Greenish Warbler Update




After the reaction of some very experienced birders and ringers on Twitter regarding photographs posted by myself and Steve Rogers I decided to try and do some more research on the Greenish Warbler at Porth Joke. I had heard that Steve Rowe had some recording of the bird singing and he very kindly supplied me with the original recording. The next step was to contact a very helpful Martin Cade who gave me contact details for Magnus Robb from Sound Approach team and his colleague Roy Slaterus who has recently been working on the first Green Warbler for Holland. (interesting article on this bird here: http://www.intobirding.com/greenwarbler.html)

Both Magnus and Roy quickly replied to me and I was delighted that they would help analyse the recording and get back to me with their results. In super quick time I soon had two excellent and informative replies from these sound experts with detailed notes and a sonogram which seems to suggest that the bird was in fact a Greenish Warbler. Snippets from their email include:




Roy Slaterus :

Yes, I agree. This sounds like Greenish Warbler song to me. These are things I look at, when separating Greenish from Green.


-          A short high-pitched ‘jeet’ at the very start of (almost) every song phrase is typical for Greenish. This intro note is lacking in Green. But I can see it in the Porth Joke recording.


-          The song of Greenish is usually broken up into sections, like Magnus explained. Vaguely reminiscent of Wren or even Chaffinch (in Dutch: ‘vinkenslag’). In Green this is less obvious. But I can see it in the Porth Joke recording.


-          Greenish Warbler song consists mainly of rather simple elements and descending notes are dominating, whereas Green Warbler song is a bit more rich with more V-shaped notes. The Porth Joke recording is similar to Greenish in this respect (if my judgement is correct; the recording sounds a bit affected in some way).


Many Greenish Warblers sing longer song phrases than those recorded at Porth Joke. But it is within variation, I would say.

Magnus Robb:

I think this is really a bona fide Greenish Warbler. Lets see if Roy agrees. It sounds like several examples I have recorded and it doesn’t those of Green that I have just been listening to. The structure has a very slight hint of Wren about it, in the way it is broken up into sections whereas Green has less contrast in frequency range etc within the strophe. Also, as Roy recently pointed out to me, the little intro note just after 13 seconds is typical for Greenish whereas Green doesn’t have it.





In the mean time Steve Rowe remembered a post from Portland Observatory of a Greenish Warbler trapped in June. It was very interesting to see that the bird in the hand showed plumage characteristics pro Greenish (such as a grey cast to the mantle and white looking underparts). Yet the image of the bird in the tree's depicts a bird that looks much brighter and yellower especially around the face so I can only imagine that perhaps the Porth Joke bird was affected by the light and the green foliage in our photographs as in the field it looked much whiter underneath and showed a contrast similar to Wood Warbler between head colour and flank, underpart coloration.  A link to this post is here: http://www.portlandbirdobs.com/2017/06/1st-june.html.

Comments I have heard about the structure of the Porth Joke Greenish being too weak billed may have some relevance but I wouldn't put too much onus on this feature. My ringing experiences have taught me that there is much overlap with biometrics in Phylosc Warblers. Another interesting comment from Kester Wilson was that Greenish Warbler seems to show much more solid dark lores (which the Porth Joke bird shows) in comparison to the relatively plainer faced Green Warbler from images on the internet.



So in the end it does seem that the bird was a standard Greenish Warbler Phylloscopus trochiloides. A great record for Cornwall this spring and a really good find for Steve Rowe. I certainly feel more prepared should a Green Warbler turn up again in Cornwall and I have learnt that the Greenish complex is more difficult than I realised. Good photographs from a series of angles in good light are vitally important to determine positive ID yet field observations and notes are just as important as they have always been in order to compliment the pictures and prove that they are accurate as all cameras can show different hues and colours on a bird. Sound recordings of calls and songs are going to become more and more important in separating difficult passerines and when possible I am definitely going to make more of an effort to get sound recordings. Birds trapped and ringed at migration sites and observatories will also add to our understanding through DNA analysis and in the hand descriptions. With a Green Warbler turning up on the Lizard this year and with an autumn bird on Lundy last year us birders should always keep an open mind with what can and will turn up in Cornwall.

A Special Thanks to Steve Rowe, Magnus Robb, Roy Slaterus and Kester Wilson for their help, knowledge and ideas.

'Greenish' Warbler at Porth Joke


I thought I would share my photographs of the Greenish Warbler at Porth Joke on June 9th found by Steve Rowe on his local patch . I was happy with the ID whilst watching it however suspicions have been raised on Social Media from birders I have a lot of respect for  (regarding Green Warbler) and who would have more experience than me on Leaf Warblers  so I thought I would share all the photographs I took for everyone's benefit. All photographs are unedited and uncropped.

The African Pied Crow in Cornwall


Going to see the Pied Crow at Lands End yesterday inspired me to do some research about the species and write about this eye catching corvid.



African Pied Crow in Cornwall

Widely spread over Sub-Saharan Africa this conspicuous corvid with white collar and breast contrasting with overall black plumage was first seen in Britain at Spurn Point; East  Yorkshire in June 2018. After it was seen in Norfolk it journeyed over 300km to Clevedon, Somerset on 26th June. It’s next port of call was the village of St Justinian Pembrokeshire in July 2018 before heading back to the east coast village of Flamborough spending the winter of 2018 settled at this site. In 2019 after a prolonged stay at Flamborough the bird moved down the coast to Sussex before making another long-distance journey to West Penwith (first of all seen flying along the coast at Cot Valley) before settling at Lands End on 10th April. 



The east coast arrival and subsequent urge to head west is rather interesting behaviour and could be seen as a natural reaction typical of a long distance or (perhaps more likely) ship assisted vagrant trying to relocate. The status of Pied Crow in the Western Palearctic is also interesting with birds now accepted as genuine vagrants in Morocco, Libya and Western Sahara (attempted breeding even took place in this area in 2010). Evidence of Pied Crow using ships to reach the Western Palearctic comes from Iberia and notably Gran Canaria where three birds at Puerto De La Luz were found to have originated from an oil rig that had been moored off of the Mauritanian Coastline. Closer to home several sightings from Holland are thought to have involved ship assisted birds. The corvid family seem prone to using ships as a means to venture much further from their breeding range and even in some cases establish new territories in new geographical areas. I’m reminded of the House Crow (originally occurring in South East Asia) which has established colonies in Egypt and Israel by means of this method and has reached Western Europe via ship with accepted records from Holland (recorded since 1998) and Ireland (Cork 2010). 




Whether we will know for sure the origins of the British Pied Crow with any certainty is unlikely. Even if the bird was trapped and isotope analysis of a dropped feather carried out this would now prove nothing as it would have now completed a full moult in the UK. It does however seem that it is a very rare and desirable cage bird which is not easily available. I decided to take a look at how easy they are to buy as a pet and it would appear that they aren’t at all. A website in America offers hand fed babies at a staggering $3500 each whilst in the UK they simply don’t seem to be available at present. Somebody from the UK enquiring on a forum as to whether it was a good idea to have one as a pet only had responses from U.S.A telling them to look for a cheaper and easier alternative.

In the field I found the Pied Crow to be approachable yet wary and no tamer than any other corvid at the complex. My experience with pet corvids is limited but I do know that they can become amazingly tame and are trained to mimic sounds and words. They will outgrow their natural behaviour very quickly due to their intelligence which cannot be retrained.

In conclusion my own theory would suggest that this bird is of ship assisted origin but I would be happy to learn from any more information that may be out there. I’m sure that many of our true mega rarities in the UK are ship assisted without us knowing. For instance, many Nearctic passerines may well have come off of a boat you only need to look at where they turn up. Personally, I think it should be fine to count them regardless as the bird is still wild and has just used its survival instincts which I think is pretty special.  

Thanks to Kester Wilson and an interesting article on Birdguides by Sam Viles for some of my facts and ideas. Also Crows and Jays by Madge & Bunn.

New Years Day CBWPS Green Bird Race

A day of car free birding around our local parish and a race to see how many birds me and Libbie could see in 24hours

Yellowhammers seem to have a healthy population where I live we saw 14 during the day

At only just past midnight whilst most people were probably out celebrating me and Libbie had just got ready for bed and could hear a Song Thrush that had been woken up by the local firework display , the first bird of 2019! Our bird list for the day was underway but we soon drifted off to sleep in readiness for an early start ( although I did wake up at 5:30am to the sound of a Pheasant calling away)

Well before dawn we were up and ready and heading out at 7:15am and although it was pitch black a Golden Plover flew over calling just above my house and as we headed over to the local farm we were delighted to hear both Barn Owl and Tawny Owl , a great start! Soon some passerines started to stir from their slumbers and Libbie heard a Robin singing and a Crow calling from the copse. A snipe flew over and as the sun came up a group of Yellowhammers flew out from their roost. We headed home for Breakfast and to help my Mum for an hour or so but that didn’t stop us adding more birds to the list!


With the feeders topped up we enjoyed seeing Coal Tit , Chaffinch , Great Spotted Woodpecker and Starling and also whilst I fed my pets a Bullfinch flew over calling and some House Sparrows were busy eying up the chicken feed. 


The Countryside around my house is very good for woodland birds with lots of mature tree's

The local pond has an excellent small reedbed- even Bittern has been seen here in the past

Now was time to set off for our marathon walk all around the local area and what a brilliant day we had! All the birds seemed to be so showy and we had some nice surprises of some scarce birds for the local area. Our first visit was to the local village pond where we saw a Canada Goose as Goldfinches fed in the Alders and Libbie had her first views of a stunning male Bullfinch. We then headed to the local sewage works enjoying a few Common Chiffchaffs and a very showy Dipper for Libbie. We carried on across farmland and fields adding a solitary Skylark and a surprise group of 10 Fieldfare, whilst ten Buzzards gluided together over a Pheasant Farm.

We were pleased to see 2 Marsh Tit's during our walk


After a brief encounter with the New Years Day Hunt in the middle of a wet valley with trumpets blowing and hounds everywhere ( why do these things happen to me when I am out birding!) we arrived in the hamlet of Talskiddy. Birds seemed to be everywhere with Redwings and Starlings filling the fields and a Marsh Tit on a garden birdfeeder being a highlight. We soon arrived at the local pond which is always an excellent place to Birdwatch and our gave our only chance of some waterbirds. Two Cormorants were a good local record and a Moorhen , 2 Mallard and a Grey Heron were good padders for the list. The real highlight ( especially for Libbie) were 4 very showy Water Rails feeding on the flattened reed bed. Time was beginning to run out so we stomped up to Trewan Hall ( a local Manor House ) and scanned the mature tree’s. Luck was again on our side as two Great Spotted Woodpecker, at least 4 Nuthatch , 1 Treecreeper and a Mistle Thrush all showed well. As the light began to fade we positioned ourselves overlooking the valley behind my house hoping for a Woodcock , sadly nothing was doing but a flyby Common Gull going to roost and 3 Roe Deer more than made up for it.

Goldcrest in Black & White

It was great to see so many Song Thrushes today with at least 20 sited


We walked 8 miles and saw 55 species of birds as well as many different tree’s, plants and fungi. It just goes to show that sometimes the best place to visit for nature are right on your doorstep….




Birds: Woodpigeon , 2 Stock Dove, Collared Dove, 6 Great Spotted Woodpecker, Jay, Magpie,Raven, Rook, Carrion Crow, Jackdaw, Long-tailed Tit, 2 Marsh Tit, Coal Tit, Great Tit, Blue Tit, 4 Nuthatch, Treecreeper, Robin, Pied Wagtail, Grey Wagtail, 120 Meadow Pipit, Skylark, 1 Golden Plover, 1 Barn Owl, 1 Tawny Owl, 1 Dipper, 10 Fieldfare, 60 Redwing, 20 Song Thrush, Blackbird, 3 Cormorant, Mistle Thrush, Common Gull, Black-headed Gull, Herring Gull, Goldfinch, Chaffinch, Chaffinch, Bullfinch, House Sparrow, Dunnock, 14 Yellowhammer, Starling, 3 Chifffchaff, Goldcrest, Wren, Canada Goose, Mallard, Common Snipe, Grey Heron, Moorhen, 4 Water Rail, Pheasant, 6 Red-legged Partridge, Buzzard, Feral Pigeon

Curlew Country Offspring Visit Cornwall

You know birding and ringing have many directions in this day and age and I love the pace! So many different avenues you can pursue and so many surprises can be had in this modern age of internet, mobile phones and social media. From large county and national year lists to  worldwide birding and ringing opportunities at the click of a mouse button! Yet yesterday I had an encounter that bought some nostalgia and emotion that I have not truly experienced for a long time and made me reflect on why I choose to get up so early in the mornings and devote so many hours watching and monitoring the birds of Cornwall and beyond!

At Hayle Estuary located near West Cornwall I found a colour ringed Curlew. As many regular readers of this blog will know colour ring reading is a passion of mine and I never tire of the thrill of finding out where so many of our species originate from. I have had some surprises in the past of long distance migrations and I have also learnt an awful lot of the origins and lifestyles of many of our birds. Waders are normally the most fascinating of them all and can be from just about anywhere in the world!  

The un-seasonal bright sun made photographing the colour ringed Curlew (at the back) very difficult! 
It was great to get such a fast response from Tony Cross of the Curlew Country project informing me that it was the first ever recovery of one of there captive reared birds released in Shropshire! It was originally released at Stiperstones National Nature Reserve on 20th July 2018, yesterday it was located nearly 200 miles away in a flock of roughly 100 other (non-ringed) Curlews at Hayle Estuary.


I was thrilled and decided to take a look at the project and find out why they had decided to captive rear Curlew. 


I must admit that I am guilty of glazing over many posts found on social media and online forums asking for help or headlining as the next species we might lose and fear I had done the same with this one! Sounds harsh but it is so frequent now that I feel many projects get lost in the doom and gloom of an ever increasing plea for help and money! Each year the RSPB and BTO seem to be asking for help for a never ending stream of species and get caught up in red tape and bureaucracy and for me the practical element often seems lame when compared with the money raised. Now don't get me wrong I am not criticising the organisations, they must have so many employees that go home emotionally drained, contemplating the future of our wildlife and wonder if it would be far more effective to by a gun and dispatch the decision makers of this country! I am also aware of the many success stories that this country has witnessed and the people who are responsible for these conclusions deserve to be triumphant victors in such times of turmoil! So, with that in mind it was refreshing to see the approach taken by the Curlew Project team. I whole-heartdly feel that the approach they are taking is a pioneering one and is the key to making a real difference moving forward!

Local communities, society's and organisations could be the saviour of so many species if given the  right structure and instruction to work with. A worrying rift between the farming community and the environmental sector ( I use the term loosely) has formed in recent years, some difference of opinions are always going to be there as that is the nature of the beast. However, I live in a rural community and know that most farmers or people that rely on the countryside for their living are as concerned as the birders amongst us for the welfare of our natural world. 

The Curlew Country website has a brilliant short film capturing the relationship between a retired farmer and the Curlew that use his farm and I would urge you to watch it here: Keeper of the Call Film

Tony Cross stated near the end of the film that this is merely putting a band aid on a wound that needs greater attention! That is the real dilemma and one that seems to be harder than ever to put right. But with the correct relationships and education I hope that the future will see the correct decisions being made and the chance for strong recoveries for many species in the UK.

Nanjizal Niceties

Last Sunday morning was my last trip to ring at Nanjizal for 2018. Always a bit gutting to think that the season is over but having caught just 18 new birds it felt right that the nets will be packed away for the winter months.

My ringing schedule in the County seems to work quite well. I am spoilt really as I have the opportunity to regularly ring at Nanjizal which is a fantastic migration route. But I also have my own regular patch, the Goss Moor which is one of the best locations in Cornwall for breeding species. I try to help out at Nanjizal a bit in the Spring and also do some ringing on the Goss Moor for the early returning migrants. I then switch my attention fully to the Goss Moor through the summer months to monitor the breeding species that reside there in June and July and into August. As Autumn kicks off the Goss Moor quietens down allowing me to once again turn my attention to assisting Kester Wilson at Nanjizal were large numbers of common migrants get ringed each season. As of today it is back to thinking about whats about on the Goss Moor and local vicinity's for the winter period! But not before some personal reflection on my encounters at Nanjizal this year! 

To find out more about the numbers and sightings at the is the exceptional place; I urge you to read the regularly updated blog found here: https://nanjizalbirds.wordpress.com/

Ringing in Cornwall during the Spring months is exciting and rewarding. It always throws up a good bird or two and my year started well at Nanjizal with two Wood Warblers in April. They are sadly very scarce in the county nowadays with only a handful of records each year and have not bred since 2000. So to get two on the same morning was most welcome! 


One of two Wood Warblers ringed and processed at Nanjizal in April, 2018.
As more migrants started to arrive my attention turned to the Goss Moor once again. However a trip to the Valley on the 3rd of June did produce a Spotted Flycatcher which likely attempted to breed on site. Another bird that is becoming a much rarer breeder in Cornwall!

A likely breeding bird! 
I did not return much to Nanjizal until the middle of August as the Goss Moor kept me out of mischief. However, amongst the large volume of passage migrants a "goodie" or two was lurking! On the 22nd I had my first taste of a local rarity in the form of a pristine Nightingale! An exceptional year for this species at Nanjizal and also in the county with at least 7 reports that I am aware of! They obviously bred well somewhere. The morning also produced my first Pied Flycatcher of the year which are always delightful to see. 

Nightingale is a very rare bird in Cornwall nowadays 


Pied Flycatcher seemed to be passing through Cornwall in reasonable numbers during 2018. 
The rest of the month seemed a bit of a blur and large numbers of common Warblers and migrants were processed as the weather permitted. Amongst them was a real splash of varied colours and species! 

Kingfishers seemed to be found at the site on a daily basis.

As were Grey Wagtails

This Green Woodpecker was a nice surprise and only the 2nd to be ringed at Nanjizal.

I was really chuffed to ring this Whinchat as it was the first I had ringed in the County! 
My biggest surprise happened on the 29th of August and will stay with me forever! I caught up with a lifer that I had longed and hoped for in Cornwall, especially being a ringer and regular at Nanjizal. After a reasonable morning for Sedge Warblers I was walking near a net that is set up for catching Locustella and Acrocephalus type warblers and contemplating how much longer I should carry on ringing as it had started to quieten down. My attention was drawn to a bird working its way through the low grass clumps and heading straight for the net. I held fire and watched as it flew out of the under growth and straight into the net and pocketed nicely. Naturally, I extracted the bird straight away suspecting another Sedge and was dumbfounded to see a large prominent gold central crown stripe! Finally, I had caught up with an Aquatic Warbler. I would have happily hung up my ringing pliers that day and gone out on a high, safe to say I was ecstatic! 


Aquatic Warbler is one of the rarest breeding Passerines in the Western Palearctic
making this encounter even more rewarding!
Kester recently updated that the annual total of birds ringed at Nanjizal during 2018 ended on 9082! Included were Blackcap 2843, Sedge Warbler 1648, Chiffchaff 946, Willow Warbler 602, Whitethroat 574, Grasshopper Warbler 139, Nightingale 6, Yellow-browed Warbler 16! Rarities were Melodious, Marsh and Aquatic Warbler. Iberian Chiffchaff x 2, Wood Warbler x 2, Red-breasted Flycatcher, Little Bunting x 3, Hoopoe, Wryneck, and a Spotted Crake!

It wasn't just the nets that produced for me. Due to the location of the valley it also has a consistent stream of flyover migrants and over the course of the year I also encountered Ortolan Bunting, Richards Pipit, Serin, Glossy Ibis, Common Crane, Dotterel and Turtle Dove, that's just the ones that I nailed and many more probables and possibles have been relinquished to the back of my mind!

I know you shouldn't wish your life away but I am already excited about the prospects of next years visits to Nanjizal and what they might bring.

Pied Wheatear and Sincerest Apologises

Let me start with my personal sincerest apologies! When Bob and I started this blog we promised ourselves that we would update it regularly and try our darnedest to keep it as interesting as possible. Sadly, due to commitments beyond our control it has fallen by the wayside. I have started writing many posts and then not been able to return to them and the moment has passed and the entries forgotten!   

In a bid to thwart this trend my plan is to start writing about our surreal year from now and work backwards to a point that I feel we are up to date once again. 

14th of November - Pied Wheatear at Trevose Head 


Pied Wheatear relocated at Trevose Headland

On the 10th of November pictures of a Pied Wheatear were published on a Facebook page. The person posting was well known to me and I strongly suspected that the bird was or had been in a local vicinity! I informed other local birders of my suspicions and the day after a handful of hopefuls went on the hunt around the Trevose Head area located near Padstow, sadly to no avail and it seemed that the opportunity to see such a local rarity was lost. After some more racking of locals brains it transpired that the bird was indeed located at Trevose Golf Course and due to it being on private inaccessible grounds was suppressed! A sad fact, but understandable.

Late yesterday evening I received an anonymous tip off that the bird had relocated to an area that was public and the bird seemed in good health and settled! Unsure what to believe I called Bob and hatched a plan to drag him away from his new found play pet (he has a real living girlfriend now), and to meet me at first light near the location to sort fact from fiction. I was a little early and it was still quite dark at the time but decided to get into position anyway. A short while later I heard some commotion from the road beneath me! It was Bob on his way up getting a barrage of abuse from the ex county recorder who sadly for many reasons unknown to me has become an avid suppressor and regards the National Trust headland his own private birding site! A difficult situation as for many years he was a firm friend and a fantastic teacher that turned both Bob and I into adequate birders. Sadly the suppression and competitive nature was too much and we both independently decided that such selfish acts were no longer for us and distanced ourselves from the foolery! It is nice to be able to see other peoples birds nowadays and occasionally turn something else up to share with others, but that is a story for another time.

Thankfully Bob managed to make a break for it and head on up to the location we had been given. Albeit, was closely followed by the angry suppressor. We quickly hatched a plan! Knowing that I was so far unscathed from the verbal obscenity we agreed that if Bob moved forward and located the bird I could be his buffer and between us we could relocate the bird and whoever was not suffering from the torrents of abuse could then slope off and get news out as far and wide as was possible! 

Bugger me the plan worked! We both got on the bird prior to the Suppressor Chiefs arrival and had good but brief views of the bird. I then tailed back a few meters whilst Bob went ahead and out of site to get the news out. A short while later Bob returned to the relaxing tranquil Cornish headland sounds of personal abuse and swear words and he was just in time as I was getting close to boiling point and today's twitching fraternity would have been greeted with a fantastic rare bird and a corpse!

Our deed was done and we both needed to get going as work was beckoning! It was superb to get so many messages and calls today thanking us for the news and effort and it made me realise what a great local and national birding community we all have the pleasure of being involved with! 

It was nice to see the bird managing to get plenty of quality local produce inside it! 
 I do not miss the old days when I wasn't allowed to tell anybody about anything and I often feel regret about the birds that so many people would have enjoyed if given the chance. At least things are different now! As a side note Trevose Head is now owned by the National Trust and is a amazing birding location with a superb track record that would rival any location in Cornwall. It can produce in all weathers as the sea-watching is phenomenal and so is the chance of just about anything else turning up. Have it on your radars! 

A bird that I will remember for a longtime for various reasons!
