Bird Quiz

[Lars2017]

I've completed a Birds Quiz but I'm just unsure about a couple can you confirm or put me right.
1) Rambling (anag) Im assuming it's Brambling but it's spelt wrong?
2) The clue is Chicken tied up in the River, I thought Moorhen but also toyed with Waterhen.
3) Long-legged walker - I went with Stilt?
4)Warlike General - I put Hawk but wasn't sure.

Moorhen is definitely correct - though using 'tied' up isn't a good cryptic clue.
