Garden Warbler or Greater Whitethroat in the Netherlands--Groningen (1 Viewer)

[Tom St]

Observed on 06.05.21 in Groningen.
I heard a bird singing from a small standing of bushes and trees and (with some uncertainty) IDed the song as a Garden Warbler's. When I looked at two very bad photos I took of (presumably) the same bird, it looked more like a Greater Whitethroat to me, as it seems too colourful for a Garden Warbler. But now I'm unsure if that's just due to light conditions.
As always, I am grateful for any input!

Hello Tom,
your bird seems an example of the "two birds-theory" to me.
First is a Common Whitethroat to me, rusty wing panel (with contrasting black centers of tertials), other colours and jizz excludes other similar Warblers, I exclude rarer Sylvias by distribution. I cant imagine, that light conditions can change a Garden Warbler into a Common Whitethroat
But second bird looks indeed like a Garden Warbler to me: right biuld with quite short tail for a Common Whitethroat, colours are good for a Garden Warbler. Its not an easy bird for me, and one where I didnt comment, but you heard a Garden Warbler singing out of the bush, so I assume, there was one in it.
