Seven Hours at Linacre!

 Yesterday (19th), I had a couple of visits to Linacre. The first, from 06.00 - 09.30, was a ringing session, with 3 other members of Sorby Breck Ringing Group, whilst the second from 14.00 - 17.30, was a solo walk, looking for insects and carrying out this month's WeBS walk.

The ringing session was quite a quiet affair, with just 9 birds ringed. Happily, 8 of the 9 birds were juveniles, i.e. born this year, but the low number was quite disappointing, given the time of year. Hopefully, numbers will pick up, as the summer progresses. Bird caught were (new/retrap): Blackcap 1/0 (juvenile), Chiffchaff 4/0 (all juveniles), Robin 1/0 (juvenile), Blue Tit 1/0 (juvenile) and Bullfinch 2/0 (1 adult - born last year, and 1 juvenile).

By the afternoon, the temperature had risen to 22 degrees, so I went back down for a walk around the site. As you can see from the picture below, the bottom reservoir is currently nearly dry. It has been drained as maintenance work is being carried out on the overflow. As a result there were few birds there, but the exposed mud could bring in some waders perhaps.

Waterbirds see were: Mallard (42 - 40 adults and 2 juveniles), Tufted Duck (24 - all adults), Mandarin Duck (17 - all adults), Coot (1 adult), Moorhen (3 adults), Grey Heron (1), Great-crested Grebe (3 adults - no juveniles this year), Herring Gull (1 adult), Lesser Black-backed Gull (5 adults and 1 juvenile),and, the best of all, a juvenile Common Sandpiper!

Whilst on site, I also spent a lot of time (!) looking at the amazing number of butterflies and other insects present. Very conservative estimates of species seen are: Meadow Brown (50+), Gatekeeper (9), Speckled Wood (3), Comma (2), Painted Lady (6 - 5 very fresh looking individuals and 1 very tatty one!), Holly Blue (4), Green-veined White (2), Large White (1), Peacock (3), Small Skipper (1), Silver Y (1), Shaded Broad-bar (1 in the ringing site), Brown Hawker (2), Common Blue Damselfly (100+, including ovipositing pairs), Blue-tailed Damselfly (1 male), Migrant Hawker (6), Volucella inanis (2), Volucella pullecens (3), Myathropa florea (1) and Eristalis sp!

Year List Update

 As January comes to an end, I felt it was time to update the Year List. There have been 5 new species since my last post.

The first addition was Brambling (83), that Jayne and I saw last weekend, at the National Trust Longshaw Estate. In total, there were 200+ birds in a mixed finch flock, including Brambling, Goldfinch and Chaffinch.

Brambling

The next 3 species were all seen this morning, during a ringing session in Shirebrook, Sheffield. Birds seen were: Goldcrest (84), Skylark (85 - flying over) and Bullfinch (86 - 1 male heard and seen).

The final bird was Red-crested Pochard (87). I saw this bird this afternoon, on Wingerworth Lido, Chesterfield, and it was most likely the same bird I had on a nearby pond last year. It was hanging around with the Mallards, and appeared to be interested in one of the female birds. Other species seen here were: Tufted Duck, Goosander (4; 2 males and 2 females), Mute Swan ( 2 birds), Moorhen, Coot and Black-headed Gulls (c.30).

Red-crested Pochard

Spurn Point - 25th October 2025

 On Saturday, Jayne and I went over to Spurn Point NNR to visit our nephew, who is volunteering there. Whilst there, we had an eight and a half mile walk from the Bird Observatory to The Point, and back, and managed to add 4 new species to the Year List.

The first new species was Whimbrel (200), that we saw feeding around the estuary and beach area.

Whimbrel

The next two species: Snow Bunting (201) and Black Redstart (202) were added on the walk down to The Point.

Black Redstart 

The final new species was a single Yellow-browed Warbler (203) that was feeding in willows around Sykes Field.

Other species seen were: Knot, Redshank, Dunlin, Curlew, Oystercatcher, Brent Goose, Whooper Swan, Chiffchaff,  Meadow Pipit, Stonechat, Skylark, Swallow, Buzzard and a female Bullfinch, that we tried, unsuccessfully, to turn into a "Northern" Bullfinch!

Pennington Flash - 12th January 2025

 Jayne had an appointment in Stockport on Sunday, so, after dropping her off, I drove across to Pennington Flash. The main lake was 95% frozen over, with 100s of birds close to the car park. With so much ice, I was able to find darvic-ringed Mute Swans, Coot, Black-headed and a Lesser Black-backed Gull, as well as 4 " Year Ticks".

The first ringed birds I saw, were all Black-headed Gulls. In total, I saw 9 different birds; 7 British-ringed birds (2T90, 2S94, 213A, 234B, 268C, 269C and 284C), and 2 Norwegian-ringed birds (J2714, ringed near Oslo, as an adult, in May 2024 and J3260, ringed, as a pullus, near Oslo, in June 2023).

J3260

The British birds had all been ringed at Pennington, between 2019 and 2022. None had been sighted abroad, except 213A, which was seen in The Netherlands in April 2024 (a possible breeding site?).

The Lesser Black-backed Gull, A70:W, was also seen on the ice. A record have been sent off, and I'll update, when I get the ringing details back.

Lesser Black-backed Gull A70:W

The 9 Mute Swans were all out on the side of the lake, enjoying the food being given out. The ringed birds were: CPT2 (green/W48751, 40ST (blue)/XY46_ _ _, 4FAU (blue), BY6 (blue)/ZY6998, 4BYN (blue)/XY2448, XY5830 (no darvic), XY4465 (no darvic), 4HFI (blue, age 5)/W43982 and 4HDN (blue, age 5).

The final bird, a Coot, with darvic ring J7F, was also out, feeding on the side of the lake. This bird was ringed, as an adult, at Pennington, in December 2020. My sighting was just the 4th since ringing.

Coot

All the Black-headed Gulls and the Coot had been ringed by the Waterbird Colour Marking Group.

After recording all the ringed birds, I had a walk around the reserve. It was very cold, and all the water was frozen. Despite this, I managed to find the following year ticks: Great White Egret (108), Bullfinch (109), Willow Tit (110) and Coal Tit (111).

Great White (and Little) Egret

Linacre Visit and Ringing - February 2024

 On 4th February, I had a walk around all three reservoirs at Linacre. It was 9 degrees, grey and overcast.

Birds seen/heard were: Song Thrush (4 singing), Raven (1 over, and 4, the highest ever count, were reported on 13/2), Bullfinch (1 female), Grey Wagtail (2, including 1 singing), Great-crested Grebe (1), Little Grebe (2), Goosander (6; 4 females and 2 males), Mallard (102), Tufted Duck (24), Mandarin Duck (7), Moorhen (12), Coot (9) and Black-headed Gull (18).

Last weekend (10th), I was back at Linacre, with Sorby Breck Ringing Group, where we ringed 33 birds of  species. Birds ringed were (new/retrap): Blue Tit 7/4, Great Tit 1/3, Coal Tit 1/1, Long-tailed Tit 8/2, Goldcrest 2/0, Robin 2/1 and Treecreeper 1/0.

Most of the retraps were from last year, but we did retrap a Robin first ringed in April 2021 (born in 2020), and two Long-tailed Tits that had been ringed, on site, in October 2022. 

Whilst on site I recorded a few new birds for the Year List. The first was a Woodcock (116) that was flushed from the ringing site, followed by Great-spotted Woodpecker (117) and Goldcrest (118).

Hassop Waxwings

 After my walk around Linacre yesterday, Jayne and I drove cross to Hassop Station near Bakewell to see the 250+ Waxwings (42) that had been present for the last couple of weeks. They were "showing very well" in the trees around the café area, and we got fantastic views.

One of the photos was of a bird with a colour ring on. Details have been sent off, and I'll update the blog as soon as I hear back.

Waxwing

Other birds seen were: Redwing, Bullfinch (43), Rook (44), Magpie (45), Canada Goose (46), Pied Wagtail (47) and Sparrowhawk (48).

Dutch-ringed Redwing at Linacre

 Every year, we try to catch some of the Redwings, that spend the winter months in Britain. This morning, we (Sorby Breck Ringing Group), were at Linacre before light to set up the nets and see if we could get lucky. By the end of the morning, we had ringed 8 birds (of about 30 in the area), including our first ever foreign-ringed bird, a juvenile ringed in Holland. Further details of exactly where and when, to follow when I hear back. UPDATE: the Redwing had been ringed 510km away, in The Netherlands, 8 days before it was caught at Linacre. Fantastic!! 

Dutch-ringed Redwing

Birds ringed were (new/retraps) : Redwing 7/1, Blackbird 1/0, Great Tit 8/0, Blue Tit 7/1, Coal Tit 2/1, Long-tailed Tit 2/0, Treecreeper 1/0, Wren 1/0, Chaffinch 1/0, Bullfinch 1/0 and Goldcrest 5/0.

Whilst there we also spotted a few other birds: Cormorant (1 over), Raven (1 heard), Tawny Owl (heard first thing), Jay ( 2 seen), Skylark (1 heard), Buzzard (1 over) and Sparrowhawk (2; a male and female hunting the Redwing!!).

Linacre Ringing - 24th November 2019

Yesterday I was down at Linacre for a 4 hour ringing session with 3 other members of Sorby Breck Ringing Group. We had a steady morning, with 41 birds of 11 species.

Numbers were as follows (new/retrap): Blue Tit 6/7, Great Tit 7/5, Long-tailed Tit 1/2, Coal Tit 3/1, Redwing 1/0, Blackbird 1/0, Wren 1/1, Bullfinch 2/0, Chaffinch 1/0 and Jay 1/0.

Lesser Whitethroat "blythi" - 3rd February 2019

Back in February (3rd), I had my first garden ringing session on 2019. I had the 20ft net up by the feeding station and caught just 8 birds including 2 Blackbirds, 2 Goldfinches, 1 Bullfinch and 2 Long-tailed Tits (first for the garden).

The highlight of the morning, however, was the very last bird, which turned out to be a LESSER WHITETHROAT!! I've only ringed 1 previously, so I was very excited to see this species in the net, but, given the time of year, I was even more surprised to see it, and my first thoughts were.... is this an "eastern" type bird?

Lesser Whitethroat "blythi"

The first thing I noticed once in the hand was the small size, and the 2 prominent outer tail feathers. The tail feathers, in particular, looked interesting, so I quickly "processed" the bird (put a ring on, aged it as a 5, based on 1 retained greater covert, and a tail with 2 generations of feathers, and measured the wing, 63mm), before phoning a more experienced ringer to get some advice. Numerous photos were also taken showing the wing, tail and body.

Lesser Whitethroat tail

I was advised to retain any feathers lost during ringing, for DNA analysis. These feathers were subsequently sent to Aberdeen University, where said DNA analysis was carried out, confirming the bird as an "eastern" Lesser Whitethroat, subspecies blythi!!!!!!!!!

This is the first confirmed record of this subspecies in Derbyshire. There have been 2 previous "possibles" 1 in 1998 (a bird seen at feeders in November and December), and a bird seen in a garden in Eggington from December 2013 to March 2014.

Linacre Ringing - 26th January 2018

Saturday saw 6 members of Sorby Breck Ringing Group back down at Linacre for the second ringing session of the year. We had a relatively quiet session with just 18 birds ringed, as follows (new/retrap): Coal Tit 0/1, Blue Tit 7/7 and Great Tit 3/0.

Whilst on site we also had the first records of 2019 for Song Thrush (1 bird singing) and Common Buzzard (1 over). Also seen were, Sparrowhawk (2 birds together over the ringing site),  Bullfinch, Siskin and Mistle Thrush (2 seen, and heard singing).

Linacre Ringing - 22nd September 2018

This morning I was down at Linacre with 4 other members of Sorby Breck Ringing Group. We had 4 hours on site and caught 38 birds (new/retrap): Robin 2/0, Chiffchaff 7/0, Goldcrest 2/0, Long-tailed Tit 8/0, Blue Tit 11/1, Great Tit 6/0 and Treecreeper 1/0.

Treecreeper

Whilst there, we set a net for Meadow Pipits, and, although they came down, none found their way into the nets.

Also seen during the ringing session were: House Martin (c.30 overhead), Green Woodpecker (1 heard), Kestrel (1), Sparrowhawk (1), Bullfinch (1) and Great-spotted Woodpecker (1).

Linacre Ringing - 7th July 2018

Back at the start of the month I was down at Linacre with Sorby Breck Ringing Group for the first mist netting session since April. We had an early start, arriving on site at 4.45am, and caught a very respectable 74 birds of 13 species.

Birds ringed (new/retrap):  Dunnock 1/0, Robin 7/0, Blackbird 1/0, Blackcap 9/0, Chiffchaff 2/0, Goldcrest 1/0, Long-tailed Tit 2/0, Blue Tit 24/4, Great Tit 13/3, Nuthatch 1/0, Chaffinch 1/1, Goldfinch 3/0 and Bullfinch 1/0.

The best thing about the birds caught was that the majority were young birds, possibly indicating a good breeding season? We also had 3 of the re-trapped Blue Tits and one of the re-trapped Great Tits were young birds ringed by Sara from the Group in the nest boxes at Linacre a month earlier.

Three species, however, that were missing from the ringing totals were Willow Warbler, Garden Warbler and Whitethroat. All 3 species have been recorded singing in the area this year, so hopefully, we'll be able to confirm breeding next time we're down ringing.

Kestrel - new species at Linacre

I was down at Linacre this morning for the second ringing session of the year. We started off well with a great catch of 14 Long-tailed Tits ( 8 new and 6 retraps), but then things got quite quiet, until the last net round when we found a new species in the net - a Kestrel!! We often see a Kestrel flying and hunting around the site whilst we are ringing, so today's catch was a very nice surprise.

Kestrel

Other birds ringed today were (new/retrap): Robin 3/0, Blue Tit 6/3, Great Tit 1/3, Nuthatch 2/0, Chaffinch 1/0 and Bullfinch 1/0.

Other birds seen around the ringing site were: Sparrowhawk (1 female), Common Buzzard (1), Great-spotted Woodpecker (4), Green Woodpecker (1 seen and heard), Mistle Thrush (4; 2 pairs, including 1 singing bird), Siskin (1 over), Cormorant (1 over) and Tawny Owl (1 heard calling at 6:45am).

Linacre Ringing - 25th November 2017

Last Saturday saw 5 members of the Sorby Breck Ringing Group down at Linacre for a ringing session. The weather was a bit blustery, with a few rain/sleet showers and a temperature of just 4 degrees, so, as you can guess, the ringing was slow. After 3 hours we'd caught just 9 birds of 5 species, namely (new/retrap): Blue Tit (3/1), Great Tit (1/0), Coal Tit (1/0), Goldcrest (2/0) and Dunnock (0/1).

Other birds recorded on the ringing site were: Redwing (20+ over), Fieldfare (12, the first of the winter), Long-tailed Tit, Bullfinch (heard), Chaffinch, Jay (2 seen), Magpie (1), Blackbird, Song Thrush (1 seen) and Kestrel ( 1 hunting over the site).

Whilst there, my nephew, Luke had a quick walk around the bottom and middle reservoirs were he recorded: c.20 Black-headed Gulls, 12 Mandarin Ducks, Mallard, 1 Great-crested Grebe and 2 Cormorants.

French-ringed Reed Warbler

Yesterday I was out for my first ringing session in a while at Poolsbrook Marsh, with 5 other members of Sorby Breck Ringing Group.

We arrived on site at 5.00am, got the nets out and started to catch some birds. By the end of the morning's session we had caught 73 birds of 15 species. Totals were (new/retrap): Wren 2/0, Dunnock 2/0, Robin 1/0, Blackbird 1/0, Sedge Warbler 1/0, Reed Warbler 33/2, Lesser Whitethroat 2/0, Whitethroat 3/0, Blackcap 6/0, Chiffchaff 2/0, Willow Warbler 5/1, Willow Tit 4/0, Blue Tit 0/1, Bullfinch 4/0 and Reed Bunting 3/0.

As you can see, we had a good range of resident and migrant species, including 7 species of warbler. The vast majority of birds were new (and juveniles), but we did have a few previously ringed birds, including a very special Reed Warbler bearing a "Museum Paris" ring!! As the name implies, this bird, which we aged as an adult, had been ringed in France. It'd be great to think that it is a bird that was born at Poolsbrook, and was then ringed on migration through France, before returning the breed here in Derbyshire. I'll update the blog when we get the details back from the BTO.

Other birds seen today included Kingfisher, Common Buzzard and Water Rail (heard only).

Linacre Ringing and a 2 new Species

I was out ringing with 3 members of the Sorby Breck Ringing Group at Linacre yesterday. We had 3 and a half hours on site, but only caught 9 birds, most of which were retrap Tits (Blue, Great and a single new Long-tailed). We also had singles of Dunnock and Bullfinch (a 5 male). Unfortunately, no warblers were caught, although Chiffchaff, Willow Warbler and Blackcap were all heard singing.

Whilst there, the sun came out for a while, and a Peacock butterfly was seen, along with a moth. I grabbed a quick photo, and was very pleased to identify it later as a Water Carpet - a new species for me and for Linacre (as far as I'm aware).

Water Carpet

Apparently, this species is quite common in Derbyshire, so is presumably quite common here, but has, so far, been overlooked. A nice addition.

The other "new" species was , I think, a Short-tailed or Field Vole. The individual was found underneath an old manhole cover that was on the grass by the ringing site. I lifted it up, and spotted this.

Field Vole

As you can (hopefully) see, its the back end of a Vole, and appears to have a very short tail. According to The Wildlife Trust's website (see here),  a Field Vole's tail is approximately 30% of its body length, so I quite happy that the id is correct. We did, also, see its face, but I didn't manage a photo of that end!! Now I know what the Kestrel that we saw, was after.

Avenue Ringing - 2nd April 2017

After a few weeks without a ringing session it was really nice to get out and about again today. I spent 3 and a half hours out with 4 other members of the Sorby Breck Ringing Group at the Derbyshire Wildlife Trust's Avenue Washlands in Chesterfield. We had a quiet session with just 17 birds ringed, but the total did include our first summer migrants of the year; 3 Chiffchaffs and a single, female Blackcap.

Chiffchaff

Blackcap

Today's totals were (new/retrap): Chiffchaff 3/0, Blackcap 1/0, Blackbird 1/0, Blue Tit 0/1 , Great Tit 0/2, Long-tailed Tit 0/1, Dunnock 1/1, Robin 1/2, Wren 0/1, Bullfinch 1/0 and Reed Bunting 1/0.

During net rounds we also recorded these birds: Sparrowhawk, Green Woodpecker (year tick), Linnets, Yellowhammers, Goldfinch, Canada Geese and Mute Swans.

Year List update:
117 - Green Woodpecker
118 - Raven (1 over Sudbury Hall, Derby, this afternoon)
119 - Shoveler (1 male on Sudbury Hall lake).

Siskins and a Redpoll

I haven't been out ringing for a couple of weeks, so this morning's session at our private site in Wingerworth, Chesterfield was a nice chance to get back out again. We met up at 6.30am and ringed 44 birds of 12 species over the next 4 hours. As the title suggests, the highlights were the Siskins and a single Lesser Redpoll. We don't ring lots of these species, so when they're around, it's nice to catch a few. We've also had some good recoveries of Redpolls ringed at this site when they return to Scotland to breed. Hopefully, some of today's birds will turn up there later in the year.

Siskin

Today's totals were (new/retrap): Siskin 4/0, Lesser Redpoll 1/0, Goldfinch 14/0, Chaffinch 4/0, Bullfinch 3/0, Robin 0/1, Blue Tit 3/4, Great Tit 2/1, Long-tailed Tit 1/1, Robin 0/1, Wren 1/0 and Goldcrest 1/0.

Other birds seen and heard this morning were: Song Thrush (singing), Blackbird, Collared Dove, Woodpigeon, Great-spotted Woodpecker and Stock Dove (year tick). There were also at least half a dozen Common Frogs spawning in the pond.

Year List update:
110 - Stock Dove

How old??

How long do birds live? is a question we are often asked by members of the public at ringing demonstrations. I was asked this exact question whilst out ringing yesterday with Sorby Breck Ringing Group at the Derbyshire Wildlife Trust's Avenue Washlands reserve. The bird in question was a Blue Tit that we'd just extracted from one of the nets and was found to be wearing a ring already.

David checked the ring number when he got home, and emailed the following details. The bird had originally been ringed at The Avenue on 28th March 2010 and aged as a 5M i.e. it had been born in 2009. It had only been re trapped once before today, on 27th February 2011, also at The Avenue. This means that this bird is now 7 years old (in its 8th calendar year), which is a pretty impressive age for such a small bird. A quick check of the BTO's Longevity Records , shows that the oldest Blue Tit on record was 10 years, 3 months and 10 days old when it was last recorded, so "our" bird still has a few years to go!

Other birds caught during yesterday's session were (new/retrap): Wren 0/1, Dunnock 2/1, Robin 3/0, Blackbird 5/0, Song Thrush 0/1, Long-tailed Tit 1/0, Blue Tit 0/4, Great Tit 3/1, Chaffinch 2/0, Goldfinch 1/0, Bullfinch 4/3, Yellowhammer 1/0, Reed Bunting 11/1.

Colour-ringed Waxwing

I was driving past Sheepbridge Business Centre in Chesterfield yesterday, when I spotted the familiar silhouette of a Waxwing perched up in trees. I pulled the car over and saw that there were in fact 30 birds in the trees, which, after a couple of minutes, flew down and started to feed on the few remaining Rowan berries. I grabbed  a few photos, but then spotted that one of the birds was colour- ringed!!

Waxwing (green over red)

Details were quickly emailed to the Grampian Ringing Group, who informed me that the bird had been ringed in Inverurie, Aberdeenshire on 27th November 2016 as a 3 male i.e. a bird born that year. My sighting was the first since ringing. Hopefully, it'll keep being reported again, either here in the UK, or possibly back as a breeding bird in northern Europe somewhere.

Other birds seen in the same tree were: Redwing (4), Blackbird (3), Bullfinch (1 female), Great Tit (1) and Mistle Thrush (1).
