Bempton Gannets

It had been too long, in fact far too long since my last visit to Bempton Cliffs back in 2007. So I was now keen to return with some better camera kit to see what could be achieved at the UK's only mainland Gannet colony. A visit to Bempton is a great day out for the bird photographer and always an assault on all the senses in terms of sights, sounds and like all sea bird sites, smell.
The main photography at Bempton is for birds in flight but some portrait images are possible of birds precariously perched on the edges of the high vertical cliffs. Gannets are not the only species present as a whole range of sea birds use the site in large numbers including Fulmar, Kittwake, Guillemot, Razorbill and Puffins. All of these, except perhaps for the puffins, offer great photographic opportunities. However, for this blog post I will just restrict myself to some images of the majestic gannet. I must admit I have a great fondness for Gannets as they are such beautiful birds. 
Given that the cliff face is north-east facing then the best opportunities for flight photography come during the afternoons when there is a good westerly wind blowing. Under these conditions, the Gannets tend to 'hang' in the wind along the cliff edge. During the late afternoon we found a spot where a constant stream of Gannets were coming into land keeping the shutter finger very well exercised.

The birds were still busy collecting grass for nest building and it was a common sight to see a bird passing with beaks full of vegetation.
The is no question that Gannet are majestic and impressive birds with a wing span of around 2 metres. As graceful as they are in the air, they certainly are not always when coming in to land and can look quite comical at times as wings and feet spread in all directions to slow down their final approach. This is particularly the case for the younger less experienced birds.
At one location along the cliff where a number of gannets were landing it was nice to get some interactions between the birds including greeting each other and mating.
There is no privacy in the world of Gannets.
We finished off the day with a flurry of flight photos as the sun softened, the Gannets performing beautifully as they floated, twisted and turned in the wind blowing over the cliff top.
It was a very enjoyable session and a place I would wholly recommend for anyone wanting to photograph some sea birds. It is surprising how close the birds are on occasions and full frame images with a 300mm lens are perfectly possible if you chose the right place along the cliff top path. I hope to revisit the site soon and certainly will not be leaving it for half decade before my next visit!

Vole Patrol


I have been thinking about photographing water voles for a while. The main problem was where to start with numbers having suffered such a catastrophic decline. The key reasons for the decline, of this once common rodent, may be attributed to both habitat loss and fragmentation and the appearance of an 'alien' invader. The habitat requirements appear to be fairly straight forward being a slow flowing watercourse with a diverse abundance of aquatic and bank-side vegetation, banks that can be burrowed in to and minimal disturbance. However, the routine maintenance clearing of drainage channels to assist in the conveyance of flows and loss of river floodplains have all taken their toll on the vole. The other main factor has been the arrival and establishment of the American mink in the UK countryside through releases from fur farms. Some of these releases have been deliberately undertaken by anti-fur protesters concerned about animal rights. They obviously did not think about the rights of the native UK wildlife when they opened the cages to this highly efficient predators.

Fortunately there is a much greater awareness of water voles now which have been rightly afforded full protection status for both the animals and their habitat. A great deal of effort has gone into the encouraging the animals to return naturally through habitat management and assisted through re-introduction programmes together with the implementation of control measures on mink numbers.
Given the lack of local voles I decided to seek some help from a water vole expert, who kindly took me out to show me a couple of sites with a thriving population. She also helped me and hopefully my photography by providing a great deal of useful background information on their behaviour and how to look for signs of  their activity. Signs that previously I would not have seen such as small grazed patches of vegetation or plants stems cut with a characteristic 45 degree bite. So I would like to very much thank Kate for her invaluable help.
The site where I decided to concentrate my photography efforts is a short section of canal  where the usual concrete vole unfriendly banks have been replaced with a staked material. This allows the voles to chew hole in the material and access a buffer zone of abundant vegetation that separates the canal from the surrounding farmland.
From a photography perspective the site is slightly awkward as there are very few water level places for the voles to sit and only limited opening on the bank top where they have grazed down the vegetation on the opposite bank to which there is no access.
The photography of water voles is a waiting game and relying on them to appear at certain points where a clear view is possible. it appears to be characterised by brief flurries of activity between long periods of quiet. The start of the activity is often signalled by a rustling in the vegetation or a characteristic plop sound as one launches itself from the bank into the canal.
One bit of interesting behaviour I have already observed is how the voles fell small willows, like a mini beaver, to fall from the bank into the water so they can strip the stems free of leaves.
Of the various rodent species Water voles and Dormice are generally the species that have gain most popularity due to their threatened status but also they are visually very appealing animals. I also think that the cause of the water vole has no doubt been helped by fond memories of 'ratty' from the childhood stories of Wind in the Willows. They certainly have a charm went they are sat looking around and their popularity is also helped in that they often seem to be wearing a 'smile'. I have found that I much prefer to photograph the adults than the young which seem to have much more 'character'.
This is only the starting phase of this mini mission to photograph these delightful animals and I look forward to many more happy hours quietly sitting on the canal side watching the world go by and the place being lit up with the occasional appearance of a water vole.

The Joy of 'Groppers'

I seem to have a strange affinity with the Grasshopper Warbler which has allowed me over the last few years to build a good library of images. It strange as a bird photographer how you have great success with some species and seem to completely fail with others. Every bird photographer has a few 'bogey birds' for which they struggle to get images. For example, Dottrel that are relatively easy to photograph due to their very confiding nature I have never managed yet to put in front of the lens.

This is a highly skulking bird that loves to keep deep within low vegetation and a species which many have only heard but not seen. I think the key to my numerous prolonged encounters with these birds has been mainly due to timing. The window for photography is a narrow one and only seems to last two or three weeks from when the birds first arrive back from Africa and  until they have secured a mate for the breeding season. During this brief time the birds, that will have taken up residence in low clumps of brambles and scrub will frequently move up to the highest perch in the early morning to burst into their unusual insect like song allowing great opportunities for the photographer.

As insect grasshoppers are not usually singing at the time when these warblers are, if you hear the characteristic fast clicking sound in the mid-spring its a good chance it is one of these birds.

Homing in on the birds' locations can sometimes be difficult as during the song they rotate their heard to broadcast the sound giving it ventriloquist properties with it seemingly coming from somewhere else. It can be heard from a surprising long distance, as long as you and not too old to have had your high frequency hearing dulled. I think the song has some sort of hypnotic influence on me, as despite telling myself to concentrated on photographing other species, each time I hear it I find myself drawn in towards the bird. One thing I do know that is a hour or so in early morning light at close quarters to a 'Gropper', as they are known locally, is an unforgettable wildlife encounter.

Once a singing Grasshopper Warbler is located their photography is relatively straight forward as they are fairly unconcerned by your presence (as long as you do not move) and it is quite predictable where they are going to sing from. As with many warblers they have preferred song perches. Its really just a question of having some patience and waiting for the bird to occasionally pop up from the brambles on to one of its perches and start its 'reeling' song.
Given that I have so many Grasshopper Warbler images now, I have told myself that in future years I will do my best to ignore them and look for other species. Whether I will be able to stick to this remains to be seen and no doubt in future years on hearing the song I will be drawn back in gripped by 'Gropper' fever once again.

Tiny Wonders

You are more likely to hear the characteristic call of a Chiffchaff before you see one. These tiny leaf warblers, which are one of the first warbler migrants to arrive in the UK and for me herald in the start of spring, are normally spotted energetically flitting high through the leafless trees. The only time they stop moving is to go in to their characteristic two note song.
These birds certainly are not the most visually exciting bird being a rather drab brownish green with a feint yellowish eye stripe and streaking on the breast and very similar in appearance to a willow warbler. The colour does seem to vary slightly between individuals put the muted colour palette remains the same. Therefore from a photography point of view this is a bird may not be high on many people lists of target species. However, what they lack in colour they certainly make up for with a certain endearing nature to their 'character' and irrepressible energy and inquisitiveness which always makes the time in close proximity to one of these birds a pleasurable encounter.
Personally bird photography is not always about taking photos of the spectacular species, as I have always loved being in close proximity to a bird that many only see from a distance and being treated a brief insight in to their daily lives and habits. I believe such experiences make you a better wildlife photographer because by understanding behaviour, future close encounters become so much easier. In my opinion the greatest skill of  being a bird photographer is being able to get very close to your subject whilst it carries on with its normal behaviour.
I was recently told that the dark matted feathers that are often see above the beak when they first arrive and slightly evident in the photo above, results from the Chiffchaff feeding in Mediterranean olive groves on their migration up from Africa. I am not sure how true that is but it is certainly impressive that such a tiny bird that only weighs a few grams undertakes such long migrations.
One feature of their behaviour that certainly helps them on their journey is that their skills in catching aerial insects is on par with the best of the flycatchers. Their aerial manoeuvres in making sudden mid-air turns to snap up a fly with their flattened beak appears on occasions to defy the laws of physics.

The main challenge in terms of their photography is trying to find a bird that is a bit atypical and not too high up in a tree and using low bush or trees to forage and sing from. Like many warblers once they have established their territory they will often use the same set of song perches to sing from to attract a mate. Like the bird's appearance, the song is not the most exciting and sounds exactly like their name. However, it conveys the apparent unstoppable energy of the birds and often is sung relentlessly for very prolonged periods.
No doubt this will not be my last close encounter with Chiffchaff and I know the next will be a pleasurable and fascinating as the first.

Return of the Chats

A few years back Stonechat were a common sight, perched on the scrub and gorse of the coastal strip, along the north of the Wirral peninsula. These birds always raised a smile with their rusty round bodies giving them the appearance of a large bumble bee in flight as they dash between prominent perches.  I have also always really liked their characteristic call that sounds like two pebbles being tapped together.
The Stonechat have been nearly completely absent for the last couple of years locally, and I suspect the population of these very small birds were probably hit hard in the long harsh freezing winters of the last three years. The general rule is the smaller the animal the quicker it loses body heat due to its volume to surface area ratio which creates a need to consume more food in order to maintain itself and body heat. This is the reason that an animal such as the tiny shrew has such a voracious appetite. You can obviously see why a prolonged very cold winter could easily impact on these birds when energy demands are high and food becomes scarce under the freezing conditions.
So finding a pair of Stonechat had returned to the coastal area was very welcome after their prolonged absence. These birds are generally quite approachable which always helps with photography and on this occasion I concentrated my efforts just on the male as it was in such perfect condition. The main difficulty with photographing these birds is getting the photo exposure correct and retaining feather detail in the combination of the black head and bright white 'collar'. It is very easy to overexpose the white area.
With certain species of birds I tend to associate then with particular types of plants. For example a Grasshopper Warbler on brambles or Goldfinch on teasel. For Stonechat I always associate them with gorse as this is where they are most commonly perched in our local area. Despite having an extensive library of Stonechat images I have never managed to photograph them on flowering gorse and so was pleased to finally capture some images.
It also pays to sometimes switch to a shorter lens to give a wider angle of view to give a greater feel of the bird in its habitat. The difference between the image above and below is the result of switching from a 500mm lens to a 300mm lens.
These birds were only present for around a week and seem to have disappeared once again. It may be that the pair were just moving along the coast looking for suitable habitat to set up a breeding territory. However, the brief visit gives some hope that before long they may hopefully become once again a regular and welcoming sight along the local coastal strip as it has certainly been a poorer place for their absence.

Flighty Twitters


The most common view of a Linnet is of a small flock of about a dozen twittering small 'brown' birds in characteristic 'bouncing' flight across an area of grassland. There is quite a good population locally that use the habitat of the coastal rough grasslands and nest in clumps of gorse. However, the status of the national population is not great with the birds showing a 57% decline between 1970 and 2008 and therefore afforded a 'Red Status' of conservation importance.
From a photography point of view they are generally a difficult bird to get close enough to as you need to get past the many keen eyes of the flock. Therefore they tend to be a very flighty species often disappearing before you have got anywhere near them. The exception to this is very occasionally when you find a solitary bird in the Spring but it still takes a good deal of crawling and using any available cover to get close. This is how I have managed to photograph most of the birds in the past although crawling around through spike-laden gorse bushes in not recommended.
A couple of friends have been working hard to try and get Linnet feeding in one area through daily and liberal feeding. It has taken a lot of effort but finally the birds started using the area and free food supply regularly. This has probably helped these slim small finches through the lean times of late winter and early spring when seed availability is generally in short supply. Once you get birds feeding in an area like this, then the photography suddenly becomes much easier and you have much more control over the situation in terms of light direction, backgrounds and perches.

It is not until you are up close to these birds for a while that you realise that they are actually very beautiful and not just the plain brown bird that you thought. The black and white wing and tail feathers, chestnut coloured back and streaking across the breast all add up to a very striking bird.
The males in particular can be particularly attractive as they develop a reddish pink blush to the breast and forehead feathers. This red colouration shows quite a bit of variation and as you can see is not particularly well developed in the photograph above. However, in some birds the red gets stronger through the year as the light tips of the new feathers wear revealing the red breast below. There were two well coloured males visiting the feeding area and I was particularly keen to try and get some photographs of these birds.


The other point that a close encounter reveals is that their calls are much more complex than the twitter of the birds in flight and they have quite a repertoire of call and song. They were once a popular cage bird back in the times when such practices were legal and definitely sound a bit canary like in elements of their song.
Hopefully this has given you a bit more insight in to the Linnet and may give you a greater appreciation of them the next time you see a passing twittering flock of these wonderful little finches.

Easter 'Bunny'

To put the record straight, the original Easter Bunny was not supposed to be a rabbit but a hare. Hares are mostly commonly seen in the spring as the males energetically pursue the females. Their hormone driven pursuits have given rise to the phrase 'Mad as a March Hare'. If you have ever watched a male hare catch the scent of a female you will see how they become possessed and it is a common sight watching them sniff along the ground in pursuit during the Spring.
Hares were believed to lay eggs, which was probably a case of mistaken identity with Lapwing nests which share the same open field habitat. However, I suspect the giving of eggs at Easter has more to do with a symbol of fertility and renewal.

At this time of year hares will often sit up, as shown in the following photograph, presumably to give them a better view as the look out for females.
I love to photograph hares throughout the year. In fact my preference is actually to photograph them in late summer when the bird photography is poor and hares much more relaxed.  The only relaxed hare in the Spring is one that is taking the time to groom its fur. The one below was having a quiet moment.
Once the scent of a female is picked up a hare will follow it anywhere including across roads. Fortunately at the site where I photograph them traffic is virtually non-existent which is just as well as they will often pause mid-way across to try and get a better bearing on the direction of the scent trail. Obviously if there was traffic the consequences of this behaviour could be deadly.
Whatever they are doing they are wonderfully enigmatic animals and its worth taking some time to go out and look for them in the Spring which offers your best chance of seeing them. Unfortunately they are also a species which is under a great deal of pressure in the UK and one that is sadly in decline. However, on there side are a number of organisations such as the Hare Preservation Trust. Our countryside would be a much poorer place without them.
So I will finish this post with an image of Spring as a hare runs past a patch of daffodils and wish you all a happy and peaceful Easter break.
