The Wheatears are on the move, there were a couple of females that took a pitstop along the Cottenham Lode on the outskirts of our village while on passage south. They were first spotted on 18th August by friend Josh C, and Mrs Sciencebase and myself saw them on the 21st, although it was drizzly so I wasn’t carrying my camera. Here’s a male I snapped in May 2017 in Aldeburgh. Suffolk, Le Cul-blanc.
By the way, the name Wheatear has nothing to do with wheat, ears, nor ears of wheat, even. It’s from the 16th Century name meaning “white arse” as the bird famously has a white rump. The French call it the Cul-blanc. They used to be caught and roasted as seaside snacks on the South Coast in the 1700s. Apparently, half a million every year. I think I’ve seen fewer than a dozen in my whole life…but imagine a time when a bird that seems fairly rare was so abundant…makes you wonder where they all went…ah.
About a week ago, the birding wires were buzzing with news of a rare visitor to the British Isles – a European Roller (Coracias garrulus). It’s the only Roller to breed in Europe and you usually find them around southern Spain, the Mediterranean coasts and into the Middle East, Central Asia, and Morocco, rather than the British Isles. But, here was one perching on overhead powerlines that cross a farm alongside a busy stretch of Suffolk road.
Now, Mrs Sciencebase and myself love a bit of nature as you probably guessed by now, but we don’t tend to “twitch”, we rarely go out of our way to see a bit of wildlife, although it has been known.
European Roller, Coracias garrulus
Usually, we’d combine an off-patch twitch with another trip and so when Mrs Sciencebase mentioned she’d like to visit the Suffolk Wildlife Trust site at Lackford Lakes on our joint day off I agreed and then let her know about the Roller. Fortunately, the short, fast route we’d normally take had roadworks, so we took a diversion that just happened to go along the aforementioned Suffolk road near Icklingham.
We stopped off, just as had done perhaps 100 other birders, set up cameras and scopes and took a good long look at this beautiful and exotic bird that has some of the characteristics of the Jay, the Bee Eater and the Kingfisher, all rolled into one, as it were. When it wasn’t perched on wires or hiding in the hedgerow it was generally flying past us at about 200 metres distance. But, just as we were giving up on getting a decent shot it flew on to the wires about 100 metres away, sat for a while, did couple of barrel roll flights (hence the name) and then headed back to the hedgerow, so I did get a couple of half-decent in-flight photos of this quite exotic and unique bird.
TL:DR – Testing the Topaz AI software to sharpen, remove motion blur and denoise an otherwise unusable photo of a Peregrine Falcon.
I’m just giving Topaz Sharpen AI and Denoise a try-before-you-buy. I had some hastily grabbed photos of the Ely Peregrines, but the best of the bunch had quite a lot of motion blur and was rather noisy because of high-ish ISO and exposure compensation to get the underside markings of the bird against a bright blue sky as it flew overhead.
So, here’s the basic photo converted from camera RAW and close-cropped to a square to ultimately upload to the Sciencebase Instagram. It looks very grainy/noisy and the motion blur and shoddy focusing look irretrievable, to be honest…
I told Topaz that the photo is suffering from serious motion blur and is “very blurry” and let it choose the basic settings. It took several minutes to process the image but the output is quite astonishing…you have to admit!
Still noisy, but then I hadn’t asked it to clean up the grain, I used the separate Denoise AI software to do that, again with quite astonishing results just setting it to “standard” and letting it do its job. Denoising was very quick…
The final step was to go back to my usual photo editing package PaintShopPro to develop the image as I normally would and to add my logo…
That’s a pretty good result considering how shockingly bad the original unprocessed image was and perfectly acceptable for Instagram and other social media, I’d say, although probably not going to be good enough for National Geographic in any way, shape, or form.
The Topaz Labs software – Denoise, Sharpen, and others – can be found here.
Swift boxes designed and built by Dick Newell have now been installed by firefighters from Cottenham Fire Station on the new Village Hall and the sports pavilion with plans to install additional units.

The wooden boxes blend in well with the buildings offering executive homes for our summer visitors and augmenting the swift bricks that already form part of the fabric of the new Village Hall. The boxes have a smooth slot through which these slick and speedy birds can fly to build their nests.
Retained firefighters from Cottenham Community Fire a Rescue Station
Within each box is a ‘nest form’, Newell told me. Essentially the nest form is a square of plywood with a hole cut in it. He and his colleagues tested various designs, such as smooth cup-shaped nest forms against this simpler approach and found that the swifts showed no preference, so new boxes are built with the simpler design.
The large box installed in the gable end above the pavilion clock also has an electronic that plays back a recording of swifts calling in flight to encourage new arrivals to approach the boxes and ultimately build their nests within. Newell told me that the birds usually use spit and feathers to construct their nests and once they’ve raised chicks and flown back to Africa for the winter, the remains of the nest will be degraded by insects and mould.
Unfortunately, he adds in recent years, swifts have been found to use fragments of plastic they catch or collect and these fragments simply accumulate in the nest box as with no way for them to be broken down naturally before the next year’s summer visitors arrive.
The first swifts of 2021 arrived on the Cottenham fen edge patch in the latter half of April and more turned up over subsequent weeks with some locals reporting that the birds have taken up residence in nest boxes installed on their houses. It remains to be seen whether the visitors are inclined to nest in the new boxes this year, but the village has now offered new housing for the birds. It is their turn to take action.
UPDATE: 14 July 2021 – Simon Gillings spotted two cranes briefly at the Smithy Fen flooded field. Others have noted sandpipers and Ringed Plover raising chicks.
When it comes to local places to spot new and interesting birds, the first place you might try in this neck of the woods (as it were) are the various nature reserves we have within a few clicks. There are the RSPB reserves – Ouse Fen, Berry Fen, Fen Drayton, Fowlmere, Ouse Washes most of which I’ve mentioned on this site at least once in the last few years. Then there are the National Trust places like Anglesey Abbey and Wimpole Hall as well the likes of Wicken, Tubney, and Burwell Fen. Further afield there’s the Wetland Trust site at Welney and other fairly nearby RSPB reserves such as Lakenheath.
Turtle doves have arrived in Cottenham again for 2021
But, we also have a couple of very interesting birding sites in our village of Cottenham – Long Drove and Smithy Fen.
Long Drove stretches from the entrance at Beach Road all the way past the various farms, the back of the landfill site, several ponds, and on to the gravel works and then the Cambridge Gun Club. The drove itself is a public highway and most of those various spots are only observable from the road itself, nevertheless, there is often something to see in the fields, in the skies, and babbling about on the ponds.
Turnstone
Watch out for Common Buzzards and other raptors, including Kestrel and even Peregrine, small birds such as Linnets and Goldfinch, and plenty of gulls. For the gull aficionado (never seagull, by the way) there are often great flocks of mixed birds: Black-headed Gulls, Lesser Black-backed Gulls, Great Black-backed Gulls, Herring Gulls, Common Gulls (which are quite rare). Most winters and into the spring there are often some slightly less common gulls, such as Iceland, Caspian, and Yellow-legged gulls, which might even draw birders from wider afield. A couple of winters back there was a Hooded Crow (common in Scotland, but a rarity this far south).
Sanderling
Turning to Smithy Fen, however, the recent flooding of the paddocks at the bridge and the farmland adjacent to the Lode but beyond the travellers’ site has turned up a veritable mega list for local birdwatchers. None of the sightings are strictly ‘megas’, which is usually a term reserved for an incredibly rare bird. Nevertheless, several locals who send me sightings for my newsletter report have put together a list of birds one might not usually expect to see, but for those flooded paddocks and fields.
Avocet
Among them: Yellow Wagtail, Grey Wagtail, White Wagtail (European version of the British Pied Wagtail), Water Pipit, Meadow Pipit, Sedge Warbler, Stonechat, Wheatear, Wigeon, Shelduck, Garganey, Green Sandpiper, Golden Plover, Snipe, Jack Snipe, Dunlin, Redshank, Greenshank, Wood Sandpiper, Whimbrel, Bar-tailed Godwit, Black-tailed Godwit, Ringed Plover, Little Ringed Plover, Sanderling, Avocet, Ruff, and Common Tern. In the Fen Reeves Wood a Nightingale was reportedly heard recently, but it apparently stayed only a day or two. And, another for the gull aficionados, Kumlein’s Gull, which brought in quite a few birders from off the patch to see this rarity.
UPDATE: 2021-05-15 – Two Temminck’s Stints on the flooded field seen by local birder Brendan today. RSPB website describes this as a formerly breeding species with just 100 or so seen each year on migratory passage.
UPDATE: 2021-05-17 – Glossy Ibis has now been seen on that flooded field.
UPDATE: 20121-05-20 – Little Stint joins the one remaining Temminck’s
Yet to be noted are Common Sandpiper, Curlew, Turnstone, Spotted Redshank, Little Stint, Curlew Sandpiper…and then the rarities.
A Nuthatch (possibly the first in modern birding memory) turned up for a few days in the trees around All Saints Church and the gardens thereabouts. A couple of Turtle Doves are back as are Whitethroats, and Lesser Whitethroats along Church Lane.
Nuthatch – a first for Cottenham in modern birding memory
Speaking of Turtle Doves…
A community conservation officer for the Wildlife Trust for Cambridgeshire recently set-up a small project, following guidance from the RSPB Operation Turtle Dove project to provide supplementary feeding for Turtle Doves in South Cambridgeshire.
He contacted me in December 2020 having got wind of the half a dozen or so turtle doves we’d had in Cottenham in the summer.
Anyway, he was hoping to speak to local landowners on the patches where TDs had been seen, so I spoke to a couple of those I know. And, one of them was happy to discuss further. He met up a few weeks ago and seed has been scattered at the margin of the field and extra bags left with local residents to dispense. The idea as I understand it is actually to encourage pigeons to feed in places where TDs have been sighted and so give the TDs the confidence to feed there too and hopefully then to feel safe and so breed.
One TD was heard and seen in our village two weeks ago, a second one has joined it and both were seen feeding on the margin. I saw them on the wires today but they flew off towards the church after I’d done the initial photoshoot before I got closeups. This shot was taken from about 200 metres away.
Incidentally, if you’re a local and would like to be in on the local sightings as they happen I have a Google Group – Wild Fen Edge – which might be of interest, drop me a line on the sciencebase email address (db@) and we can discuss getting you in the Group.
I’m fairly sure I’d heard this relatively rare bird at RSPB Fowlmere several years ago but as a very, very amateur birder, I’d not seen one and certainly not seen one calling until this week. We took a trip to RSPB Titchwell on 2nd May 2021 and could hear one in the reed bed adjacent to the main footpath from the visitor centre, but didn’t catch a glimpse of the bird. A second visit in the week (5th May) and we could definitely hear the insect-like call of the bird and finally pinned it down to a patch of gorse and hawthorn not far from Patsy’s reedbed.
The Common Grasshopper Warbler is one of the grass warblers. (See What’s a Warbler, Anyway?). Given the name, one might assume that this bird dines on grasshoppers. But, that’s not the allusion of its name. Far from it. Rather the bird is so-called because its call is a constant monotonous trilling that sounds very much like the sound of a grasshopper. Here, have a listen to hear what I mean
The bird finds a safe perch, opens its bill and lets rip with its tuneless but rather delightful call. It’s quite difficult to pinpoint from exactly where the sound emanates, as is often the case with high-pitched bird calls. It’s almost as if the bird has some kind of ventriloquial skill. Nevertheless, we were lucky today and caught sight of it following an outburst as it weaved its way through spiny bushes to find its next perch.
There an estimated 16000 pairs in The British Isles and the bird is in the conservation red list as endangered. For comparison, there are 260,000 Sedge Warbler “territories”. The species can be seen across Europe from the west to Russia and Ukraine. It spends the northern winter in West Africa. The Locustella of the scientific name is the genus of which this species is the “type” naevia “translates” as spotted.
I’ve driven past Berry Fen, which lies betwixt the fenland villages of Earith and Bluntisham, dozens of times in my 30+ years in Cambridgeshire. Often when visiting friends out in the sticks but in more recent years, it’s usually been on a trip to the Needingworth side of RSPB Ouse Fen. Well, yesterday a fellow twitter user posted photos of an intriguing wader species that has turned up in the fens – Ruff, Tringa pugnax – so I thought I’d pay the site a visit, he kindly gave me the exact coordinate where he’d observed the birds.
Female Ruff, lacking the male’s “ruff”
There were two or three Ruff, several courting Lapwings, a Black-tailed Godwit, Redshank, Grey Heron, Little Egret, Moorhen, Mallard, Coot. To be heard in the trees and reeds flanking the flood: Willow Warbler, Cetti’s Warbler, Reed Warbler, Reed Bunting, Whitethroat etc. Oh and my first couple of Common Terns of the year.
Classic fenland sentinel, Grey Heron
Nice patch to visit on a sunny day. You can also take a detour from here to the larger lake at the north end of RSPB Ouse Fen or head for Brownshill Staunch and cross the Great River Ouse to get to the Reedbed Trail of that same reserve where you might catch a glimpse of Bearded Reedling.
As many regular visitors to the site will know periodically I poster “hyper local” information about wildlife on our patch, it’s mainly birds. This is often connected to the nature column I write for our village newsletter.
There has been, for many years, a mailing list associated with that column, which I took over from local birder Jasper Kay a few years back. The ad hoc mailing list has now morphed into the Wild Fen Edge Google Group. It’s a private group, you’re on our patch and wish to join, please drop me a line and I’ll add you.
One member of the group, Ian, has created a map of 24 very local spots where you might see any of dozens of bird species and other wildlife. There are various colloquial names for some of these places, but he’s used the official map name and pinned it to the map, so references to those places in our discussions can be standardised. A complete “tick” list for the patch will be forthcoming soon.
You can email a request to join the Group to WildFenEdge @GoogleGroups.com. There are no obligations to post or share sightings if you join, only obligation is to be civil in any correspondence and to not reveal precise locations of any listed or endangered species.
UPDATE: Sunny Sunday, so went to take some brighter photos, thankfully he was still there and calling loudly.
Over the last few weeks, the flooded fields around our village of Cottenham have brought in quite a few interesting birds we’d not commonly see here, although some are more frequent visitors than others.
We’ve had hundreds of Whooper Swans and a couple of Bewick’s Swans (for the first time in recent years), Red Shank, Oystercatcher*, Little Ringed Plover, Grey Plover, Golden Plover*, Green Plover* (Lapwing/Peewit), Shoveller Duck, Shelduck, Wigeon, Green Sandpiper*, Kumlein’s Gull, Avocet, Dunlin, Black-tailed Godwit, Snipe, Grey Wagtail*, Yellow Wagtail, White Wagtail, Pied Wagtail*, and various others. *Seen more than the others listed. Hen Harrier, Peregrine falcon, and Marsh Harrier have also been spotted, as has (away from our patch) White-tailed Eagle.
Today, well away from the flooded fields, a Nuthatch turned up at All Saints Church and was singly loudly variously from the yew tree at the main entrance, the trees at the vicarage, and the tall, budding oak behind the church.
As far as I am aware, this is the first sighting of a nuthatch in Cottenham for many, many years. Unless you know different, of course.
Thanks to Simon G, Brendan D, and Ian E who are the proper birders who first ticked and counted the various birds listed above.
Song frequency sits mainly between about 2.8 and 4 kHz, another bird calling at 7kHz towards the end of the video. A high-pass filter applied at about 1.3 kHz to mute wind and traffic noise.
Words, narration, and incidental music by David Bradley
Each winter, they arrive in their thousands. White, winter visitors flying in from the frozen north. Most will have come from their breeding grounds in Iceland. They navigation the east coast and sight land in North Norfolk. They will keep flying to their usual splashing grounds at Welney. The Whooper Swan.
The vast squadrons roost overnight on the waters, safe from foxes and other landlocked predators. When dawn breaks, they head for the fields. Where they will hoover up the green-top residues of beet and potato harvests. Before returning to their watery roosts each dusk.
In late 2020, the farmland around Welney and the Ouse Washes were floodier and floodier. The Whoopers were compelled to spread their wings and search farther afield. However, by January almost as soon as Fen Bridge Farm had harvested their sugarbeet. Several dozen arrived. The numbers have grown and grown.
Everyone in the village is asking everyone else about the honking and whooping. Is it geese? What are those birds? It’s amazing to see when you catch sight of them from the Lode or Les King Wood. By the end of January, almost 500 were on the flooded field there. Most of the greentops seem to have been purged from the land.They will most likely soon move on…to “pastures” new, although it’s worth noting that some are not even flying to roost these last two or three evenings, preferring to stay on the flooded farm at the edge of Cottenham.
We will have to wait and see whether they return to our Fen Edge Patch next winter. It will all depend on the flooding and the farming. Before the spring arrives though, this year’s birds will depart. Heading back to the frozen north for the next round in the circle of a Whooper’s life.
UPDATE: Numbers have been falling over the last few days. There were only four Whoopers on the frozen flood patch at the farm when we walked past today. They bobbed their heads and took flight as we walked past. Be interesting to know whether that’s the end of them on our fen edge patch for this year. It could well be…
