Been enjoying the photos of the megas on Cape Clear (Solitary Sand and Northern Waterthrush on the same puddle!). Must be very exciting to be there now but just wondering how coincidental it is or if there's any pattern of occurrence. Is that a random weather event that dropped a bunch of nearctic migrants specifically on to Cape Clear or was it a wider dispersal and Irish birders are the only ones out in the field finding them and local birders in Cornwall, Scilly and Hebrides are asleep?
I keep hearing from the weather experts that the la nina cycle is helping to make this a wet summer and that there are echos to 1985 and 1989. 1985 became a big hurricane year with direct hits to the US mainland. 2008 is also shaping up to be above average (think the stats are 85% above average). Now, many of us old farts will remember how autumn 1985 turned out for nearctic vagrants and Scilly was awash with goodies.
The Cape Clear waterthrush beat the previous early record by 2 days (Scilly in 1989). Coincidentally, 1989 also scored an August Solitary Sandpiper but the rest of the autumn was a wash-out for nearctic migrants, so don't count on the rest of the autumn being as good.
