Quiztime - Winter Picnic Challenge

This time it's an OSINT quiz by @bayer_julia.
This was a very difficult quiz, as there is infinitely little information that can be read from the photos. It was a good question that reminded us that we need proper search skills, language skills, and ideas to find information efficiently.

Geolocation

Take a look at the photo.
This photo is a scene that could be found anywhere, and it was almost impossible to determine the location by image search. There is an artwork(?) in the center that looks like a netted branch. but no hits were found. You can see a sidewalk in the lower right corner, and the other clue is a tree branch, but I couldn't do it because I am not familiar with plants.

Next Geolocation

But it is not too early to give up.
During quiz time, you will find clues at the bottom of the posted tweets.
However, I only look at this when I just can't figure it out.

The tweet is below:
The landscape is very similar. And if you look up the ecology of these ducks, you should be able to get the location. I did a quick image search.
The duck's name is "Höckerschwan".
And I found that the view behind is "Eichwerder Steg".

I was able to locate the duck on Google Maps.

Re-analysis

Up to this point, I thought I had identified the location.
However, looking at other respondents' posts, apparently not.
Perhaps the location where the ducks were was near the first photo posted. If so, it should be where the terrain and trees are similar. Once again, I re-analyzed the situation here.
There is what appears to be artwork in the center of the image. First, I tracked down what this was.
I did a Google search with various thought processes here. Finally, I searched for "Berlin Haus Kunstwerk im Wald" in German and found the following site.

It seems to be an artwork called "Flämisches Haus".
