Isn't this just lovely? The Guardian reports on a series of stamps Sweden has produced, one of which features Greta Thunberg with swifts. It's 'part of a set by the artist and illustrator Henning Trollbäck titled Valuable Nature. 'The series ... features some of the 16 environmental quality goals recently drawn up by the Swedish government, including habitats designated as important to protect, said the national postal service, PostNord.' (If only ...) This came to us via our speaker on Thursday this week (21 January), Edward Mayer, the UK's leading expert on swifts. This will kick off our campaign to increase the number of swift nest sites in our area. Go to Talks for more details, and how to register for the talk. To get you in the mood, here's an amazing video of how swifts really do live their entire lives on the wing. Chairman Peter Shallcross comments that mid-winter when everything seems to be asleep seems to get shorter each year so we easily miss the birds who come here to escape even worse weather to our North, some of which like this fringilla montifringilla provide a welcome splash of colour. But how did it get that name and what do we usually call it? Andrew Graham reveals all on our MoreNews page, and says good places to see them would be beech woods, perhaps near Compton Abbas airfield or nearby Melbury Wood - if only we could get there in the current COVID lockdown. Chairman Peter Shallcross has commented that January is a time for regeneration and reflection: in the middle of winter trees are at rest and there are very few signs of spring to be seen as yet.
Unlike the trees, we at Tisbury Natural History Society aren't resting at all - in January we have not one but two of our monthly meetings On Thursday 21 January as Bob Gibbons cannot now tell us why the Isle of Purbeck is so special (but he'll be back next January), we are delighted that Edward Mayer, the UK’s leading expert on the conservation of Swifts (the Common Swift: Apus apus) will be talking to us. And on Thursday 28 January, we will have a 'Meet a farmer' discussion online at 7.30 pm with Neil Harley, an experienced farmer from the Salisbury Plain who has recently acquired land near the community fields behind the Nadder centre. Full details on both these and instructions on how to register for Zoom, go to our Talks page. Also known as Fringilla Montifringilla. Andrew Graham explains that its scientific name means 'mountain finch' so my thanks to him especially for that. He continues: ' Its name originates from Common West Germanic - brâma meaning bramble or a thorny bush.' This is a bit confusing - perhaps we should call it the 'mountain bramble bird'! 'This attractive bird is a winter visitor, similar in size and shape to the chaffinch. Bramblings are gregarious and often join up with flocks of chaffinches. They have a black head and mantle and orange patches on the breast, shoulder, and throat. Underparts are brown and wings are black with white and orange bars. Females are duller than males [but I think the female on the NewNews page is very pretty - Ed] and juveniles are like females with dark head and grey cheeks. Birds moult after breeding so their plumage is at its freshest in Autumn and Winter. By January, the buff tips on the feathers have been worn off and the breeding plumage so achieved is at its most distinctive. In flight, the bird shows a long white rump, and this is a key to identification, but beware of confusing it with the plumper bullfinch (unlikely to be found in flocks of chaffinches). Bramblings arrive in the UK in autumn with numbers building from September onwards. First arrivals are seen on the east coast, arriving via the continent to avoid long crossings over the North Sea. They then spread inland to all parts of England, Wales, and lower lying parts of Scotland. They will start leaving from Feb to March onwards and all will have returned to their breeding grounds in Scandinavia and north-west Russia by May. One or two pairs occasionally nest in highland Scotland.
Bramblings feed on berries, insects, and seeds but particularly on beech mast. The numbers that arrive here depend upon the amount of mast available in Scandinavia and on the continent. In good mast years relatively few will arrive but if food is scarce or winter weather particularly bad, large numbers may reach us. Perhaps variations in food availability makes brambling migrations unpredictable: birds that winter in the UK one year have been found in Italy the next. Bramblings come into gardens and visit bird tables but usually only during the harshest weather. The best place to look for them is moving through beech woods or on farmland fields nearby. Beechwoods near Compton Abbas airfield and Melbury Wood are promising locations. At this time of year, it is worth checking any flock of finches. On the continent they may form huge flocks, some roosts have been estimated to contain over ten million birds. Just to put our efforts in context, Channel 5 is running a 4-part series on the Natural History Museum in London - full details here. We know all about fossils of course, being next door to the Jurassic Coast, the Etches Museum et al. But getting to see 'the unique and rare pieces too valuable to exhibit' sounds like a bit of a treat.
First of the series is Thursday, 7 January, 8 pm and of course on catch-up. Then, by way of coming right up to date, Messums Wiltshire's 'Conversations' series includes Isabella Tree, at 6.30pm on Wednesday, 27 January. You can access this via www.messumswiltshire.com/members-area - annual membership is £30 for an individual, £50 for a family. Isabella will talk about her now famous re-wilding of her family estate in West Sussex, described in her book 'Wilding'. |
