Meadows and the Agriculture Bill

Ancient meadows have quietly disappeared from under our feet. Without the roar of chainsaws or the sound of mighty oaks crashing to the ground, sites with undisturbed floral histories going back generations can be lost in a single afternoon. Since the 1930s, over 97% of our meadows – a staggering 7.5 million acres – have been ploughed, ‘improved’ or built on. This is a key driver in the higher-profile declines of pollinators and birds – and a loss to us all.

Cranes by Sue and Andrew Hetherington, Gallows Bridge 16 May 2018

Cranes in Buckinghamshire 2018

Two cranes arrived at Gallows Bridge BBOWT reserve on Wednesday 16 May 2018.  They remain there to date (21 May 2018) so it is a possibility they will remain.  They are unringed which gives some clues as to where they came from – or rather where they did not come from.  Educated guesses say they may have come from Otmoor.  Some display behaviour has been observed.

Record your Red Admiral sightings

Red Admiral by Harry Appleyard, Tattenhoe Park 22nd September 2016

Red Admiral by Harry Appleyard, Tattenhoe Park 22nd September 2016

Have you seen a Red Admiral? Please record it!

The Red Admiral (Vanessa atalanta) is a migratory butterfly colonising Central and Northern Europe every year from the South. In autumn, the offspring of these spring arrivals migrate southwards.

We investigate the migration of the Red Admiral by the help of citizen science. Thanks to the more than 40 citizen science portals across Europe that share their data with us, we are now able to study Red Admiral occurrence in an unprecedented spatio-temporal resolution.

Starlings v Swifts – updated 21 May 2018

My daughter and her partner live in Cumbria and have starlings and swifts nesting in the eves of their house. Last year the starlings nested first and then the swifts moved in once the starlings had fledged. This year as normal the starlings are busy bringing up their babies in the usual place.

However last Saturday 12th May Susies partner heard a cacophony outside the house and saw a starling and swift tumbling together down onto the lawn followed by a tussle where the starling clearly had the upper hand and the swift’s life was at risk. He rescued the swift and after a rest launched it from an upstairs window. However after a while he saw the swift attempt to enter the nesting cavity and again the tussle ensued followed by another rescue and relaunch. Now a stalemate is in place where the swifts regularly fly by but the starlings are on high alert and drive them off.

This year they have erected two more swift boxes hoping to establish a small colony but it seems like this won’t be given a chance to happen until the starling family have fledged and moved out. But it leaves you with questions – does this competition happen regularly and do the swifts loose out. Or was it just because the weather was unseasonably hot that the swifts decided to try and get a move on early an start nesting?

Article by Julie Lane

And now an interesting response from Sue Hetherington:

Starling by Harry Appleyard, 20 April 2016

Starling by Harry Appleyard, 20 April 2016

I was interested to read Julie’s article about the nesting territories under dispute by starlings and swifts. I can’t offer any advice about the eaves of the house. However, Andrew and I have had similar worries about the possibilities of uninvited guests grabbing boxes intended for swifts.

Before our box was used, we found evidence that it had been used for roosting by some bird over the winter and realised a problem could arise. What we then did as autumn turned to winter, we cleaned the box out (which we no longer do, it’s not necessary) and we blocked the entry hole with a bathroom (or car washing) sponge.

We reckoned our swifts came back like clockwork on 3rd – 5th May so about half way through April, we removed the sponge. We always meant to attach a bit of cord to the sponge so it could be pulled out with having to start going up ladders, but of course we always forgot. It always appeared to us that the starlings wanted an earlier slot than the swifts so our sponge method always seemed to work.

I have heard of swifts having savage territorial disputes amongst themselves but hadn’t realised that a swift/startling fight could be so vicious. This competition for nesting sites sounds like yet another problem swifts are struggling against.

Rutland Osprey Project has reported that Maya (a female osprey) and her mate (known as 33 after his ring number), have successfully incubated a trio of eggs that began hatching during the early May Bank Holiday weekend.

This is the earliest recorded date of osprey eggs hatching at Rutland Water, and follows the earliest return date and egg laying of UK ospreys when Maya was spotted at her nest on 12 March, five days before the previous earliest return date on record.

Save Salcey Forest Treetop Walk

Salcey Forest Treetop Walk is being closed, apparently due to neglect it has now become too dangerous to use.

The treetop walk is a large part of our community and hundreds of visitors, families and walkers will now be missing the opportunity to visit the forest for this fantastic addition to Northamptonshires countryside. We would like to urge the Forestry Commission to undertake the relevant repairs required in order to keep this well-loved attraction open.

Upper Thames Wader Project

The Upper Thames area is important for its wet grassland and flower-rich meadows, and has historically supported large populations of breeding waders such as curlews, lapwings, snipe and redshank.
However, surveys in 1994, 1997 and 2005 showed that all four species had suffered significant declines. The project sets out to reverse this decline.
The project area supports large numbers of lowland curlew and lapwing, as well as wildlife such as brown hairstreak and turtle dove. In the face of pressures on habitat, flood risk and climate change, farmers, conservationists and local communities are working together to give nature a home across this landscape.

Wildflower-rich meadows

Wildflower-rich meadows are very rare and important habitats. Some of these grasslands support an amazing number of wildflower species as well as providing habitats for many species of birds, invertebrates, amphibians and mammals. In particular they provide very important supplies of pollen and nectar for bumblebees and other insect pollinators.

White-legged Damselfly Investigation

The White-legged Damselfly (Platycnemis pennipes) is a delicate little insect that can be found fluttering along lushly vegetated margins of rivers, streams, pools and lakes in southern England and Wales. At first glance they can be mistaken for other, more common, species of blue Damselflies, such as Azure Damselflies; as a result, it is likely that White-legged Damselfly are under-recorded. However, on closer inspection the species can be easily be identified by a number of features, the most prominent being its pale legs, which are broad and feathery in males.

Properties of flexible resilin joints on damselfly wings

Emperor Dragonfly, Stonepit Field, 15Jul14, Peter Hassett

Emperor Dragonfly, Stonepit Field, 15Jul14, Peter Hassett

Resilin functions as an elastic spring that demonstrates extraordinary extensibility and elasticity. Here we use combined techniques, laser scanning confocal microscopy (LSCM) and scanning electron microscopy (SEM) to illuminate the structure and study the function of wing flexibility in damselflies, focusing on the genus Rhinocypha. Morphological studies using LSCM and SEM revealed that resilin patches and cuticular spikes were widespread along the longitudinal veins on both dorsal and ventral wing surfaces. Nanoindentation was performed by using atomic force microscopy (AFM), where the wing samples were divided into three sections (membrane of the wing, mobile and immobile joints). The resulting topographic images revealed the presence of various sizes of nanostructures for all sample sections. The elasticity range values were: membrane (0.04 to 0.16 GPa), mobile joint (1.1 to 2.0 GPa) and immobile joint (1.8 to 6.0 GPa). The elastomeric and glycine-rich biopolymer, resilin was shown to be an important protein responsible for the elasticity and wing flexibility.

Hubble captures  “Einstein ring” created by distant galaxies

This image might look like someone left a coffee mug on a photograph of some Christmas lights, but it actually illustrates a fundamental part of our understanding of physics.What you’re looking at is a picture filled with distant galaxies, and in the middle of the image is a particularly dense cluster of galaxies. So dense, in fact, the cluster is distorting spacetime and creating what’s known as an Einstein ring.

Hollington Wood Bluebell Open Day 7 May 2018

By a quirk of the calendar, this year’s May Day bank holiday falls as late as it could – on the 7th. Thanks in part to The Beast From The East, everything is a week or two late this year so the bluebells will still be at their peak by next Monday. Even the forecast is now looking great, after the final sting in winter’s tail this weekend!

Arrangements for the Open Day as normal –

  • free access to all of the wood 10am-5pm
  • parking on site £10 and must be pre-booked through me (not on the day please!)
  • lots of refreshments and home-made goodies
  • guided walks (11am & 2pm), children’s activities and target practice
  • be ready for lots of mud (although I hope everything will have dried out nicely by then!).

Crows have learnt how to eat cane toads

MEMBERS OF THE crow family, the corvids, show a capacity to learn and solve problems that may be unrivalled in the bird world. It seems their greatest skill is an uncanny ability to turn new and tricky situations to their advantage.

Take the scourge of the introduced cane toad (Rhinella marina) for example. As this highly poisonous amphibian disperses across northern Australia, the numbers of predators attempting to eat them are crashing. The most notable victims are quolls, goannas and certain snakes, which have been all but wiped out in some regions. Crows, however, have learnt how to eat toads by avoiding the most toxic parts.

The large parotid glands on the toad’s neck and shoulders are the greatest risk. When a toad is harassed, milky white poison oozes from these glands. Any contact with this ooze is a likely death sentence. In many cases they die before even swallowing the toad.

How do cuckoo bumblebees trick other species?

In a bumblebee nest, a single fertile female, the queen, dominates the infertile female workers using a chemical scent – pheromone – identifying her as the egg-laying mother of them all.

Usually, all proceeds peacefully, but in some cases an intruder queen kills the nest’s matriarch and takes over.

Peregrine Platform at Stadium MK ©Sue Hetherington 28 April 219

Peregrine Platform at Stadium MK

Location: Stadium MK
Date: during first half of MK Dons v Scunthorpe Sat 28/4/18
Message: Just a record shot but it may be of interest to anyone unaware of the existence of a pair of breeding peregrine falcons at Stadium MK.  They are using (for the first time) a platform provided for their use. As will be seen, it is high up, just before the transparent part of the roof, between aisles 10 and 11.  Shortly after the photo taken, an adult peregrine flew from the platform and perched at the opposite end of the stadium.  Andrew and I appeared to be the only people who noticed it.  Having never been to stadium MK before, I had to ask many stewards for information before I discovered the platform location.  One was particularly surprised and exclaimed “I’ve never been asked that before!!!”

Birds of a feather, fly together

It’s pleasing to have a flock of Siskins arrive in your garden, and thanks to ringing, we might know where they come from or go to, but can ringing tell us anything about the link between these individuals in the flock? A note in Bird Study by Juan Senar and Jeff and Allison Kew in 2015 revealed that the individuals in Siskin flocks have stable social bonds and move in stable social units.

Shaping positive engagements with urban birds

Some bird species provide cultural services, being aesthetically pleasing and having behaviours that people find interesting to watch. Others provide disservices (e.g. gulls, pigeons and corvids) negative for well-being. By documenting how the abundance and richness of species in these two groups correlates with human population density it was apparent that socio-economically deprived areas support low ratios of birds to people, particularly of cultural service species. These results inform management of green space, and provision of feeding and nesting sites, to promote positive interactions between birds and people within urbanised landscapes.

Ulidiidae (wing-waving flies)

Ceroxys urticae female

Ceroxys urticae female

A relatively small family (20 British species) containing some very distinctive picture-winged flies, many of which can be identified in the field with the naked eye or a hand lens. Many of those picture-winged species actively wing-wave as they walk over foliage (e.g. Herina and Seioptera) or tree trunks (Myennis).

Great Linford Manor ©Peter Hassett 7 July 2015

Dear Bucks Geology Group members, the up and coming events at Great Linford are yet another way of looking at geology but in a slightly unusual manner; and a chance to explore a stone circle  – an unusual feature of Buckinghamshire.

The BGG’s AGM this year will be held at the Art Centre Great Linford, and will be followed  by a local walk.

–       The AGM runs 1-1:30 – members and non-members alike are welcome to join us;  there is then a linked event

–       The walk runs 1:45 – 3:45pm. NB people who’d like to come on the walk but not the AGM are very welcome, the events are separate from that point of view, just sequential for those who wish to come to both.

For the main walk – If you fancy a gentle stroll with us to learn about the Jurassic Blisworth Limestone and its fossils through the building stones of Milton Keynes Arts Centre, St Andrews Church and Great Linford Stone Circle & Old Quarry; ending with a visit to MK Parks Trust’s Stone Pit field well known not only for its limestone surfaces but also wildflowers and insects.

For those who can’t open the attached flyer the key details are as follows:-.

  • AGM only – Saturday 12th May 2018 1:00 – 1:30
  • Following walk , same day running 1:45 – 3:45
  • Approximately 2kmon mostly flat terrain (no big hills!) although in places the ground can be a bit uneven.
  • Wellies and specialist footwear not needed but sturdy shoes / walking boots are advised. Obviously dress for the weather on the day.
  • Meet at the Milton Keynes Arts Centre. Parklands (off Ledgers Drive), Great Linford. Milton Keynes. MK14 5ZD
  • Members free; non-members £3
  • If you’re planning to attend either or both events please let Mike Palmer know on 01296 325223 or email mpalmer@buckscountymuseum.org

Woodland edges: why their structure is important for birds 

The patchwork of woods and fields seen across much of lowland Britain contain extensive lengths of woodland edge that could have a big impact on our woodland bird populations.

A new study between Bournemouth University, Centre for Ecology and Hydrology and the RSPB looked at how the structure of trees and shrubs in Cambridgeshire woods affect bird populations.

Trip Report – Linford Wood 15 April 2018

About a dozen MKNHS members and others assembled at Linford Wood at 2.15pm on Sunday afternoon 15th April 2018 at Breckland, by the north-west entrance to the wood. The weather was warm but cloudy and rain arrived shortly before the walk finished. There had been a rush of plants coming into flower over the preceding week of warmer weather and the first migrant birds had arrived not many days before.

In 2017, the MKNHS visit to Linford Wood had been on a Tuesday evening more than three weeks later (5th May) so this daytime visit, earlier in the season, provided a very different view of the wood and its flora. Mike LeRoy gave a brief introduction which was set out more fully in three handouts: 1) a map of the whole wood and its compartments; 2) a background note about the history, ecology and management of the wood; and 3) a note of ‘What to look and listen for’.

Five leaved Herb Paris by Peter Hassett, Linford Wood 2 May 2017

Five leaved Herb Paris by Peter Hassett, Linford Wood 2 May 2017

The group walked together on an anti-clockwise route along the western and southern sides of the wood, past compartments 13 and 7a which have been extensively coppiced and thinned during the past winter. At the south-east corner, we headed back towards the centre of the wood and diverted briefly onto the western woodchip path to find Herb Paris Paris quadrifolia before heading back to Breckland along the main horse-riding path as a shower started.

The main questions the group focused on were:
1. What plant species are flowering?
2. Where do you see Dog-violets or other Violets?
3. What bird species can you hear calling?
4. What woodpecker sounds do you hear?
5. Which Bumblebee species do you see?
6. What Bee-fly species do you see hovering?
7. Which of the ponds can you see?

Wood Anemone

Wood Anemone

Wood Anemone Anemone nemorosa had been in flower for a couple of weeks and there must have been tens of thousands to see, scattered throughout most of the wood. Although it was the most dominant plant in flower, there were also considerable numbers of Dog’s Mercury Mercurialis nemorosa still in flower alongside the paths. There were also still plenty of clumps of Primrose Primula vulgaris in flower in and among the trees and along the edges of the ditches. The delicate leaves of Pignut

Conopodium majus were seen in a few locations on ditch and path edges. Only a few Bluebell Hyacinthoides non-scripta were beginning to show. Lesser Celandine Ranunculus ficaria were still in flower, but Greater Stitchwort Stellaria holostea had yet to emerge and no flowering Yellow Archangel Lamiastrum galeobdolon were seen. The first few Herb Paris Paris quadrifolia were just emerging into leaf, but had not quite flowered. The group found a few clumps of Strawberry which turned out to be Barren Strawberry Potentilla sterilis (identified by Mary Sarre).

Violet sp. ©Peter Hassett Stanton Wood, 12 May 2010

With the undergrowth yet to burst into full growth, Dog-violets and other Violets Viola spp. were more evident and found in small numbers through much of the wood. Most of the trees were barely into leaf so there were clear views well into the wood.

Although tree species were not a main focus of what we looked for, Mary Sarre noted at the edge of the wood near Breckland some Norway Maple Acer platanoides which flower with bright yellow-green flowers before they leaf and have been widely planted in Milton Keynes. Mike LeRoy mentioned Ash Fraxinus excelsior trees close to Breckland with their brief display of purplish-brown male flowers.

Aside from the permanent ponds, there were many areas of the wood with water lying on the surface. At one pond on the western side Martin Kincaid found Pond-skaters Gerris spp.

Red-Tailed Bumblebee by Harry Appleyard, Tattenhoe 11 April 2016

Red-Tailed Bumblebee by Harry Appleyard, Tattenhoe 11 April 2016

As we walked, we noticed numerous Bumblebees hunting low down within the vegetation rather than searching for nectar. Species seen included: Red-tailed Bumblebee Bombus lapidarius and Buff-tailed Bumblebee Bombus terrestris. Another insect present in many places was the Dark-edged Bee-fly Bombylius major. Less common was the Hairy-footed Flower-bee Anthophora plumipes. In several places we found 7-spot Ladybird Coccinella septempunctata.

Male Blackcap by Harry Appleyard, Tattenhoe, 17 April 2016

Male Blackcap by Harry Appleyard, Tattenhoe, 17 April 2016

Sue & Andrew Hetherington led the recording of birds, almost entirely by calls and songs. In all they noted 17 species: Blue Tit, Great Tit, Coal Tit, Long-tailed Tit, Wren, Robin, Chaffinch, Dunnock, Goldcrest, Chiffchaff, Blackcap, Nuthatch, Blackbird, Great-spotted Woodpecker, Green Woodpecker, Jay and Magpie. Other species known to be sometimes present, but not seen or heard on this occasion, are: Marsh Tit, Bullfinch, Treecreeper, Song Thrush, Sparrowhawk, Kestrel, Buzzard, Pied Wagtail and Stock Dove.

Early-purple Orchid by Peter Hassett, Linford Wood 2 May 2017

Early-purple Orchid by Peter Hassett, Linford Wood 2 May 2017

A week after our visit the Bluebell Hyacinthoides non-scripta are out in profusion. The first Greater Stitchwort Stellaria holostea have emerged. A few stems of Yellow Archangel Lamiastrum galeobdolon have been found, but are not quite in flower. And the first of the Early-purple Orchid Orchis mascula are just emerging.

There are species of flower in Linford Wood worth looking for in mid-April and others that don’t tend to emerge until late April into May. The wood is worth visiting at both these times to see how the season is changing.

To mow or to mow less?

Red-Tailed Bumblebee by Harry Appleyard, Tattenhoe 11 April 2016

Red-Tailed Bumblebee by Harry Appleyard, Tattenhoe 11 April 2016

Green spaces embedded within the urban matrix, particularly residential yards, could mitigate negative aspects of urban development and provide pollinator habitat.

Lawns represent a dominant green space, and their management consists of frequent mowing to inhibit the growth of ostensibly “weedy” species (e.g., dandelions and clover).

Since widespread population declines of bees and other pollinators from habitat loss are a growing concern, these spontaneous flowers could provide pollen and nectar sources throughout the growing season.

We experimentally tested whether different lawn mowing frequencies (1, 2 or 3 weeks) influenced bee abundance and diversity in 16 suburban western Massachusetts yards by increasing lawn floral resources.

Lawns mowed every three weeks had as much as 2.5 times more lawn flowers than the other frequencies. Interestingly, lawns mowed every two weeks supported the highest bee abundance yet the lowest bee richness and evenness. We suggest these patterns were driven by a combination of more abundant floral resources (compared with 1-week yards), easier access to lawn flowers due to shorter grass and a more drastic impact on grass biomass and floral resources (compared with 3-week yards), and the dominance of a few generalist bees overwhelming our samples, thus driving richness and evenness.

Our results highlight a “lazy lawnmower” approach to providing bee habitat. Mowing less frequently is practical, economical, and a timesaving alternative to lawn replacement or even planting pollinator gardens. Given the pervasiveness of lawns coupled with habitat loss, our findings provide immediate solutions for individual households to contribute to urban conservation.

The sun just developed three new holes

The sun is up to old tricks again, having recently developed three new coronal holes. And it’s us Earthlings that are bearing the brunt, occupying a planet hit by geomagnetic storms.While this might sound like I’m hailing the next rapture, I’m not. Solar holes aren’t uncommon, particularly given that we’re in the solar minimum – a stage in the sun’s 11-year activity cycle in which coronal holes are pretty regular.

Gulf Stream current at its weakest in 1,600 years

The warm Atlantic current linked to severe and abrupt changes in the climate in the past is now at its weakest in at least 1,600 years, new research shows. The findings, based on multiple lines of scientific evidence, throw into question previous predictions that a catastrophic collapse of the Gulf Stream would take centuries to occur.

White Stork reintroduction project

There is significant evidence to show that White Storks were once a breeding bird of Britain, with an archaeological record stretching back 360,000 years.

White Storks are particularly associated with the county of Sussex. The Saxon name for the village of Storrington, near Worthing, was originally “Estorchestone”, meaning “the village of the storks”. A pair of white storks still features on the village emblem. Other place names in the area, such as Storwood and Storgelond, evoke the stork’s historical presence here.

Together with a number of private landowners in West Sussex, East Sussex and Surrey, and in partnership with the Roy Denis Wildlife Foundation, Warsaw Zoo and Cotswold Wildlife Park, Knepp Estate is helping to establish a breeding population of free-living White Storks in Britain once again.
