I should not make a single step without camera, least of all go for bread shopping on Saturday morning without camera - the most interesting things happen then. Unfortunately I did not take my camera yesterday morning, so I just can tell you of what I saw yesterday while coming back.
This squirrel (photo from earlier)
lives here and I saw it running on the parking place between my building and the next, which is the building where the crazy woodpecker made all the holes (photo also from earlier)
The squirrel first hopped on a bush in front of the building and from there on to the building and it climbed up on the corner! I waited for it to return down but it went up all the way to the hole you can see in the photo above and went in.
By the way, last summer a great tit raised her young in this very hole. This year I saw already various tits and also the woodpecker testing this one. For them it might be advisable not to use this one, if the squirrel can reach it that easily.
Unfortunately I did not get to see what happened next, it was most probably already out when I reached up and had a look out from my balcony, this time with the camera ready.
