When approached, the Curlew will sometimes just walk away and at other times will go into freeze mode and lie perfectly still.
If there is a nest or chicks involved, they will "attack" which involves spreading their wings (probably up to about 1.5m), lowering their head and making a quite loud hissing/growling noise as this guy is doing as they walk towards you.
But it's all show and no go. It's a long story but I have been on the receiving end of their "attacks" on numerous occasions.
Hopefully I can show you them nesting in the next couple of months. In case you haven't guessed, I love them.
As always, best on black
He is a beautiful bird! he certainly doesn't look impressed, but I love his spindly legs :) Sounds a bit like the plovers here that are very protective of their ground and will attack! Great shot.
