Since Chris T posted an image of the juvenile march harrier at Glaslyn a few days ago, I've been thinking.
For years, I used to see a female wintering just to the north of Porthmadog when I used to live in the area. For the last few summers we've regularly seen a female at Cors Dyfi too, and even managed to photograph one this season with the osprey nest cams.
Is this species under-recorded in Wales? By definition, they nest and frequent marshy, wet areas where not many people live. Add on top of that, that mid Wales is one of the less populated areas in England and Wales, and you have a recipe for under recording.
Below are a couple of images of a marsh harrier in Scotland last week - the ospreys took no notice until she came too close and the male shot off after her. Ospreys and marsh harriers are often seen together in healthy ecosystems, often breeding near wet, marshy areas.
Three pairs of breeding ospreys in Wales now, but still no marsh harriers - there 400 pairs breeding in England. It's not a matter of if hopefully, but when, in Wales.
