17/05/12 - Have we got NEWS for you!

We've had quite a busy time of late (and there's not even been much ringing involved!). The LDV base has been under the spotlight during the last week as we've had the pleasure of filming two pieces for the BBC about the LDV Whimbrel project and the work of Natural England in the Lower Derwent Valley NNR.

The first one was in relation to the Wildlife Trusts and their centenary - and the recent focus on 'living landscapes' and 'making space for nature' - the Lawton report and the Rural White Paper. Sir John Lawton - chair of the working group, author of the above report and perhaps most importantly a local birder, joined us at the Whimbrel fields to track the Whimbrel and discuss the importance of our work. The footage taken by the BBC was aired on the BBC breakfast news and Radio 4 yesterday (Wednesday 16th May) - click here to watch it on the BBC website.

The BBC interviewing Craig

Just as we'd finished with that piece Craig took a call from the Natural England press office to say that Countryfile were also interested in covering the story - they'd planned on filming in Yorkshire - covering the River Derwent and upper Humber and whilst researching the Derwent they'd come across our ringing blog! Unfortunately this came right at the end of the Whimbrel staging period and because of this there was some nervousness around whether we would be able to find any birds, let alone catch them, but after a quick chat with the producers it was decided that we'd come up with a good storyline whatever the outcome! 

So on Friday afternoon we met up with the Countryfile team at the NNR office at Bank Island, and then went on to spend three enjoyable hours wading through the floods(!), putting up a few nets, ringing a few ducks and radio-tracking the few remaining Whimbrel. The water had come up a great deal since the day before when Dean, the producer, had visited the site - just one day later and the area that had been earmarked for filming was underwater - and so it was a wader job for everyone - there were a few pairs of wet feet(!) but everyone was in good spirits which made it an enjoyable afternoon, and it was especially great for us to be able to share what we've done and been able to achieve.

Final interview - job done! 

So for another chance of seeing the great work that is being and has been done by Natural England in partnership with other organisations, the ringing scheme, local bird watchers and volunteers in the Lower Derwent Valley NNR, tune into Countryfile on Sunday 27th May!

Whilst waiting for the Countryfile team to arrive at the office we checked a few of the nest boxes around the base, a good number of  Tree Sparrows were sitting on eggs plus a single Blue Tit. We also checked the holes in the Ash tree that the Jackdaws have been nesting in for the last 10 years - in previous years Barn Owls, Tawny Owls & Little Owls have also nested in the holes! This year it seems to be home to just the Jackdaws, we found two active nests, one with two chicks in and the other had three eggs. The chicks were big enough to ring which was pleasing!

We plan to have another go next week to see if we can access the higher holes, and maybe even catch the adults - if we're quick enough!

10/05/12 - We think it's all over...it is now!

During the last week as a result of lots of hard work and help from local birders, we've had another fantastic number of colour-ringed Whimbrel spotted around their favoured fields in the Storwood area and elsewhere on the reserve. A total of 13 'new' birds for this year have been seen during the last seven days, including 11 birds still present that have been seen previously this year - some numerous times, inparticular Yellow/Yellow-Orange! This bird has been with us since April 20th, the average stay for a Whimbrel in the valley is just 8 days, however this one remained in the area for 14 days (we think) as it was last seen on May 3rd.

What has also been noticeable towards the end of the roost period is that some of the new arrivals have been the birds that were caught in the last catches of 2010 and so it fits with them arriving back now in subsequent years. Indeed it appears that 'early' birds arrive back early each year and those caught or present later in the spring also come back later each year (see previous post on just how arrival dates are so specific).

We've now also had two birds sighted that were originally ringed seven years ago during 2005, when the project was only in its second year. How far it's come since then, with over 100 birds now colour-ringed, and with 30 of those sighted during the last three weeks. It's been a great effort this year which has furthered our understanding of staging Whimbrel in the UK.

Thanks to everyone who has worked alongside us to make this project happen this year and over the course of the last 8 years - those that have helped catch and ring the birds, those that have monitored the roost site to obtain counts and identify where to put the nets, those that have read colour-rings and tracked birds in the field and all our partners who have had a role in making it happen in one way or another alongside Natural England - Yorkshire Wildlife Trust, Carstairs Countryside Trust, BTO and the RSPB. Only the last handful of birds remain now and many of the birds listed here will already be in Iceland or northern Scandinavia. We're already looking forward to them coming back next year - but hopefully we'll get some re-sightings away from the valley this year aswell.

09/05/12 - Trap happy

During the last couple of weeks several Wheatears and Yellow Wagtails have been reported around the Ellerton/Storwood area - a favoured location of passage birds moving through the valley. However, having been so busy we've not had time to act this, but on Wednesday afternoon whilst out Whimbrel'ing we finally managed to call in at Ellerton where the birds have been regularly seen on the local muck heaps. On arrival a female Wheatear and a stunningly bright male Yellow Wagtail were present. Soon after the traps were set two male Wheatears were also spotted - these two birds were much more interested in the mealworms and only a short time later the first bird went in, a stunning male!

Greenland Wheatear - first year male

We aged this bird as a first summer due to the buff edged juvenile coverts (amongst other features). It was also completely full of fat, (fat score 4), indicating that this bird is likely to be on the move soon to its more northerly breeding grounds. Wheatears usually appear in the valley between mid March and late May in spring, and with birds from early May onwards often presumed to be of the race leucorhoa, the so called 'Greenland Wheatear', breeding in Iceland and Greenland. They tend to be slighter larger and brighter in the field and also tend to have a more elongated, upright stance than European breeders. This bird was definitely a leucorhoa race  with a wing length of 108mm, (the range for Greenland is 99 - 110mm) and for the nominate race it's between 93 and 102mm. 

Whilst waiting for the other Wheatear to (hopefully!) go in the trap we noticed a pair of Lapwing in the field opposite, the adult female appeared to be behaving in a manner which suggested she had young chicks nearby. The scope had already been set up looking over the field for Yellow Wagtails, another look through it resulted in spotting two young Lapwing chicks on the dirt track that went down the middle of the field, result! A quick sprint from the van ensued, and after a search through the crop we spotted the two young chicks that had sat down on the ground, almost perfectly camouflaged with their pebbley coat.

Lapwing chicks - hiding!

These chicks were believed to be 5-7 days old, and so too small for colour-rings. We hope to come back next week though to colour-ring them - if we can find them!

To finish the day off nicely we went on to catch a second Wheatear, another young male, also full to the brim with fat (fat score 5) so even more so than the last one, he'll definitely be on the move soon! Another Greenland race bird, and with a wing length of 110mm and with all that fat, he's almost certainly off to the far north of the range.

Greenland Wheatear - first year male

April - summary

Well, it's been a poor month for waterfowl - partly expected though as the wintering birds have declined and the breeding birds are nesting, but the ringing totals have also been driven largely by the floods during the second half of the month.

We only managed 31 waterfowl for the month, but an impressive 740 for the year! 19 new waders were also caught, and they were all colour-ringed excluding the Oystercatcher. We also re-trapped 2 additional Redshank and added colour-rings, and managed to read off 5 colour-ringed Black-tailed Godwits, and controlled one of them (details still to come). Since the Whimbrel arrived, between April 20th and the last day of the month we've re-sighted 17 birds from previous years and caught two which now have colour-rings - hopefully they'll return and be sighted next year!

2012 colour-ringed Whimbrel

A few noteworthy additions for the month - 1 Tawny Owl, 1 Little Owl and 2 Skylark. So only 54 birds birds ringed but some really good data generated this month, especially all the re-sightings of colour-ringed birds - and that's why we do it - to get the data which we can then direct back at reserve management and conservation programmes. Thanks to all the local birders who've also put the time and effort in this month looking for Whimbrel and sending us their colour-ring sightings.

01/05/12 - New month & we're off!

Well, May has arrived but looking at the floods throughout the valley today, the scene is more typical of mid January. Obviously we won't be doing much duck or wader ringing for a while and it's likely to be a poor breeding season with virtually all the nests wiped out during the last 10 days. Hopefully we'll get a second flush of breeding attempts and we'll still be able to get our usual and valuable sample of local ducklings ringed. Below is a photograph taken from the air of Wheldrake Ings, showing the extent of the flooding.....

Wheldrake Ings - The Big Flood - April 2012

Today, the BTCV were working on Skipwith Common NNR stock fencing a few areas of reedbed to prevent grazing by Exmoor Ponies, Longhorn Cattle & Hebridean Sheep. They did a sterling job last time they were working with us on Skipwith & last month they also helped to make 59 Tree Sparrow boxes which are now up around the valley - & being used! It'll soon be time to check them!

Longhorn - Skipwith Common

In the meantime, we erected two wader nets (slightly larger mesh) in an area of short scrub nearby, that has been frequented by a Cuckoo over the last week. Less than an hour later and BINGO - one male Cuckoo was swinging in the net!

Male Cuckoo

What a truly amazing and beautiful bird, a real treat to see up close and even better it was enjoyed by all the volunteers who were out today. This is the third Cuckoo to have been ringed in as many years in the Lower Derwent Valley/Skipwith Common NNR's. You can follow the amazing migrations of the five BTO ringed and satellite tagged Cuckoo's here. Only between 40-50 Cuckoo's are ringed each year in the UK, and so each one caught is valuable.

The BTCV guys enjoying the close view!

A quick trip to view the floods after work at Wheldrake Ings YWT resulted in a surprise catch in the carpark - we say 'carpark' but it's actually part of the river at the moment, with about 3ft of water flowing through it...Anyway....a quick change into waders resulted in an adult male Wigeon hand-caught amongst the vegetation! There didn't appear to be anything wrong with it and it flew strongly on release - perhaps it was just taken by surprise to see a Landrover driving through the water towards it!

View from the bridge looking on to Wheldrake Ings

And finally......working late at the office tonight provided the opportunity to erect a single wader net across the office wildlife garden, to try and intercept one of the local Tawny Owls that has taken to screaming from the office roof each night during the last few weeks! And sure enough, after an hour or so....one found its way in, a nice adult male.

Adult male Tawny Owl

All in all, a rather nice start to the month!

30/04/12 - Into the tree tops...

On Monday the weather came good at last and so it allowed us to visit the heronry to see how the chicks were getting on....after all the heavy rain and rather low temperatures during the last couple of weeks we weren’t too sure how the chicks would have survived and whether the adults would have been able to keep them warm enough. On arrival it all seemed very quiet, whereas the last time we were there 13th April -  we could actually hear the young birds from the path, however as we entered the woodland their noisy call greeted us and so we quickly got to work! Neil & Eve from Lewis Tree Surgery kindly offered their services and came to our assistance, sending two climbers, Jamie Ulliott & Colin Kirby who did a brilliant job and climbed 14 trees, lowering the young up and down safely in the short time we’d given ourselves in there (to try and minimise disturbance and allow the adults back on the nests). 

The guys in action

 

 

Once the birds were safely lowered down we did the rest and cracked on with ringing them before they were safely put back in the nest by the guys who patiently waited in the tree tops whilst we were busy on the ground!

 

Due to the delay in us getting back to the heronry because of the bad weather, four nests contained two young each which were too big to risk disturbing, but we were able to ring 10 chicks, and five of those had darvics (colour-rings fitted). Grey Herons are the latest bird to be added to the Lower Derwent Valley colour-ringing scheme, and hopefully one which will bring many sightings, either from around the valley or further afield! The rings are yellow with black numbers ranging from 01-99.

Jean & Lucy with two chicks fitted with darvics

 

Despite the extremely wet and windy weather and extensive flooding, the birds seemed to have survived it well, with only two small dead young present, and the condition of the remaining chicks looked good. Hopefully if the weather allows then we'll be back at the heronry next week with another visit to ring the young that were too small to be ringed today.

We’re extremely grateful to Jamie & Colin for a great job carried out with good humour - given the smell and stabbing beaks! It’s something a bit different for them anyway! 

 Job done!

29/04/12 - The valley goes under....

Over the weekend the rain continued to fall, with Sunday being particularly heavy, resulting in the river finally going over the floodbanks at North Duffield...... 

North Duffield Carrs goes under...

Despite the weather Craig spent the weekend scoping Whimbrel and tracking the radio-tagged bird from Friday night. Spells of light rain on Saturday allowed reasonable scoping views and resulted in 6 ‘new’ sightings of Whimbrel, plus 2 already seen this year (L/L-Y, L/R-P). Sunday’s poor conditions made viewing the birds difficult but Craig did manage to read off another new combination for this year. Details of the new birds for 2012 are listed below, we’re now upto 17 colour-ringed Whimbrel sightings since their arrival two weeks ago – this is the most returning birds we’ve recorded in one year since the project began back in 2004! 

Craig managed to track the radio tagged Whimbrel pretty much none stop over the weekend bar losing it for a few hours on Sunday. It took him to a new roost site, presumably chosen due to the fact that the birds had been flooded off their original roost site (Wheldrake) followed shortly after by the second site they had moved to (Thorganby) which went under on Friday night. It has also led us to two new fields that we haven’t seen used in the past (but they may have been, we just haven’t known about it!) as well as several other fields used over the years.

New colour-ringed Whimbrel sightings for 2012:

From the 100 birds colour-ringed since 2004, we have now had a re-sighting rate back at the roost in a subsequent year of over 50% - a fantastic result with probably in the order of 200 individual re-sightings.  Interestingly, we’ve just had the one re-sighting away from the valley - a bird seen on the Ythan Estuary two autumn’s running.

27/04/12 - ‘E’...what a night!

After another week of Whimbrel scoping we went out again on Friday to look for any new arrivals, throughout the day over 40 Whimbrel were seen, including 3 colour-ringed birds - Y/Y-O & R/R-R which have been seen a few times over the last two weeks, but the third was another ‘new’ one for the year - W/Y-P (originally ringed in 2010 - no sighting of it since until today!).

The Whimbrel were flitting between Storwood & Thorganby again (due to the flooding), they were joined at Thorganby by 90 Black-tailed Godwits – four of which had colour-rings which we managed to read off, hopefully we’ll hear back shortly where they were originally ringed, we’ll post the details on here when we find out. There was also a supporting cast of 6 Dunlin, 2 Ruff, 2 Greenshank, 1 Common Sandpiper, 2 Green Sandpipers, Black Tern & 3 drake Garganey! Not a bad selection!

We started to set the nets up around 4pm which took 2 hours (there was only two of us!) to set two lines - totalling over 1000 foot of net! Whilst we were setting the nets most of the Whimbrel and all the Black-tailed Godwits were still present in the field. By 7pm, 45 Whimbrel were back in the ‘catching area’ and things were looking good with birds behind, infront and even underneath the nets. Numbers increased towards dusk with 78 counted before the light was too poor to keep a track of the comings and goings. It was however a rather light night and it seemed to take ages to get dark enough to consider going round the nets, which we finally did around 9.30pm.

It seemed rather quiet as we walked the edge of the Ings and it was clear that the water levels had risen....whilst it wasn’t a concern catching wise, we were worried that it may have further unsettled the birds that had been unable to settle into a regular routine over the last 10 days due to the flooding. However, whilst it appeared that the rising water levels had indeed moved the birds on, two Whimbrel were caught which allowed us to fulfil our aims of fitting one with a radio tag in order to locate more of the daytime feeding sites away from the protected reserve and to try and follow the roost site/roosting behaviour during the floods.

We also caught a nice summer plumage Black-tailed Godwit which was actually one of the colour-ringed birds that we'd seen during the day, what a bonus! & to top off a night of 'E' rings we also caught a Little Owl in a nearby hedge whilst we were waiting for darkness to fall - a female with a brood patch, the male was nearby too so hopefully there will be some even littler Little Owls to ring soon!

The radio tracking of Whimbrel has been very useful in allowing us to locate and map the feeding fields outside the designated site. As we said in an earlier post, these are largely extensively managed pastures, usually cattle grazed, on a specific soil type. The map below shows an example of the data collected over the last eight years.

Whimbrel map

This data has allowed these fields to be targeted with agri-environment schemes to ensure suitable management for the continued appearance and use by the Whimbrel - a great example of science delivering direct nature conservation action on the ground. It also gives a real life example to concepts such as 'living landscapes', 'making space for nature' and 'nature improvement areas' - landscape scale conservation. We filmed some of the catch and tagging of the Whimbrel as requested by the BBC, which should hopefully appear on the news sometime this week....Wednesday or Thursday possibly!

Having a tagged bird amongst the staging birds also means that we are often lead to the fields used by the other feeding Whimbrel - thus allowing more targeted effort in reading colour-rings and getting re-sightings and length of stay data.

Craig & Mike fitting the radio tag

Hopefully this bird will come up trumps and give us an insight into where the rest of the birds have been feeding this year!

26/04/12 - More Whimbrel....more water....

It’s probably fair to say the UK has been experiencing a bit more than April showers during the last week or two! The rain has continued to fall and increased flooding in the valley, Wheldrake is now in-accessible as the carpark stands under 3 foot of water. Ellerton is currently looking more like a lake than a field and the river at Bubwith bridge is looking rather full (a few photographs can be seen at the bottom of the post).

Wednesday (25^th) was a particularly poor day weather wise, with torrential rain for the majority of the day making it impossible to pick out any colour-ringed Whimbrel. Despite the bad weather Dave went to the roost at Thorganby and counted 38 birds.

Thursday (26^th) was a much better day and the weather allowed great views of the Whimbrel in the fields at Storwood and Thorganby which resulted in 4 ‘new’ birds for this year, plus 3 already seen (O-Y/Y, Y-L/L & R-R/R). Craig & Dave went to Thorganby in the evening & counted 46 birds coming in to roost - the highest count yet. The details for the four new birds from Thursday can be seen below:

Whimbrel: Yellow - White/Yellow

2009 - Ringed on 29^th April.

2011 - Re-sighted by PR on 19^th & 27^th April.

2012 - Re-sighted by CR on 26^th April.

Whimbrel: Orange - White/White

2006 - Ringed on 23^rd April, re-sighted on 8^th May.

2012 - Re-sighted by CR on 26^th April.

Whimbrel: Pink - White/White

2010 - Ringed on 19^th April, re-sighted on 2^nd May.

2012 - Re-sighted by LM & CR on 26^th April.

Whimbrel: Pink - Red/Red

2010 - Ringed on 19^th April, re-sighted on 2^nd May.

2012 - Re-sighted by LM & SH on 26^th April.

25/04/12 - Whimbrel: Three more returnees!

It’s been a strange spring with some individual spring migrants appearing very early whilst the majority of them are still to arrive, most are thought to be waiting in Spain and southern Europe having been held up by a weather front. It’s affected lots of migrants but it appears to have held up the return of the Whimbrel too. So far it’s been more of a steady arrival than usual but numbers are slowly building up, and it just means we have to work a bit harder to try and find them and read colour-rings in the longer grass when they do return! 

At the weekend Craig was out & about around the valley looking for Whimbrel and on Sunday he managed to pick out a new colour-ringed bird for this year (Orange - Lime/Yellow, originally ringed in 2006) as well as the three also seen a few days ago. On Monday Lucy scoped the fields around the Storwood area and had 13 birds - four of which had colour-rings including yet another new sighting, Pink - Lime/Red, this time a bird originally ringed in 2010.

Yesterday (Tuesday 24^th) we had the highest count so far this year, with atleast 28 birds counted throughout the valley. Lucy & Jean scoped the fields around Storwood and Thorganby and picked out three colour-ringed birds, two already reported this year but another new one was also present: Red - Red/Red, originally ringed in 2008. Below are the full histories for the three 'new' colour-ringed Whimbrel.

Whimbrel: Orange - Lime/Yellow

2006 - Ringed on 5^th May.

2011 - Re-sighted on 29^th April.

2012 - Re-sighted on Tuesday (24^th April) by LM/JT.

If the passage runs as normal we are now about a third of the way through. Although the number of birds present is low  (about half the normal number expected for the date), 6 of the 100 colour-ringed birds ringed since 2004 have been seen so far this year, compared with 14 during the full roost period during 2011. It may well be that there are more birds out there that we don't know about or haven’t seen yet, so there’s still plenty of checking to do. Also, there have been years in the past such as 1992 and 1997 when the peak numbers were much later than usual - 6th and 9th May, so numbers may reach a sizeable peak yet. There is some suggestion from the bird information services that birds are finally reaching Britian, with 52 at Rye Harbour on 23^rd April (another spring passage site) and larger numbers moving through other sites. We also heard from Peter Roworth on Monday (23^rd) and 10 were present at Saltfleetby & Theddlethorpe Dunes NNR.

Several evenings have been spent at Wheldrake waiting for the birds to come into roost, however due to a large part of the valley being flooded at the moment (see photos below) the Whimbrel are unable to come in to roost at this traditional site. Their behaviour is completely different this year and mirrors that of 2004 when we last had a large spring flood during the roosting period. It is also making it hard to count the number present as we yet don’t think we’ve found all the daytime feeding birds or been able to count them accurately at a single roost - watch this space for further updates....

A flooded Bank Island - 20th April 2012

Below is a view from Swantail Hide on Wheldrake Ings (traditionally the favoured roost site for the Whimbrel) - this photograph was taken almost two weeks ago and since then with all the rain that has fallen (55+mm) the whole site is completely flooded, we couldn’t even get to this hide to take a comparison photograph!

The floods have undoubtedly caused heavy losses to many breeding waders and some waterfowl nests have been lost, but we’ve also seen the first Greylag and Mallard broods appearing. The wetter conditions have also proved attractive to other species with over 200 Tufted Ducks arriving in recent days. We’ve also seen two Black-necked Grebes appear so it may be a good breeding year for them again - keep an eye out for a forthcoming post on the results of our Black-necked Grebe colour-ringing project - we might even get the chance to extend it this year!

Rather wet drought conditions...!!
