Much to Mrs Sciencebase’s annoyance, I was awake at 6:40am today…her day off. I made a pot of tea, fed the dog, we drank the tea (Mrs Sciencebase and myself, not me and the dog), I then dressed and dashed off to RSPB Ouse Fen before the morning rush hour in the hoping of catching sight of a Bittern or two.

Well, I arrived to see lots of Linnets, Goldfinches, and Reed Buntings about. Skylarks cavorting with the Meadow Pipits, the sound of a couple of Chiffchaff and maybe four or five Cetti’s Warblers calling (I saw at least three of them), a possible Bearded Reedling “pew”, and the occasional boom of a male Bittern, from a couple of places, so perhaps two or more.

However, the big feature of the morning though was the five or six Marsh Harriers (Circus aeruginosus) that were doing their aerial courtship dance. The smaller, more patterned males with their darker heads chase the bigger females with their pale heads through the air and with each approach dive down to reed level. It’s a spectacular sight, be interesting to know how many were successful and whether numbers will rise again on this reserve.

 

Just looking for a nature reserve that I may have missed in our local area when I found a website that discusses the many and varied places you could visit:

The Water of Grafham (Grafham Water), for instance

Then there was Ouse is Washing (Ouse Washes)

Cherries Hinton Chalk Pits (that would be Cherry Hinton)

But, I’m definitely going to RSPB Ouse Fen again where:

The bitters are joined by a support group composed of marsh harpoon hovering above and pretty bearded breasts hanging on the reeds, like small trapeze artists.

Presumably, they’re talking about Bitterns, Marsh Harriers, and Bearded Tits, but I could be wrong…

The only explanation for such a ludicrously badly written web page I can think of is that they ran the copy through an automatic grammar checker and accepted all changes without reviewing them. However, the site looks like the content is originally from the Cambridge News, so maybe the awful edits were done to make it subtly different from the original material.

Indeed, the original Cambridge news article uses this phrase in talking about the arrival of spring:

Pop on a jumper and some sturdy shoes

the “archive” site has:

Put on a sweater and solid shoes

The  site also talks about “forests” whereas the original Cambridge News pages says “fenland”. As far as I know, there are no forests near Cambridge but plenty of local fenland; woods and spinneys yes, but not forests.

Oh and the Cambridge News talks of:

The bitterns are joined by a supporting cast of marsh harriers that soar overhead and charming bearded tits that cling to the reeds like little trapeze artists.

We heard an over-wintering Chiffchaff (at RSPB Titchwell on New Year’s Day this year, but today (18th March) I’ve just heard and seen the first one that has presumably migrated from Africa for the summer. It was calling with its plaintive, sound-of-the summer, onomatopoeic, metronomic and instantly recognisable ttt-tss-ttt-tss-ttt-tss-tss-tss call.

Snapped it quickly in Rampton Spinney as it was darting from tree to tree and calling in between. The Common Chiffchaff (Phylloscopus collybita) is a warbler and almost identical to the Willow Warbler (Phylloscopus trochilus), which I think I may have heard briefly on the opposite of this woodland at the beginning of my walk today. Very another sound-of-the-summer.

This is the call of the Chiffchaff. The first sound is the actual recording I made and it’s as you’d hear the bird in woodland or elsewhere. The bird usually repeats its chiff-chaff 11 to 14 times (in my original records, I’ve got 11 on one and 13 on a second sequence).

The second sound you hear in the video is that of the same bird’s call time stretched (slowed down) by about four times and then the frequency halved to take it down an octave in pitch. It reveals otherwise hidden detail in the bird’s call as well as allowing you to hear the echoing of the song from the trees of the woodland. The normal recording sounds cheery and chipper, the slowed down version rather more plaintive and melancholic, perhaps even eerie.

It had been a long time since we visited National Trust Dunwich Heath on the Suffolk coast. It’s a beautiful place and aside from a warden or two in the hut there was barely anyone around, we had the place to ourselves, at least for the first hour and a half of our walk.

Anyway, we parked up, layered up and set off on one of the mapped out circular walks hoping to catch a glimpse of a Dartford Warbler (Sylvia undata). Amazingly, there were a pair flitting about close to the start of the circuit, too quick to photograph, but not 100 metres up the trail, we could see at least three more, and we inched forward, not straying from the footpath, of course, and I got a few snapshots.

You can think of this UK resident species of warbler as really being a North African bird that stretched its range northwards at some time in the past, on to the Iberian Peninsula and up to the British Isles. It can be found in Wales, the South West and in Suffolk (there are thought to be 37 pairs on Dunwich Heath). You occasionally see them on the northern perimeter of neighbouring RSPB Minsmere (seen one once there) and further up the coast on the outskirts of Dunwich Village itself. We didn’t see any more after the initial lucky burst of five or so. But, we did see quite a few Goldcrests and Treecreepers further up the trail and the usual mix of woodland/garden birds, Long-tailed, Great, Blue Tits, Robins, Blackbirds etc.

In the notoriously cold winter of 1962/1963, so I am told, the cold killed off most of the UK’s Dartford Warblers; they are very sensitive to the cold. There were ten left and the current population, which amounts to some 3000 territories is quite an astonishing recovery.

Incidentally, the name of this bird has a rather uncomfortable etymology. Back in less enlightened times ornithologists generally studied new bird species by shooting them and then examining and reporting on them, rather than netting them, ringing them, and setting them free. Two specimens of what eventually became known as Sylvia undata were shot in April 1773 on Bexley Heath near Dartford in Kent. They were examined and described by Welsh naturalist Thomas Pennant.

As a footnote, when we got back to base to use the facilities before heading off to RSPB Minsmere (me in the car, Mrs Sciencebase on foot with the pooch), there were four moths showing well in the gents– three Dotted Border (Agriopis marginaria) and a (new to me) Yellow Horned (Achlya flavicornis), pictured below.

UPDATE: 5th November 2025, as I understand it from RSPB’s Rachel there are 85 Cranes on the Ouse Washes. 7th November, 83 reported on Welney.

UPDATE: 21st October 2023 68 now being reported at RSPB Ouse Washes

UPDATE: Species numbers seem to be on the up in East Anglia, with 60+ now as opposed to the 38 or so I first mentioned in the region. Spotted two at RSPB Ouse Fen (Earith) on the dogwalkers’ trail on 17th March 2022, having had a tipoff from Andy Hoy who had seen them on that patch several times for the preceding week or so.

Given this blog post’s title, if you didn’t know me better you might have thought I was going to discuss the interminable civil engineering and construction work that is going on in our vicinity – the construction of the new town of Northstowe and the widening of the A14 road.

But, no the topic is the avian Crane – specifically, the Common Crane (Grus grus). The bird whose scientific name simply means Crane crane, coming from the Latin for crane, funnily enough. It’s another tautonym where that means the name is doubled up to represent the archetype of the family.

Anyway, there are several dozen Common Cranes that spend their time flying between various sites and their surroundings around East Anglia – Namely: RSPB Lakenheath, WWT Welney, RSPB Nene Washes and RSPB Ouse Washes, RSPB Ouse Fen, RSPB Fen Drayton Lakes, Kingfisher’s Bridge Nature Reserve and nearby NT Wicken Fen. Presumably, once airborne, these large and graceful birds can survey a large area of the flatlands and head for whichever patch of wetland they fancy for any given period. I’ve seen them and photographed them from a distance at several of the spots mentioned above.

The largest number I’ve seen at one time is 37, I believe, but proper birders tell me that there are some 45 around and that there may well be at least one courting pair, which is good news for a species that was extirpated from the British Isles by the 17th Century. There is also a tiny breeding population in the Norfolk Broads and the bird was reintroduced to the Somerset levels in 2010.

Today, at least two were dithering about which direction to take over RSPB Ouse Fen (which nestles between the South Cambridgeshire villages of Needingworth, Bluntisham, and Over. It’s a converted gravel quarry site split in two by the River Great Ouse (a tautonym itself given that ouse simply means river, as does the word avon). A large part of this patch land is still active quarry, presumably providing gravel and sand for the aforementioned construction work.

I was walking the Reed Bed Trail, which is on the Over side of the river. Having seen 4-5 Marsh Harriers, a Snipe, and a Green Sandpiper, I was heading back to the car when a couple of birds almost as big as swans came into view, veering back and forth until they went out of sight. They were Common Cranes. Anyway, you might spot these large birds flying over any of the countless fens as they hop between feeding grounds and putative nesting sites.

Not to be confused with that far more common fenland icon, the Grey Heron (Ardea cinerea).

 

UPDATE: 22 Apr 2019, I wasn’t there but apparently, still Shorties at Burwell Fen.

Short-eared Owls (Asio flammeus) like to spend their winters where it’s slightly warmer than their native lands of Iceland, Scandinavia, and Russia. I say warmer, they migrate to northern, eastern, and parts of central southern England especially around the coast. But, they also seem to have favoured NT Burwell Fen this winter.

Got quite close to the Owl photographed above without spooking it, but there was a group of people up ahead who had an even better view when it landed right in front of them, but they decided to blunder ahead and get even closer than 20 metres for their photos, scaring the bird and ruining everybody else’s chance for a closeup.

There have been sightings of six or so Short-eared Owls over the last few weeks. I have seen at most two at one time there in the last few days, but possibly a third. Other photographers and birders there suggest only two remain. They will only be here for a few more days, maybe weeks, the weather and food source will perhaps dictate how much longer they will stay.

I haven’t yet been to see the Snipe (Gallinago gallinago) living on the edge of our village pond, but a visit to RSPB Fen Drayton today allowed us good views of a pair roosting and then feeding on the little islands right in front of the Coucher Hide there.

This species is incredibly well camouflaged in its normal environment. I spotted the first of two, Mrs Sciencebase the second. A fellow birder couldn’t quite home in on the places we’d seen them until the birds began to move to feed with their classic sewing machine bill action. Not to be confused with the Jack Snipe, which has shorter legs, a shorter bill, is a little smaller, and has more detailed and stronger markings but lacks the central yellow stripe on the crown of its head.

Here’s a shot from the hide of the more distant of the two Snipe we saw. This image is as it came out of the camera, uncropped, with no sharpening or processing, other than to resize for the web to reduce file load. Spot the Snipe!

The bird gives its name to the term sniper in reference to how British soldiers in the 18th Century used to hunt the species in India.

I made a start on a bird book, but there are so many around, it seemed like a futile effort, once I’d done a bit of due diligence and spoken to my publisher. My plan was originally for a nice, bright and glossy, book of full-colour plates, but they’re expensive to repro in print. The unique selling point (USP), aside from my photos, was to be discussion of the etymology of the different birds’ names, their recognised names, their folk names, and their scientific names. But, then I found and read Stephen Moss’s excellent book Mrs Moreau’s Warbler, which basically covered it.

So, here, in part-work form are the first few chapters from the sampler of what was to be Chasing Wild Geese – Spotting your first 100 birds. Apologies if you put your name down for a more positive update regarding a hardback, unless somebody wants to take up the option this book may never materialise. That said, my list is up to well over 100 birds now, so I could add new chapters over the coming months if there’s enough interest.
