When Leo was ranger there, skylarks were still breeding and water voles were on the river. There was also a report of an otter being seen. Spraints were found where the Cole joins the Blythe. There was also several sightings of an otter along the river at Trittiford and at Scribbers Lane, the most recent being in 2012.
I've always reckoned the description of the character Gollum in LOTR was based on an otter.
Glad you've confirmed the little egret. A couple of people (dog walkers) I know reckon they've seen one recently along the canal, where the Chinn Brook goes into the Cocks Moor Woods Golf Course. The Dingles is another place where it seems to turn up.
The Environment Agency carried a fish survey and confirmed brown trout are still in the Cole, with good numbers under the road bridge at Sarehole Mill, at Four Arches by the weir and also by the Aqueducts.
Ring necked parakeets bred at Green Road Ford and it was a good place to see lesser spotted woodpecker but sadly there have been no records since 2012. Up to four pairs were known to be present in the general Hall Green/Yardley Wood area but a succession of bitter winters, cold springs and wet summers have put paid to them.
A pair of willow tits were still breeding up to 2007 and spotted flycatchers were still around until the mid 1980's. Reed buntings are another bird recently lost. Mistle and song thrushes are rarities. Only know of one place where kestrels still breed. I even think sparrowhawk numbers may have peaked. However, house sparrows are common along the Cole Valley.
Still occasionally see woodcock and there is one section where reed warbler and water rail breed; at another, snipe overwinter.
Black redstarts were breeding on the Cole. One site has since been demolished. Also gone are breeding linnets and goldfinches.
I moved into the area in the late 1950's and can recall much of it still being fairly rural and affluent, with gardens the size of tennis courts, many of which were mini orchards. Older people told me they can remember barn owls and red squirrels around that time, although obviously by then the respective populations were in irreversible decline. There was certainly grass snakes. Newts and toads are now scarce. Muntjac deer are reported everywhere and two roe deer were photographed on one of the sites managed by the ranger service.
According to the WMBC annual reports for the late 1940's and early 1950's, little owls were still in the Hall Green district.
Go back a hundred or so years and there would have been nightingales, cuckoos, red backed shrikes, redstarts, tree sparrows, plus a host of other species.
Quite sad what has been lost.
Common buzzards are now breeding locally (even had one in the back garden) and ravens are seen fairly regularly. Other flyovers include peregrine, red kite, hobby, osprey and common tern.
Just imagine the list I could have had if I'd spent less time watching Blues and other dubious pursuits.
