Linacre Nestboxes -2024 Season

 Last Thursday, Jayne and I popped down to Linacre to ring the last chicks (pulli) of the 2024 season. As it turns out, contrary to many areas, the nestboxes have been very good this year, with a total of 192 pulli, 1 adult Mandarin and 1 adult Pied Flycatcher ringed.

By far the most numerous bird ringed this year was, as always, Blue Tit. In total, I ringed 20 broods, ranging from 3 - 10 birds, making a total of 132 birds (the highest number since 2018). All these nests have now fledged, and only 6 birds didn't fledge - a fledging rate of 95%, which is pretty good. The second most numerous species was Great Tit, with 6 broods of between 5-8 birds, totalling 43 birds. This time all birds fledged, so 100% success rate! The third tit species, was Coal Tit, with just 1 brood of 6 ringed. Again, all the brood fledged, so another 100% success rate! This was particularly nice, as this is only the third time this species has used the boxes, since they were put up in 2006! Last year's clutch were predated, so the previous successful nest was back in 2011. 1 Tawny Owl was also ringed. This box hasn't yet been checked, so I don't know if it has fledged yet. Likewise, the adult Mandarin Duck, and her clutch still need to be checked. The last species, Pied Flycatcher, has also had its most successful year to date. In total, 3 nests were discovered this year, 2 of which had chicks that could be ringed (2 broods of 5). The first young ringed have now fledged, and the second box will be checked again next week. The other brood was predated.

As always, all nests were monitored for the BTO's Nest Record Scheme, and all birds ringed, were done so, under BTO licence.

Linacre Ringing - 2nd September 2023

 Yesterday morning I was down at Linacre, from 05.45 - 10.00, for a ringing session, with 2 other members of  Sorby Breck Ringing Group. It was our first session there since February, and we were treated to a great session, with 26 birds, of 6 species, including our first ever adult Tawny Owl and 2 of this year's pulli, that had been ringed in the boxes in May and June.

Tawny Owl

Birds ringed were (new/retrap): Tawny Owl 1/0, Blackcap 3/0 (all juveniles), Chiffchaff 1/0 ( 1 juvenile), Robin 1/0,  Blue Tit 10/1, Great Tit 5/3, Coal Tit 1/0.

All the retraps had originally been ringed at Linacre. 2 as juveniles in October and November 2022. The other 2, one Blue Tit and one Great Tit, had been ringed in the boxes in May and June this year.

Linacre Nestboxes Update

 On Monday I had a few hours down at Linacre ringing the first Blue and Great Tit chicks of 2023. In total, I ringed 11 broods; 6 Blue Tits (12, 5, 7, 6, 9, 7 and 11) and 3 Great Tits (4, 6, 5 and 11). I also had an hour there today, when I ringed another 5 broods; 3 Great Tits (6, 7 and 7) and 2 Blue Tits (6 and 6). 

There are still a few more boxes to ring, including a brood of 5 Pied Flycatchers.

Walking around, I also spotted this beautiful male Mandarin Duck and a brood of 13 Mallard ducklings.

Linacre Ringing - 5th November 2022

 Just two of us managed to get to Linacre for this week's ringing session with Sorby Breck Ringing Group, but we had a fantastic few hours with 46 birds, of 8 species, ringed.

As always, the majority of the birds were Blue and Great Tits, with 18 (15 new and 3 re-traps) of the former and 9 (8 new birds and 1 re-trap) of the latter caught. 2 Coal Tits (both new) were also caught, along with 11 Long-tailed Tits (all new), 1 Blackbird (new), 1 Chaffinch (new), 3 Goldcrests (2 new and 1 re-trap) and, best of all, a young Sparrowhawk - the first to be ringed at Linacre!!

Sparrowhawk!!

As well as the ringing, we also managed to see a flock of c.30 Redwings, c.20 Fieldfares and we also heard Tawny Owls calling.

Linacre Update - 22nd May 2021

 May is a busy month for  ringing, especially the nestboxes, at Linacre, so a visit on Saturday with 2 other members of  Sorby Breck Ringing Group saw a total of 50 pulli (young birds) ringed. All birds were Blue or Great Tits. Unfortunately, the Coal Tit nest I found in one of the boxes had been predated. Better news was the Pied Flycatcher nest. When checked, the female bird was sitting tight, hopefully on a nice, full clutch of eggs.

After checking the main nest boxes, I went down to 23 new boxes that have been put up by the bottom reservoir - The Glade. 3 broods of Blue and Great Tits were ringed. Whilst checking the boxes, a female Leucozona lucorum hoverfly landed on my arm. This was the first record of this species at Linacre!!

Linacre Ringing - 11th October 2020

 Last Sunday, 4 members of Sorby Breck Ringing Group were down at Linacre for a ringing session. It was quite quiet, with just 19 birds of  8 species ringed, but 2 Lesser Redpolls were very nice.

Bird numbers were (new/retrap): Blue Tit 3/0, Robin 1/0, Dunnock 4/0, Goldcrest 2/1, Blackbird 2/0, Treecreeper 2/0, Chaffinch 2/0 and Lesser Redpoll 2/0. 

The retrap Goldcrest, was one that we had ringed in September 2020.

Linacre Ringing - 12th September 2020

 Ringing at Linacre this year has been, as you can understand, pretty much non existent. Thankfully, however, we were able to a small team together on 12th September to have our second mist net ringing session of 2020. It was a quiet return, but we did manage to catch and ring 23 birds, including our first, and most likely last, summer migrant of the year, along with a Great Tit that we had originally ringed here in 2018.

As we'd expected, we'd missed most of the warblers this year, but, we did manage to catch one Chiffchaff (a juvenile bird). The other species caught were (new/retrap): Blue Tit 11/0, Great Tit 4/1, Coal Tit 1/0, Goldcrest 2/0, Dunnock 1/0 and Robin 2/0.

Other birds seen whilst on site were: Raven (1 over), Swallow (5), House Martin (13), Chiffchaff (3 feeding on buddleia, including 1 singing) and Tawny Owl (heard).

It was quite sunny whilst we were there and we also recorded several insect species: Red Admiral (1), Small Tortoiseshell (2), Small White (1), Speckled Wood (1), Meadow Brown (1) and Brown Hawker (1).

Linacre Nestboxes - This Year's Totals

With the easing of the lockdown restrictions, I've been able to get down to Linacre to monitor the nestboxes again this year for the BTO's Nest Record Scheme.  As it turns out, it's been a pretty good season, with a total of 156 pulli of 4 species ringed.

As always, the two most numerous species using the boxes were Blue and Great Tit, with 109 and 35 pulli ringed. One pair of Nuthatches used a box and raised 4 young, whilst Pied Flycatchers had 2 broods, one of which fledged 8 young. Unfortunately, the second brood of Flycatchers were predated. One other species also built a nest in the boxes this year, a Wren. The pair laid eggs, but they didn't hatch.

Linacre Nestboxes, Birds and Insects

I was able to get down to Linacre on Saturday to check the nestboxes for the first time this season. I walked around all three reservoirs and checked 87 boxes. In total, I found 37 boxes with active nests in them; 33 were either Blue or Great Tits, but there were also 2 Pied Flycatcher nests, 1 Wren nest and 1 Nuthatch nest. There were also 3 singing Pied Flycatchers, which is the highest count I've had, since the first ones were recorded in 2008. All nests are being monitored for the BTO's Nest Record Scheme.

Whilst on site, I also had a look for any insects that were active. I didn't see any butterflies, but I did spot this adult Cinnabar Moth that was emerging on a fence and a Scorpion Fly.

Cinnabar Moth

I also managed to see the first ducklings of the year. There were two broods of Mandarin Duck, 7 and 4, and one brood of Mallard with 3 ducklings.

The best sighting, however, was my first ever sighting of a Grass Snake. I spotted one basking on a stone wall by the bottom reservoir. Unfortunately, I only managed a quick photo before it slid off, into the wall. I did, however, manage to spot a "sloughed" skin in the same spot.

Spot the snake!!

Blue Tit Recovery

Obviously, because of the ongoing Coronavirus lockdown, I haven't been able to go to Linacre ringing since the start of the year. I was very pleased, therefore, to receive an email from David at Sorby Breck Ringing Group, with details of a Blue Tit that we'd ringed at Linacre on 16th July 2016 (see here).

The bird was aged as a 3J i.e. it was born in 2016, and was found dead (taken by a cat) on 28th April 2020, 1382 days after ringing, a whopping 8km away in Wingerworth, Chesterfield. This is quite a decent age for a Blue Tit , and also a pretty good movement.

Garden Ringing - 15th June 2019

I haven't done any ringing in my garden since March, so this morning I decided to get the net out for a few hours (05:45 - 09.00). My main target was to try and catch some of the 20ish juvenile Starlings that have been feeding daily in the garden, along with several ringed adult birds. By the end of the session I'd caught 17 birds, including 8 Starlings (6 new birds and 2 ringed birds), 2 juvenile Dunnocks, 4 Greenfinches (2 adults and 2 juveniles), 1 adult Blackbird and 2 adult House Sparrows.

I was able to sex the juvenile Starlings using their eye colour. The male birds have an all dark eye, whereas the females have a pale ring around the eye.

Female Starling

The two ringed Starlings that I managed to catch were very interesting. The first bird was an adult female with a very well developed brood patch (indicating breeding), and, when I read the ring, turned out to be a bird I'd caught in the garden in 20th May 2018. It had a brood patch then too.

The second ringed bird was a juvenile, and turned out to be one of the four pulli I'd ringed in May in the nestbox on the side of my house (see here). This bird was the only one of the 6 juveniles caught this morning to have started its post juvenile moult, as seen in this picture below.

It could also be sexed as a female, using the eye colour.

Other birds seen. but not ringed, were Chaffinch (2;1 male and 1 female), Goldfinch (4; 2 adults and 2 juveniles), Blue Tit (1 adult) and Coal Tit (1  juvenile).

Linacre Nestboxes - 4th May 2019

Luke and I had 2 hours at Linacre checking the nestboxes for the BTO Nest Record Scheme yesterday. Things had moved on very nicely since last week with 26 active nests (up from 25 last week), including 5 with chicks, one of which (8 Great Tit chicks), I was able to ring for the BTO Ringing Scheme.

Chicks!

The new nest was a very nice find, as it contained a bright blue egg in a grass cup, indicating a Pied Flycatcher nest. There were 3 singing Pied Flycatchers present as well, so hopefully, we'll end up with a few more nests as well.

Whilst walking around we also spotted 3 broods of Mallards (8, 9 and 1), 1 brood of Moorhens (3), 20 House Martins, 10 Swallows, and..... a Common Sandpiper (the first Linacre record of 2019).

I popped back down to  Linacre again this morning for an hour, and managed to find a singing Reed Bunting (first ever record of a singing bird, and my first Linacre record since 2013, when 1 was trapped and ringed (see here), and a singing Whitethroat. I managed to get an awful record shot of the latter bird, showing a ring. We haven't ringed that many Whitethroats at Linacre, so it would be great to retrap it this year to see if it is a returning bird or not.

Linacre Nestboxes - Update 28th April 2019

It's now been 2 weeks since my last check of the nestboxes at Linacre, so I went down this morning with 2 other members of Sorby Breck Ringing Group (thanks Sarah and Robin), to see how things had progressed. We found a total of 25 active nests (24 with eggs, and 1 with the first chicks of 2019; 8 Great Tits). Unfortunately, they weren't quite big enough to ring. The other nests were a mixture of Blue and Great Tits and contained between 5 and an impressive 14 eggs. A minimum of 2, possibly 3 Pied Flycatchers were also present and singing. The Mallard nest I found on a wall at the start of the month had, unfortunately, but not surprisingly, been predated. A Nuthatch was seen taking food into a natural cavity, possibly feeding a sitting bird? The results of today's visit will be entered into the BTO's Nest Record Scheme.

Whilst on site, we also recorded a couple of Canada Geese (still quite uncommon for Linacre), a pair of Raven flying over, Siskin (heard in the conifer woodlands by the top reservoir), 2 Buzzards and a new micro moth species Adela reaumurella.

Coal Aston Nests - 13th April 2019

I was out ringing this morning with 3 other members of Sorby Breck Ring Group at a local farm in Coal Aston. We had a steady morning, with 12 birds of 6 species, including our first ever Chiffchaff record from this site. Birds ringed were (new/retrap): Nuthatch 0/2, Dunnock 1/2, Blue Tit 1/1, Great Tit 3/0, Robin 1/0 and Chiffchaff 1/0. All the retraps were birds that we had ringed at this site previously.

Whilst there, we had our first check of the nestboxes for 2019, and were very pleasantly surprised to find 6 out of the 7 boxes were occupied (up from 2 last year). 1 box contained a Nuthatch nest, whilst the other 5 nests were all tit nests (1 with a 1/2 built nest, 1 with 5 eggs, 1 with 10 eggs, 1 with 8 eggs and 1 with 2 eggs). All eggs were cold, so incubation hasn't yet started.

Details of all the nests recorded, will be sent to the BTO's Nest Record Scheme.

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).

Coal Aston Ringing - 20th January 2019

I was out with 2 other members of Sorby Breck Ringing Group this morning for our first ringing session of the year at our farm site in Coal Aston. The owners of the site had reported that the feeders had been very busy since our last visit, so hopes were high for a good number of birds.

We weren't disappointed with a very respectable 33 birds caught (new/retraps): Blue Tit 15/4, Coal Tit 1/0, Great Tit 9/0, Robin 2/0, Wren 1/0 and Great-spotted Woodpecker 1/0. 

All the retrapped Blue Tits had been ringed at the same site; 2 on 30/09/17 (1 year 4 months ago), and 2 on 07/10/18 ( 3 months ago). They were ringed as 3s, so we know, more or less, how old they are. It'll be interesting to see how long they survive, and whether they breed on site this year.

Linacre Ringing - an update

I've been out ringing with Sorby Breck Ringing Group a couple of times recently. Both sessions were quite quiet with the following birds ringed:

18th November 2018 13 birds: Wren 1/0, Robin 1/0, Long-tailed Tit 3/1, Coal Tit 1/0, Blue Tit 1/1, Great Tit 4/0.

16th December 2018 25 birds: Dunnock 1/0, Robin 0/1, Blue Tit 1/8, Great Tit 8/5, Jay 1/0.

The highlight was, obviously, today's Jay, a first year bird, and the first ringed at Linacre this year.

Long Distance Blue Tit

This year I ringed 69 Blue Tit pulli (birds still in the nest) at Linacre Reservoirs and another private site in Coal Aston. In an average  year I'd expect to get a few retraps, usually within a few kilometres of the nestboxes the birds were ringed in. Imagine, then, my joy when I received an email from our data manager, with details about one of this year's birds that had been caught 19km away from its nestbox in Coal Aston.

The bird in question was the last bird ringed from a brood of 10 on 26th May. As you can see in the picture below, the nest is made up of approximately 90% horse hair, and was very warm indeed!

Blue Tits

The bird was re caught by another ringer of our group (Sorby Breck Ringing Group) on 17th November (175 days after ringing) on Bradfield Moor, which is 19km NW of the ringing site. Great record.

Linacre Ringing - 11th November 2018

Yesterday morning we (Sorby Breck Ringing Group) were down at Linacre to carry out a ringing session. Unfortunately, just one hour after we arrived, if started to rain, and we had to pack up. As a result we ringed just 11 birds, as follows (new/retrap): Robin 1/0, Goldcrest 2/0, Blue Tit 1/0, Great Tit 4/1 and Chaffinch 1/0.

Linacre Ringing - 20th October 2018

This month's ringing session at Linacre started at 6:45am, just before it got light, so that we could set the nets up and ready to try and catch the first Redwings of the autumn/winter period. We were lucky and managed to catch 2 new birds (both adults).

Redwing

We also managed to catch a Brambling (the first to be ringed at Linacre). The bird was a very smart male bird, born this year.

Brambling

The other, slightly different bird was a Coal Tit that was noticeable greyer than our usual birds. We identified this a "continental type" bird, i.e. most likely from mainland Europe! Here's a picture showing the "continental type" (right hand bird) along side a regular bird.

Coal Tits

Finally, we also caught and ringed 2 Greenfinch, another new species for Linacre.

Birds ringed (new/retrap): Wren 3/0, Dunnock 1/0, Redwing 2/0, Goldcrest 4/0, Coal Tit 7/0, Blue Tit 14/6, Great Tit 12/0, Nuthatch 1/0, Chaffinch 1/0, Brambling 1/0, Greenfinch 2/0 and Goldfinch 1/0.

Whilst on site we also noted 3 flocks of Fieldfare (10, 20 and 20) flying over, a lovely skein of approximately 100 Pink-footed Geese flying east and some very vocal (possibly 4) Tawny Owls.
