It was easy to hear their sibilant chatter (if you’ve never heard it, SoundCloud has a good recording). With their green, yellow and black colouring, they were well camouflaged so it was hard to pick them out among the Alder branches and cones. And, because of all those twigs, branches and cones, it was even harder to get photographs, which is my excuse for not getting better images of the noisy Siskins I found feeding near the Glamorgan Canal at Forest Farm Nature Reserve last week.
