In January and February of this year I took (yet) another birding trip to Colombia. Ken Edwards and I linked up with Daniel Uribe Restrepo for an extended foray that took us to Amazonia, the Llanos and the eastern foothills of the Andes. Rather than writing a 5,000 word tome on the whole trip I’m going to break it into parts, starting with the wonderful world of Mitú.

…is a small city in the Amazonia region. It’s in the deep eastern part of Colombia, near the border with Brazil, and thus about 250km beyond the end of the road network. To get there you can either fly from Bogotá with SATENA, or… not go to Mitú. But if you’re a birder you would want to go, for its remote location in the midst of a vast, trackless and undeveloped rain forest makes it one of the few viable places to access the wild and eccentric avian life of the Amazon basin.
So off we went aboard a shiny-new Embraer 170, which looked a bit out of place as it rolled into the grandly-named but rather rustic Aeropuerto Fabio Alberto León Bentley. After some tedious formalities where we had to provide our full particulars to both the tourism agency and the police, we checked into the hotel and headed off for a quick exploratory visit to the village of Urania.
Or at least that was the plan. But as soon as we hit outskirts of the town great birds started to pop up. A short roadside stop yielded ten species – not too big a number but six of them were life birds for me, including the highly desirable Paradise Jacamar, Cobalt-winged Parakeet, Yellow-browed Sparrow and Chestnut-bellied Seed-Finch. This was going to be good!
We managed to tear ourselves away and eventually reached Urania, but to get to the village we had to cross a covered bridge. And the bushes and trees on both sides of the bridge were alive with good birds: Moustached Antwren, Cherrie’s Antwren, White-browed Purpletuft, Swainson’s Flycatcher, Bronzy Jacamar and a host of others. One of my most wanted birds for the trip was the Swallow-winged Puffbird, and there were lots of them perched on telephone wires in full view. Hummingbirds zipped by while Yellow-headed Vultures (Lesser and Greater) soared overhead.
The upshot of this cornucopia of creatures is that we didn’t actually get to Urania. We spent almost two hours on the covered bridge without even reaching the halfway point, before the sun set and we had to head back to town. So Urania would have to wait for another day, but after collecting 27 lifers in an afternoon one was… contented. 😊
Day 2 – Cachivera
The Amazon rain forest is a vast area with a few tracks and trails radiating out from towns and villages. Birding the area involves walking these trails, accompanied by a member of the first nations that collectively own the land. We were very fortunate to have Miguel as our guide – or rather we were fortunate that Daniel knows who the best guides are and made sure that we got Miguel. Aside from having uncannily good hearing and an amazing ability to spot small, far-away birds, Miguel is a really pleasant person and very determined to ensure that every member of the group has a good look at all the birds.
The mission for Day 2 was to walk a long trail that leads into the terra firme forest. Terra firme refers to a relatively small percentage of the Amazon basin rain forest that does not experience seasonal flooding. As a result the trees are much taller than in seasonally-flooded (varzea) forest and there is greater biodiversity. More biodiversity translates into greater bird diversity, so we were hoping to spot some bird species that are endemic to the white sand terra firme forests around Mitú.
So off we went for a short drive at the crack of dawn, and as the sun rose we were walking through a village, across another bird-infested bridge and on into the forest.
The Birding Experience in Mitú
The program for the day, and for most of the days at Mitú, was to slowly walk along a track scanning for sounds and movement in the treetops and deep in the forest, and then try and zero in on any birds that we found. While not truly strenuous, it was hard work in birding terms. Bird sounds were everywhere but catching sight of the pesky beasts took time and patience. Most species were either high up in the canopy or skulking in dark tangles of scrub.
This made photography particularly challenging: I have lots of dodgy, highly-cropped photographs of far-away birds. Fortunately the Nikon D500 has outstanding capability in low light, but I had to master the changes needed to rapidly switch between bird-on-top-of-a tree-in-bright-tropical-sunlight and bird -creeping-along-the-dark-forest-floor.
Moreover, like every day we spent in the area, the sun was beating down, the daytime high was in the mid thirties, and the humidity felt like about 99%. There were also a reasonable number of pesky insects, but more about them later.
By the way lest this be interpreted as whining, I want to be clear that I was in Mitú at my own request, and we had a fabulous time. But for those might want to go birding in the remote Amazon I thought I would give you an idea of what to expect.
Back to Day 2
After a few hours, despite having seen some great birds we were starting to feel a mite fatigued. But then our fearless leader’s wisdom in telling us to bring a bathing suit was revealed. Cachivera translates as “pool”, but in local usage it refers rapids in a river or stream. But these particular rapids ended in a pleasant-looking pool, so in we went.
Lolling around in the cool water was refreshing indeed, and reinvigorated we pressed on. Shortly thereafter we came upon a mixed flock high up in the canopy and managed to clock a few highly desirable species including Flame-crested, Paradise, Fulvous-crested and Turquoise Tanagers.
In the end we covered about nine km in six and a half hours that morning before retreating to town for lunch. Later on, after a much-needed siesta, we went for a stroll down the old pipeline trail, adding the much-wanted Thrush-like Antpitta, Coraya Wren, Green-backed Trogon and Yellow-billed Jacamar to our tally.

Day 3 – A festival of Antcreatures
One of the reasons birders flock to Amazonia (groan!) is to gorge (metaphorically) on the huge variety of “antcreatures”: Antbirds, Antshrikes, and Antwrens. No, gentle reader, these birds don’t eat ants. But their favourite feeding strategy is to follow an army ant swarm, feasting on invertebrates as they try to flee the advancing ants.
These bird species are the kind of thing that hard-core birders really like: hard to find, hard to get a good look at, hard to tell apart and of course, hard to photograph. Antbirds and antshrikes are particularly cryptic: a range of small grey birds with semi-distinctive differences in the small white spots on their wings and back.
As we walked the new pipeline trail that morning we lucked upon an ant swarm with its accompanying suite of birds. Of course the ants don’t waltz down the middle of the road. They were in the forest and we needed to get ahead of them to catch the birds. This meant crossing the swarm.
I had somehow imagined army ants as large fearsome beasts, but the ones we saw that day looked like ordinary, medium-sized black ants. In vast numbers. And fast-moving too – if we stopped for even a moment we would find 40 or 50 ants racing up our legs with mayhem in mind. But it was worth the risk because when antbirds are near a swarm they are absolutely focused on feeding and you can get fairly good views without startling them.
So the ants generously provided us with a number of additions to the morning’s list, including Mouse-coloured Antshrike, and Dusky, Grey, Black-faced, White-cheeked, Chestnut-crested, Spot-backed and Scale-backed Antbirds. Or if you prefer, a bunch of LGJs (little grey jobs).
After lunch we returned to Urania/Mitusueño, and this time made it across the bridge and through the village. We piled up a good list in short order, starring Black-headed and Orange-cheeked Parrots, Yellow-tufted Woodpecker, a handful of flycatcher species and Azure-naped Jay. But the star bird was Blackish Nightjar. Nightjars and their kin are hard birds to see as they hide motionless during the day and only come out to hunt after dark. They breed in the area of Urania so we hoped to catch a bird or two flying over in the last moments before nightfall.
What I did not expect is to have one creep out of the bushes so close to us that I had to back away to get it in focus! We marched back to the pick-up point that evening with another 23 bird species added to my life list. A celebration was called for, and achieved after a thorough search of the town turned up a friendly ice cream vendor.
So that’s the story of our first three days in Mitú . Stay tuned for the next installment.
