How to… Make Your Own Bird Nest Box

/ Laura Tuke / Leave a comment

As our summer visitors, such as Swallows and Willow Warblers, leave us for sunnier shores, and we wait for our winter returnees, such as Redwings, the world outside our doors is slowing down and wildlife is preparing for the colder times to come. Autumn is a time for extraordinary spectacles, storing up food and changing colours, but also a time for us to do our bit, to help our wild neighbours with their preparations, and to prepare for a new year to come. This can range from cleaning ponds and putting out food, to planting trees and creating wood piles. It is also importantly a time to provide new homes for nature.

Previously, in spring/summer I posted on my blog about how to make a home for nature in the form of a bee hotel (see How to… Make Your Own Bee Hotel). A bee hotel is aimed at providing solitary bees (90% of UK bee species) with a place to nest, and for my blog I made a bee hotel that has now had some success. There are other forms of homes that we can make for wildlife though, for example for different species of bird.

In the UK, more than a quarter of all bird species are of the highest conservation concern, with a decline in breeding birds (44 million) between 1967 and 2009. This means that conserving and creating habitat for birds is an important issue, and something we can all get involved in. One example of an easy way is to put up nest boxes, which mimic natural habitat. They create an effective artificial cavity for birds, providing an accessible alternative for species that are currently experiencing the loss of breeding habitat and winter roosting sites.

Nest boxes come in a variety of shapes, sizes and designs, which will depend on the species of choice and the purpose they need to fulfill. Though you can put up a nest box at any time of year, the best time is right now, ready to be used as a roosting site throughout winter and for breeding in the spring. This way you can increase the chance of your nest box being a success next year. There are no set rules though, so why not try making your own today!

How to Make a Bird Nest Box

What you need:

  • A plank or offcuts of untreated wood, about 15mm thick for insulation
  • Tape measure & pencil
  • Hand or power saw
  • Drill & different sized drill bits
  • Sand paper
  • Hammer & nails
  • Screws
  • Sealant, a piece of rubber or something similar
  • Optional: Hole plate

Step by Step Guide:

  1. Decide on your nest box design. Your nest box will most likely be aimed at a certain species, such as Robins or House Sparrows. You can also choose particular design features, such as a flat or apex roof. For the purpose of this guide though, I will provide instructions to make a standard Tit nest box.
  1. Use a tape measure and pencil to mark out the wood you need, either by creating templates out of paper or cardboard, or by drawing straight onto the wood. For this design you will need 6 pieces: a back (45cm x 15cm); a base (11cm x 15cm); a front (21cm x 15cm); a roof (20cm x 15cm); and 2 side panels (25cm high at the back, 20cm high at the front, and 11cm wide). Use a hand or power saw to cut the wood into the 6 pieces needed.
  1. Next, take the front panel and use a wide drill bit to make a hole towards the top of the panel, at least 125mm up, which the birds will use to enter the nest box. The size of the hole will vary between different species, but for my nest box I made a 25mm hole, aimed at Blue Tits and similar Tit species.
  1. Use sand paper to sand down any rough or uneven edges of the wood, that otherwise could cause problems for birds using the box.
  1. Use a hammer and as many nails as you need to make the back, base, sides and front fit together forming the main body of the nest box. It is often best to mark where the nails will go first and partially drive each nail through the first piece of wood first (e.g. the back), which will make nailing the pieces together easier and help avoid splitting the wood.
  1. Attach the roof to the box using screws that you can later remove when needing to clean the nest box out. Seal the gap between the roof and the back of the nest box with either flexible sealant or an attached flap of recycled rubber.

Optional editions: Add a nest box hole plate to the front of the box to prevent predators from enlarging the nest box hole and larger bird species using the box. Also, you could apply a water-based wood preservative product to the outside of the box to prolong its life and help to repel water.

Tips on putting your nest box up

  • Unless there is shade during the day, position the nest box facing between north and east to avoid strong sunlight.
  • Choose a location which is 2-4 metres above ground level, out of reach of predators, and away from constant disturbance.
  • Make sure there is a clear flight path to the entrance of the nest box and that there is shelter from bad weather.
  • Place your box away from the location of any other nest boxes to reduce the chances of competition.
  • Avoid using nails to attach the box to a tree, as they may cause harm. Instead try to tie the box to the trunk or hang it, or otherwise use stainless steel screws or nails that do not rust.

Enjoy!

How to… Make the Most of Autumn’s Bounty

/ Laura Tuke / Leave a comment

Leaves rustling beneath my feet, golden, russet, auburn. Crisp, dewy mornings, adorned with misty tendrils and spider’s webs. Hedgerows hung with bright berries, and woodlands dotted with fantastical fungi. Cosy nights in, whilst the night comes alive with Tawnys and foraging mammals. Lazily buzzing insects, murmurations, Red Kites soaring, waders and wildfowl, and endless wonder.

Autumn means different things to different people, but it is deep rooted in the natural world around us. A season of reflection and change, it is the favourite season of many. Some people celebrate turning a new leaf, some the drop in temperature and cosiness that comes with it, some the festivities, and others celebrate the little things, from migrating birds to reconnecting with nature. To all though, it is a bountiful season, marked with plentiful food and the first whispers of winter.

Historically, autumn is associated with harvest time and bringing in the food of the land before winter. From corn dolls to harvest festivals, autumn is symbolic in British tradition and culture. It has been inspiration for poets and writers alike including Keats (‘Season of mists and mellow fruitfulness’) and Jane Austen (‘the thousand poetical descriptions extant of autumn’). It is an important time of year to check in with the status of wildlife, whilst also being a time of spiritual significance for many.

As temperatures begin to drop and the leaves begin to change, it is time for us all to get out there, watch amazing sunrises and sunsets, forage for food, and stay connected with mother nature. With autumn being deep rooted in what lays outside our doors, here’s a guide to just some of the important species flourishing in autumn.

Autumn Species

Unless you are 100% sure of what something is and if it is edible, then do not eat it! Also, harvest only what you need and leave the rest for wildlife!

Hazel (Corylus avellana)

  • Fruit: The popular hazelnut, an edible nut that begins with a thick-green husk, before ripening to a brown in autumn
  • For Wildlife: A favourite food of Grey Squirrels, Dormice and Wood Mice, amongst other species, often being cached for winter
  • How to Identify: Circular-shaped leaves with toothed edges and tapering to a point; coppery brown smooth to peeling bark; lemon-yellow catkins and tiny red bud-like flowers in spring
  • Autumn Facts: Until the First World War, Holy Cross Day on the 14th September was traditionally a school holiday, where children would go nut gathering

Bramble (Rubus fruticosus)

  • Fruit: The familiar edible blackberry that begins green, then turns red, before ripening to purple-black in autumn. Blackberry picking is a favourite part of autumn for many!
  • For Wildlife: The berries are a valuable food source for mammals, such as badgers, and small birds, such as Blackcaps
  • How to Identify: Oval-shaped leaves with toothed edges and tapering to a point; prickly and half-evergreen stems; white or pink flowers from spring onwards
  • Autumn Facts: Folklore in Britain dictates that blackberries should not be picked after Old Michaelmas Day (11th October), as the Devil has by then made them unfit to eat

Recipe:

Hawthorn (Crataegus monogyna)

  • Fruit: Hawthorn berries, sometimes known as haws, are edible but their single seed is toxic to humans. They ripen to a bright red, is likened to over-ripe apples in taste, and are used to make jams, jellies and wines
  • For Wildlife: Important source of food during autumn and winter for small mammals and birds, including Blackbirds and Redwings
  • How to Identify: Shiny leaves that are oval-shaped with deeply cut lobes; thorny stems and twigs; white fragant flowers with 5 petals fading to pink
  • Autumn Facts: One of the main uses of Hawthorn is to treat high blood pressure, widening blood vessels and increasing blood flow 

Blackthorn (Prunus spinosa)

  • Fruit: Produces edible, but tongue-numbing, sloes which are small blackish plums with a bluish powdery surface. Popular to flavour gin!
  • For Wildlife: A feast for birds in autumn and winter that help to disperse the plant’s seeds
  • How to identify: Oval-shaped leaves with toothed edges and tapering to a point; blackish, thorny stems and twigs; snow-white and 5-petalled flowers with red-tipped anthers in the centre
  • Autumn Facts: Sloes are rich in vitamin C and have been used to treat stomach disorders, blood purification, teeth whitening, and even gum problems

Recipe:

Pedunculate Oak (Quercus robur)

  • Fruit: Produces the familiar acorn, with scaly cups and clusters carried on long stalks. Contain tannins that are toxic and bitter to humans, but can be leached out to make edible
  • For Wildlife: An important rich source of food for species such as Jays, Mice, Squirrels and Badgers, often being cached for winter
  • How to Identify: Large, oblong leaves, broader at the base and lobed, turning brown in autumn; massive rugged grey-brown trunk and broad crown; yellow-green catkins in spring
  • Autumn Facts: The most important texts in British history, such as the Magna Carta, were written in Oak gall ink

Apple (Malus domestica)

  • Fruit: Though not native to the UK, domestic Apple trees produce the popular apple which is now cultivated across the globe
  • For Wildlife: Apples are not just for humans, being a popular food source for wildlife too. Birds, such as Thrushes, and mammals, such as Badgers, feast on the fallen and ripening fruit
  • How to Identify: Dark green and typically oval-shaped leaves with toothed edges, and hair underneath; flowers are five-petalled and pink to white in colour
  • Autumn Facts: Most apples are still picked by hand and the world’s top apple producers are China, United States, Turkey, Poland and Italy

Recipe:

Dog Rose (Rosa canina)

  • Fruit: Berries known as hips, that are edible, egg-shaped and bright red. Popularly used for a wide range of food and drink
  • For Wildlife: The hips are eaten by fruit-eating birds, such as Fieldfare and Waxwings, and small mammals, such as Bank Voles
  • How to identify: Dark green and oval-shaped with toothed edges and tapering to a point; arching stems with broad-based strongly hooked prickles; flat and fragrant white or pale pink flowers with large petals and hairless stalks
  • Autumn Facts: It is a valuable medicinal plant, with the hips being made into a vitamin C rich syrup for children (20 times the amount that is in orange juice)

Elder (Sambucus nigra)

  • Fruit: Juicy edible purplish-black berries, known as elderberries, that are used to make a variety of wines, juices, jams and jellies
  • For Wildlife: The berries are eaten by both birds and small mammals, from Whitethroats to Dormice
  • How to identify: Long, dark green oval-shaped leaves with finely toothed edges and tapering to a point; strong smelling bark that is corky and fissured; white, small and fragrant flowers in flat-topped clusters
  • Autumn Facts: One of the most commonly used medicinal plants across the world, from Native Americans using it to treat infections to the Egyptians using it to improve their complexions and heal burns

Recipe:

Spindle (Euonymus europaeus)

  • Fruit: Spindle berries are toxic to humans, with a laxative effect. They are highly distinctive, with 4-lobes and being bright coral-pink
  • For Wildlife: Provide food for a variety of species including mice, birds and even Foxes
  • How to Identify: Shiny oval-shaped leaves with finely toothed edges and tapering to a point that turn distinctively pinkish-red in autumn; deep green 4-sided twigs darkening with age; greenish-white 4-petalled flowers in clusters
  • Autumn Facts: Spindle is at its best and most colourful during autumn with warm leaves and berries

Breeding Barn Owls 2020

/ Laura Tuke / 1 Comment

Feathers fluffy, downy, soft to the touch. A heart of feathers outlining inquisitive eyes. A new beginning, hints of the precious adult to come. A hope, a prayer, a future. An endearing beginning for the reticent guardian of twilight – Original Piece

As a very unusual summer comes to an end, with it also comes the end of another breeding season for the Barn Owls that call my family’s farm home. For many years now, Barn Owls have increasingly become an important species on the farm, giving an indication of habitat quality and changes in the environment.

Last year the Owls had their best year yet, with two separate pairs on the farm, one nesting in a tree and one in a nest box, fledging two chicks each. It was also the start of Barn Owl chicks being ringed on the farm, which was very exciting for us all. If you want to read more about these Barn Owls, take a look at my previous posts, including Barn Owls in the Depths of Dorset, and Barmy about Barn Owls.

This Year

This year has been another year filled with the joys of this species. From sightings around the farm throughout the seasons, to fledged chicks during the summer, it has been really special. This year we were not lucky enough to have 2 known pairs breed again on the farm, but we were lucky enough to have 1 pair breed in our Barn Owl nest box. In the end the pair hatched 4 chicks, with 2 surviving to successfully fledge in August, which was exciting nonetheless. Though no Barn Owls have bred in the old oak tree this year, it has also been actively used, becoming a popular roosting site for one or more individuals.

Conservation Action and the Barn Owl chicks

Following our Barn Owl chicks being ringed last year, I have now joined the North Dorset-based Conservation Action group, becoming a trainee bird ringer. Conservation Action is a group of experienced ornithologists and BTO trained ringers, dedicated to conserving and preserving the natural environment, ringing bird species to increase knowledge, and raising awareness of conservation efforts in younger generations. Focuses range from migrating species in Autumn to Owls and my favourites, the birds of prey.

Last year Conservation Action monitored a total of 47 Barn Owl nest boxes across Dorset, leading to 66 Barns Owls being successfully ringed (63 owlets and 3 adults). It was a great year for Barn Owls and Conservation Action alike!

Now a member of Conservation Action and a trainee bird ringer, this year I was very excited at the prospect of Barn Owls breeding once again on our land. For this breeding season I got the opportunity to become an accredited agent under a Schedule 1 Permit, meaning that I was fully licensed to assist with Barn Owl nest box checks and monitoring, including our very own box. So it was an absolute privilege to be able to ring, under supervision, my very own 2 Barn Owl chicks this year. Such incredible birds and such a special experience, which was made all the better by getting to experience it alongside my parents and 2 year old niece!

Their Importance

Barn Owls are one important indicator species for farmland and grassland in Britain, meaning that they can tell us a lot about the condition of these habitats. With Barn Owls having made a comeback to my family’s farmland, it has also shown how changes to land management can restore and create habitat for wildlife, including for other species with related habitat needs (for more information see my post Giving Nature a Home on the Farm).

Barn Owls have also helped me to find out more about the small mammal species living on our land. This has been through dissecting pellets left by the owls, that I have previously written about in my post: How to… Be a Barn Owl Pellet Detective. For example, pellets from the roost tree have shown remains belonging to Bank Voles, Field Voles, Common Shrews, and Brown Rats, whereas pellets from the nest box barn have shown remains belonging to Field Voles, Bank Voles, Common Shrews, Pygmy Shrews, and Mice.

Moving Forward

After this year’s Barn Owl breeding season, and the excitement of Barn Owls continuing to breed on the farm, things are looking exciting for the future! It will be interesting though, to see how Barn Owls fared across Dorset and the UK this year as a whole, and to see if the farm’s 1 breeding pair followed the general trend. I also look forward to now getting more involved in monitoring Barn Owls in Dorset, spreading word of the work Conservation Action are doing, and the potential of ringing more of my own Barn Owls next year!

On the farm we now aim to continue working with Barn Owls and other wildlife in mind, and to monitor the success of new projects, including putting up nest boxes for Kestrels, Tawny Owls and Little Owls. In many ways the future looks bright to me!

How to… Identify Chalkland Wildflowers

/ Laura Tuke / Leave a comment

Colourful, radiant, buzzing with life, a piece of paradise in the summer sunshine. All words to describe a small piece of chalk habitat nestled within the heart of my family’s farm in Dorset. Amidst a clay-dominated landscape, this small creation aims to emulate the approximately 41,000 hectares of lowland chalk grassland that can still be found across the UK. This super rich habitat contains over 40 species of flowering plants in every one square metre, giving chalk grassland its reputation as the tropical rainforest of Europe! Sadly though, 50% of chalk grassland has already been lost in Dorset alone since the 1950s.

In 2017, my Dad made the decision to transform a small triangular area of land on our farm into our very own chalk paradise. Though we do not live immediately on chalk downland, it can be found to the North and South of us. This makes our location ideal to create stopover habitat or a wildlife corridor, for the myriad of species that rely on these diverse plant communities. Following bringing in 40 tonnes of quarried chalk and lots of wildflower plugs and seeds, we now have a thriving 10m by 3m and 2m in height chalk mound.

Though my family’s chalk habitat is still in its relative infancy, over time it is transforming into a wildlife haven. From Grasshoppers and Marbled White Butterflies to blue Butterflies and Carder Bees, new species are popping up each and every year. This mini habitat has also been a great place for my mum to teach me all about the plant species that call chalkland grassland home. With her inspiration, I have put together a simple guide to identifying just some of the many wildflower species that are appearing on our mound.
