Wraysbury GP - 19th August 2021

 Two weeks since we've been to this site. The vegetation continues to grow and it's no exaggeration to say that thistles in some areas are at my head height. We've noticed this is forcing birds to fly at a higher than usual height and a lot of birds seem to be going over the nets.

We took a decent first round, after which the site seemed a lot quieter. We are already seeing a drop in  Garden Warbler as expected, and from experience, Whitethroat will be the next species to reduce in numbers.

4M and our only Whitethroat adult today and still finishing primary moult. 5 to the 8, 4 to the 1, 0 to the 1. No surprise at F0M1 that it's not started fat deposition while renewing flight feathers.

A juvenile Whitethroat at F3M2 and 16.1g that we expect to depart very soon. 
Post juvenile moult completed, now fuelling up for the migration.
