Hazel Catkins.

At least, I'm pretty sure they are.

It was a drab day, so I blipped this specimen that I plucked from the tree a few days ago (just in case). When I'd finished I accidentally knocked a load of pollen off, it was surprisingly heavy, dropping straight down onto the table-top. Being a wind pollinated plant, I had assumed that it would slowly drift down; anyway, it gave me an idea for a future blip, if I can find some unripe catkins.
