Digiscoping: The Ruff Cut

Just a quick post this evening with some photos and video footage of the juvenile Ruff roaming the west quadrant of Wilstone reservoir today. Unfortunately, the Wood Sandpiper, which had been feeding alongside it, had legged it to the far bank of the reservoir moments before I arrived. The distant south quadrant was the Sandpiper Savoy today: 5 Green Sandpipers, 3 Common Sandpipers and the Wood Sandpiper were all resting and refuelling there.

So, I was using the Ruff as digiscoping practice (whilst also admiring its fresh, spangly, juvenile plumage, of course!). It was 60-80 metres away, feeding, preening and at times roosting. Conditions were overcast, grey and cool, with an occasional breeze. The results aren’t too bad considering the lack of light and distance involved. Once again, the white balance is off and I’ve not been able to correct it in post-processing. I need to test out other camera white balance settings and see if I can fix it at source. Photos and video were digiscoped (Swaro ATS80HD, x30W EP, Swaro DCA, Panasonic DMC-G3, 20mm f1.7).

Digiscoping Little Ringed Plovers …again!

Yesterday, I returned to the nesting Little Ringed Plovers and discovered they’d disappeared?!? No idea what happened, unfortunately. But, not to be deterred, I went in search of other bundles of feathers and found another nesting pair, at another site, which were well on the way to success. In fact, they had 4 fluffy little fledglings, although it took more than 2.5 hours observation, over 2 days, before all 4 revealed themselves.

This new family were an ideal subject on which to practice digiscoping, located on private ground and remaining flipping miles away. I’d estimate the group were mostly 60+ metres from me, although both adult birds halved that distance at various points for brief periods. The fledglings were scampering all over the place, often only 1 of the 4 was visible whilst the others were hidden in low growing vegetation.

I used the same set up as before (Swaro ATS80HD, DCB-A adapter, Panasonic DMC-G3, 20mm f1.7) but was also trying out a remote shutter release, to reduce vibration/movement as much as possible. I’d tried digiscoping on Friday afternoon but the heat haze was awful. This morning was overcast, fresh and calm so I thought I’d give it another go. I could have done with more light: it was difficult to get a workable shutter speed at a reasonable ISO. But, I came away with records of the family that I would not have been able to get with anything else I own. In the end, once I got the hang of taking photos with the set-up, I digiscoped some video footage and pulled a couple of stills from that. The white balance is off (which I don’t seem to be able to put right in post-processing) and the quality is poor in terms of sharpness but I was asking an awful lot of the system. Ultimately, I think the distances involved were probably pushing my luck, especially with such a small species. Anyway, all good practice and they were wonderful to watch!

How many chicks can you get under a brooding parent….?

EDIT: Update 03 June 2015


I visited the LRP family today and the juveniles are now able to fly and almost the same size as the adults. Now that they are less vulnerable, here’s a contextual shot taken from where I was standing and showing the location of the birds during the digiscoping session. I could barely see them with the naked eye…

Digiscoping Dinky Little Ringed Plovers

What about the birds, I hear you cry?! I seem to have spent the last week completely distracted and captivated by butterflies. Shame on me for allowing shiny new things to temporarily turn my fickle head. Yesterday, though, it was all about the birds. Little Ringed Plovers (Charadrius dubius) to be precise. They are a schedule 1 species which means it is an offence to cause disturbance at, on or near an active nest. Ordinarily, you need a license to photograph a schedule 1 species nest site but I was viewing from a public hide, at a warden run reserve, where no disturbance or intrusion was caused. I doubt anyone even slightly dodgy reads this blog but, just in case someone sinister should accidentally stumble across the threshold, I’ll be ultra careful and withhold the location.

As their name suggests, these migrant wading birds are Little, approximately 15cm long. Not much bigger than a Robin really. They winter in Africa and arrive in England and Wales in March, all set for breeding. At the end of June, early July they’re off again and head back to Africa. Until yesterday, I’d only ever managed distant record shots and certainly never glimpsed the eggs, like I did then, as they were devotedly brooded by both male and female in half hourly shifts.

This was my first outing with my “new to me” Swarovski ATS 80HD scope. Ever since I learnt about birding telescopes, some 6 years ago, I’ve wanted to get into serious digiscoping. Peering through rose-tinted spectacles, it’s a technique which seems to be the ideal way of watching and photographing birds. Disturbance is minimal, if not completely absent: the magnifications involved mean you rarely get anywhere near the threshold of tolerance in terms of proximity to the bird. And, it's even better if you’re hidden behind a conveniently placed bush or in a hide! I know it has its limitations and drawbacks but the idea of viewing & photographing fine detail, at a comfortable distance for both me and the bird, has always been very appealing. It is perhaps a string to add to one's bow rather than a catch-all photographic solution.

Anyway, to my first attempts at serious digiscoping. I don’t for one minute expect to get this right straight out of the box. In fact, I’m looking forward to the trial and error of it all and experimenting with different camera settings and adapters. But, to kick things off, I’m using the DCB-A adapter and 30x wide-angle eyepiece. The camera is a Panasonic DMC-G3 with the 20mm f1.7 lens. It was overcast, gloomy and even drizzled. From the hide, the birds were approximately 40 metres away. All images and video were digiscoped.

As I mentioned, the parent birds were brooding at least 2 or 3 eggs (I couldn’t quite see) and would change over every half hour or so. Lapwings occasionally bothered the sitting adult but for the most part nesting success looks possible.

Mrs LRP having a wriggle. You can just make out an egg at the base of her chest feathers.

Below: The head pattern of the male (left) and female (right). Essentially, the female has more brown mixed in with the black of the bands across the forehead (forecrown) and around the eye (from the bill, across the lores onto the ear coverts). The distinctive yellow eye-ring is slightly thinner too, making it seem less bright. With this pair, the male also has a pale pink base to his bill. The black forehead/forecrown band is lost completely in non-breeding plumage on both sexes.



The digiscoped video shows both the male and female brooding the eggs. First shift is the male. He clearly thought the nest was in need of a little housekeeping and also couldn’t quite decide which direction he wanted to face whilst brooding. After the switch over, the female also changed her mind about positioning before settling in for her stint.  I hope you’ll forgive the odd wobble or two. It’s impossible to keep the kit steady in a hide when people are coming/going/moving.




Overall, I was thrilled with the new scope and more than happy with these images/film clips as first attempts on a cloudy, grey day.
