As often when we offer two dates for a walk, the weather is vastly different each day.  This was definitely the case with our little forays to Cockaynes for this month’s Wild Essex events. Monday was blowy and cold, whilst on Tuesday the sun shone, and the wind had dropped.  (Sorry Keith!).

This report covers some of the highlights that we saw, heard and smelled over both days. As to be expected, the warmer conditions on Tuesday brought out more of our insect friends. In line with the calendar (how do they know?) a St Mark’s Fly was seen, slightly askew with one wing out and the other not.  Possibly it had just emerged and not fully ‘filled out’. St Mark’s Day is 25^th April! The following day we witnessed two ‘in cop’ doing what they need to do in the few days that they are alive as adults.

A little Pine Ladybird was busying itself keeping warm on a woodland leaf, and we found some Brown Tail moth caterpillars, new escapees from their conspicuous nest-webs. Their body hairs contain an unpleasant irritant and so contact should be avoided.  The only birds that can eat them are Cuckoos which have specially designed digestive processes to cope.

Famous and important residents to this site are the ‘Bunny Bees’ (Colletes cunicularis) which make holes in the sandy banks on the reserve. These are rare and it is always a pleasure to see that they are still enjoying living near us in Wivenhoe. And a host of other solitary bees were out and about in the sun including this ‘mini-miner’:

Evidence of other insect life was found, without seeing the critters themselves – leaf miner moths which lay their eggs between the surfaces of leaves and the larvae eat and grow, making patterns in leaves as they go, before emerging when fully fed, and also little cases of micro moths which were easy to spot on the rushes.

An Acorn Weevil showed its snout within the unfurling wings of an aquiline Bracken, and a tiny Dyseriocrania subpurpurella micromoth nestled into a Cow Parsley umbel. The warmer sunshine brought out butterflies on Tuesday, including Speckled Woods, Orange Tips, Large Whites and a Peacock.

We were privileged to hear lots of bird song in the couple of hours, and this varied day-to-day too.  We caught the dulcet tones of numerous Mediterranean Gulls (did I say dulcet?  – more like a posh squawk!)  – numbers in this area at the moment are at an all-time-high.  Add to that Chiffchaffs, Song Thrushes with their three-song call,  angry Cetti’s Warblers, rhythmic Reed Warblers, liquid Blackcaps, the increasingly rare Willow Warbler, Robins, Great Tits, Wrens, a bit-of-bread-and-no- cheese Yellowhammer, Linnet (below), Goldfinches and the odd snatch of Nightingale song, but sadly we did not witness its full and beautiful melodious warble.

Happily there was plenty of plant life to enjoy on both days.  This whole area was once woodland, and fortunately after the gravel extraction programme in the 80s, it was not merely filled in, capped with clay and turned over to agriculture, but was allowed to remain and rewild, giving us the reserve we know and love today. Working parties do great stuff in keeping some of the scrub under control to allow the important (and unusual in Essex) stands of Heather to thrive. These would soon be crowded out if Silver Birch and other trees were allowed to take hold.  Other interesting flora included Gorse at its peak, Town Hall Clock,  Opposite Leaved Golden Saxifrage, Thyme-leaved Speedwell, Wavy Bittercress, Greater Stitchwort, Ground Ivy and Heath Woodrush…

…and of course Bluebells, albeit a little worryingly with quite a few hybrids with Spanish Bluebell, paler, less delicate and of lower value to native pollinators.

Fungi are always fascinating, and we were delighted to find examples of King Alfred’s Cakes and a Mazegill bracket fungus.

As always we enjoyed the company of our groups – always willing to listen to Chris’ stories and ask questions and generally join in.  Thank you all!  Look forward to another walk with you before too long. Some of you asked about our fantastic close-up binoculars: they are Pentax Papilio II 8.5 x 21. We would recommend them thoroughly, and it is just a pity we are not on commission, given the number of pairs that have been bought by our ‘bug and botters’ over the past four years!

Thank you all for coming along to our walk today.  The weather was absolutely perfect – bright sun, blue sky with a gentle breeze to keep us all cool.

Gorse, that most important of plants for early pollinators, was out in profusion, and we make no apologies for starting this little blog with blue (sky) and yellow (gorse)– nature’s reflection of the Ukraine flag – a tiny, though heartfelt, show of solidarity with those suffering untold pain and misery in ‘civilized’ Europe.

This month’s event was the first time we have taken our group on this particular route, and was more of a lengthy walk than we sometimes do. Starting at the old, ruined church of St Peter we wended our way through lanes, down steps and across stepping stones until we reached the trail from Wivenhoe.  This path was once the railway line (Crab and Winkle line) which ran to Brightlingsea pre-Beeching. It is now a popular walkway, with good visual and actual access to the estuary.

The church is an interesting structure; destroyed by fire in 1971, it has acquired a beauty which only old ruins can and the churchyard itself has (at least in other years and we are hopeful for this) been managed for wildlife with areas unmown and allowed to do their own thing, although at the moment with little else showing other than (planted) Wild Daffodils. Among the grassland there are of course lots of those fascinating structures, lichens, on gravestones (see Chris’ gallery of ‘Lichenscapes’ Lichenscapes | Chris Gibson Wildlife).

So what did we see?  We had billed this event as seeing ‘first signs of Spring’ and we were certainly rewarded with lots of early Spring flowers, each an important source of energy for early emerging insects. Lesser Celandines, Greater Stitchworts, Red Dead-nettles and Common Stork’s-bills, not to mention a few (surprisingly early) Bluebells, were decorating the hedgebanks and field margins.

Blackthorn and Cherry-plum were in flower (the latter by now almost over), many of these shrubs buzzing with flies and bees making good use of their stores of food, and those biological pest-controllers par excellence, the ladybirds, were spotted here and there.  Who needs nasty poison sprays to keep aphids at bay when these beautiful little jewels will do the job for you?

Although not a Spring species, King Alfred’s Cakes, a hard, globular fungus was found on a dead Ash tree overhanging the path.

Those flying wonders-of-nature, butterflies, were out and about. How on earth caterpillars get transformed into these works of flying art is a mystery to science. We saw Peacocks, Commas and Small Tortoiseshells, but no sign of any Brimstones, although they are on the wing at the moment. And always a delight (to us if not to the bees their larvae parasitize), Bee-flies were just starting to emerge…

Birdsong filled the air; we heard numerous Skylarks, Blue and Great Tits, Robins, Chiffchaffs, Blackcaps and many others whilst strolling down to the estuary. The shore birds are beginning to leave our coastline now, the few still remaining included Black-tailed Godwits, Curlews, Shelducks, Teals and Brent Geese we enjoyed watching going about their daily lives of probing mud for scrummy little worms or nibbling on vegetation, all the while keeping their collective eyes open for real or perceived threats.  Lots were disturbed by a Little Egret which landed among them (perhaps looking too much like a Marsh Harrier),although in reality the female Sparrowhawk which flew over at the same time was more of the threat at least to the smaller birds.

The last leg of the ramble was up Ford Lane, ascending from sea-level to the peak of the Essex Alps, where Cow Parsley in very early flower gave a final taste of spring, a last boost to carry us through the cooler conditions forecast for the week to come.

Two years ago, in a very different world, we ran our last midwinter tree walks around the KGV. The blog linked here focussed on the buds and twigs, and gives a good idea of the features to look for on a selection of the species to be found. Of course, the identification of trees in winter also uses a further series of characteristics, from fallen leaves, shrivelled fruits and the nature of the bark, elements we brought into our #WildEssex walks this month. Here is a selection (photographed during our recce in much more pleasant weather than the fog of the Saturday walk!).

ASH – in addition to its unmistakeable black buds, mostly in opposite pairs, with flattened twig tips, Ash also has smooth, pale bark, often covered in lichens, and usually has some of the bunches of keys from last summer perched in its boughs.

OAK – the plump, chestnut-coloured buds are clustered at the tips of the twigs that arise from the branches that come from the trunk, covered in deeply ridged bark, the fissures more or less continuous, running down the trunk. Sometimes, in older specimens, the trunk is divided, by coppicing or pollarding, especially on old ownership boundaries where distinctive trees were used to define those boundaries legally, by way of a ‘perambulation’.

BEECH (upper two) and HORNBEAM (lower two) – The elongate, pointed shape of the buds of these two species is similar, but those of Beech are set at an angle to the twig, while those of Hornbeam are curved into the twig.  Beech often has dead leaves still attached in midwinter, and smooth, silvery bark, with raised lines, rounded in profile, running down it. Hornbeam bark is similarly smooth, but the trunk is usually fluted, like a rippling muscle.

And then to three fast-growing, often small species, good at colonising suitable habitats:

WILD CHERRY has clusters of buds borne on short, woody pedestals, and peeling, copper-coloured bark formed into distinct hoops around the trunk…

… while SILVER BIRCH has lovely white bark, delicately drooping branch tips, and often has remnants of last year’s seeding catkins at the same time as the coming summer’s catkins are starting to emerge…

… and ELDER has deeply ridged grey bark, often covered with mosses. It is also the first of our trees to burst into leaf, a true harbinger of Spring.

ELM is often distinguished as much by its dead stems, the victims of Dutch Elm Disease, as by its living features. But on a living trunk, the herringbone branching pattern of the twigs is usually apparent, as often are the main branches clothed in corky wings of bark.

Another tree bedevilled by disease is HORSE CHESTNUT, especially worrying in view of its rarity in its native Caucasus. The big, swollen buds with sticky scales are well known, but the horseshoe-shaped leaf-scars and smooth bark breaking into a patchwork of plates are equally distinctive.

Similar in name, but very different (and completely unrelated), the SWEET CHESTNUT is often noticeable by its halo of dead leaves lying on the ground, as they take several months to decay away. Its plump buds sit on ‘shelves’ on the ridged twigs, and the bark of a small tree is smooth and silvery, in marked contrast to an older tree  where the bark is strongly fissured, twisting around the trunk.

Two of our most distinctive winter trees are WHITE POPLAR, with its graceful, upswept branches, whitish twigs and buds, and hoops of large, diamond-shaped lenticels on its bark….

… and the smooth, grey bark, large, turgid buds, almost fit to burst, and beautiful bud-scales,  edged in maroon and fringed in white, of SYCAMORE.

Finally, mention must be made of the evergreens, historic adornments to the grounds of the former Wivenhoe Hall. The red-boughed SCOTS’ PINE (top) is one of only three native conifers in Britain, CEDAR-OF-LEBANON (middle) is another species threatened in its native Middle Eastern home, and HOLM OAK (bottom), native to the Mediterranean basin. But the presence of leaves or needles doesn’t necessarily make identification easier: it is always worth getting to know their distinctive fruits, tree shapes and bark. No rest for the botanist, even in midwinter!
