Bugs, Birds and Beasts in the East

All of our up to date fun and frolics in the East from office antics to great conservation stories and those magical connections with nature.
  • Welcome Back to your Best House Guest!

    I don't know about you but I love this time of year, when the grey skies give way to a more confident blue and I get the growing feeling that spring has settled in, and summer truly could be a possibility! It’s around about now that we welcome well known summer migrants back to our shores, including screaming tangles of soot black swifts.

    As they soar enthusiastically into our neighbourhoods as if our island were a great big airport terminal, I feel a great sense of freedom, experienced vicariously through their playful loops and aerial tricks. Their agile flight is unsurprising, as swifts spend most of their time on the wing and even sleep whilst in the air!

    However, as their joyful sound resonates across our towns and villages, after an incredible 3,000 mile journey from Africa, swifts arrive to face a housing crisis here in the UK.   Swifts have declined by an alarming 38% since 1995 and are now an amber-listed species on the list of Birds of Conservation Concern.  Whilst we don’t know the exact cause of their decline, the loss of nest sites in the UK is likely to be at least partly responsible.

     

    The good news is that if you are going to have company for the whole of the summer, you couldn’t get better house guests than swifts. If they were to answer a ‘housemates wanted’ ad they would be very clean, stay only 12 weeks per year and be very helpful in getting rid of mosquitoes and other flying insects.

     

    When they arrive back in the UK they return to the exact same location year after year. Swifts like to nest in the rooftops of old buildings but renovation and development often destroys suitable sites.

     

    Their nests are minimal, made from stuff they collect in the air, such as feathers, paper, straw, hay and seeds. These materials are cemented with saliva and used to build a nest in open eaves, under loose roof tiles and in holes in walls.

     

    Here at the RSPB we have a team of conservation officers that encourage planners, developers and statutory bodies in the East to incorporate swift friendly features into new developments. We recommend the use of special ‘swift bricks’, which are simple brick like structures swifts can nest in that are built into buildings.

     

    However, you don’t have to work for a conservation organisation to do your bit. To keep swifts the poster boys and girls for summer here in the UK, we can all do something to help.

     

    What you can do to help swifts this summer

    • We need people to send their swift sightings to the RSPB Swift Survey at rspb.org.uk/swift survey. This will provide essential data on swift nest site locations to assist planners and developers to protect and enhance swift colonies.
    • Leave existing nest sites undisturbed and avoid working on walls or roofs with swifts nesting in them during the breeding season, May to August inclusive.
    • When repairing or restoring a roof keep swifts in mind: make sure new access holes match the location of the old ones.
    • Never disturb swifts at the nest.
    • Put up swift nest boxes at home – you can even play swift calls to attract them!
    • Comment on local planning applications, asking your local authority to protect and provide swift nesting places.

  • What’s all the noise about?

    Last month in this column I wrote about the urban dawn chorus I enjoyed one morning as I made my way through the city to work. This month I find myself irresistibly drawn back to the subject of feathered songsters, this time to shed some light on nature’s sopranos, tenors and baritones.

     

    The dawn chorus may sound like a frantic melee with the most beautiful voices with the birds competing to get their voice heard, but there is method in the madness and the singers know exactly when their slot is and if you listen regularly you will start to recognise certain species habitually starting before others. So, without further ado, here is a very brief guide that will hopefully help you start to identify who’s who in the choir:

     

    Act one: robins and dunnocks

    Act two: blackbirds, songthrushes and skylarks

    Act three: chiff chaff, chaffinch, wood pigeon, and collared dove

    Act four: blue tits, long tailed tit, great tit, goldcrest and tree sparrows

    Act one

    Dunnocks and robins are among the earliest to warm up: to hear the first act you’ll need to be in the stalls early as they start to sing about an hour before sunrise.

     

    Act two

    Blackbirds and song thrushes come hot their heels, probably because the ground is wetter in the morning so worms are more active and the ground is softer.

     

    Act three

    Finally, contributing to the crescendo, wrens, tits and warblers come in, with the tiny call of the goldcrest on the stage too. These later arrivals to the choral scene eat insects and are perhaps more sensitive to the coldness of dawn.

     

    Act four

    Unbeknown to many there is also an evening performance, with a chorus at dusk, but it’s much quieter, and it’s easier to hear birds like blue tits and tree sparrows. They sing in the morning too, but we are less likely to notice them among the cacophony!

    Summer migrants join the chorus

    As the breeding season approaches its peak, migrating birds like cuckoos, nightingales, turtle doves and warblers returning to this country for the summer will join the chorus of resident blackbirds, wrens, dunnocks and robins.

     

    If you’re lucky enough to live in area with farmland, woodland or reedbed nearby, you might hear the unmistakeable songs of some of these traditional heralds of summer. Otherwise, an early morning visit to one of Norfolk’s many nature reserves is a great way to track down these more elusive songsters.

     

    Nightingale solo

    Male nightingales prefer to sing alone, turning their performance into an all-night after-show, singing until sunrise. They can’t rely on visual clues to attract a mate so their song is particularly important and they can’t risk it being lost among the other voices.

     

    What’s all the noise about?

    At this time of year, birds are in the market for a mate for the breeding season. Male birds establish a territory- an area they will defend against competing males of the same species- using their song both to stake their claim and to attract a female.

     

    They are at their loudest early in the morning, which is not a good time to go foraging for food if you’re looking for insects and relying on sight to find them.

     

    The louder your dawn chorus the more proud you can be of your efforts to give nature a home too. If you’re providing food, water and shelter, it is bound to make their voices as strong as possible!

     

    Singing is hard work, so it is usually the fittest, best fed males who sing the loudest. In many cases, once a female has been serenaded the male will sing less often as his work is done.

  • Enjoy Gardening and add a Splash of Colour!

    Everyone is taken by a different aspect of nature. Some quest to see as much of it as they can, ticking off myriad species as they go. Others are wedded to particular creatures, developing a strong allegiance in the form of sponsorships, cuddly toys, perhaps even taking a once in a lifetime adventure to spot them. I know people enraptured by the fluffy and others enthralled by the feathered. Me? I am quite simply enchanted by anything that grows in the fields, flowerbeds and forests around me.

    In particular, at this time of year, I love the feeling of delighted surprise that I get when I first realise that the cherry blossom tree in my front garden is in bloom. In what feels like an instant, the tightly packed buds burst into frilly existence, like floral popcorn, signaling fresh life and new beginnings.  Somehow my tree blossoming has become symbolic of the joyous potential held bud-tight, ready to unfurl in the months ahead.

    Ask anyone about the nature moments that really fire them up and they’ll probably all say something different, however we are all united by the simple fact that whatever you love about nature, it has a hotline to our heart.

    I feel soothed by the gentle green of buds and shoots, I feel a genuine optimism as the world fills with colour, slowly erasing the grey of winter and I feel hope as I look closely and see just how many creatures are enjoying the new growth as much as I do. Bees are filling their knees with pollen, the first few butterflies of the season are tentatively supping nectar from the brave early blooms and birds are busily house hunting amongst the branches.

    For those of you, like me, craving a summer of growth, one of perfect things to get on with in the wildlife-friendly garden at this time of year is sowing seeds.

    There's little more satisfying than poking a few seeds into some pots of compost (peat-free, of course!) and tending the seedlings as they emerge. How is there so much energy and knowledge packed into those tiny, lifeless packages?

    The RSPB’s wildlife gardening expert, Adrian Thomas, gave me some tips on his favourite hardy annuals for wildlife to be sown outside directly into the flowerbed – he guarantees us that if we grow a good patch of these, come summer, the butterflies and bees will be on their way!

    And if sowing from seed seems a bit too much, you can always head to the wildlife friendly plant section in your local garden centre and buy them fully grown!

    Echium vulgare Blue Bedder: With short, crowded spikes of violet-blue flowers, magenta flushed when fading, and pink buds, this plant, also known as ‘viper’s bugloss’ is very attractive to pollinating insects.

    Cosmos bipinnatus: Considered a half-hardy annual, although plants may reappear via self-sowing for several years. The cultivated varieties appear in shades of pink and purple as well as white and will flower through the summer and into autumn.

    Cerinthe major: With blue-green leaves and tubular yellow and purple flowers, ‘honeywort’ is a winner with wildlife.

    Phacelia tanacetifolia: In bloom, the ‘fiddleneck’ will reward you with an abundance of densely set soft blue or lavender-blue flowers through summer and autumn.
