Wheatears

I was reading an email/newsletter thingy from the BTO earlier which talked about migration being delayed/blocked by the current weather/wind direction and referred to Wheatears in particular. The weather forecast seems to largely suggest more of the same for the next ten days. I seem to remember a similar situation just a few springs back. When things did finally pick up I recall finding small groups of Wheatears in unlikely places inland where I wouldn't normally see them.
