Who is watching who?

I usually take my zoom lens when I go choo sunsets. It is handy to get the disappearing sun looking like a fireball. So of course I did it this time too, but since I was a bit early I went to have a look at the nearby bushes and walk a bit around the fields paths. I noticed that many birds hide in them for the night so I was hoping to catch some before it gets dark.

Bingo :)





I saw this little guy jumping from one branch to another and he saw me too. And as I was trying to catch some nice photo of him that would be in focus, he was doing his best to make it harder for me.

Every time he moved to another branch it took me a while to pot him again. Sometimes he was hiding completely behind the leaves. He could have been looking for some last bits of food before the night, or a place to sleep. The bushes are thick and away from any traffic. I could hear other birds flying in and battling (probably sparrows) for a spot.





I think this is Common chiffchaff though there is another one that looks almost the same - Willow warbler. They both seem to have the lighter stripe above the eyes and some yellow on the edge of the wing and long, thin beaks.
Which one is it?

He looked at me a few times and flew to another branch.





Shook off his wings...





Stuck his butt at me. And jumped to another branch not giving me many chances to take a decent photo.





The last spot was a bit nicer - less leaves, more sun and blue sky behind. But he didn't plant to stay there longer either.
Probably didn't feel comfortable with me around.

One last look at the weird creature...





And off he went.

I really need to get myself a bigger zoom for little guys like this.
