'Stit'? 'Tip'? 'Tit'?

From amongst the poo-eeping plovers was heard a stitting stint.

Oh look,... one of them.

Spent most of the day wading through oodles of Fox Moth caterpillars.

[Addendum (again): for those who don't do the Twitter thing, this bird was at Rhaslas Pond, Glamorganganganshireyshire.]
