After a bit of a hiatus, Golden Grenades is back! Joining YOLOBirder this time is ornithologist, Jamie Dunning. Jamie is working on his PHD at Imperial College on the social lives of House Sparrows, has discovered that Puffins’ bills fluoresce and has an amateur project on the go on Twite in England. Some of us are interested in birds, but Jamie has taken it to the next level!
