Nailing a Few

FAVOURITE SUBJECTS AT CHESTER

24th & 28th August 2013

I suddenly realised that it was a long time since I had used my camera or stretched my legs properly, so I took time off from my chores on Saturday 24th to visit Chester Zoo again.
Unfortunately the light was rather grey and it was breezy, which could be my excuse for some disappointing photography. I could add that the zoo was very busy too, but I didn't spend much time in the busy areas. Actually I think that like a sportsman, I can be 'in good form' as a photographer but I also have bad days, when things don't quite work: after all taking a photograph involves hand-eye co-ordination, good body posture and pre-visualisation of an unpredictable situation, just like a batsman at the crease.
I spent a lot of time watching the black lion tamarins in their outdoor enclosure, I was pleased to see them looking well and they were very active, indeed rather too active for my convenience. I could see that they are more highly strung than the other species of lion tamarins, which is why they do not do as well in captivity. This was the best image that I managed with my 500 mm lens.

I did the spot a pygmy marmoset in the same enclosure, which was carrying a small infant. As I have written before, this species can be amazingly cryptic and the baby seemed to be asleep most of the time, so I could not get a photo where I could see the faces of both animals. Two friends posted a lovely photo on the ZooChat website, their secret weapon was their young baby, which happened to cry as they were watching the marmoset - which attracted the attention of the adult and the baby marmoset for a moment. I joked that I would have to think about putting a three-month old baby in my camera bag.
I did have one piece of luck, as I arrived in the Tsavo Aviary just as the keepers were feeding the birds with mealworms and locust hoppers. This attracted a brown-breasted barbet, which is one of the more secretive birds. I got a few nice shots.

This shot is the one that where I managed to nail it. Just about everything is right: I like the pose and the composition, the background is nice, the focus, exposure and colour are good and even the little things work - the branch hides the rings on the bird's legs and the profile of the beak shows the 'tooth' on the upper mandible which is characteristic of the larger barbets.
At least I had something to show from my day.

On Tuesday 23rd the Zoo announced that the baby Indian rhino had gone on show at just over 7 weeks old, although she would not be on view all day. As I was frustrated by my poor photos from Saturday and I had never seen a really young Indian rhino calf, I checked the weather forecast and decided to visit again on Wednesday. I prefer weekend visits as the M62 is usually very congested on weekday mornings, but I set off early and the delay was not as bad as I had feared.
I was delighted to see the little rhino 'Komala' with her mother 'Asha'. She is a sturdy little thing and already trying to eat grass: it was funny to watch her concentrating on chewing a couple of stalks while 'Asha' was tucking into great mouthfuls. The light was nice, but the positioning of the Asian Plains paddock and the viewing meant that I had to work contre-jour which is always more challenging than plain down sun snapshots. I have to remind myself to check my histogram display occasionally to make sure that the exposure is OK for some sample shots. Then I can reduce the contrast when I process my raw files with Capture NX2 to give more shadow detail, without losing the highlights.








The black lion tamarin enclosure gets some sunlight in the morning, but it filters through the trees which can give problems with patches of light and shade. I was pleased with this sequence.







The tamarins were quite vocal because they could hear (but not see) the golden-headed lion tamarins in the other Miniature Monkeys exhibit. The image below has the best Rembrandt lighting.






I also had the chance to work on the pygmy marmosets. I took quite a lot of images, but I think that I nailed two in decent light with both animals' faces visible and in focus. Although I was only shooting in landscape format (horizontal frame) when I looked at the first one I realised that when it was cropped it would also work in portrait format. I have posted both versions below, I think I prefer the vertical crop (but I might change my mind).

Mainly Miniature Monkeys

MORE FROM CHESTER ZOO

16th July 2013

I went back to Chester Zoo hoping to see the baby Indian rhino, but I had no luck with that.
I was also hoping to photograph the black lion tamarins - I had good views of them indoors on my first visit to the Miniature Monkeys exhibits, but the Eastern pygmy marmosets in the outdoor part of the same enclosure gave me marvellous photo opportunities.


The outdoor enclosures in Miniature Monkeys are completely open and thickly planted with shrubs and mature trees. These are carefully pruned so that the marmosets and tamarins cannot jump over the barriers which have smooth inner surfaces so that they cannot be climbed either. The pygmy marmosets are the smallest monkeys, they are cryptically coloured and they creep around the enclosure - quite different from the agility and dash of the other species of marmosets and tamarins. This makes them hard to see and they also spend a lot of time looking around as if they are checking for predators. Several years ago I watched a kestrel eating a mouse in an oak tree in Miniature Monkeys, it then flew across the path and inspected the floor of the other enclosure obviously looking for another rodent. This happened before the pygmy marmosets arrived, but I have no doubt that a kestrel would be capable of catching an unwary pygmy marmoset - so it is as well that this species is so cautious.
The individual above was sitting quietly in a patch of sunlight at the top of a shrub: a perfect pose for my 500 mm. A different one gave me a sequence as it crept along a dead branch, it then moved across to live branch and started to bite the bark to feed on the sap, which is part of the natural diet of marmosets. You can see more bite marks on this branch.

There was also plenty of action at the giant otter's pool. You can see that the two cubs are still significantly smaller than the adults when they are all out of the water; but in the water it's much harder to tell. I think this shot shows the two cubs in front of their mother 'Icana'. I love the water lilies in their pool, they look very attractive and the otters seem to like them too.

In Realm of the Red Ape, the light was very good in the aviary of the Timor sparrows and scissor-billed starlings, but this male splendid fruit dove hogged the spotlight. I used my 105mm macro lens for this image (and for the photos below too).












Back at Miniature Monkeys, I finally managed a nice shot of a black lion tamarin (or golden-rumped lion tamarin if you prefer). This pair are the only specimens in mainland UK and although I am glad to see them on show, I am also disappointed because they been kept off-show at Chester for a couple of years in the hope that privacy would let them breed. Their move to Miniature Monkeys is a sign that the zoo has virtually given up hope of success. I have written before about this species; it is the most sensitive and delicate of the three species of lion tamarins in zoos, although this pair seemed to have taken their move well. I am afraid that in few years time they may have disappeared from zoos in Britain and perhaps in Europe too.
I am told that these animals are now using the outdoor enclosure too, so I will try to take more photos of them soon.
Finally a photo of black rhino calf 'Embu' at two and a half weeks old, with his mother 'Zuri'. They were out in the paddock, but the grass was too long for decent photos of the little guy. I took this one as the keepers enticed 'Zuri' back into the yard with some pellets before taking them in for the night. The background is pretty horrible, but it shows how much the calf had grown since my previous visit.

Copyright and Creative Commons

A learning experience

As you may have noticed, I generally copyright all my images. My camera is set up to add copyright information to each one and I add a strapline to each photo that I post here and on Flickr (although under UK law this is not strictly necessary, if I understand the situation correctly).
I don't do this in the expectation of making money from them, because I do not have the property releases that most of my best images would need for commercial use on stock libraries and so on. Indeed I am happy to allow them to be used gratis for educational and charitable purposes, but I expect to be asked to give my permission. I was once tricked into allowing one of my photos to be used in a creationist publication and I am determined never to let this happen again.
However a few days ago I was contacted by someone who was editing the Wikipedia page on the black lion tamarin. He had seen a photo of this species that I had posted on Flickr a few years ago and he asked if I would remove the copyright on that image and then give it a Creative Commons licence so that he could add it to the page, following Wikipedia's policy. I wanted to help him; so after a little research, I replied that I was reluctant to change the designation of that image, but that I had two similar photos from the same sequence which I would let him use.
We agreed on this. I processed these images from my RAW files and changed the IPTC information embedded in these images before posting them on Flickr with an Attribution-ShareAlike Creative Commons licence (CC BY-SA).
I had not realised that there are several types of licence until I read the appropriate page of the Creative Commons website (http://creativecommons.org/licenses/). I quote the terms of this one (with apologies for the American English spelling)
This license lets others remix, tweak, and build upon your work even for commercial purposes, as long as they credit you and license their new creations under the identical terms.
I was prepared to do this as a one-off gesture to show my support for Wikipedia and for black lion tamarin conservation, but I would prefer to use a more restrictive licence which does not allow use for commercial purposes. However I do not plan to change my general rule of copyrighting my work.
So if you happen to need a photo of a black lion tamarin (also known as a golden-rumped lion tamarin) here is your chance. The photos were taken at Bristol Zoo in May 2009.

It's probably worth adding that there aren't many good photos of these animals around. Their close relatives, the golden lion tamarin and the golden-headed lion tamarin, are rather more attractive and are kept and bred in many zoos, although they are endangered in the wild: there have been successful reintroductions of captive-bred golden lions into reserves in Brazil. Unfortunately the black lion tamarin is much more sensitive and does not do nearly as well in captivity. Shortly after I took these photos in the Zona Brazil complex at Bristol, they moved the animals to an island exhibit and they were not on display at all on my most recent visits (I hope they are still alive). Chester used to have their pair on display (although most of their outdoor enclosure was shielded from view), but they built off-show enclosures near the animal hospital to provide secluded accommodation for this species and the equally endangered and difficult pied tamarin.

A last word on copyright.

If you value your copyright, be careful. Many years ago when I was teaching, my employers drew up new contracts which stated that they owned the copyright of all material created by each teacher. I doubt whether that clause would have been enforceable for material which was not related to teaching duties, even if the Pricncipal had wanted to do so, but nevertheless I insisted that my contract should specifically except any material which I had created for purposes not linked to my duties at the college.
For many years I posted my photos on my favourite discussion board, ZooChat (http://www.zoochat.com/) which acknowledged the photographers copyright. However I noticed a couple of months ago that this had been removed from the detailed captions of the photos, so I looked at the board's Terms of Use and noted that they had been changed to state that
