Over the weekend, I took part in the first-ever Brussels edition of iNaturalist's City Nature Challenge. The idea is to make as many documented observations of plants and animals as possible and Brussels is the only city in Belgium participating this year. I decided to do my regular route around my Brussels patch but it was quite a challenge switching from my usual routine of trying to see things to trying to photograph them all, with common but skulky species such as Wren taking up much more time than I would usually spend on them. In the end, I managed to photograph 38 species (31 birds, 3 butterflies, 2 mammals, 1 plant and 1 snail), including my first Swifts of the year which appeared over my balcony on Sunday morning.
