Mating Mutes

The sun is shining a lot now and the snow has totally disappeared. Unlike two weekends ago which was bitterly cold and the lakes at Milton Country Park were partially iced over. It’s not always easy to see all the water birds but they had been coralled into smaller areas by the ice. Ducks abounded at the park with teal (Anas crecca, Dansk: krikand), gadwall (Anas strepera, Dansk: knarand), wigeon (Anas penelope, Dansk: pibeand) and tufted duck (Aythya fuligula, Dansk: troldand) in numbers, as well as the customary mallard (Anas platyrhynchos, Dansk: gråand). There were two highlights of the trip, a goldcrest was busy hunting in a bush just a few feet away and seemed undisturbed by our presence. Goldcrest (Regulus regulus, Dansk: fuglekonge) are beautiful little birds, they are our smallest breeding species, weighing 4-7 grams, and the northern populations migrate south in winter with Scandinavian individuals crossing the North Sea to overwinter in the UK.

I didn’t manage to get pictures of the goldcrest, which is a pity, but I did manage to get pictures of the second highlight, which was a pair of mute swans (Cygnus olor, Dansk: knopsvane). And if the goldcrest is our smallest breeder, the mute swan is one of the biggest (if  not thee biggest), weighing in at a hefty 10.5-12kg, and breeding is what this pair had in mind.

Mute swans pair for life and the courtship dance is delightful to watch, they gracefully circled each other, repeatedly intertwining their necks:

And the dance culminated in mating. The male climbed on board the female and grasped the back of her neck with his beak, the whole thing lasted just a few seconds, which was just as well for the lady as her head was held underwater and she actually disappeared from view.

And after mating they rose up, breast to breast out of the water and continued the necking dance:

Finally, they relaxed back into the water and finished the ritual by bobbing their heads towards each other, and apart from the mating moments the whole thing was very calm and sedate. I think mutes are simply regal, they are very big, powerful, animals and I can’t hink of any creature which is quite so pristine.

And shortly after mating the male climbed out of the water onto the ice for a post-coital stretch up to his full height and opened his wings, surrounded by a retinue of coot (Fulica atra, Dansk: blishøne) and gadwall. A fitting finale to this series of captivating natural events.

Robins and rails

I headed down to the RSPB reserve at Fowlmere south west of Cambridge early yesterday morning (Saturday 5th November, 2011) with my friend and fellow wildlife enthusiast, David, where I was hoping to catch sight of a merlin or a kingfisher or another water bird which I don’t see in my regular haunts. It was a murky, grey morning and the air was holding so much moisture it felt damp. Consequently, conditions for photography were challenging,

Probably due to the weather it wasn’t easy to see the resident birdlife. We heard a great spotted woodpecker (Dendrocopos major, Dansk: stor flagspætte) from the car park but once we entered the reserve it was really quiet, apart from the faint roar of the traffic on the A10 and the occasional jet heading into Stansted airport. But of birds, there was not too much evidence. We heard some redwing (Turdus iliacus, Dansk: vindrossel) and fieldfare (Turdus pilarus, Dansk: sjagger) as they passed overhead unseen, and as we got close to the Reedbed hide a robin (Dansk: rødhals) and a songthrush (Turdus philomelos, Dansk: sangdrossel) were lurking in the bushes near the entrance and a stoat scampered across the bottom of the steps into the hide. From inside the hide we could see 15-20 mallard (Anas platyrhynchos, Dansk: gråand) on the water, and perched on a fencepost on the opposite side of the water was a kingfisher (Alcedo atthis, Dansk: isfugl).

I like the segmentation in this picture and the physical delineation by the fence of the cut and uncut reedbeds. And of course, the tiny spark of blue and orange of the kingfisher sitting in the middle.

Also on the lake was a heron (Ardea cinerea, Dansk: fiskehejre) fishing in the shallows and half a dozen teal (Anas crecca, Dansk: krikand), and a muntjac deer wandered by. The kingfisher subsequently vacated and no further avian visitors appeared so we vacated too and made our way to the Drewer hide where we’d been told a water rail (Rallus aquaticus, Dansk: vandrikse) was busy feeding. And it didn’t let us down.

The water rail is from the same family as coots, gallinules (moorhens) and crakes and lives and feeds in and around shallow water predominantly on animals but also some plant material.

And whilst this charming waterbird was busy captivating my attention a robin was flitting between a nearby hawthorn bush and the reeds:

The robin seemed a tad out of place in the reeds, but a lovely dash of colour on a grey morning with its reflection in the pond


From the front it’s apparent that the water rail is a very slim bird facilitating easy movement between the stems in the reedbeds. I can’t remember the last time I saw one so it was a treat to see this one so close and it loitered for getting on for an hour, until after we left.

Bad birdwatching

The title of this post is unashamedly borrowed from the book “How to be a bad birdwatcher” by Simon Barnes (The Times sports writer and RSPB columnist), which I started reading today while I was waiting for my son to finish his swimming lesson. Having discovered what was meant by ‘bad birdwatching’ I can’t think of a better way to describe my fascination with birds and wildlife:

“…the first aim of being a bad birdwatcher: the calm delight of the utterly normal, and the rare and sudden delight of the utterly unexpected”. Genius.

I’ll write a review of the book when I’ve finished it, but please don’t hold your breath, reading a book is a fragmented and necessarily slow process these days.

Please forgive my rambling but there is a point to this. This morning I was planning to head to the lake beside the A14 between Histon and the northern edge of Cambridge to look for grebes, geese, ducks and cormorants. However, in the course of the last week I’ve seen green woodpecker on several occasions in and around the carpark at work on Cambridge Science Park. As I still don’t have a good photograph of a green woodpecker I reasoned an early morning stroll around work may enable me to put that straight. So that is where I headed.

Initially there were no woodpeckers to be seen but on a dull grey morning the trees and bushes were alive with birdsong:


Robin singing his heart out in an alder tree. He wasn’t alone, plentiful dunnock and wrens were doing the same

…as were numerous greenfinch, but this one clammed up as soon as I tried to photograph him. (Whilst taking this picture I was approached by a security man who said my camera looked like a shotgun. With the lens hood on at full zoom maybe a blunderbuss… but not a shotgun, surely!)

Cambridge Science Park is located on the northern edge of Cambridge bordered by the A14 to the north and the A10 to the east, it is around 1km in diameter and in keeping with the rest of this part of Cambridgeshire is as flat as a pancake. It was created in 1970 and some of the old trees and scrub remain between the buildings and the landscaping. These, along with small lakes and streams in drainage ditches form a good variety of habitat which is generally undisturbed.

I’ve worked on Cambridge Science Park for 15 years but I had no idea this  WWII pillbox was tucked away in the undergrowth until yesterday. (The pole in front of the dog has bat boxes at the top so I was very pleased to see the proactive approach to conservation).

Consequently there is alot of birdlife, from kestrels and sparrowhawks to water birds – ducks, coot, moorhen – and songbirds – greenfinch, goldfinch, great tit and I’ve seen goldcrest and lapwing on rare occasions. There are plentiful rabbit too and as a result it’s not uncommon to see foxes out the window hunting for a meal.

The Science Park was vibrant with birdsong during my walk and as time progressed the sun came out and it got warmer. I didn’t see any unusual species but the sheer numbers and volume of sound made for a very enjoyable walk.

Lots of birdlife to be seen, and all within a 500m radius of where I work. But I still hadn’t seen a green woodpecker. So I decided to head over to the lake within 500m of the Science Park where I know there are waterfowl including greylag geese… and green woodpeckers.

The lake didn’t disappoint. There were moorhen, mallard, greylag geese, great crested grebes – and even a single green woodpecker which was flushed up from the ground and disapperad into some distant and inaccessible trees.

Greylag goose

The greylag goose is the bulkiest of the Anser goose genus and is the species (Anser anser) from which domesticated geese originate. Studies of greylag geese led the zoologist Konrad Lorenz to rediscover the theory of imprinting – the phenomenon you are probably familiar with, of baby nidifugous birds (those which leave the nest at a very early age) imprinting on their parents, which can be a human being if that is the first creature they encounter after hatching.

Konrad Lorenz was an interesting man and a glance at his Wikipedia entry reveals he was an Austrian biological scientist, born in 1903. He graduated from Vienna University as a medic in 1928 and received his zoological doctorate in 1933. He joined the Nazi Party and indicated his support for their ‘racial hygeine‘ theories (one of the worst obscenities of the 20th century in my opinion), accepted a chair at the University of Konigsberg in 1940, joined the Wehrmacht as a medic and was shortly after captured by the Russians and eventually repatriated to Germany in 1948. He went on to study aspects of animal behaviour, later extrapolating these to apply to humans, and in 1973 he received the Nobel Prize for medicine for studies on social behaviour patterns.

Returning to natural history, there was a pair of great crested grebe on the lake which I were hoping were going to display:

But this time I was unlucky. When displaying, they swim away from each other then turn simultaneously and swim rapidly toward each other and when they meet they rear up in a necking dance before repeating the whole process. I haven’t yet been able to get photographs of this beautiful courtship ritual, but I’ll keep looking.

I said at the top of this post that there was a point to the ‘bad birdwatching’ reference. I set out yesterday specifically to try to photograph green woodpeckers which I think are spectacular. I only caught a fleeting glimpse of a woodpecker, and no pictures, but I had a lovely time looking and seeing all the other wildlife.

So I guess by Simon Barnes definition I’m a fairly shabby example of the birdwatching fraternity! But I’ll live with that.

 

 

 

 

Fen Drayton nature reserve

Before I tell you about my outing to Fen Drayton here’s a short update on the forest sell off. After denying they are backtracking, the Government has said they may reduce the amount of forest they are getting rid of. Plans to lose 15% of the 258,000 hectares of publicly owned forest are on hold whilst the government ‘re-examine the criteria‘ for the sale. I’m hoping this is government style smoke-and-mirror speak for ‘we’re deciding whether we should proceed at all‘. Time will tell. I think any reexamination is good news and maybe a sufficiently loud public outcry will force the powers that be to sit up and take notice of the vox populi on this issue, and maybe a few others too.

I didn’t manage a wildlife post last week, other events overtook me including the weather, which was blowing a gale at the weekend so I was struggling to see anything through binoculars and photography was completely out the question! So apologies for the omission. There were a few highlights from last weekend though: in a tree in the middle of a field behind Abbey Farm north of Histon I saw a pair of kestrels copulating – which is a fairly unusual sight but it’s good to know the local kestrel population should be increasing this year. Further round towards the Girton road was a big mixed flock of around 50 starling, a similar number of redwing and around 200 fieldfare feeding on the ground and as I was counting these a little egret passed over. I’d been told by a dog walker a couple of weeks ago there was one in that area but this was the first time I’d seen it for myself. Egrets are a comparatively recent addition to the fauna in the UK and they are slowly finding their way northwards in England. The first time I saw them was in the fish market in the middle of Victoria, the capital of the Seychelles, so they have very exotic associations for me and it’s great to see them so close to home.

I set off fairly early in the morning yesterday with my friend to head for Fen Drayton nature reserve which lies between Cambridge and St Ives. It’s a former gravel pit consisting of twelve lakes and ponds which is currently managed by the RSPB. There is a big area of water here interspersed with grassland, scrub woodland, some older more established trees and plenty of reedbeds. So it has a diverse range of habitats that are managed for wildlife and is therefore a good place to see birds.

Despite raining on the way up the A14, by the time we got to the reserve the rain had stopped, leaving complete cloud cover, so the light was very grey as you can see from the landscape shot above. Otherwise the conditions were good: mild, gentle breeze and the occasional, albeit brief, moment of sunshine.

The omens were good too when on the way to Fen Drayton we saw a hare running across a field, and on the approach to the reserve three bullfinch including at least two males were flitting along the hedge just in front of the car. When we were getting out of the car in the car park we could here a cetti’s warbler singing and three green woodpeckers rose up off the ground in quick succession just in front of us.

As we stopped to look at a group of tufted duck on the small pond north of Holywell Lake a jay which we had watched fly across the field appeared in some dead trees on an island in the pond and started stripping big chunks of bark from the tree, possibly looking for food it had stashed there previously. Jays are amazingly good at stashing and are aware that their fellow jays do the same and so will keep a look out to see if they are being watched. If they see another jay paying attention to their activities they will pretend to stashe and then fly off and hide the swag somewhere else.

Tufted duck are resident on lakes and we also get migrants visiting in the winter when they stop over on rivers and estuaries too. They’re omnivores and feed by diving to the bottom to sift food from the mud. I think they’re handsome birds especially when they turn their yellow eye to look at you.

Constant companions throughout our walk were chaffinch and great tit. They were present in numbers in almost every tree or bush I looked in.

There were a plethora of other small birds including blue tit, wren, dunnock, robin, goldfinch and long tailed tit. On a bright day it’s now a good time of year to look for and photograph birds because they are actively seeking mates and there are no leaves on the trees to conceal them.


One of a flock of around 7 long tailed tits whizzing through the trees – they’re fiendishly difficult to photograph like that so this is as good as it got!

There was almost a full house of the five common crows – jay, carrion crow, rook – but no jackdaw. There were quite a few magpies though:


This chap was bouncing around the car park

Coot abounded on all the lakes but the stars of the day were the ducks of which there were many species including our common or garden mallard, shoveller, tufted duck, gadwall and wigeon…


A single male wigeon on Oxholme Lake

… but the real star of the show was the goldeneye. There were displaying male goldeneye on Far Fen Lake but alas they were much too far away to get a photograph. They are also resident breeders with migrants arriving in the winter months too.

Mute swan were present on several of the lakes and a couple came over in flight too:


The A380 of the avian world…

And as with all good nature reserves the wildlife wasn’t solely ornithological. This beautiful little fungus was on a stem next to the path.


Dacrymyces chrysospermum – unfortunately I couldn’t find a common name for this resupinate fungus but its sumptuous colour against the green lichen on the tree stem is striking.

All in all Fen Drayton was a great venue for a Saturday morning wildlife adventure and I’ll be posting from here again before too long.
