"The population of little egret are believed to have increased because of milder winters, while the black-tailed
godwit, which migrate from Iceland, are thought to be increasing because of subtle changes in farming there, possibly linked to climate change."
But other species like the little egret and black-tailed
godwit are arriving in Wales in ever greater numbers.
Black-tailed
godwits are a relatively new arrival but have risen from a few hundred in the 1980s to about 6,000 now.
It is not all bad news however, with numbers of little egrets, pink-footed geese, gadwall and black-tailed
godwit all reaching record levels.
The Lindisfarne reserve is internationally important for grey plover, knot, turnstone and bar-tailed
godwit, while around 5,000 waders use the Tyne estuary with redshank, golden plover and lapwing prominent.
"And we recently saw a really beautiful black-tailed
godwit, which is probably Icelandic" he said.

The range includes some less often heard songs from the likes of the Arctic tern, yellowhammer, coal tit, and black-tailed
godwit.
There may be good reasons and bad both for and against the building of the highly controversial high-speed rail link, but the suggestion that the plan could be stalled, or even abandoned, because of the rights of the wading bird, the
godwit, surely cannot be valid?
