29 October – 4 November 2019
Blue-throated Macaw, the main target of the tour
Our 2019 Bolivia trip was unfortunately cut short by civil unrest from a three-week trip to a one-week trip. The tour originally had been designed to provide the best of the entire country, as it normally does on our 21-day trip, including all major habitats such as the Chiquitano dry forests and the Beni lowlands, especially looking for the endemic and Critically endangered (IUCN) Blue-throated Macaw and all the Beni-endemic subspecies. Then we were to explore the beautiful, lush forest at Refugio Los Volcanes to look for a great set of birds, including the secretive Bolivian Recurvebill, Yungas Manakin, Ochre-cheeked Spinetail, Black-streaked Puffbird, Slaty Gnateater, and Military Macaw. Next we were to visit the dry Chaco near the Paraguayan border to look for Black-legged Seriema and explore the inter-Andean forests along the valleys to look for the endemic Red-fronted Macaw and other Bolivian endemics. After driving to Cochabamba to look for all Andean endemics, including Cochabamba Mountain Finch, we would finally fly to La Paz, where we would spend several days birding around Lake Titicaca, looking for Titicaca Grebe, and around the lush Yungas forest above La Paz to look for a great set of colorful tanagers, Diademed Tapaculo, and the striking Hooded Mountain Toucan.
However, our whole tour was affected by sudden civil unrest, which paralyzed the whole country. A few days before we arrived in Bolivia there had been presidential elections, and the incumbent leader Evo Morales was trying to keep himself in power for another five-year period, even though he was not the favorite contender. The elections showed many irregularities, as pointed out by local authorities and international observers. Apparently Morales’s opponent was winning, but after certain tricky incidents such as a general power cut in the country the results showed Morales to have won. The opposition parties and the entire Santa Cruz de la Sierra population shouted fraud and started demonstrations. Oh well, we arrived two days after the civil unrest had started, and we saw the whole population of Santa Cruz de la Sierra, not only political sympathizers but the entire civilian population, fighting to reestablish democracy in the country. This spoiled our whole trip, as we were not free to drive around the main roads in the country. All roads were blocked; however, we never felt threatened nor were we ever exposed to any dangerous situation, and there were many local people who apologized to us in English for the trouble that all this was causing us but also asked us to understand that they had to fight for their rights.
We managed to travel to the Beni province and had a great week of birding there with a fine series of good species, such as Greater Rhea, Campo Flicker, Great Rufous Woodcreeper, Red-billed Scythebill, Velvet-fronted Grackle, Plain Softtail, Grey-crested Cachalote, Blue-and-yellow, Chestnut-fronted, and Red-and-green Macaws, Sunbittern, Hoatzin, Bare-faced Curassow, hundreds of Jabirus and Wood Storks, Plumbeous, Green, Bare-faced, and Buff-necked Ibises, South American Snipe, White Monjita, White Woodpecker, Red-winged and Undulated Tinamous, and, most importantly, also our main target, the endemic and Critically endangered Blue-throated Macaw.
After a week in Beni we were forced to cancel the trip and return to our countries, because the demonstrations were becoming violent and towns started to experience shortages of basic supplies. We also certainly did not want to be involved in any skirmish between army and civilians. For us security was first, and so we abandoned the country. The demonstrations continued for about two months after we left and ended with the resignation of Morales, who asked for political asylum in Mexico and later in Argentina.
Bolivia is recovering gradually from its political crisis, and we will come back to get our revenge and find all the birds that this great country has to offer.
Day 1, October 29th 2019. Arrival in Santa Cruz de la Sierra and transfer to the hotel
Our birding adventure started in the city of Santa Cruz de la Sierra, where the group arrived on different flights, and we met at the comfortable Hotel Cortez. We made plans for the next day and enjoyed a good meal together at the restaurant in the hotel.
Day 2, October 30th 2019. Birding around Santa Cruz de la Sierra
This was our first day trying to get out of a city with a national demonstration. It was absolutely tricky to find the way out of the city. The demonstration was generally all over the city, and the driver had to perform miracles to find his way through narrow streets to unpaved roads and dealing with lots of civilian checkpoints, but we managed to get out of the city in good time for birding.
We drove east of the city toward the shores of the Piray River, where we had a busy morning finding species such as Toco Toucan, White-wedged Piculet, Chopi Blackbird, Yellow-chevroned Parakeet, Gilded Sapphire, Pale-vented Pigeon, Guira Cuckoo, Rufous-tailed Jacamar, Chestnut-eared Aracari, Yellow-tufted Woodpecker, Blue-winged Parrotlet, Green-barred Woodpecker, White-crested Tyrannulet, Crowned Slaty Flycatcher, Purplish Jay, Sayaca Tanager, Purple-throated Euphonia, and Crested Oropendola.
We went to check a reservoir, where we managed to have great views of Ringed Teal, White-cheeked Pintail, White-winged Coot, Brazilian Teal, and Neotropic Cormorant. After a few minutes we left toward the shore of the Piray River. Here we saw good species such as Yellow-chinned Spinetail, Southern Lapwing, Picui Ground Dove, Fawn-breasted Wren, Southern Screamer, Brazilian Teal, Black-bellied Whistling Duck, Wattled Jacana, Limpkin, Solitary Sandpiper, Whistling Heron, White-tailed Kite, Black and Turkey Vultures, Rufous Hornero, Southern Crested Caracara, Southern Scrub Flycatcher, and Monk Parakeet.
After a tasty lunch in a private hacienda we headed back to the city to the Viru Viru International Airport, where after a drive around I spotted one of the main two targets for the afternoon, Red-winged Tinamou, and minutes later we saw Campo Flicker. We can say that, even though it had not been the original plan, we returned happy to the hotel with the hope that the social unrest could be fixed as fast as possible.

Day 3, October 31st 2019. Flight to and birding around Trinidad
We had another early start, leaving the hotel with enough time to get our domestic flight to Trinidad in the Beni state. Driving from the hotel to the airport took much longer than usual but was expected under the uncertain scenario we were witnessing in the country. The flight left without any problems, though, and we were in business. After arrival in Trinidad we met our local contact, who after some confusing minutes put us on the road directly to our hotel at the shores of the pretty Laguna Suárez outside the bustling town. After checking some birds around the hotel and getting our first lunch together as a group we left to explore the road to Loreto. The Beni lowlands in the Pampa de Moxos shows a complex mixture of habitats of grasslands, marshes, forest islands, and corridors of forests along waterways to look for one of the rarest birds in the world, the endemic and Critically endangered Blue-throated Macaw. Today it is only possible to find a few accessible spots in the Beni lowlands where the palms the macaw uses for nesting are still growing in good numbers. Our first day in the Beni lowlands was a blast. We had great views of species such as Plumbeous Ibis, Buff-necked Ibis, Southern Screamer, Greater Rhea, Southern Lapwing, Eastern Kingbird, Fork-tailed Flycatcher, Black-backed Water Tyrant, Cattle Tyrant, Yellow-chevroned Parakeet, Monk Parakeet, Chestnut-fronted Macaw, Wood Stork, Jabiru, Snail Kite, Black-collared Hawk, Whistling Heron, Great Egret, Snowy Egret, Limpkin, Chaco Chachalaca, and Ringed Kingfisher.
We found a huge wetland on one side of the road with one of the largest numbers of Wood Storks I have seen for years. It was also full of Jabirus, Wood Storks, Maguari Storks, South American Snipe, Collared Plover, and Baird’s, Pectoral, and Solitary Sandpipers. We also had views of Black-capped Donacobius, Yellow-chinned Spinetail, White-rumped Monjita, Crested Becard, Lesser Kiskadee, Turquoise-fronted Amazon, and Green Kingfisher. After this great experience we returned to Laguna Suárez and called it a day.

Day 4, November 1st 2019. Birding along the Loreto road, search for Blue-throated Macaw
We had an early start leaving our base in Laguna Suárez to drive to the town of Loreto. Here we met our local contact, who led us to one of the haciendas along the Loreto road where the Blue-throated Macaw is quite reliable. We arrived at the hacienda, and the person in charge of visitors pointed out two potential stakeouts for the species. We could feel the excitement in the air when suddenly there was a pair of Blue-throated Macaws coming toward us and perched in a tree, where we could get great scope views. Sadly they did not stay around long enough to allow everybody to take a photo.
Birding around the hacienda we could add more species to the trip list, such as Narrow-billed Woodcreeper, White Woodpecker, Lineated Woodpecker, Streaked Flycatcher, Boat-billed Flycatcher, and Red-billed Scythebill.
It was getting warm already, so we birded outside the hacienda, finding Yellow-headed Caracara, Southern Crested Caracara, Ochre-faced Tody-Flycatcher, Common Tody-Flycatcher, Barred Antshrike, Mato Grosso Antbird, Red-and-green Macaw, and Toco Toucan. Then we returned to Laguna Suárez and spent the afternoon photographing birds around the hotel grounds, such as Grey-crested Cacholote, Orange-backed Troupial, and Greater Thornbird.
Even though the socio-political situation in Trinidad was calm we received a phone call from our airline saying that due to the recent demonstrations in Santa Cruz de la Sierra they decided to cancel our flight back to Santa Cruz de la Sierra for two days! So being literally trapped in Trinidad we were thankful about our comfortable hotel in Laguna Suárez away from all the political problems, but we also had to make alternative plans for the next two days. We had been hoping that after our return the demonstrations would be over and we would be able to continue with our itinerary, but after hearing from the airline I started to think that things could take longer to be fixed.
At night we tried to find a Spot-tailed Nightjar that was calling from the other side of the road, but unfortunately it did not come any closer and the terrain was quite inaccessible.
Day 5, November 2nd 2019. Birding Chuchini Amazon Wildlife Reserve
We decided to spend a morning looking for Beni specialists and found an accessible birding site near Trinidad called Chuchini Amazon Wildlife Reserve. Driving through Trinidad was no problem at all, and we arrived at the reserve rather quickly. There was good activity even outside the reserve, including species such as Snowy Egret, Great Egret, Cocoi Heron, a glimpse of Sunbittern, Large-billed Tern, Yellow-billed Tern, Grey-fronted Dove, Sayaca Tanager, Palm Tanager, Hoatzin, Blue-throated Piping Guan, White-winged Swallow, Southern Rough-winged Swallow, Ruddy Ground Dove, Picui Ground Dove, Greater Ani, Plumbeous Kite, Guira Cuckoo, Lesser Yellow-headed Vulture, Chestnut-fronted Macaw, and Roadside Hawk. Before getting into the reserve we found our targets, a nice flock of Velvet-fronted Grackles, which provide great views, and a Plain Softtail in a nest! Both are contenders for future splits; Beni Grackle and Beni Softtail would actually sound better!
Then we entered the reserve and explored part of a trail, looking for a Great Potoo that we were told was roosting at daytime, but we could not find. It was slightly late and hot, so after a nice late-start morning we returned to the hotel, where we continued thinking about our strategies and options for the upcoming days.
Day 6, November 3rd 2019. Birding Chuchini Amazon Wildlife Reserve
We returned to the reserve early in the morning to explore the forest trails, and we saw a good set of birds including Spix’s Guan, Black-tailed Trogon, Blue-crowned Trogon, Black-fronted Nunbird, Yellow-billed Cuckoo, Velvet-fronted Grackle, Plain-crowned Spinetail, Chestnut-backed Antshrike, White-backed Fire-eye, Band-tailed Antbird, Black-throated Mango, White-chinned Sapphire, Buff-bellied Hermit, Olivaceous Woodcreeper, Buff-throated Woodcreeper, Great Rufous Woodcreeper, Band-tailed Manakin, White-eyed Attila, Yellow-olive Flatbill, Masked Tityra, and Black-crowned Tityra. In addition we had an enjoyable encounter with a pair of Undulated Tinamous coming toward us in response to the tape. We also found Rufous-tailed Jacamar, Crimson-crested Woodpecker, Golden-crowned Warbler, Fawn-breasted Wren, Orange-backed Troupial, Silver-beaked Tanager, White-winged Becard, White-eyed Parakeet, Purplish Jay, Short-crested Flycatcher, and Red-crested Cardinal, and sadly a shy male Bare-faced Curassow crossed the trail in front of us and was seen only by me and one participant.
After a full morning we returned to Trinidad, where we enjoyed lunch at the famous restaurant Churrasquería La Estancia. Then we went back to the lodge to prepare ourselves for the next day’s flight to Santa Cruz de la Sierra. In the late afternoon there was a wonderful view outside the hotel with a beautiful sunset, which was nicely captured by Anne.
Day 7, November 4th 2019. Flight to Santa Cruz de la Sierra, departure
After breakfast we transferred to the Trinidad airport to connect with our flight to Santa Cruz de la Sierra. When we arrived at Santa Cruz de la Sierra we were informed that the socio-political situation in Bolivia had become worse than we had expected, because the opposition and most of the Bolivian population had given the president 24 hours to resign, otherwise they threatened the government with an undefined strike that could turn serious and difficult for travelers. There was no way to continue with our itinerary, as the main roads were all blocked and the lack of basic supplies in the country-side lodges could be a potential risk in the following days. We feared that the situation could get even worse, and although we were very sad we decided to cancel our tour and change our flights to return to our respective countries. We spent the afternoon dealing with the airlines and changing our flights and managed to leave the country that very day.
Only five hours after we had left the civil unrest became worse in the whole country with skirmishes between the supporters of the opposition on the one hand and the army and police on the other. Nevertheless it is good to say that the civil unrest ended with the end of the government of Evo Morales and the country experienced a serious change of government, but the riots and demonstrations took over two months after we had left. So I guess we were lucky to have left on that day. There’s nothing else to say except that despite all the hassle, which was out of our hands, we managed to spent a great week and cleaned up the entire Beni region. We are happy to see that the situation is gradually improving, and we will return to Bolivia to claim vengeance and get all our missing birds!

Hoatzin Opisthocomus hoazin Seen in the Chuchini Amazon Wildlife Reserve in Beni. Nahuatl (Mexican) Indian name uatsin for some kind of large bird, probably not the Hoatzin, which does not occur in Middle America, but a gamebird. The name is said to be onomatopoeic in origin and has been variously transcribed as hoactzin, hoactli, hoatzin, hoacton, hoazin, heatotl and tobactli. Hernández (1615) gives hoactli and hoacton as Mexican Indian names for the adult and the young Black-crowned Night-Heron Nycticorax nycticorax respectively. The taxonomic position of this family has been greatly debated by specialists and is still far from clear. A whole genome sequencing study published in 2012 places the Hoatzin as the sister taxon of a clade composed of Gruiformes (cranes) and Charadriiformes (plovers). In 2015 genetic research indicated that the Hoatzin is the last surviving member of a bird line that branched off in its own direction 64 million years ago, shortly after the extinction of the dinosaurs.

Blue-throated Macaw Ara glaucogularis Great views of a pair in the Loreto haciendas. This is a Bolivian endemic. A Critical endangered species. In 2014 this species was designated by law has a natural patrimony of Bolivia, where it is known as barba azul, which means ‘blue beard’ in Spanish. Recent population and range estimates suggest that about 350–400 individuals remain in the wild. The main cause of their demise is capture for the pet trade. The blue-throated macaw lives in the Llano de Moxos of the Beni Department of Bolivia, nesting in “islas” (islands) of palm trees that dot the level plains. It is not a forest-dwelling bird. This species is one of the rarest in the world. There are two areas inhabited by two subpopulations of Ara glaucogularis: one is to the northwest of Trinidad (the capital city of Beni), and the other is to the south of Trinidad. This complex landscape consists of grasslands, marshes, forest islands, and corridors of forests along waterways. They occur most often between the elevations of 200 and 300 meters (656 and 984 feet). It was rediscovered only in 1992.
