Fly appreciation post. For a long time my favourite taxon has been diptera or flies, mostly because of the immense variation. Here are 4 of my favourite recent fly shots. 1. Ringed Pixie 2. Antlered flutter fly 3. Eutreta noveboracensis 4. Hystricia abrupta 🌿📷🦋 #inverts #insects #wildlife

I heard Blue jays calling and investigated to see what was bothering them. Turns out a Gray ratsnake had climbed their tree. Gray rats are shockingly adept climbers and can often be found in tree branches. 🐍📷🌿

I had an incredible once in a lifetime experience when a Willow Ptarmigan came walking up to me. I hid behind a tree about 50 feet away to keep some distance and then it ran up to me. Never been so scared I'd flush a bird. I stood still as a statue until he left. 📷🪶🌿

If I had to pick a favourite bird group it would probably be gulls. And if I had to pick a favourite gull, it would be hard not to choose the Glaucous gull. I was lucky to run into this 1st year bird this morning 🪶🌿📷

A Long-eared owl I spotted while on my finch hunt. I find Long-eared owls tend to rest too close to trails, so when I see them I try to leave the area so as not to disturb them. This owl was being mobbed by smaller birds which explains why he was awake and alert during the day. 🌿🪶📷

Not every day you run into a King Eider. This male is about a year out from his full adult plumage. Next year his bill will protrude to give a square headed look and he'll start to get green coloration around the eye. 🌿🪶📷

One of the worst parts of winter is not having a lot of daylight, this means I sometimes have to do my nature watching in my office. Last week I found this Western conifer seed bug with Tachinid fly eggs (likely from the genus Phasiinae). #insects 🌿🪰
