We've just returned from a brilliant trip to Wengen and the Jungfrau area in the Swiss Alps, to enjoy the early winter snow dump they've had this year. We spent most of our time careening down epic sledging runs, digging out snow caves, drinking hot chocolate, trying out slidy planks, and planning a new direct route up the Eiger nordwand. Paradise!

Back to Costa Rica...

CostaRica2017 (18 of 22).jpg

I spent a brilliant two weeks in January teaching our Costa Rica fieldcourse with a fantastic group of students. This year we split our time between a flooded La Selva and swamped Tirimbina on the Caribbean slope, the cloud forests around Monteverde, and the dry forest in the West. Highlights of the trip for me were catching Alston's singing mouse and a vampire bat (my first) and some really nice new herps. I very much look forward to returning next year.

Les Ecrins and Chamonix: mountains & marmots

We headed to the French Alps for a great fortnight in the mountains. We started with a week based in Vallouise in the Parc National des Ecrins, exploring the surrounding valleys and heading up to Ailefroide and the glacier blanc. It was fantastic to introduce the girls to mountain life!

We then moved north for a week based in St Gervais les Bains, revelling in the wonders of the Chamonix valley, the Mont Blanc massif and the celebratory atmosphere of the incredible Marathon du Mont Blanc.

Hyenas & Chocolate Cake

Things took a dark turn at Phoebe & Layla's second birthday, when the hyenas found Peppa & George.

Its been a wild year, watching the girls grow up - learning to walk, getting their first shoes and starting to grapple with animal sounds, language and each other. We've had some brilliant moments and seen some great things. Here are a few family moments from the past six months.

Costa Rica Fieldcourse...

We returned to Costa Rica to lead our third year undergraduate fieldcourse and had an incredible time. The journey started in the Caribbean lowlands, with a couple of days in La Selva biological station before moving round to Tirimbina's Robert Hunter field station. Highlights included eyelash pit viper, Honduran white bats, red eyed and red webbed leaf frogs, some fantastic spiders, wax-tailed cicadas, and cordiceps infested bullet ants. We then moved up to the Monteverde cloud forest for a few days, taking in three-wattled bellbirds, quetzals, long-tailed manakins, a host of wonderful inverts and some incredible bats, including the magnificent sword-nosed bat. For the last few days we moved down to the coast at Playa Grande and shifted our focus to marine conservation. Can't wait to return next year!

Kalahari Leopards

Returning to my field research site in the Kalahari desert, I took my SLR camera trap in the hope of catching something special. Working with my good friend Dylan Smith, who knows the area and its beasts like the back of his hand, we managed to get some beautiful shots of the female leopard that is gradually repopulating the reserve. She appeared a few years ago, perhaps having worked her way down from Bostwana. With a male who is also occasionally seen, she has now successfully reared at least two litters on the reserve. And from the looks of our images she may just have produced her third. Its fabulous to have these beautiful cats back on the land after so many years away.

Yellowstone & Grand Teton - Bears & Wolves


We spent a great week in the beautiful Grand Teton and Yellowstone National Parks in early September. It was still warm in the valleys and on the plains, with just a touch of autumn colour in the trees, but the high passes in the beartooth mountains had the feeling of coming winter. It was great to finally experience these stunning places, having enjoyed them from a distance time and time again in wilderness and mountain films.

We were hoping to catch up with quite a few of the region's mammals, while keeping the family sane and alive. With Phoebe & Layla now just starting to walk and trying out their first words, we tried to get out of the car and on to the trails as much as possible, and hoped that they'd settle in for good naps at peak mammal-driving times! After quite a bit time on the trails with our bear spray, Phoebe's tiny repertoire had extended to chanting "Hello bear! Hiya bear!".

We crossed paths with wolves on our last morning, with a great moment as a distant pair howled, gathering the pack.

In the end we caught up with grizzly bear, black bear, wolves, coyote, red fox, mountain goat, bighorn sheep, elk, moose, mule deer, bison, pronghorn and plenty of chipmunks and red squirrels. For some reason, despite repeatedly scouring apparently good areas, we missed most of the larger rodents, including the ground squirrels, marmots and pikas. Otter and beaver also elluded us, but we were never able to stay for long at the most promising spots at the right times of day, so that was no great surprise. We would also have loved to cross paths with American badger or one of the weasels, but it wasn't to be this time.

Logistics: we flew in to Jackson airport and hired a car for the week, spending our first and last nights in the Grand Teton area, heading up through Yellowstone to stay for the four nights in between near Cooke City, just outside the north-east entrance. While in Yellowstone we spent each early morning and evening in the Lamar valley area, where the chances of wolf are arguably highest, and headed deeper in to the park and on to the trails (bear spray at the ready!) in the time in between. As always, we had gathered together what information we could from the trip reports on, and found Max Waugh's Yellowstone wildlife guide and map quite handy, along with info from

Costa Rica - Puma by spotlight

After Costa Rica blew our minds in 2012, we thought it would make an ideal venue for a fieldcourse. Then the opportunity arose this year to put together exactly that, and so I headed back to the rainforest in July to check out a range of locations that we'll now be taking students to every January. The trip proved a cracker, with quite a few new mammal species for me, including the amazing Spix's disc winged bat, central American woolly opossum, tayra, and a life-experience find of puma while spotlighting on foot. The fieldcourse is going to be awesome.

I started my trip at Osa Conservation's beautiful Piro Research Centre on the Osa peninsula. Corcovado National Park had been the highlight of our previous trip (approaching from the west, via Drake bay) and so I was keen to return to the Osa, but this time to approach from the east and check out a potential fieldcourse basecamp. Piro proved an incredibly rich place, with some beautiful forest and great mammal, herp and bird life throughout its diverse habitats. Thanks in particular to Manuel Mendoza for showing me some of his favourite spots, and Golfo dulce poison frog (the Osa's awesome little endemic), and to Juan Carlos Cruz Díaz for all the camera trapping and mammal chats. All four primates (spider, howler, squirrel & capuchin monkeys) and agouti are easily seen in the forest surrounding Piro, and puma, tayra and ocelot are all regulars on their camera traps. With some great local knowledge I quickly got my SLR trap set up on a puma scrape, before exploring the area. Walks in the forest and a little spotlighting on the river yielded some great frogs, helmeted basilisk, armadillo and proboscis, nectar-feeding & common tent-making bats.

I then walked in to Corcovado National Park along the coast, from Carate to Sirena station. I didn't have time to stay on at Sirena, and so walked in and out on successive days (a 36km round trip). Some great sightings along the way included a dozing tapir, green & black and gulfo dulce poison frogs, a confiding Northern tamandua, a couple of slug-eater snakes, common tent-making and white-lined bats, howlers, capuchins, red brocket deer and a long-dead humpback whale! Wading the Rio Claro river was easier than it can be, as we hurried along to catch it before the rising tide swamped the river mouth. No sign of bull sharks or crocs. Nice.


The highlight of the Sirena station area was my first ever cordiceps fungus - sprouting out the back of a carpenter ant's head. My guide had been tracking its growth for the past two months! We had a great night, chatting on the porch and scanning for eyes, and I bumped into Nito - a naturalist guide who I'd met in the Amazon six years before. It was he who had convinced us, while we were busy watching night monkeys, to head to Costa Rica one day.

We set out for the Sirena river before dawn in the hope of catching the bull sharks. The tide was too high to access the river, but we had great views of striped owl, and super-fresh ocelot and tapir tracks, crisp in the sand after the night's rain.

Soon we were back on the return trail to Carate, putting our energy into hunting for puma. A female had been seen several times in the area and currently had cubs. We found fresh tracks and a troop of spider monkeys were going crazy above our heads, so we split up and scoured the undergrowth. But the noise eventually died down and we had a long way to go, so we moved on. It turned out that we were in the right place at just the wrong time; apparently she popped out on to the trail just two minutes behind us.

The heavens then opened in a spectacular way and we spent the next few hours marching in truly torrential rain. We passed soaked coatis, tamanduas, howlers and spider monkeys, but were warmed up by an awesome pair of tiny spix's disc-winged bats, hanging by their wing-suckers from the inside of a furled banana leaf. I was stoked - I'd been wanting to see them for years!

I returned to Piro for the night before heading out to Puerto Jimenez for my flight up to San Jose. With puma-hope still in my heart I went out to collect my camera trap, but nothing exciting had been through. A few weeks later Juan Carlos sent me these images from one of his nearby trail cameras, of a margay approaching my SLR trap (note one of my flashes in the centre of the image) to within a few inches of the trigger point before veering abruptly off the trail. Aaaargh! Next time.

I met up with good friend and co-leader on the fieldcourse Andy McGowan in San Jose and we headed up to La Selva Biological Station to work the trails and consider the options. It was great to be back - La Selva is a stunning place with an excellent trail system and great facilities. The whole region was experiencing severe flooding, so we had to travel in to the reserve by boat. We spent every waking hour on the trails, with some great birds (smart woodpeckers, several manakin species, snowy cotinga and a sun bittern on a nest), some nice herps, including green & black and strawberry poison frogs, and some cool mammals: three-toed sloth, nine-banded armadillo, greater sac-winged and proboscis bats and a stunning tayra - fantastic!

The highlight of the trip came on the second day. A puma had been seen briefly in the morning, so we headed out immediately and found tracks but no cat. We spent the entire afternoon and early evening exploring the area and returned after dark, spotlight in hand. The retreating flood waters had left a thin film of alluvium over the forest floor; ideal for tracking. And after an hour of spotlighting we picked up super-fresh tracks and as I rounded a bend by the main bridge she came right out in front of me, walked briefly down the path towards me and settled off the path in some bamboo scrub. It was electrifying - just the three of us in the dark. One of the most thrilling encounters I've had in the wild. We managed to watch her and share her with passing visitors and researchers for a good hour. Magic.

The next morning we moved on west to Tirimbina for the night, to take a good look at the Robert Hunter field station, explore the trail network and plan a range of field exercises. Thanks to our guide Willy for some great herp gen, and for being the first person I've met that has ever seen a yapok. Apparently most mammalogists look pretty miffed when they hear that he's seen one - Ha! Yapok (water oppossum) are incredible looking things, and one of my top five must-see mammals. It was seen in the stream near the field station, so you never know - we'll be back in January! Spotlighting in the rain around the arboretum at the main lodge yielded woolly opposum, Central American woolly opposum (my first) and nine-banded armadillo. Great place!

The next day we hit the road for the long drive up to Monteverde to plan the cloud forest part of the course. Highlights included the altitudinal gradient from the Monteverde Biological Station up to the continental divide, tickling a monster tarantula out of its burrow in Bajo del Tigre and finding long-tailed manakins in precisely the same place that we saw them three years ago. Watching three-wattled bell birds and resplendant quetzals in the same tree while drinking the best coffee I've ever had was also pretty killer; Monteverde coffee center - go there.

It was also great to hear that cats are making a comeback in the area, with puma, ocelot, jaguarundi, margay and even oncilla all gracing camera traps on the local trails. Gripped by the prospect I set up my SLR trap on a proven trail for our last couple of nights, but sadly nothing came through - but I'll be back with my trap every January, so something will eventually come of this!

The mammal highlights came from a couple of nights at the gate to the cloud forest reserve. Having sat at the hummingbird feeders for olingo on our last trip, I knew it was a great spot for nectar-feeding bats, so I took up some cold pizza (for me) and an IR trigger rig to see if I could get some pics. Among the many failures were a couple of gems that paid off for the battle with the rain. Note the pollen cap on the lower left bat below; clearly he'd already been busy with the flowers in the forest.

I had planned to spotlight the road after finishing with the bats, but a downpour rolled in. So I returned the next night and spotlit all the way down from the main gate to the first street light, hoping for kinkajou or olingo. In the end I had great views of both, standing in the silence on my own. The olingo responded well to a bit of squeaking, coming right down to eye level. A brilliant night.

We then headed to playa grande on the Pacific coast, with a view to ultimately using it as a venue for a marine conservation focus; critically endangered Pacific leatherbacks nest in this area at that time of year. So we spent our last couple of days checking out the mangroves and spotlighting the dry forest.

All in all, a brilliant trip. I can't wait to return, year on year, to share this place with our students.

Carpathian Mountains - Brown Bears & Ural Owl

The Carpathians had long been on our radar, with the promise of a step back in time, beautiful wild country, and some great natural history in and around Europe's largest tracts of old-growth forest. That they also hold Europe's largest populations of brown bear, wolf and lynx only added to the appeal. So in early June we packed up the twins, field guides and optics and headed to Romania with good friends to spend a week exploring the Piatra Craiului and Bucegi massifs.

Our first day in the field started well, with bear tracks at 05:30 and a distant brown bear through the scope soon afterwards, moving off the right-hand peak in the image above. The day ended with European beaver and yellow-bellied toad by a lowland river. While the mammals were fairly thin on the ground throughout, early mornings spent scanning from a peaceful vantage were a wonderful way to start the day.

European beaver have been reintroduced to a few sites in the area and are leaving some pretty obvious signs of their return to the forest! We had good views one evening of an adult and kit.


On our last day in the forest we took a long walk up the Dambovicioara valley that cuts in to the Piatra Craiului from the south, in the hope of finding a new vantage point for scanning the peaks to the west. The going was quite tough with the girls on our backs and the valley was deeper than we had expected, with thick beech forest and then pine rising steeply from the track edges and obscuring the high clearings that we were hoping to scan. But luck turned our way towards the top of the path when I stopped for a breather and my eyes drifted in to the forest landing square on the face of a Ural owl sitting quietly about 10m away. A striking and elusive bird, the picture does it no justice - as we were carrying the girls I had only my phone and the scope with just a shoulder to rest it on!

All in all we saw 11 mammal species between us: brown bear, stone marten, red fox, red deer, roe deer, alpine chamois, wild boar, forest dormouse, European beaver, hare, and one of the mouse-eared bats. A great place.
