Feathered Friends

Feathered Visitors to Wicor Primary School, Portchester

Even though it is winter, and very cold over the last few weeks, we have been getting lots of bird visitors to our grounds.  In particular, we have a resident green woodpecker which we regularly see in our woodland area.  We decided to investigate green woodpeckers, Picus viridis, a little more and found out that they stay in the UK all year round.  We were really surprised to find out that they only reached the Isle of Wight in 1910 as that’s only a small jump across the water from us.  However, apparently that was the bit that green woodpeckers weren’t that keen on.  We were also really surprised to find out that they have weak bills as we often hear our woodpecker tapping away in the trees but they prefer soft dead wood when excavating for a nest.  We think our green woodpecker is female as we can’t see any red under her bill.   The green woodpecker likes a deciduous habitat and short grass, both of which we have lots of.

It really is a beautiful bird giving flashes of colour amongst our dark winter trees at the moment.  It has bright green on its upperparts, with a pale bellow underneath, a bright yellow rump and red on the top of its head.   Apparently, it has a nickname of ‘yaffle’ because that’s what its call sounds like – we hadn’t noticed this and will be listening out carefully over the next few weeks to see if we can identify it by its call before we see it.

In the summer, green woodpeckers like to eat ants (adult, larvae and eggs).  In the winter, when there aren’t so many ants around they will eat other invertebrates, pine seeds and fruit.  Green woodpeckers usually spend most of their time feeding on the ground, although at school we mostly see them in the trees – maybe there are too many children on the ground!   We have left lots of rough soft patches of grass around our woodland area and in the orchard for the green woodpecker to encourage them to feed and breed at school.  The Picus viridis has a long sticky tongue which can fish for ants deep in the nests for as long as an hour and will keep going back to the same ants’ nests again and again for weeks.  We were alarmed to read that some green woodpeckers will raid bee hives, so we have spoken to our beekeeper and he has reassured us the bees in our six hives are quite safe.

A fun fact is that ‘Professor Yaffle’, the wooden character in Bagpuss, was based on it.  It also has English folk names of rain-bird and weather cock as it is supposed to bring on rain.

At Wicor we have tried to make sure that we grow plants that are native and really helpful to wildlife especially in winter.  We have many holly bushes with berries on which the birds love (they also roost in the holly bushes as the spiky leaves give protection from predators) and positively encourage ivy, (Hedera helix), as it extends the season for our bees and has rich berries for the birds.  It also has really thick evergreen foliage which gives the birds shelter.   Along our main drive and in our coastal bed, we grow (and propagate) tuft forming grasses like Festuca gautieri which has fluffy seed heads through autumn and winter.  Lots of mini-beasts will hide in the grassy heads which the birds love too.  All around our grounds we have planted many, many native trees (120 last winter along including an elder grove and a nuttery) and we have lots of sorbus.  The elder, rowan and hawthorn trees around our site are really popular with birds providing lots of berries well into the cold, dark days.  Along one of our fences we have grown cotoneasters and pyracantha, which have lots of berries like the sorbus.   Among our many trees we have lots and lots of silver birches which are really beautiful especially the catkins and silver bark.  They are special trees as they keep producing catkins with seeds in during winter and many birds eat from them as they dangle from the branches.

During our grounds days we always think of the wildlife, and we harvest excess seeds all through the year.   We use fallen cones from our scots pine trees as structures for fat balls and pack them with the nutrient-giving seeds collected earlier.   We will be carrying on stuffing these cones for the rest of the winter, helping the feathered visitors to our grounds survive the cold.

Germinating Mistletoe

Germinating Mistletoe

We decided it would be interesting to try and grow some mistletoe at school, and as our Head Teacher had successfully cultivated some from seed at his home he helped us with the process.  February and March also happen to the best months for doing this.

Before we implanted the seeds, we decided to find out a bit more about this plant.  Mistletoe, Viscum album, is an evergreen plant and bears lots of cloudy white berries from winter to spring as well, which will help the wildlife in the grounds during the cold months.  If the mistletoe doesn’t produce berries, but flowers instead then it is probably masculine.  We also found out that mistletoe is semi-parasitic and lives on the water and nutrients from a host tree.  We thought that mistletoe would kill the host tree, but apparently it does not.  By introducing mistletoe to our grounds, we will be increasing biodiversity.

According to data from the National Mistletoe Survey cultivated apple trees are the favourite host for mistletoe, followed by lime and hawthorn – all of which we have at Wicor Primary School.  We also learnt that gardens are the favourite place for mistletoe to grow as there is more light than in woodland. 

From this information, we decided that our orchard, which has 15 heritage apple trees in and three lime trees would be the perfect place to cultivate mistletoe.  So on a dull, grey and wet February Friday we went to the orchard with Mr Wildman, our Head Teacher, with mistletoe berries from his garden.  He told us that we needed to rub the white berries onto the exact part of the tree where you want it to grow.  We thought that you might have to make a cut to rub the berries into, but according to Mr Wildman, it will stay where you rub it, as the inside of the berry is very sticky and it sticks to the healthy bark surface.  We thought it was really clever that birds help with the dispersal of mistletoe seeds because they get stuck to their bills. 

When the birds wipe their bills on tree branches, to remove the sticky substances, they are dispersing the seeds.  Blackcaps, Sylvia atricapilla, are really good at this and they are visiting the south of England even more these days which will mean more mistletoe!

Our research also told us that these berries are loved by birds including mistle thrushes Turdus viscivorus, redwings Turdus iliacus, waxwings Bombycilla garrulus and fieldfares Turdus pilaris.  Unfortunately, mistle thrushes are not very good at helping with the seed dispersal of mistletoe as they eat the berry whole and excrete the seeds missing the branches!  Mistletoe is also a really good habitat as well as a food sources: the mistletoe marble moth uses the leaves as a place to lay its larvae, and is a priority species.

 We will be keeping an eye on these seeds and hope to see if they have germinated later in the season.

Wicor Frosts

Winter Frosts

At Wicor Primary School we are encouraged to go outside in all types of weather, so a week of hard ground frosts (when the temperature of the ground falls below freezing point 0ºC/32ºF).

The cold weather has not stopped us from observing our grounds and finding out what happens to some of the animals in it, although the frosts do not seem to have bothered the triceratops in our Jurassic bed.  

It has certainly been very beautiful in the mornings, with many of the plants looking like they are wearing jewellery.  We have lots of grassy habitats at Wicor and although frost does not damage the grass, we found out that pressure on frozen grass causes the leaves to fracture and then ruptured cells can seriously damage it.  Knowing this it is amazing that our grass survives seeing as it has hundreds of feet stampeding on it every day!  We also compared a holly leaf to a frozen one under the microscope to try and see the differences.

Our pond has frozen over twice in the last week and in the past we have broken the ice thinking this would help.  However, new research by the conservation charity ‘Pond Conservation’ has shown that most wildlife in garden ponds will survive a pond freezing over if it is left alone.  Apparently, breaking a hole in the ice makes very little difference to the oxygen levels in the water and plants will also carry on photosynthesising under the ice.  We have therefore decided to just net the leaves this winter to stop them falling into the pond and turning into silt – this is a mucky job and so there are plenty of volunteers.

During the rest of the year, we regularly dip in the pond to see what is living in there, so we know we have long bodied dragonfly nymphs, smooth newts ‘Lissotriton vulgaris’, stags horn snails, common toads ‘Bufo bufo’ and common frost ‘Rana temporaria’, as well as pond skaters and water beetles.  Damselflies are also regular visitors. 

So this week we decided to investigate further and find out what happens to the frogs in our pond over winter.

Apparently, all frogs and newts (amphibians) in the UK must hibernate to survive the winter and frogs do this by lying dormant in compost heaps, leaf litter, underground tunnels or log piles.  So we have provided lots of winter habitats around the pond for our frogs including log piles all stuffed with fallen leaves.  There is also a large bug hotel made of pallets which they might like to overwinter in, and two small decking areas, where we sit and sketch, that provide additional shelter.   All of these areas let the frogs hide from predators and enter hibernation.  This is when their body functions slow down to a minimum and their bodies freeze.  Most creatures cannot survive this so the frog is the greatest toughie!  Sometimes frogs will prefer to overwinter in the bottom of the pond, where they will bury themselves in mud, and the temperature is slightly warmer.  They will be fine there unless the pond freezes over for a long period of time.  As ours has only been frozen for four to five hours at a time we think the frogs will be fine.

We were surprised to find out that frogs might even come out of dormancy to forage in milder periods of weather, so we will be on the look out for that in the next few weeks.

Badger behaviour in winter

Meles meles by Freya Y5

Badger 'Meles meles'

Habitat:  Badgers can be found in deciduous woodland, farmland, some urban gardens and coastal cliffs.  So they like to come into our grounds at Wicor Primary as the variety of areas (woodland, pond, orchard, field, scrub) supports their food chain.  

During our research on badgers, we found out that they do not hibernate in the sense that hedgehogs do.  Like many other animals and birds, badgers eat as much as they can during the autumn, laying down a lot of fat under the skin and increasing their weight by up to 6%. This helps them to survive through the winter. They do not hibernate but spend the coldest weather sleeping in their setts, living mainly off their fat.

Badgers are omnivores ( meat and plant eaters): they like to eat frogs, slugs, beetles and wasp grubs with earthworms being their main food, this can be hard to source when the ground is often frozen. . In the autumn we have a lot of food in the grounds for the badgers as they will forage for windfall apples, blackberries and wild cherries among other things.  Coming into the spring badgers also like to eat young rabbits and bluebell bulbs, and we have a lot of the latter.

Winter also plays a part in their breeding season with badgers mating between February and October but the fertilized egg does not start developing until December. This is called delayed implantation. Badgers usually have two to three cubs in a litter, and these are born mid-January to March which is about eight weeks after implantation. Badger cubs stay underground until they are 8 weeks old and at 12 weeks old they start the process of weaning.  

At Wicor we have had badger activity on site for as long as the school has been built here which is over 50 years.  We often see the trails they leave across the site to their setts in a neighbouring undeveloped plot of land, and if you follow the trails you would find three parts of a wire fence which they have pushed up to go between the school field and the field next door.  There is also a hole which has been pushed under a fence into the orchard.   There is an entrance to a sett on the field in a big mound of earth with evidence of scraping around the entrance which we think shows that they are going in and out.  The field next door has a network of at least three setts and we are supporting the community battle to save this undeveloped piece of historic countryside.  We even wrote a letter and went to the Fareham Borough Council at a hearing to appeal - after all we are the next generation and we want green fields not new houses.  But back to the badgers...we regularly find tufts of black and white wiry hair caught on low lying branches and on the fence that divides the school from the field.   We also have badger latrines that appear all over our orchard and we often put our feet in them accidentally while walking through the maze path in the orchard...but we find this really funny.  We think it is really clever that the badgers dig out latrines and this shows how clean they are.  We also found out how to tell the difference between male and female badgers: males can usually be distinguished from females by their broader, more domed heads, fuller cheeks and thicker necks.  The females also have shorter broader ones.

As part of our seasonal learning we will be keeping an eye out to see if any bedding material is pulled out of their sett entrance to air, which badgers do in the winter.

Deadly females

At this time of year there are lots of spiders around our grounds.


When we found a small spun mass we thought was created by a spider, we decided to learn a little more.


This is a cocoon spun by a female spider to protect her eggs. The male spider doesn't stay around for long for fear of being eaten! The spider that has laid this is a common garden spider 'Araneus diadematus'. Her size is approximately 18mm and she will swell up full of eggs before laying them in this cocoon.


She will eat butterflies, wasps and flies but won't eat smaller prey such as greenfly. A baby spider is called a spiderling.


Other common names for her include cross spider, European garden spider and garden orb-web spider.




The eggs look like mini ping pong balls.

Green tomatoes

Green Tomatoes


Tomatoes come in all shapes and sizes.
Some can be green, some can be lean and some look very mean!

Green tomatoes can be used to make a lovely chutney, please try our recipe.

Tomato chutney
Makes 4 x 150ml Jars

600g green tomatoes, roughly chopped
1 large red onion,sliced
4 cloves garlic, roughly chopped
10ml olive oil
3 teaspoons chilli powder
250g soft brown sugar
300ml white wine vinegar
125g pitted dates, roughly chopped
3 tablespoons salt

Sprinkle the tomatoes with the salt and leave for around an hour. Pour off any excess juice. Put the onions and garlic with the olive oil in a saucepan and soften over a medium heat for about five minutes. Lower the heat, add the chilli powder and sugar and give them a good stir before adding the tomatoes. Pour in the vinegar and stir to ensure the sugar dissolves. Bring the mixture to the boil, then reduce to a simmer and stir in the dates. Simmer for about 40 minutes,stirring regularly and checking that it does not stick to the bottom of the pan. You will be able to see when it is cooked as it will be pulpy and have a hint of runniness. Allow the chutney to cool and then spoon into sterilised jars.

Enjoy!

What we love about Wicor grounds...

Chickens and Bees

"We are just so lucky that we have a wide variety of wildlife in our grounds including chickens and bees. Our chickens are very important to us and we sell their eggs to our local community."
Trinity





Wildlife

"At this school we grow varieties of plants that attract lots of different insects and animals. We also have an expert on plants and animals so we know when to plant the plants and how to work with them."
Jasmyn









Orchards
"I love the fact we have an orchard with 13 different varieties of apple trees. The smell of sweet fresh fruit is really strong in the autumn. When the apples are ready to pick we like to taste, cook and even sell them to our school community."
Eliza


Our allotment
"We are very lucky to have such a wonderful allotment at our school. In our allotments we grow lots of plants all from seed, so we can watch the whole of the cycle in which it grows. Our allotment is full of different types of plants. We love going outside and enjoying our allotment."
