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. -

Galapagos Islands Fact Sheet Galapagos Islands Fact Sheet
GALAPAGOS ISLANDS FACT SHEET GALAPAGOS ISLANDS FACT SHEET INTRODUCTION The Galapagos Islands are located west of Ecuador and are renowned for being the home to a vast array of fascinating species of wildlife, including lava lizards, the giant tortoise as well as red and blue-footed boobies. They are one of the world’s foremost destinations for wildlife viewing, many of the plant and animal species being found nowhere else in the world. Located at the confluence of three ocean currents and surrounded by a marine reserve, the islands abound with marine species. The Galapagos Islands, of which there are 19 main islands, are an archipelago of volcanic islands in the Pacific Ocean. They lay either side of the Equator and 1,000km west of the South American continent and mainland Ecuador of which they are a part. The islands were formed as a result of processes caused by volcanic and seismic activity. These processes along with the isolation of the islands resulted in the development of unusual animal life. Charles Darwin’s visit to the islands in 1835 was the inspiration for his theory of evolution by natural selection. The largest island Isabela, measures 5,827 square kilometres and accounts for nearly three quarters of the total land area of the Galapagos. Volcan Wolf on Isabela is the highest point of the Galapagos at 1,707m above sea level. GALAPAGOS ISLANDS FACT SHEET CLIMATE The Galapagos Islands have a subtropical and dry climate with comfortable temperatures year-round. The warmest months are usually from December to June (high season) and this is the recommended time to visit. -
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). -

The predominant vegetation in the highlands are Scalesia trees which create a lush green forest. The lava tunnels, over half a mile long, are underground and walking through them is a unique, surreal experience. At this place you’ll have lunch.

Lamichhaney Et Al. 2015. Evolution of Darwin's Finches and Their Beaks

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. -

Abstract: Darwin’s finches are a classic example of adaptive radiation involving differential use of dietary resources among sympatric species. Here, we apply stable isotope (δ13C, δ15N, and δ2H) analyses of feathers to examine ecological segregation among eight Darwin’s finch species in Santa Cruz Island, Galápagos collected from live birds and museum specimens (1962–2019). We found that δ13C values were higher for the granivorous and herbivorous foraging guilds, and lower for the insectivorous finches. Values of δ15N were similar among foraging guilds but values of δ2H were higher for insectivores, followed by granivores, and lowest for herbivores. The herbivorous Citation: Villegas, M.; Soos, C.; guild generally occupied the largest isotopic standard ellipse areas for all isotopic combinations Jiménez-Uzcátegui, G.; Matan, S.; and the insectivorous guild the smallest.
