Hello all. I am also struggling on my last four in this quiz.
No. 15 - Tie up alongside (7) - Thinking Moorhen but can't see the Hen bit.
No. 33 - Crawling up the canopy (11) - Some sort of Creeper?
No. 36 - Wash road marker singing (6.7) - Think it's Warbler of some sort. Have seen Willow Warbler but can't see how Willow fits.
and lastly No.74 - Sounds like you're not feeling too good (4) - Thinking Rook but don't think that's right.
Thank you.
36. Someone has posted that there are willow trees along Welney Wash Road so that's where the willow bit comes from. Not being local didn't know that. No. 15 I'm thinking moorhen too because can't find anything else to fit.
