Bearly Believable – Birding Bolivia (3 Viewers)

Loving the butterflies even if they’re impossible to get to species a lot of the time
The only field guide I have, or can find, is Butterflies of South America by D'Abrera which is of very limited use so I have mainly been relying on iNaturalist and Googling any suggestions and similar species so any suggestions/corrections much appreciated.
 
There’s a huge butterfly list isn’t there and the main online site I’ve seen is largely commenting on how incomplete the information is. It’s just nice to see a few of them as frustrating as the lack of info must be if you’re the one whose actually seen them
 
I agree all the Butterfly ID's, even if vague, are cool to see. I have well over 1000 days in the field in S America and know next to nothing about the butterflies, sadly :( I do have one book for Ecuador and have used it to try to get to the genus but I really have never dedicated enough time or developed any field skill with thim.

And not to sound like a broken record or be a pain in your guys collective butts, but the bird labeled Slaty-capped Flycatcher looks like a Myiarchus to me. I don't know what's expected there but likely the Dusky-capped, Short-crested, Swainson's, Brown-crested are possible? The (apparent) lack of rufous visible on the underside of the tail would be the biggest clue to help.

Just to be quite clear, what we value is accuracy so anybody can suggest replacement identifications at any time. The labels on the photos are (usually) the best we could do in the field with the Birds of Bolivia: sometimes we had access to the internet to check additional photos.

Reasons/explanations would be appreciated however.

In this particular case we did look at the Myiarchus flycatchers but Dusky-capped has too dark a cap coming below the eye, Brown-crested lacks the broad white tips to the median coverts, Swainson's has a pale lower mandible and Short-crested (like the others) lacks a distinct and pure white throat. But the illustrator may not be completely accurate of course.... I'll look again at internet photos.

For me it looks like a Myiarchus due to: head shape and bill immediately structurally suggest it. Overall coloration with a generally unmarked face/cheek, not strongly marked wing, dark eye. Tail length fits. Also, the photos are suggestive of a bird that was happy to perch somewhat in the open and vertically which is worth quite a bit jizz-wise among the myriad flycatchers.

The lack of visible crescent "ear patch," lack of any trace of a paler eye, and the lack of the "string of dots" wing bars on the upper wing coverts (which is quite distinctive for Slaty-capped) make it, to me, not look like that species.

As for which Myiarchus it would be, I'd want to look at eBird frequencies for the hotspot and look at both art / descriptions and Bolivia specific photos (taking care that many photos online of Myiarchus are mis-ID'd, and that there is substantial regional variation in each species). I've not got a ton of time to dig into it now (I generally like these kinds of ID challenges) but for starters I'd look at the eBird hotspot bar-chart: https://ebird.org/barchart?r=L831297 (Slaty-capped isn't recorded there it seems, assuming this was still the SC Botanic Gardens), then dig into ID criteria.

Anyways one of my friends is in Santa Cruz now waiting for us and the rest of us are off tomorrow. Exciting stuff for me, it feels like it's been too long for me since I was last birding in South America.

I'll try to update the butterflies as I get more information.

I probably only have about 150 days in the field in South America and that has been spread fairly evenly over almost 40 years. I've never really got my head around the birds in the way that I have in parts of Asia and Africa, and also I was too tight to splash out on the ridiculous cost of buying Bolivian field guide in the UK, so more than happy to take advice from someone with a far greater knowledge of the birds.

I agree it's a Myiarchus.

FWIW, we had both Short-crested and Brown-crested around Santa Cruz last month (but neither in the Botanic Gardens). If I had to guess, I'd say Short-crested.
 
Back in the more formal gardens we found not only the still elusive Purplish Jays but also bangingly weird-looking Plush-crested Jays with their luminous-appearing contrasting blue eyebrows over bold bright yellow eyes. These also had a fairly long flight distance despite foraging around a picnic area and I felt there was more to do. I was however distracted by a finch with the same array of colours as the Red-capped we’d had in the wet: this one however had a tall crest and paler grey back and was obviously Red-crested Cardinal – tick! It preferred feeding in the shade – the heat of the day made me agree and I was seeking out shadows to lurk in – but I got a shot of sorts and moved on as Steve was calling me to a Yellow-rumped Cacique (tick again). I struggled to get a clean shot of this, which teased from among orange blooms on a splendidly flowering tree. Perfectly adequate bins views but just not quite there with the camera.

Before long we were off around the reserve again to make the most of our time. Steve found monkeys in a tree near the nursery and compost heaps: a family group of Black-and-Gold Howler Monkeys was enjoying the afternoon sun and for once we had good light from behind us. The adult female promptly decided to evacuate its bowels and judging from the amount descending must have just about turned herself inside out. I have no pictures of that…. I do have some of the adult with a very small infant as well as a yearling or older juvenile. We didn’t see a male on this occasion: it’s the adult males that are black while females and young are a goldy-blonde more likely to be seen on a bad hairpiece than a genuine head of hair.

Eventually they retreated into shade and we moved on, once again down the central track occasionally investigating side trails, some of which narrowed and petered out into impenetrable scrub. Occasionally we found birds feeding through the scrub, many of which gave too brief or occluded views for identification but including a pair of Bolivian Slaty Ant-shrikes and another honking-billed Buff-throated Woodcreeper: then Steve spotted a male Blue-crowned Trogon sitting in the open and after a short period of that desperate inability to get on an obvious bird (being “bird blind” was a birder’s description of the affliction that I liked) I spotted it and with relief got pictures of a fabulous bird. It did seem however that we went long periods without seeing anything at all, prompting a sarcastic remark from Steve that “the thing about tropical birding is they way you are overwhelmed with the avalanche of birds all the time” – which became something of a running gag for the remainder of the trip.

At some point in the day a Brown Agouti crossed our paths but it was a brief view in scrub and I don’t remember it clearly enough to place it in sequence with everything else. Sometimes the notebook takes second place and things get remembered while calling the log (where you at least have a systematic list to check against albeit ours wasn’t the full 1440 species Bolivia list – I’d edited that down to something under 600 on the basis of the field guide’s distribution maps, recognizing there would be write-ins to add back) so they aren’t missed, just hard to time accurately in some cases. Incidentally it is not helpful to have maps in a guide on different scales, showing different areas, rather than a standard country map easy to compare between species. I do recognize there are some advantages for restricted range species….

Returning eventually towards the formal gardens we were surprised by a sudden eruption of quite large bats from a tree roost ahead of us. There wasn’t time to either get good views or photos: they just piled past us and veered off mostly in a flock into the woods. A couple that seemed to have landed proved impossible to locate and may have gone straight through the trees they had made for. They were over a foot in wingspan and quite broad-winged, appearing generally to be light grey-brown: but we got no details.

Spotting an icecream seller’s tricycle Steve decided to enjoy a choc ice but I bottled out of buying from such a seller at the end of a long hot day, which was probably over-prudent. I admit to feeling jealous not very long afterwards.

Crossing the dual carriageway without incident we missed one bus while I withdrew more Bolivianos from an ATM at a filling station (still diesel queues there) but caught one soon after. At one point I thought the machine wasn’t going to give my card back but I think it was just unfamiliarity with the particular equipment and all was well after a few moments panic.

The trip back into the city was uneventful except for a crutch-wielding individual who boarded and began a harangue/begging speech/request for investment in his crutch factory and passed up and down being resolutely ignored by all, before hopping lightly off, forgetting to make use of said crutches in his dismount. He remembered before we left that stop (btw he hadn’t paid his passage and the driver didn’t pressure him for the fare) and leaned operatically heavily upon them. Yeah, right.

For dinner I reprised the pulled duck in rice with what I now recognized as deep-fried plantains at the El al Jibe.

11 August: You crazy – the fall will probably kill you!

First thing in the morning a family group of five Sayaca Tanagers was hopping about on the spaghetti of wiring on the powerline post opposite the window of Room 107. I didn’t want to photograph them in such a setting but watched with interest until they flew off to a more likely foraging area.

Breakfast was sophisticated and for once didn’t involve los huevos: ham and cheese toasties!

We just had time to check out before our driver to the Refugio appeared with his 4WD. It was to be good roads all the way to the Refugio entrance track so although the car was not spacious it was an easy trip: every filling station we passed in or out of the city had trucks, tractors and diesel cars queuing for fuel.

Ruben Beltran, our driver up to the Refugio, had the resort’s logo on his car so was clearly not just a taxi driver but a Refugio employee or contractor. He drove us up the steep 4WD track to the mirador at the top of the ridge (Steve began to say something as we proceeded up the first long straight but I told him at once not to say anything and he obliged, for which I was grateful as I clamped my jaw on my nervousness even when the wheels got a little squirrelly on a damp patch). Then we changed to Refugio’s Mitsubishi 4WD truck to go down the steeper track to the Refugio with lots of tight hairpins – scary! Happily the driver undertook his three-point turn backing towards the several hundred foot drop before inviting us to board, for which I was extremely grateful. However, he was then going to slide the back bench seat forward to make room behind it for all the bags, inevitably making me sit just behind him – I told him I was going to sit right in the back where I couldn’t see out very well! I was not helped by Steve, judging his gagging order over, helpfully warning me not to look at the road…. Updated by our taxi driver’s translation the Refugio man shrugged and left the seat where it was, heaving a suitcase in next to where I would sit. Much appreciated, gracias.

Actually I continued to find that concentrating on the surface of the track just ahead of the vehicle controlled my irrational fear with perhaps the exception of going into a few hairpins where the chap had to swing wide towards the edge to get round smoothly – oh Lord…..! After only about twenty minutes we were on the flat floor of the valley and I was hoping there would be no rain before we left – I had no ambition to try that track in the wet.

We disembarked and looked around at one of the most stunning views I’ve ever seen from a hotel. We were in a complete bowl surrounded by wooded slopes leading up to huge sandstone cliffs (not sure where the “volcanes” aspect comes in) on mostly rounded peaks, some of which were wide and flat enough to have grasses, scrub or woodland on their summit plateaux. The sky was brilliant blue and the sun shone in almost friendly fashion.

Our en suite room was on the corner of a single-storey block with wide shallow roof projecting far enough beyond the walls for a tiled veranda with a low retaining wall from which rustic wooden columns supported the eaves. Very Spanish New World architecture. Inside was not as large as Room 107 but it had three beds, making one of them a natural suitcase shelf for those intending to live out of the case (for less than a week, that definitely means me.) Part of the bathroom floor was wet and as we came in and out over the afternoon we noticed this was spreading: there was a leak somewhere below the floor tiles. But was it from the clean or foul water system? Perhaps our room had been empty and untended for a couple of days because the staff took the news without surprise, despatched someone to immediately dry it up and thereafter it didn’t really recur.

The local long-haired domestic cat checked out the new arrivals and ignored our suggestion that it should go somewhere else. We soon afterwards found it playing with a lizard that was skidding about on the tiled outdoor area and no doubt annoyed it by shooing it away and removing the lizard to a safer place out on the lawn. Despite this blatant interference with its habits the cat seemed to take the long term view that any company was better than none and continued to seek us out as well as accompanying us on any trips from accommodation to the dining area and back. While looking around on our own we found a Lineated Woodpecker on a tree growing out of the open lawn, not part of the surrounding forest, not far from our room.

A little later Steve, outside while I was rearranging kit indoors, called that he had a King Vulture and I got out just in time to get sufficient on it for a tick. I was definitely hoping for a return match later in the week though, with this one of the birds I especially wanted a decent view of due to its wonderful head colours.

We added Military Macaws – Steve’s key species at this location, though not his only target – flying across the face of one of the great faces of red rock looming over us, as well as Black-billed and Rufous-bellied Thrushes bouncing around the short turf along with the now familiar Creamy-bellied.

We were introduced to Rocky, our guide for the week. He was a lean, wiry bloke a bit shorter than me (and I’m not tall) but possessed of great energy and in combination with his phone and its apps, more than capable of finding us the birds of the area. However, his tendency to reach a known stakeout and immediately resort to playback to attract the bird definitely wasn’t Steve’s thing and to be honest it’s not how I bird normally either: I’d rather find as much as possible by human senses and if something needs a little encouragement then perhaps give it a burst. Still, there’s no denying that the technique works and with limited time in thick forest with not great light, it was generally effective. Where individuals didn’t respond you did have to suspect they were hearing the recordings and going “Yeah, heard it all before, that’s track No. 3 from Xeno canto”!

I'm already putting these pictures up on Flickr and every time a big woodpecker gets uploaded somebody from a group called "Ivory-billed Woodpecker and other Dryocopus and Campephilus Woodpeckers" asks me to add my picture to it. Normally I approve such invitations but I'm not endorsing any group that seems to suggest the extinct IBWO is still with us. So, no no no!

Anyway, after lunch Rocky walked us round the lawns of the Refugio before leading us towards the entrance track. He darted off left just as we reached it, beckoning us to follow, and promptly called in an Amazonian Motmot (tick) – one of those classic South American species that is a mixture of neutral camouflage colours and explosively bright blues and greens making for species recognition in the subdued forest light. I had a bit of a panic due to really wanting it but eventually calmed enough to see what it turned out I was already looking straight towards.

Then we were off up the Loro trail (Loro = parrot, though it was a couple of days before we found that out from Rocky). It was quite steep initially and fortunately Rocky found an Ocellated Woodcreeper and stopped to get us onto it. I wasn’t going to tell him we’d seen a couple in Santa Cruz, not seeing the speed with which he’d gone off uphill. However I hadn’t really got my breath back before he was off again: the trail turned out to be a series of switchbacks in its early phase so I had some chance to settle my breathing and get into a proper walking rhythm, after which everything became a little easier, especially with stops for such delights as Red-necked Woodpecker, our third large woodpecker (this one, like Crimson-crested, Campephilus as opposed to the Lineated Dryocopus)with a vibrant scarlet head and more orangey throat, breast and belly.

Brief views of the pale blue back and scarlet cap of a Yungas Manakin were tickworthy but unsatisfactory. A Two-banded Warbler, possibly the commonest bird in the entire forest, gave better views and could thereafter be safely dismissed quickly: good because it had to be done often!

The track began to head upwards again having followed a stream for some time past boulders, waterfalls and occasional fallen trees. In places it wound back and forth across the hillside but it was almost all thickly forested and there were almost no unprotected drops to kick off my fear of heights: one exception was an awkward step over a peak in the gradient where the path surface leaned outwards and had some quite loose gravel to slip on. I got round it after a short remark to the other two about not stopping where I had no decent stance to also pause, that I hope was the only snappy criticism I made. The guys were extremely solicitous of my ability to meet my fears whenever they realized I was struggling but sometimes they wouldn’t realise a spot was even likely to cause an issue: I could understand that as I don’t always know myself and in differing conditions sometimes I react differently to the same place.

We reached a slightly better place to stop and look, with a window in the tree canopy outwards and upwards towards the cliffs now looking much closer above us on the far side of the valley. A large black silhouette glided above the void and I asked Steve “What’s the vulture?” before getting my bins settled on it and realizing there was a white ruff at the base of its naked neck: “Condor!” was my answer to my own question and I gazed enthralled at the gigantic scavenger wheeling above us. With my own fear of heights having caused Steve to leave the high Andes off the itinerary I’d hoped but not been sure that the Refugio’s list stating “Uncommon and irregular, mostly in dry season” meant we were in with a shout for the absolutely iconic Andean Condor. Key target for me and megatick - woohoo!

The track headed briefly downwards to arrive at a crossing point near the head of the stream’s valley. From there we roughly followed the base of the enormous vertical mass of sandstone with Military Macaws squawking as they paralleled the cliffs some way above us. Looking up we could see where the frequent and rapid heat-cold cycles had made the rock friable and great lumps had scabbed off to plunge to earth about where we were standing. Hopefully not today.

We made our way along the track with Rocky pointing out places where the local Spectacled Bears had pulled bromeliads from the cliffs and eaten the roots, leaving the great broad-bladed leaves loose in our path. What? That hadn’t been on our radar at all! And – er – presumably that means we could round a corner in the path and walk slap into a bear? Ooh-er…. Rocky then pointed out unmistakable bear clawmarks on the cliff face where they had been scrabbling upwards to rip away the bromeliads they desired.

Just beyond there a Black Lava Lizard perched on the steeply sloped cliff long enough for a few pictures before running effortlessly upwards on the grippy sandstone and out of sight behind some of the vegetation lodged in small cracks and where some soil had accumulated on ledges.

More to the point for me we came to a place where the path got right up to the base of the cliff and followed it before a very small switchback took it out of sight. Rocky calmly walked along a narrowing ledge, jumped across onto an embedded flat rock in a sloping fall of pulverised sandstone slanting down into the forest below and stepped up onto the upslope of the path’s continuation. I baulked, vociferously and with a good deal of basic Anglo-Saxon, before gritting my teeth while hugging the cliff and edging along the ledge to find it narrowed to nothing “ ---- me there’s nowhere to put my feet and it’s too narrow to change feet around for the next step: if I get out of here alive I’m going to move to Norfolk and never leave again!” was the least of it. Jumping was out of the question for me and when I tentatively put a foot on the nearest rock in the fall it began to slide downwards at once. Bereft of ideas and options I took an unstylish desperate dive towards a further rock, arriving on my knees and scrabbling for a handhold among exposed roots at the path’s side: I accepted a hand from Rocky for an assisting pull up to standing on firm ground with relief.

Steve followed without fuss.
