Ecuador Galápagos Archipelago 26Th April to 5Th May 2018 (10 Days) Trip Report
Ecuador Galápagos Archipelago 26th April to 5th May 2018 (10 days) Trip Report Waved Albatross by Dušan Brinkhuizen Trip report compiled by Tour Leader: Dušan Brinkhuizen Rockjumper Birding Tours View more tours to Ecuador Trip Report – RBL Ecuador - Galápagos Archipelago 2018 2 Tour Summary Rockjumper’s amazing Galápagos adventure started at the airport of San Cristobál – the easternmost island of the archipelago. Our first bird of the trip was a stunning Mangrove Warbler hopping in the arrivals hall! Mangrove Warbler is a split from American Yellow Warbler and the distinct race aureola is only found in the Galápagos and Cocos Island. Some people saw the first Darwin’s finches from the bus during a short drive to our hotel in town. After a delicious lunch in a restaurant (lots of fresh fish available on the islands!), we started our afternoon excursion to the highlands of San Cristobál. The walk up to El Junco lagoon was scenic. We got close encounters with Grey Warbler-Finch of the San Cristobál race and also identified our first Small and Medium Ground Finches. We got to the lake just before a thick ocean mist came in. The crater lake was formed by the collapsed caldera of a volcano and is the only freshwater site on the island. It’s a great place to watch Magnificent Frigatebirds come to drink in an almost surreal setting. It was Steve that picked out a female Great Frigatebird – a scarcer species here – that we identified by the red eye-ring. White- Grey Warbler-Finch by Dušan cheeked Pintails with ducklings were present on the lake, as Brinkhuizen well as a few Common Gallinules. -

Day 1 Monday 29th January UK to Quito People arrived in Quito via Amsterdam with KLM or via Madrid with Iberia, while Tony came separately from the USA. Everyone was met at the airport and taken to the Hotel Vieja Cuba; those who were awake enough went out to eat before a good night’s rest. Day 2 Tuesday 30th January Quito. Weather: Hot and mostly sunny. The early risers saw the first few birds of the trip outside the hotel: Rufous- collared Sparrow, Great Thrush and Eared Doves. After breakfast, an excellent guide took us on a bus and walking tour of Quito’s old town. This started with the Basilica del Voto Nacional, where everyone marvelled at the “grotesques” of native Ecuadorian animals such as frigatebirds, iguanas and tortoises. -

Can Darwin's Finches and Their Native Ectoparasites Survive the Control of Th
Insect Conservation and Diversity (2017) 10, 193–199 doi: 10.1111/icad.12219 FORUM & POLICY Coextinction dilemma in the Galapagos Islands: Can Darwin’s finches and their native ectoparasites survive the control of the introduced fly Philornis downsi? 1 2 MARIANA BULGARELLA and RICARDO L. PALMA 1School of Biological Sciences, Victoria University of Wellington, Wellington, New Zealand and 2Museum of New Zealand Te Papa Tongarewa, Wellington, New Zealand Abstract. 1. The survival of parasites is threatened directly by environmental alter- ation and indirectly by all the threats acting upon their hosts, facing coextinction. 2. The fate of Darwin’s finches and their native ectoparasites in the Galapagos Islands is uncertain because of an introduced avian parasitic fly, Philornis downsi, which could potentially drive them to extinction. 3. We documented all known native ectoparasites of Darwin’s finches. Thir- teen species have been found: nine feather mites, three feather lice and one nest mite. No ticks or fleas have been recorded from them yet. 4. Management options being considered to control P. downsi include the use of the insecticide permethrin in bird nests which would not only kill the invasive fly larvae but the birds’ native ectoparasites too. 5. Parasites should be targeted for conservation in a manner equal to that of their hosts. We recommend steps to consider if permethrin-treated cotton sta- tions are to be deployed in the Galapagos archipelago to manage P. downsi. Key words. Chewing lice, coextinction, Darwin’s finches, dilemma, ectoparasites, feather mites, Galapagos Islands, permethrin, Philornis downsi. Introduction species have closely associated species which are also endangered (Dunn et al., 2009). -
Observations on the Breeding and Distribution of Lava Gull Leucophaeus Fuliginosus K
Cotinga 37 Observations on the breeding and distribution of Lava Gull Leucophaeus fuliginosus K. Thalia Grant, Olivia H. Estes and Gregory B. Estes Received 7 January 2014; final revision accepted 3 December 2014 Cotinga 37 (2015): OL 22–37 published online 10 March 2015 La Gaviota de Lava Leucophaeus fuliginosus, endémica del archipiélago de Galápagos, es la gaviota más rara del mundo, cuyos hábitos de reproducción son poco conocidos. En los años 2011 y 2012 se observó anidación en la isla Genovesa en densidades mayores a las reportadas previamente en Galápagos. Las parejas reproductoras fueron muy territoriales, defendiendo áreas de hasta 70 m de diámetro contra coespecíficos. Las hembras fueron más agresivas que los machos frente a los intrusos de otras especias percibidos como una amenaza. La nidada de 1–2 huevos fue incubada por ambos miembros de la pareja en turnos de dos horas. Los polluelos salieron del nido 4–5 días después de la eclosión, seleccionando lugares en el territorio más protegidos a los cuales retornaron regularmente para descansar. Los adultos reproductores fueron depredadores oportunistas, alimentando a sus crías principalmente con huevos y polluelos de aves marinas y peces robados de las mismas aves. Reconocemos una relación parasítica entre la cleptoparásita Fragata Real Fregata magnificens y la Gaviota de Lava, y sospechamos que este es el medio principal por el cual en esta isla las gaviotas adquieren los peces que comen. Presentamos datos sobre las comunicaciones entre los padres y la cría, proporcionamos la primera serie de fotografías del desarrollo del polluelo de Gaviota de Lava y describimos una característica en el plumaje de los adultos que no ha sido descrita previamente. -

In each case, sympatric species are generalist; expected to evolve into distinct ecological niches, such as different food Geospiza; types, yet this expectation is not always met when such species are exam- ground finches; ined in nature. The most common hypotheses to account for the coexistence niche partitioning; of species with substantial diet overlap rest on temporal variation in niches resource use; (often diets). Yet spatial variation in niche overlap might also be important, specialist; pointing to the need for spatiotemporal analyses of diet and diet overlap sympatry. between closely related species persisting in sympatry. We here perform such an analysis by characterizing the diets of, and diet overlap among, four sympatric Darwin’s ground finch species at three sites and over 5 years on a single Galapagos island (Santa Cruz). -

Galápagos Natural History Extravaganza
GALÁPAGOS NATURAL HISTORY EXTRAVAGANZA 21 NOVEMBER – 02 DECEMBER 2021 2022 (DATES ON REQUEST) 29 OCTOBER – 09 NOVEMBER 2023 Red-footed Booby is one of three booby species likely to be found on this trip. www.birdingecotours.com [email protected] 2 | ITINERARY Galapagos: Natural History Extravaganza Just 483 years ago the first man stepped onto the Galápagos Islands and marveled at this living laboratory. Today we continue to be awestruck by this constantly changing archipelago. As the Nazca Plate moves and new islands are formed, evolution is illustrated up close and personal. Visiting the Galápagos archipelago is a dream for all naturalists. From Quito we will fly to the island of Baltra. We then will make our way to our home for the next eight days, the Samba, a spacious and luxuriously designed motor sailing yacht with wide open and shaded sun decks, a fully stocked bar, and a library. The abundant marine life that visits these waters year-round, the Marine Iguanas that rule the rocky coastlines, and of course a unique group of birds make it easy to understand why this trip is a must for birders and natural history buffs. Some of the Galápagos specials that we hope to find on this trip include Galapagos Penguin, Waved Albatross, Galapagos Shearwater, Wedge-rumped and Elliot’s Storm Petrels, Magnificent Frigatebird, Nazca, Red-footed, and Blue-footed Boobies, Lava Heron, Galapagos Hawk, Lava Gull, Galapagos Martin, Galapagos Flycatcher, Vermilion Flycatcher, Galapagos, Floreana, San Cristobal, and Espanola Mockingbirds, Vegetarian Finch, Woodpecker Finch, Common Cactus Finch, Green Warbler-Finch, Large and Small Tree Finches, Small and Medium Ground Finches, and Mangrove Finch. -
Lamichhaney Et Al. 2015. Evolution of Darwin's Finches and Their Beaks
ARTICLE doi:10.1038/nature14181 Evolution of Darwin’s finches and their beaks revealed by genome sequencing Sangeet Lamichhaney1*, Jonas Berglund1*, Markus Sa¨llman Alme´n1, Khurram Maqbool2, Manfred Grabherr1, Alvaro Martinez-Barrio1, Marta Promerova´1, Carl-Johan Rubin1, Chao Wang1, Neda Zamani1,3, B. Rosemary Grant4, Peter R. Grant4, Matthew T. Webster1 & Leif Andersson1,2,5 Darwin’s finches, inhabiting the Gala´pagos archipelago and Cocos Island, constitute an iconic model for studies of speci- ation and adaptive evolution. Here we report the results of whole-genome re-sequencing of 120 individuals representing all of the Darwin’s finch species and two close relatives. Phylogenetic analysis reveals important discrepancies with the phenotype-based taxonomy. We find extensive evidence for interspecific gene flow throughout the radiation. Hybrid- ization has given rise to species of mixed ancestry. A 240 kilobase haplotype encompassing the ALX1 gene that encodes a transcription factor affecting craniofacial development is strongly associated with beak shape diversity across Darwin’s finch species as well as within the medium ground finch (Geospiza fortis), a species that has undergone rapid evolution of beak shape in response to environmental changes. The ALX1 haplotype has contributed to diversification of beak shapes among the Darwin’s finches and, thereby, to an expanded utilization of food resources. Adaptive radiations are particularly informative for understanding the diversification throughout phylogeny, and report the discovery of a locus ecological and genetic basis of biodiversity1,2. Those causes are best iden- with a major effect on beak shape. tified in young radiations, as they represent the early stages of diver- sification when phenotypic transitions between species are small and Considerable nucleotide diversity interpretable and extinctions are likely to be minimal3.
