A lengthy round up!

Firstly, a quick note to say sorry about the incorrect formatting on my last post - I don't know what Blogger did, but it certainly wasn't written in one big block!

It's been a while since I posted some photogrpahs and accounts of my ringing activities. I have been out ringing, in between scattering my Dad's ashes, dealing with his stuff, bad weather and taking well earned rests!

Scattering my Dad's ashes went as well as could be hoped for. Everything went smoothly, it didn't rain although the clouds did look threatening! My dad would have liked the moody skies, the location, how we did it and that we were joined by a pair of Ravens, a Sparrowhawk and with near perfect timing and as I'd hoped, just after the last scattering - a Red Kite. He would have liked that too.

I also did some ringing at my dad's house. There were few birds about but I did manage to catch 20+ House Sparrows (more than I've ringed there before in total) and a new species - Chiffchaff. Elsewhere, however, the best day started thus:


Sunrise at Sandy Smith Nature Reserve, above, on 20th August 2013. The sunrise was good as I drove into the site but as I walked round the corner carrying my equipment, I had one of those moments where you just have to stop and say 'wow' and drink in the beauty of the moment.

The day continued well with 78 birds in total (retraps in brackets):

Great Spotted Woodpecker 0 (1)
Dunnock 4 (1)
Robin 3 (1)
Whitethroat 3 (0)
Blackcap 3 (0)
Chiffchaff 4 (1)
Willow Warbler 6 (0)
Coal Tit 1 (0)
Blue Tit 5 (13)
Great Tit 3 (20)
Chaffinch 3 (1)
Goldfinch 4 (0)

and best of all...


Above: Spotted Flycather (2nd ringing record for the site, previous being in 2011). A juvenile, presumably on migration or a local roaming around.

A session previous to this, on 10th August, again at Sandy Smith NR, exactly 100 birds were caught of 14 species:

Wren 4 (1)
Dunnock 3 (2)
Robin 1 (1)
Reed Warbler 1 (0) - 2nd this year and only the third ringed for the site
Whitethroat 8 (1)
Blackcap 3 (1)
Chiffchaff 9 (0)
Willow Warbler 2 (0)
Long Tailed Tit 3 (1)
Marsh Tit 1 (0) - only 3rd ringed for the site
Blue Tit 8 (8)
Great Tit 7 (29)
Treecreeper 1 (0)
Chaffinch 4 (1) - there are a LOT of juv chaffinches this year!


Above: Marsh Tit

It's been an interesting year so far at SSNR. New for year totals of Great Spotted Woodpecker, Chiffchaff, Willow Warbler, Goldcrest, Long Tailed Tit, Coal Tit, Great Tit, Treecreeper and Chaffinch are all higher than in previous years (operating since 2010) whilst Redwing and Jay have been added to the ringing list this year.

Last year, I set myself a goal of reaching 1000 captures at SSNR for the year (and just made it). This year, I have been keeping tabs on my progress and (adding yesterdays total of 41) I have reached 870 captures (of 30 species), putting me ahead of schedule in comparison to the previous two years.

Breaking this down into effort, I reckon I've had 1 or 2 more nets up and they've been up for longer rather than making more visits. I've also got wiser about the catching some species, but then some species are more abundant this year and some are less so. So, a bit of swings and roundabouts then!

Before reaching 1000 for this year though, I think the next milestone will be the 2000th new bird ringed as 39 more new birds are needed for this.

A quick mention for Priory Country Park - with the help of other members of the Ivel Ringing Group & visitors, we completed all 12 visits of the Constant Effort Survey. I haven't studied the results in any depth but I can tell you that overall, this is one of the worst recorded years since it started in 1992. I will put something up soon about this on the Ivel Ringing Group Blog.

Lastly, I can now share a photograph with you from a ringing session on 7th July, 2013. 


Above: A Juvenile Jackdaw

This is the second Jackdaw (both juveniles) ringed at SSNR following one last year (when I didn't have my camera with me). This was caught on the day my dad passed away. A day which, apart from the obvious, was a perfectly nice and enjoyable day.

Latest news

I'll start with the best bit of news:

The original ringing details for the Siskin I caught in December last year (see here for original blog post) with a Bruxelles ring on it have come through.

It was ringed in Wibrin, Luxembourg, Belgium on 24th February 2012 as an adult female (Euring code 6) and was recaptured by me 288 days later (on 08/08/12) at Sandy Smith Nature Reserve. A movement of 474km in a WNW direction.

I'm pleased with that one.

I always like to attach a few photographs but because of more 'technical issues' I can't share them at the moment. So that has stopped me sharing my other ringing news with you. A quick review of the highlights are:

52 birds caught on CES visit 8 at Priory Country Park - an excellent total in a good year let alone in an average/poor year. 26 birds on CES visit 9 was more expected, but did include a juvenile Green Woodpecker.

At Sandy Smith Nature Reserve my last 4 or 5 catches have all been over 50 (with one of 86). Lots of juveniles have been caught including good numbers of Great Tit, Blue Tit and Chaffinch. Juvenile Willow Warblers have been caught as well as a couple of Chiffchaffs. Juvenile Blackcaps have been caught but not in good numbers. Whitethroats have also produced a few juveniles - more than last year, but still numbers are low. A juvenile Jackdaw was a highlight.

One remarkable achievement - including juveniles and adults, I have now ringed/recaptured 16 different Great Spotted Woodpeckers this year! The multiple recapture data is helping construct a good picture of what is happening locally with this species.

I'll restore the picture feed, hopefully, and will have further news soon. Ta ta for now.

Last weekend.

As a nice change of pace, Sunday and Monday (last weekend) were largely wind free! This allowed me to get out ringing and catch some of those summer migrants that come to breed in the UK and begin another year of Constant Effort ringing at Priory Country Park (PCP).

On Bank Holiday Monday, a visit to Sandy Smith Nature Reserve produced a tally of 40 birds of 12 species as follows (retraps in brackets).

Green Woodpecker 1 (0)
Great Spotted Woodpecker 1 (4)
Wren 2 (0)
Dunnock 1 (1)
Sedge Warbler 3 (1)
Whitethroat 2 (5)
Garden Warbler 1 (0)
Long Tailed Tit 0 (1)
Great Tit 1 (3)
Chaffinch 6 (3)
Greenfinch 2 (0)
Goldfinch 2 (0)


Above: A Garden Warbler. This is the 9th ringed here.


Above: A Whitethroat. 2 of the retraps were ringed here in 2011 whilst the other 3 were ringed last year (all as adults). L302789, ringed on 22/04/11 set a new longevity record for the site at 2 years and 14 days.

Whitethroats are the 3rd most ringed species at SSNR behind Blue & Great Tits and as long as this spring/summer proves to be a good breeding year, I expect to ring a lot more of these.



Above: A female Greenfinch. A surprise appearance of a male and female at the feeders represents the 8th and 9th ringed here (none have been retrapped).


Above: A Sedge Warbler. The retrap was ringed here July 2012.


Above: A female Green Woodpecker. Always a good day when I ring one of these! The 4th for the site.

Hardly a ringing session at SSNR goes by without a Great Spotted Woodpecker being retrapped and/or ringed. One male, CW08915, doesn't get retrapped during the winter months (Nov to February) but is regularly caught throughout the rest of year. At 2 years and 46 days since it was first ringed, this bird set a new longevity record for the site. I am still hoping to catch CW08911 (the female who I think breeds with CW08915) as this bird also disappears during the winter months.

Chaffinches were, surprisingly, the most numerous species. I normally catch a couple per session but I think a small change in feeder & net set up may have proved to be useful. A new longevity record for the site was set by L302734 - 2 years and 62 days. Also, a bird ringed in a field at nearby Beadlow earlier this year was retrapped at SSNR.

On Sunday, I ran CES Visit 1 at PCP. Totals, including extra nets, were as follows (retraps in brackets):

Wren 2 (1)
Dunnock 1 (3)
Blackbird 1 (2)
Whitethroat 3 (3)
Garden Warbler 1 (0)
Blackcap 3 (1)
Willow Warbler 2 (0)
Long Tailed Tit 0 (1)
Great Tit 1 (0)
Chaffinch 1 (0)
Bullfinch 1 (1)

That makes a total of 16 new and 12 retraps - 28 overall. Average for CES visit 1 (including extra nets) is 30, of which 21 are normally 'new' and 9 are normally 'retraps'. Whilst the 2013 total is just short of average, the ratio of new to retrap is more in favour of the returning adults rather than recruitment of new adults. This could be a result of a poor breeding season last year. Delayed breeding and migration from the cold weather in early spring may also have a bearing here. But this is just a small sample and I'm far from being an expert!

Whitethroats were the most numerous on this visit and could be seen feeding well around the area. One of the retraps was first ringed on 1st May 2011, whilst the other 2 retraps were both ringed on 13th May last year.

2 of the 3 Dunnock retraps were from 2010 and the other from last year. One of the Blackbirds was ringed in 2010. The Blackcap retrap was ringed as a juvenile in July 2011. All the other retraps were from birds ringed in 2012.

The best birds were 2 new Willow Warblers. The numbers ringed at this site have steadily decreased over the last 20 years to the point where last year was the first year where none were ringed at all.

This weekend may prove to be too windy and/or wet for ringing, so I might post a few bird photographs from Sardninia...

Priory Country Park - Of late

The Constant Effort season is over at Priory Country Park. All 12 visits were completed (including the odd extra visit). I haven't posted CES totals for a while and on this occasion, for my ease, I'm going to lump visits 8-12 all into one (including non-CES birds/sessions).

238 new birds, 57 retraps (in brackets) of 23 species:

Wren 8 (1)
Dunnock 6 (6)
Robin 6 (7)
Blackbird 10 (8)
Song Thrush 8 (1)
Sedge Warbler 1 (0)
Reed Warbler 24 (1)
Whitethroat 25 (6)
Lesser Whitethroat 2 (0)
Garden Warbler 19 (2)
Blackcap 91 (8)
Chiff Chaff 2 (3)
Willow Warbler 2 (1)
Blue Tit 8 (5)
Great Tit 6 (3)
Long Tailed Tit 0 (1)
Chaffinch 3 (0)
Goldfinch 10 (0)
Greenfinch 1 (0)
Bullfinch 4 (3)
Treecreeper 0 (1)
Sparrowhawk 1 (0)
Wood Pigeon 1 (0)

We'll start with the standout total for Blackcap. This site has always been good for Blackcaps - more Blackcaps have been ringed than just about all other species in the park. The total above includes birds caught outside the CES. On Saturday 27th August I caught 26 Blackcaps (the majority new and the majority male). These birds must have moved on and another lot moved in as by the following Wednesday (31st August) I caught 30 Blackcaps (only one retrap from the weekend and only because it's from a late brood & not ready to go yet).

I call on all ringers north of Bedfordshire to get a move on and ring some Blackcaps! Out of all the Blackcaps I've ringed here in the last week or two, none have been ringed other than on site. You can increase my chances of catching one of your birds!

Above: A Wood Pigeon (the big ball of feathers).



Above: A Lesser Whitethroat. This bird represents one of two ringed on 27th August. This species used to be more regular in the park but there have been very few records this year. I assume therefore that these two birds (juveniles) were migrating through the park (we would likely have caught the adults & juveniles earlier if they had bred).



Above: Normally seen in the skys above & normally too good at airobatics to be caught. This juvenile Sparrowhawk is obviously still learning then!

Green Wood Ringer strikes!

My first self caught Green Woodpecker!



The red in the malar stripe (below the eye) makes this a male.



Seeing a Green Woodpecker in the hand was one of my main motivations to become a bird ringer. I can't count the number of times I've seen one and willed it to go in the net!



As it flies away from you, laughing, the flash of green sticks in the memory.

The chance (however small) of someday having another one in the hand will keep me getting up at silly o'clock most weekends for a long, long time! And whilst I'm waiting for the next Green Woodpecker I might catch a few other birds that will put a big smile on my face too.

To see more info on the other birds I caught today (including only the second Coal Tit to be ringed at Priory Country Park) on CES visit 4, please click here.

Constant Effort visit 1 - Priory Country Park

Sunday 1st May was the start of the CES season - it was sunny all morning. Chilly first thing with the wind picking up intensity throughout the morning probably resulting in a reduced catch in the second half.

18 birds of 12 species: New (retrap)

Bullfinch 3 (0)
Cetti's Warbler 0 (1)
Dunnock 2 (0)
Wren 0 (1)
Whitethroat 1 (0)
Reed Warbler 1 (0)
Blackbird 0 (2)
Garden Warbler 1 (1)
Goldfinch 1 (0)
Blue Tit 0 (1)
Chiff Chaff 2 (0)
Blackcap 1 (0)

Interesting info on some of these birds:

1 female Blackbird was born in 2008.
1 male Blackbird was born 2007 (first caught in 2008)
1 returning male Garden Warbler was ringed as an adult in 2010
The female Bullfinch's have well developed brood patch's
A male Blackcap with a false brood patch.

My no.1 bird ...

I was surprised to find this in the net today. Usually they are somewhere about laughing and teasing me & flying nowhere near the net! In fact, earlier on, I had shouted out to one such Green Woodpecker and suggested it should get in the efin net!



Above: My first of this species but hopefully not the last!



Above & below: From the front & back. When they fly away from you, there is a flash of yellow (like the flash of blue you see in kingfishers).

No more false advertising!

No surprise that I am posting lots of photographs of this bird!



Above: The wing was in primary moult.

Above: Unlike the Great Spotted Woodpeckers, the Green Woodpecker does not take chunks out of your hand or try to draw blood!
