Kingston on Soar, Sunday 28 December

A freezing, snow-covered scene appeared before Alex, Gary and I as dawn broke at Kingston. We thought the cold weather would hopefully pull in a few more birds to the feeders. The first net round produced a few birds but not as many as expected, catching then continued with just a few birds each round. We thought we would have had a bigger catch given the perfect conditions but we did get a nice variety with another new Jay and 3 Great Spotted Woodpeckers. The morning ended with a total of 28 birds made up of (new/retrap): Robin 2/0, Chaffinch 6/1, Blue Tit 0/1, Great Tit 1/5, Coal Tit 1/0, Goldfinch 1/0, Dunnock 1/0, Blackbird 2/0, Song Thrush 1/0, Redwing 1/0, Great Spotted Woodpecker 3/0, Jay 1/0.

Recent Recoveries

A couple of recoveries of some of our ringed birds have come in;

A Reed Warbler ringed at Holme Pierrepont in August this year was soon the move and was controlled by ringers in Hampshire ten days later.

And an unfortunate Barn Owl is the first of this year's young birds to be reported to us as a road casualty, after being ringed in Clifton wood in June. It met its end near Bingham, so hadn't travelled far.

And we have controlled a few birds too;

A Barn Owl ringed as a chick by Birklands RG near Newark sewage works in May this year, was controlled nearby in Hockerwood, Southwell in August. Another Birklands Barn Owl chick, ringed in July 2013 in Caunton, was controlled close by in Kirklington this October.

Two Sorby Breck birds reported by us were a Mute Swan, colour-ringed in Markeaton, Derbys, in August 2010 which was resighted at Attenborough in May this year. Then a Reed Warbler, ringed at Williamthorpe, Derbys, in August 2012, was controlled at Holme Pierrepont in July this year.

And finally we controlled a Chiffchaff in September this year at Holme Pierrepont which had been ringed as a youngster in August 2013, near Ripon in North Yorkshire.

Kingston on Soar, Saturday 13 December

A beautiful winter's morning broke as we set nets for the first time at the new Kingston on Soar feeding site. We put up just 2 x 6m and 2 x 9m nets and made a base a short distance away. The first net round produced a good catch and the next and again the next. We were pleasantly surprised by the numbers caught, to have been perfect it would have needed a bigger range of species. But the team of Sue, Tom, Alex, Alistair, Gary and I were happy enough with the final total of 72 all new birds (I’m sure that the next visit will include a good number of retraps!).

The total comprised: Treecreeper 1, Long-tailed Tit 11, Robin 2, Chaffinch 15, Blue Tit 20, Great Tit 16, Goldfinch 3, Dunnock 1, Blackbird 1 and Jay 2.

It was surprising number of tits in this farmland site, especially as there were no peanuts or other such favourite food of tits but as the winter goes on the site will hopefully pull in more farmland species. The two Jays were unexpected and managed to bring a little blood to the fingers of Tom and Sue! We were also joined for the session by potential new trainee, Jack.

Granby, Sunday 7 December

Saturday would have been the better day to have gone out this weekend, but I wanted to show the Notts Biodiversity Action Group 'scrub-bashing' party what we do. About 20 of them were out to cut re-growth from last winter and do more clearance work on the Bingham side. This is all to encourage the Grizzled Skippers to move along the line from the Bingham Linear Park, where it is close to its northern limit in the UK.

Weather wise, it was windy with a mix of sun, cloud and showers; bit like April really! This affected the catch as not many birds were moving around (particularly Yellowhammers). I suspect they lie low as beating against the wind would burn a lot of calories. Nevertheless we managed 41 birds, which was dominated by tits & Chaffinches. The majority of the retraps were from last winter, bar a Chaffinch from 2012/13, Great Tit and Yellowhammer from 2011/12 and a Blackbird from 2008/09.

Captures were (new/retraps) 41(18/23): Blackbird 0/1, Blue Tit 6/8, Chaffinch 10/2, Dunnock 0/2, Great Tit 0/8, Redwing 1/0, Robin 0/1, Yellowhammer 1/1.

Recent Recoveries

The interesting recoveries continue, as a first winter female Chaffinch ringed at Brackenhurst in March 2010 was seen knocking about the Netherlands in October this year. That's a movement of 361km, 4.5 years after ringing. The ring was read in the field, which is quite an achievement considering the size of an A-ring and demonstrates the importance of placing the ring so it can be read in the field, no matter what size it is!

And a Tawny Owl that was ringed as a chick in Plungar 9 years ago, in May 2005, was picked up sick or injured in nearby Orston in November this year. See the earlier blog post for further information http://southnottsringinggroup.blogspot.co.uk/2014/11/tawny-owl-recovery.html

Other recoveries are as follows -

4 ill-fated Barn Owls first:

• a bird originally ringed as a pullus in June this year in Upper Broughton was found dead 8km away in a building in Wymeswold 4 months later
• a bird ringed in June this year as a pullus in Moorgreen, was killed on the roads around Lincoln 5 months later having travelled over 50km
• one ringed in Shelton this June as a pullus was found just 4km away in Hawksworth in August, having been partially eaten
• and another June bird, ringed as a pullus in Muston, Leics, was found dead 3 months later, 31km away in Beeston, another road casualty

Then a Tawny Owl that was ringed as a pullus in May this year was found dead in nearby Norwell Woodhouse, in October.

Birds we have controlled are as follows:

A Barn Owl originally ringed as a chick by North Notts RG in Edingley in June 2013 was found dead 10km away in Caunton in February this year.

A Little Owl ringed in June 2013 as a chick in Hoby, Leics, was controlled by us in Tithby, 17km away in May this year.

And a Kestrel ringed in July 2011 as a pullus by Sorby Breck in Pilsley, Derbyshire, was found without its head in an owl box in Lowdham, in June this year, having travelled, one way or another, 30km from its birthplace.

On the value of ringing again

A post by Dave Leech on Mark Avery's blog which is worth a read:

Treecreepers

Today I retrapped a Treecreeper which was originally ringed in January 2013 and aged as a first winter bird (age code 5). According to the Identification Guide to European Passerines by Lars Svensson there is a “difference in the size and shape of the pale tip on the outermost long (3rd) primary covert, adults having smaller and more rounded tips, young birds larger and on average more drop-shaped or wedge-shaped pale tips”. However he does recommend more testing of this method.

Today's bird supports this aging method. Below is a juvenile bird for comparison.

Brackenhurst, Sunday 30 November

A fine, bright sunrise met us this morning at Brackenhurst to herald in St Andrew's Day. We were nine (I thought about holding the AGM!) and included Alex, David Roberts, Duncan, Gary, a resurgent Libby, Nick, Sue, Tom and myself. The weather stayed bright and dry and backed up to a north easterly breeze as forecast. When will it get cold enough for all the trees to shed their leaves? I think we have enough leaf extracting experience now.

Catching was slow at the feeders, but nice to have the first four Yellowhammers of the winter. The weather needs to get harder to bring them in greater numbers. Orwin's again produced a large tit flock with 26 birds in one net round. This included 14 retrapped Long-tailed Tits of which half were from the last two winters. A small sample, but maybe indicative of higher survival rates with very recent milder winters. All the other retraps are from the same time frame.

Captures were (new/retraps) 81(39/42): Blackbird 1/0, Blue Tit 5/5, Chaffinch 9/2, Dunnock 1/1, Goldcrest 0/1, Greater Spotted Woodpecker 1/0, Great Tit 6/17, Long-tailed Tit 0/14, Redwing 7/0, Robin 2/2, Tree Sparrow 1/0, Wren 2/0, Yellowhammer 4/0.

Tawny Owl recovery

Back in 2005, Jim ringed a brood of 5 Tawny Owls in a box in Plungar - still the only brood of 5 he's ringed. One of these chicks has just been found sick in Orston and handed into a Bingham vet 9 years later!

Recent Recoveries

We have had some more birds controlled by others over the past few months, as well as a number controlled by SNRG members.

A couple of non-barn owls first: a cormorant which was ringed as a chick in April last year was reported from its colour rings at Priory Water near Melton Mowbray in October this year. The colour rings must be distinctive as it has also been sighted at Cossington a couple of times in March and September.

A Sand Martin, ringed as an adult in May this year near Ratcliffe-on-Soar was controlled by us at Newthorpe a month later.

And 7 individual Barn Owls:

One ringed in Bunny as a chick in July 2011 was found dead as a road casualty in nearby Wymeswold this October.

A bird ringed as a chick in Collingham in August 2012 was retrapped by North Notts RG in Sutton-on-Trent 2 years later in August 2014.

North Notts controlled another bird in Sutton-on-Trent that was ringed by SNRG, just over the river in Girton as an adult in September 2010. They retrapped it twice, once in June this year and again in August.

Barn Owls we have controlled include -

A bird in Muston in May this year, which was ringed as a chick in Lincolnshire in June 2011.

Another May bird in Muston which had travelled all the way from Suffolk where it was ringed as a chick in August 2013. Normal barn owl recoveries are local birds, but this one is from 136km away, quite a good distance for this species

A bird controlled in June in Girton, had originally been ringed as a chick in near Peterborough in June the previous year.

...and a bird originally ringed in Ruskington Fen Lincolnshire, in September 2013 as a chick, was controlled in Long Clawson in May this year.

Brackenhurst, Sunday 16 November

The forecast held good, being overcast, calm and damp through the morning. Apart from a round of 24 birds in the Orwin's nets, it was pretty quiet with little activity around the feeders. Personally, I think when its really calm birds are less inclined to move about in order to conserve energy. Still we managed to handle 47 birds, which just about kept our team of Kev, Linda, Sue, Gary, Alastair, Emma, Alex and me engaged.

The highlight would be a juvenile Magpie, the first for Brack since we started ringing there in 2008 and an unusual mist net capture. In between times we looked for a lost ram!

The sound lure only attracted two Redwing this time, but probably also accounted for the five 'continental' type Blackbirds. Later we tried a 'crest' lure and this maybe attracted the zephyr of 13 Long-tailed Tits, five of which were ringed last winter.

Captures were (new/retraps) 47 (28/19): Blackbird 5/0, Blue Tit 3/2, Chaffinch 1/1, Dunnock 1/0, Goldcrest 0/1, Great Tit 1/9, Long-tailed Tit 8/5, Magpie 1/0, Redwing 2/0, Tree Sparrow 4/1, Treecreeper 2/0.

Granby, Sunday 8 November

Another first winter visit; this time it was Granby. Our team was myself, Gary, Kev, Alex and Alister Feather from Birklands RG. The weather was calmer than forecast, but rain was expected late morning. In the event, the rain came early and we packed up around 09:30. Despite this we processed 50 birds. Surprisingly, what with the mild weather, we caught 23 birds before we'd got the nets fully open! Species were the usual suspects, but it was good for folks to get their eye in with the 18 Chaffinches we processed. All the retraps had been ringed last winter, bar a Dunnock from 2011. One of the Great Tits had been ringed by Ian in the summer as a pullus in one of the Granby nest boxes.

Captures were (new/retraps) 50 (40/10): Blue Tit 9/4, Chaffinch 17/1, Dunnock 3/1, Great Tit 6/4, Robin 3/0, Tree Sparrow 1/0, Wren 1/0.

Brackenhurst, Saturday 1 November

The forecast held and we managed our first visit to Brack this winter. Our team was Gary, Linda and myself. Though breezy, the nets were reasonably well sheltered, but what with that and the mild autumn, many leaves had to be extracted! The initial visit of the winter is always interesting in seeing the how breeding season has gone for the more common resident species. We set nets at the feeders and in Orwin's where we played a Redwing sound lure.

Overall, we processed 69 birds. About half were tits. As you might expect all the new Great Tits were birds of the year and retraps were from last winter. It looks like they've had a good year. Nine Tree Sparrows was a good total for here, and all appeared to be juvenile types and two of them were still in wing moult, but as we get no retraps one can't be definitive. Orwin's was productive with a charm of Goldfinches in one net and the lure pulling in eight Redwing.

Captures were (new/retraps) 69 (64/5): Blue Tit 10/0, Chaffinch 7/0, Dunnock 1/0, Goldcrest 2/0, Goldfinch 5/0, Great Tit 21/4, Long-tailed Tit 0/1, Redwing 8/0, Robin 1/0, Tree Sparrow 9/0, Wren 1/0.

Rushcliffe Community Awards 2014

On Wednesday 12 November, Jim and I, attended the Rushcliffe Community Awards 2014 on behalf of SNRG. We had been nominated again for an award in the Protecting and Enhancing our Environment category by Gordon Dyne.

Unfortunately we did not win, the top award was presented to Gotham Nature Reserve Trust, but we did receive a certificate again in recognition of our work.

Thanks go to Gordon for nominating the group.
