Interested to read your posts - I tend to agree with you both - terrific potential but from my 2 visits seemingly very highly disturbed habitat. The top reservoir in particular has potential to be really good - if (and it is a big and highly unlikely if) it could be fenced off and humans and dogs kept out!! Both reservoirs have small areas of fringing reedbeds which if allowed to expand could be good for warblers, buntings etc. There can't be too many areas of Oldham which have any reedbed type habitat?
Visit this a.m. - Little Grebe still present - caught two small fish and ate then unharassed
Also - a male Great Spotted Woodpecker, terrific views of a Green Woodpecker - which spent the whole morning yaffling loudly. 2 Jays, 2 Coal Tits, a pair of Bullfinches, 1 Kestrel, 1 singing Goldcrest, 1 Song Thrush singing and giving a zig-zagging type display flight near the visitors centre. A small party of Siskins could be heard (but not seen) from the woodland fringing the upper reservoir.
Will definitely return in May to see what warblers, chats etc turn up!
re: Strinesdale reservoirs. It's my WeBs survey site/Atlas tetrad and does quite well despite getting a lot of disturbance from local kids. In fact the Medlock Valley wardens, based in the offices at the old waterworks by the bottom res., had to take a tern/gull/duck nesting/resting raft off the top res because so many kids were swimming out to use it as a diving platform!. It is certainly much more productive than it was when I first visited it back in 1975 while it was still in use as a reservoir. The little owls bred on a regular basis and I think there have been breeding redstarts in the surrounding woods on a couple of occasions. Typically, the best ducks of the winter turn up when I'm at the other end of the County. But it was worth it for the cetti's -and we did see 11 goosander(2 drakes & 9 ducks) at Pennington
Bill visited this site myself a few weeks ago,parked in the new car park near the visitor centre appears to be a good habitat, and looks good for spring migration.
Visited this area of Oldham for the first time ever today - despite having lived in the area for 20+ years! Really will have to try and get out a bit more
On the upper reservoir - 1 Little Grebe, 2 redhead Goosanders and a pair of Tufted Duck. 170+ Black-headed Gulls, 2 Herring Gull, 1 Lesser Black-backed Gull and 1 Common Gull. The poor Little Grebe was followed around by a single predatory Black-headed Gull waiting for an opportunity to pinch any food off it - the miserable sod!
1 Grey Heron and a Little Owl on a stone wall nearby.
Two male Bullfinches attempted to out-sing each other - the volume was deafening - not!
