Jonathan Shanklin, who has been the botanical recorder locally since 2004, says, “I can report 2326 records of Vascular Plants, Liverworts and Ladybirds logged on my database during 2019 for the NatHistCam area. (This is roughly the median number, ranging from 7022 in 2005 to 1157 in 2004.) Overall there were reports of 746 different species/subspecies/variants.” The most exciting were Potentilla argentea (Hoary Cinquefoil) that Jonathan found at the Observatories and Cuscuta epithymum (Dodder) found by Alan Leslie at Hobson’s Park.
Dodder is a very strange plant, consisting of multiple stems, almost leafless and without roots. It is parasitic on other plants, over which it forms a mat. C. Epithymum has no chlorophyll and is pinkish in colour. Related to the Convolvulus family, it is parasitic mainly on legumes (gorse, clover) and also on heather. Other names include Hellweed and Strangle-tare! It likes rocky, stony and grassy habitats, favouring limestone. There have been no previous NBN records for Cambridge.
December so far has not been too cold and mammals are still being reported. Fiona spotted a Hare on Grantchester Meadows on Dec 1st. Fox sightings seem to have increased in the Gilbert Road area: two sightings in Bill’s garden, both close to the house. One was a rather lean looking dog fox, which chased two Grey Squirrels across the lawn but when they sought refuge up a larch tree, he then attempted to eat the fat ball on the bird table! Even though it was not in our study area, I can’t resist adding in the Mermaid seen on the Ouse by Mike Foley. Not long before the sea reaches us here?
Jo was excited to see an Egret at Sainsburys. (She doesn’t say what it was shopping for, however.) Holly has heard Song Thrush and Robin both singing, with occasional drumming from Great Spotted Woodpecker. She also reports a flotilla of Tufted Duck on the Cherry Hinton chalk pits. Sandie snapped a Heron on the bank in Newnham, so motionless she mistook it for a tree stump at first. Blackcaps were reported from Chesterton (Pat) and Petersfield (Val). Pam’s sharp-eyed granddaughter spotted Pied Wagtails in Chedworth St, a Grey Wagtail near the Mill Pool and a Grey Heron on Coe Fen. On Boxing Day, Pam took her four grandchildren at dusk with torches through Paradise, good floods to paddle in, blackbirds chinking, a rook flyover overhead.
Mentioning Paradise, the Pallas’s Warbler sighted in November was still there on December 2nd, but not seen since. The congregation of Twitchers also flushed a Woodcock there, which apparently was poor compensation for not seeing the warbler. At St. Johns college, Nuthatches were seen again and also a Little Egret near the Bin Brook (David).
On 4th December, U3A naturalists had an excursion to the Botanic Garden, mainly to look at Bryophytes. We were delighted to find the “Lower Plant” glasshouse behind the main ones, as it has been greatly improved. There are many more “Lower Plants” than I had dreamed of. As a bonus Paul stumbled across a couple of (rather battered) Earthstars on the way out. At Byron’s Pool, another group came on some Stump Puffball at the foot of an Oak tree and in Paradise, Oyster Mushrooms were growing on dead Willow (thanks Bernie).
Paul sent a few more bug records: “Synophropsis lauri” is a Leaf Hopper and another species that has recently established itself on these shores (first UK record 2007). Females are believed to over-winter as adults. Sitona lineatus (Pea Leaf Weevil) was found hibernating in the seed pod of Love-in-the-Mist. Finally a very unseasonable moth record from 19th December: a Silver-Y Moth. These are common migrants, normally seen in large numbers from late summer into autumn.
Lesley reports a Bee in Highsett on 27th, also an Earthworm on the pavement and was delighted to assist it by putting it on grass. Winter proper has yet to come, evidently.
Finally, I copy you Alec’s commentary on his garden birdbath verbatim: ”I have the usual population of blackbirds and sparrows flitting about amongst the bare branches of my Forsythia. Yesterday, 31st December 2019, a sparrow was happily enjoying a lively bath in my birdbath (a pottery basin) on the ground when a blackbird suddenly jumped in and trumpeted, “You! Out!”. The sparrow reluctantly stepped out, but hopped around the bath watching the splashing blackbird indignantly. Then it hopped right back into the bath and exclaimed indignantly, “No! You, out!” and flapped around in the water as belligerently as it could. “Blimey!” quoth the blackbird. “All right, all right!” thinking, these little squirts can certainly lose their tempers, can’t they? And it got out and decided to wait its turn. Which shows how important a cold bath is to birds in midwinter… doesn’t it?”
Happy New Year and thanks to all contributors
