Water birds at Milton Country Park

As I mentioned in my previous post, when I was at Milton country Park on a dragonfly hunt there were lots of birds about too, So between photographing the darters and hawkers I managed to capture some water birds:

Moorhen, Gallinula chloropus, preening on a log in a lake

Moorhens are common water birds seen on rivers and lakes, they can be secretive but are often seen out of the water on grassland. They are resident breeders and winter visitors in the UK with approximately a quarter of a million individuals. They are omnivores and are one of the few British birds which practice cooperative breeding where youngsters will assist in rearing subsequent broods. Their red beak and very long yellow legs and toes are distinctive and peculiar to the moorhen. The taxonomic name ‘Gallinula chloropus‘ translates as ‘little green footed hen’. For my international readership, the Danish name is ‘Grønbenet rørhøne‘ – according to the BTO. (If you actually call it something different or have a local name please let me know).


This coot (Fulica atra) was one of a group of moorhens and coots, including the moorhen above

I find coots amusing to watch as they have splendidly bad attitude and defend their patch against all comers, even members of their own species, and will aggressively charge other birds. They inhabit the same territories as moorhens and are also resident breeders and winter visitors. (In Danish – blishøne).

Great crested grebe with youngster

My favourite water bird (apart from the kingfisher, of course) is the great crested grebe (Podiceps cristatus). They can regularly be seen on open lakes and have been persecuted in the past because of their dense plumage which was used in place of fur. They have distinctive crested head plumage and an amazing courtship display. During the foot and mouth crisis in 2001 I watched a pair for a long time performing on a lake in Leicestershire – one of the few pieces of countryside where access wasn’t forbidden at the time. They would swim away from each other in a straight line for 20m or so and then turn and with beaks low on the water swim towards each other at high speed, raising up when they reached each other forming their necks into a heart shape. All terribly romantic! It’s a beautiful display and one of these days I’ll hopefully see it when I’ve got my camera handy. (By the way, in Danish these are ‘toppet lappedykker‘). Great crested grebe are also resident breeders and winter visitors but the numbers are much less than moorhen or coot, with 8000 adults here in the summer. Despite the lesser abundance their conservation status is green.

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.

…and one of a flock of long tailed tit

…and a moorhen

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.

 

 

 

 

Early morning duck walk 22/01/2011

Before I sally forth on my intended theme for this post, and continuing the astronomical precedent from my earlier post where I included a picture of the recent partial solar eclipse, I want to share a picture of the moon I took last week. At this time of year opportunities for wildlife photography in the evenings are severely limited. But on Tuesday and Wednesday (18th and  19th January) the moon looked spectacular early in the evening when it was low in the eastern sky,  and also very early in the morning, around dawn, when it was low in the western sky. So on Tuesday I rushed home from work, grabbed my camera and headed out the door with the dog in tow to try some lunar photography. I think the moon is an amazing thing and I can’t resist the opportunity to photograph it, and this is what I got:

Full moon low in the eastern sky 180111
Full moon low in the eastern sky around 6pm on 18th January, 2011 (f5.6, 1/800, ISO 800, 300mm)

After my lunar digression, and as alluded to in my post ‘Avian East Anglia’ I have been out taking a look at the bird life at Milton Country Park. I set off with my friend just after 8am on a very cold grey Saturday morning, which became progressively colder, greyer and rainy as time went by. Consequently I was less than hopeful of seeing much in the way of wildlife.

My fears of a fruitless walk at the Country Park were unfounded. As we entered the park a great spotted woodpecker (Dendrocopos major) was making plenty of noise high in a tree and during the walk we saw two and heard at least two others. I don’t usually use a spotting scope but my friend, David, has one and it really does enable some terrific close up views of  distant creatures. We viewed a great spotted woodpecker at the top of a tall tree a good 100m away and the scope brought it right up close. I may add one to my next Christmas list.

A distant great spotted woodpecker – if only I could digiscope! This one wasn’t taken on Saturday… but it was at Milton Country Park

A cock bullfinch (Pyrrhula pyrrhula) was busy feeding in some bushes at the edge of a lake and plenty of blue tits (Cyanistes caerulius) and great tits (Parus major) were to be seen. A brood of six last years mute swan cygnets (Cygnus olor) were communing  in a quiet corner of a lake:

One of six mute swan cygnets

And a pair of adult mute swans were on the slipway into an adjacent lake. A flock of mixed gulls consisting predominantly of black headed gulls (Larus ridibundus) with a single common gull (Larus canus) in their midst shared a flooded field on the edge of the Park with a flock of 57 lapwing. The lapwing would take to the air periodically and fly circuits round the Park before settling down again and each time they rose there seemed to be more of them, but a final count on the ground came to 57. I was pleased to see this number as I rarely see flocks of lapwing greater than 20  individuals.

Coot (Fulica atra), cormorant (Phalacrocorax carbo), a moorhen (Gallinula chloropus) and a lone kingfisher (Alcedo atthis) made appearances but the stars of the day were the various duck species. I like ducks and it’s always good to see more than just mallard:

Note the prominent tuft and the yellow eye of the tufted duck (Aythya fuligula) above. It was tricky to get good quality images due to the low light of the murky early morning. I opened up my lens (Nikon 70-300mm VR2 zoom) to f5.6 and was using a shutter speed of 1/80s at 300mm zoom. The ISO was set to 800 to cope with the light hence the slightly grainy look.

A flock of approximately 20-30 shoveler (Anas clypeata) were feeding on the same lake as the tufted duck:




Small group of shoveler – see the splendid beak of the male in the background (top) and in the foreground (lower)

Shoveler diet consists of small insects, molluscs, crustaceans, seeds etc. which they filter from the water with huge spatulate beaks by sweeping the beak from side to side with their whole head underwater whilst swimming round in tight circles. They come up for air only very briefly which meant I had to take quite a few pictures before getting one with the beak visible. Beatiful birds, I like these.

Several small groups of wigeon (Anas penelope) and gadwall (Anas strepera) mingled with the other water birds such as the numerous coot, gulls and cormorant.

By the end of our walk I was frozen but it was well worth braving the cold to see such a diverse range of birdlife. I shall return there on a sunny morning to try and get some less grainy photographs!
