Moth night (28/8/2015) results summary.

We now have the results from Friday nights survey. 4 moth attracting lamps (125W mercury vapour bulbs) were in use around the weighbridge yard & track entrance with moth experts identifying the moths caught. The moths were collected in small plastic pots & released later after the final count. A total of 54 species were identified, with names such as Latticed Heath, Canary-shouldered Thorn & Angle Shades. This brings our species count this year on the site to 92 from the three survey nights. These results will now be forwarded for inclusion in the national database which monitors changes in populations. The full Friday list is shown below:-

Open Day, Saturday 28th June 2015

We had a lovely sunny start to our open day over at the Cockaynes Wood reserve last weekend.  The rain did arrive later on in the morning but not before plenty of visitors arrived to see the site and try the activities available.

Refreshments were set up in the old Nissan hut with the assistance of the Tendring group of Essex Wildlife Trust. The Cockaynes Wood Trust marquee provided information about the site and general wildlife information and various activities for children including directions for the family nature trail and colouring pages.

In the main yard area, there was a craft activity provided by Essex Wildlife Trust and also demonstrating the pole lathe and green woodworking techniques we had both the Colchester Countryside Volunteer Rangers and Mark, one of our regular work party volunteers. The CCRV are based at Highwoods Country Park in Colchester and use locally sourced materials to make a variety of wooden tools, utensils and bird and insect boxes among other items.

Guided walks around the site were led by Cockaynes Wood Trust with the assistance of members from the Colchester Natural History Group who were on hand to lend assistance with identifying many of the plants and insects seen on the day. Some of the highlights seen included the very well camoflaged Brimstone butterfly caterpillars on the Alder Buckthorn trees, Oyster Catchers on the scrape and Reed Warblers flying around the ponds.

Our new pond dipping platform on the small pond proved to be a huge success with children and adults alike. The pond proved to be teaming with wildlife and it was great to be able to help everyone identify the creatures they found. These included many juvenile newts (efts), several different species of Dragonfly and Damselfly larvae, snails, freshwater leech, shrimps and a water stick insect.

All in all, a lovely day was had by all despite the rain which did keep visitors away in the afternoon. We are looking forward to building on the successes of this event for next year as the site continues to grow and improve.

Lots more pictures of the day can be seen on the Event Photos page here.

A walk on site today to put up posters for the Open Day (28th June) & meet people enjoying the Reserve. Unfortunately one of the posters was torn in half by the time we got back to our car, but it was mended for others to read. At the Scrape we spotted two of the Lapwing chicks (one flew across the water as we walked past) with one of the adults, the other adult was on the far side of the Scrape & too far to see any other chicks. There was also a Moorhen with five chicks on the water & a Coot family also. On the Small Pond we saw a Coot with four chicks. Walking through the Meadow area we found more of the Yellow Rattle flowers, a Meadow Brown Butterfly & a Small Skipper butterfly. In the Yard area we found Cinnabar Moth Caterpillars on the Ragwort plants with plenty of the moths flying. We also found some Brimstone Moth Caterpillars on the Alder Buckthorn trees in Cockaynes Wood.

Warden’s Notes 10/6/15

A short walk on site this morning found several Common Blue and some Small Heath butterflies on the meadow area. Also there are a small number of Yellow Rattle flowers, a Dog Rose in flower and the orange Fox And Cubs at the top of the meadow near the old tree stumps. The Gorse on the Heath is showing bright yellow flowers and if you look a bit closer to the ground, some of the older heather is just starting to show signs of flowers. Not so encouraging is the spread of bracken on the Heath which will need some method of control soon by our Work Party Team. Better news is that the Common Cow Wheat (one of the rare species which is found on our site) is spreading / flowering along the path in Cockaynes Wood & along the heath into the bracken. Birds seen today included the Kestrel hovering by the Large Silt Pond & a Hobby Hawk over the Scrape. The Hobby was diving & swooping over the water chasing dragonflies, but was too quick & not close enough for any photo shot. It did, however, get too close to the Lapwing chicks & was chased by the adult lapwing. On the small sand cliff by the metal gates I found a Tawny Mining Bee near it’s nest hole & lots of Digger Wasps visiting their nest pipes nearby (the nest pipes are sometimes sticking out of the sand by up to 20mm of more & 8mm diameter, we will upload some pictures onto the website soon).

Moth Night Friday 22nd May 2015

Cockchaffer Beetle Moth Cockaynes Wood

Cockchaffer Beetle

We had great weather for our first official moth night of the season. We had three moth traps set up around the yard area and had a very successful night with around fifty different moth species identified. As an added bonus, we had an invasion of newly hatched Cockchafer Beetles attracted to the lamps.

With the help of Essex Bat Group we were able to use a bat sound recording device and confirmed the presence on site that evening of four species of bats. Common Pipistrelle, Soprano Pipistrelle, Noctule and Brown Long Eared.

On site this week : birds, butterflies and snakes

As the weather continues to improve, spring is well and truly on its way down at Cockaynes and Villa Woods. If you walk along the public footpath through Villa Wood this week you’ll find Wood Anemone, Primrose and Celandine already in flower. The primroses are nearly finished flowering but the bluebells are just beginning to come into bloom. In about 2 or 3 weeks, we are expecting to have a beautiful display of bluebells in both woods.

In bird news, Dave and Mo report from their walk yesterday (11th April) hearing the first Nightingale of the year in the south end of Villa Wood. Interestingly they noted that this was the same date as they heard the first Nightingale on site last year! A Cetti’s Warbler was heard calling from the reeds beside the bridge between the ponds and for the first time this year, a Willow Warbler was heard in the Birch and Willow scrub of the old silt lagoons. Buzzard and a Red Kite, both along the Villa Wood end of the scrape.

On the main scrape this week we have seen our regular Coots, Moorhen, Tufted Ducks, a pair of Mallards, a pair of Canada Geese and of course our resident Mute Swans who are building their nest in the centre of the scrape again this year.

This week we have had two reports of grass snakes on site. It is still fairly early but our resident reptiles are beginning to emerge from hibernation. The first sighting was of a juvenile grass snake among the leaves in Villa Wood sent into us by  local walker Helen and the second by our warden Roger of an adult (approx 2 ft 6″ in length) sunning itself on the stones behind the silt ponds before it took off for a swim across the pond.

In butterfly news, there was a Brimstone in the yard, Peacock and Comma butterflies in the north end of Villa Wood and a Green Veined White butterfly at Sunnymead Cottage.

Our colony of ground nesting or mining bees, Colettes Cunicularius, found in the dunes of the yard is also showing frenetic activity at the moment.
