November has been mild, although generally rather wet and dreary. Bats (probably Pipistrelles) were flying on Nov 2nd over the New Bit of Coe Fen and still on the wing in Paradise on Nov 25th (Paul). A Red Admiral Butterfly was seen on Viburnum in the sun on 10th (Olwen) and an Ivy Bee in early November (Pam).

Birds It has been another exciting month for birds (see Bob’s blog for fuller details). A Peregrine was seen flying over Arbury November 3rd (Ben) and on Nov 14th in Gilbert Rd, May was alerted by the clatter of Magpies and then startled to see a Peregrine kill a woodpigeon in the garden. Ben spotted a Woodcock flying over Arbury. Guy had a lovely view of swimming Water Rail by St Bedes along Cherry Hinton Brook on 13th and on 18th, Alan saw another at Logan’s Meadow Nature Reserve in Chesterton. (I had always imagined they were summer visitors, but I gather that while northern and eastern populations are migratory, they are a permanent residents in the warmer parts of their breeding range and the UK may also have immigrants from Europe.)
Another Nuthatch sighting from the Backs, this time on a lime tree at Clare College, in the Fellows Garden – down the “Tunnel of Gloom” (Kate). Guy spotted a pair of Bullfinches by Byron’s Pool car park, along with a Kingfisher and Brown Rat doing its best impression of a water vole. (It must be hard being the City Ecologist!) Vicky reports a very fine Jay just outside her window in Highsett and Pam has a Great Spotted Woodpecker visiting feeders regularly with Gold Finches and Long Tailed Tits. Val’s small central back garden saw the first Starlings in ages, a male Blackcap and a glimpse of a Woodpecker. U3A naturalists spotted a Treecreeper in Cherry Hinton Hall, on a visit to follow the excellent tree trail there.
Holly’s regular update on Cherry Hinton Brook : Usual passerines along the brook (Tits, Blackbirds, Robins, Wren,) and waterbirds (Moorhen and Mallard), with Kingfisher and Little Egret, but no Winter Thrushes, Brambling or Siskin yet. However, Penny reports a probable Redwing stripping the neighbour’s holly tree of its berries. In Tenison Road, Martin has male and female Blackcaps feeding on ripe grapes. In Fen Ditton, Trevor had a Jay visiting the nut feeder (but soon altered the mesh to exclude him). He identified Coal Tits visiting for the first time.
The star attraction this month was the Pallas’s Leaf Warbler, which turned up on Nov 21st in Paradise, in company of tits, Goldcrests and a Chiffchaff. These tiny, strongly migratory birds are about the size of a goldcrest and weigh only slightly more than a table tennis ball. Although they are an East Asian species (N. China, migrating to S. China and Indonesia in the winter) they are nevertheless found regularly in Europe and UK and this may be an alternative migration route. This rare sighting then resulted in a secondary sighting: an invasion of Twitchers with Long Lenses and Large Binoculars, generally arrayed along the river path, sighing heavily.
Fungi The CNHS fungus foray in the Botanic Garden turned up a good number of species. The highlight for me was the Bird’s Nest Fungus which has arrived with the wood chippings under the new raised ramp. Louise sent these pix, from the West Cambridge Site and as each contain a drop of water, you can see the reflection of sky and trees in the cup.
Orange Peel Fungus was found in the car park area at Cherry Hinton Hall. Paul spotted Arrenhia rickenii growing in moss on the top of a concrete gate post. They are so tiny, they are probably mostly overlooked! Another tiny, on a twig in Beechwoods reserve, was one of the Crepidotus family (Paul), while bigger and bolder were the Wrinkled Peach fungus, Rhodotus palmatus and Oyster mushrooms Pleurotus ostreatus, both found in Newnham on decaying wood.
Mammals Foxes become ever bolder – one was spotted Kingston Street at about 10pm (Jonathan) and another in broad daylight in the grounds of Churchill College (John). A pair of Muntjac appear to be living in Histon Road Cemetery: this photo was taken from an upstairs window on Bermuda Row. Lesley comments on increasing numbers of Black Squirrels there and also one was reported from Fen Ditton (Trevor).
Invertebrates Paul reports a couple of November Moths: Blair’s Shoulder Knot (on the wing from Oct to Nov) and Mottled Umber (males on the wing from Oct to Dec, females are flightless). This Harvestman, Dicranopalpus ramosis was basking on a wall at Jesus (Rhona).

Plants In the now wooded chalk pit at Limekiln Close, Sharon found a small patch of the beautiful Common Tamarisk-moss Thuidium tamariscinum. This is indeed a common woodland moss in the west of Britain, but has become increasingly rare in Cambridgeshire’s ancient woods. Maybe is now starting to spread again, as it was found in 2017 in Barnwell East LNR and near Fen Ditton earlier this year.
For a couple of years, Charles had admired the annual Claytonia perfoliata, Springbeauty, growing between house wall and pavement in Milford Street, only to find that, although very little grows in these rather barren streets, anything green had been sprayed with weedkiller. Happily, a few fresh seedlings of Claytonia have now reappeared.
