A thrilling wildlife moment - redstart

I had one of those truly thrilling wildlife moments yesterday - it's very personal and relates to redstarts, a relative of the robin which have just arrived in the UK from West Africa. They are stunning birds and at Portbury Wharf Nature Reserve I had the chance to hold and ring a beautiful male. Some people may opt for a bird of prey or a colourful parrot as their ultimate bird to see up close, but for me, seeing this beauty in the hand was just so exciting!

After missing out on a deluge of migrants dropping in to the reserve on Saturday morning I was determined to be at the ringing site on Sunday morning after leading a dawn chorus cycle ride in Bristol's Avon Gorge. There were less migrants around but from our ringing site we were watching a female and the odd male redstart fly-catching in the nearby scrub. 


Towards the end of the ringing session, around lunchtime, I went to check some nets for the last time and suddenly spotted a male redstart on the grass. It flew away from me and flew straight into the pocket of one of our mist nets! Eureka! I ran over to the net, safely removed the bird and brought it back for ringing. 


And here it is!

I've been wanting to see one up close for years - I used to spot redstarts at Thursley Common in Surrey when I was a teenager and have since seen them in the Forest of Dean and different parts of Wales. 
However, their black mask, white forehead and rusty-red tail have fascinated me - a truly flashy bird. 

What's even more remarkable is that these birds have been wintering in the scrubby woodland in parts of West Africa - countries such as Guinea, Ghana and Ivory Coast. In recent weeks they have been flying across Africa, into Spain, France and in recent days have arrived en masse in the UK. And they've been everywhere, heading to mature oak woodlands, heathland and pasture, particularly in the west of Britain. 


Let's hope he makes it to his woodland territory and gets spotted by another ringer or birder!

Young Peregrine travels from Avon Gorge to the West Midlands

I've been colour-ringing peregrine chicks since 2007 with the help of fellow BTO ringer Ade George, and volunteer climbers from the British Mountaineering Council. In each year I have been building up the number of nest sites we visit to maximise how many chicks we ring. With bird ringing (or banding) it is a numbers game - the more birds you ring, the more likely someone will spot one of 'your' birds and report it. With colour-ringed birds this likelihood increases hugely - while only perhaps 2% of birds with just metal ID rings may be resighted, up to 98% of birds colour-ringed may be recovered.

With my peregrine work the results can be a little delayed. In the first first few years a peregrine's life is very nomadic as it travels around getting to know the region and no doubt look for a mate. So it's not until a peregrine begins to settle at a nest site at two or three years old that it may be seen and identified by birders.


Of my peregrines that have been re-sighted so far, most have been quite close to Bath and Bristol, near where we ringed them. For example, one was seen with a female partner 15km south of Bristol from where it was ringed two years later; another is now the breeding male at a nest in Bath where it hatched; and a third individual was re-seen later in the autumn at the site where it was ringed and had fledged earlier that year.


Our furthest travelled bird however goes to the following individual. One of the young peregrines we ringed in the Avon Gorge in 2010 was also filmed for the BBC's Springwatch.
He was given a blue colour-ring with black letters, BT (his sibling BX is in the photo above)


He was spotted and photographed by Michael Colquhoun in the Malvern Hills, Worcestershire back in April 2011. This was exciting news and it was great to know one of the chicks had ventured so far.

However, I then had sad news in October 2011 that a peregrine with one of my colour-rings had been found dead by a dog walker not far from KIdderminster in the West Midlands. After exchanging e-mails with local birder Jason Kernohan who met the dog walker and recovered the dead bird, I discovered it was the same colour-ringed individual, BT. 


He had been dead for four days before being found (as indicated by the development of moaggots). He was taken to a vet by the police for an x-ray to confirm he hadn't been shot. He had been found below power lines and seems likely he had died from some interaction with these.

Despite this young bird's death I'm pleased we know his final outcome and where he travelled. It helps build up a bigger picture of what peregrines do when they fledge. It's interesting that we've not heard from the other four chicks that were in that same family. Yet we have heard from this individual twice! Hopefully as the other four (assuming they are all alive) begin breeding they will be spotted and identified by myself or someone else watching them.

ringing afternoon

After a nice restful morning, I ventured down to the New Passage, by the Severn Estuary to do some bird ringing. I met with Paul who helps me out and set up the nets in record time. Sedge warblers were singing everywhere!! Despite having them cornered we didn't catch a single one. Instead we caught two blackbirds (which we think were migrants rather than local), four reed warblers (males and females) and three dunnocks, including one which I ringed as a young bird last August. Swallows and house martin flew overhead, a lesser whitethroat sang out from nearby brambles and baby coots could be heard from the nearby pool. A lovely afternoon indeed and we packed up as the temperature dropped and the wind speed increased. Meanwhile, the view from my flat is glorious - all the trees are in leaf and everywhere is looking vividly green.

ringing baby ringed plovers

This warm weather has been great for our spring migrants. Now the prevailing wind has gone from north to south, many of our spring migrants should have an extra boost as they make their one into the UK.
After a wonderful bird ID walk I was leading on the Downs yesterday I had a lovely walk with a friend down at Chew Valley Lake. Reed warblers were singing away, busily setting up new territories - my first ones this year.

I then zipped back to Bristol to help Lyndon Roberts ring a family of one day ringed plover chicks - there were four eggs, but two disappeared, and the remaining two hatched!! They were incredibly difficult to see - their cryptic colours hide them very well indeed!

I then went off to try and ring some raven chicks in a quarry - sadly the nest was empty. We think the young may have been predated and saw the parents nearby but they weren't showing any interest. Got some good views of a peregrine though in lovely evening sunlight.

Robins for the One Show

All set for colour-ringing robins as part of an experiment for the BBC's One Show to be shown before Christmas. We're seeking to find out more about the soap opera of robins living in a suburban neighbourhood in north Bristol - who knows what we might discover! Under my licence with the British Trust for Ornithology I'll be catching some robins in a mist net and Potter traps (small cages) and then carefully putting colour rings on their legs so we can identify them as individuals. They will then be released to carry on their lives as normal. Hopefully we can find out who's who, what territories are being set up and where, who may be passing through and how many are visiting the gardens. The unset traps are in place to allow the birds to get used to them in the gardens. Hopefully they will use them when we film on Monday - we're hoping to ring at least 6-8 robins if not more.
