Common buzzard over the Seven Arches (Balmossie) Viaduct in Broughty Ferry. A bit later one was heard kewing loudly overhead which caused the dipper I was watching to keep glancing upwards. First time I've heard a buzzard in this area: they normally hunt silently here. 📷📸🎞️🪶 #birds #ukwildlife

I went to Geneva a few weeks ago and spoke on a panel about the nature of time for a Geneva Watch Days event. While I was there, on a lark, I entered a competition to most precisely calibrate a Swiss watch. And today I found out that I won! 😃 www.instagram.com/reel/Dd6hUTB...

A male ichneumonid seen on my first visit to Trottick Ponds in Dundee last week. No ovipositor and about 2-3 cm long so quite large for the family? I was hoping to identify it but it seems that's almost impossible for males like this! 📷📸🎞️ #bugs #ukwildlife
