Northerly winds block migration - last two weeks of April

The last few weeks on the Great Orme have been pretty grim with a constant flow of northerly air. The only mogrants that seem to have got through have been a few Greenland Wheatears, one or two Whitethroats, small numbers of Tree Pipits and a light passage of Crossbills some mornings. Willow Warbler numbers have started to build up this last week as has Wheatears with around 60+ of each on Monday and Tuesday this week. Hopefully the switch to warmer air will aid our migrants north.
Willow Warbler numbers have increased during the last week of April.
The first Whitethroat sang its heart out on April 25th.
