Just had a quick look on my way back from the tip.
No waterfowl seen on main dam, did not check upper due to work being done on footpath.
Willow Warbler, Blackcap and Chaffinch most notable singing.
3M 1F Tufted Duck on dam.
1 adult Canada Goose just visible on far bank, may have been others present, the banks are very overgrown these days.
Nothing visible on fields opposite apart from a couple of Woodpigeon, again very overgrown compared with past years.
Also, I normally park opposite the Shepherds Rest and walk to Longfield Dam, but there were over a dozen cars there and along the road. I believe at weekends it has become a major issue, with large numbers parking to walk up to the "beach" at Gaddings Dam. What effect all this might be having on the wildlife is up for debate, I suppose.
Finally, in Todmorden I saw the first of no doubt many juvenile Jackdaws today. I haven't seen any obvious juvenile Grey Wagtail again, although regular adult sightings, and as far as I've seen there have not been any Mallard chicks on the Calder in the town centre this year.
