The Predominance of Wild-Animal Suffering Over Happiness: an Open
The Predominance of Wild-Animal Suffering over Happiness: An Open Problem Abstract I present evidence supporting the position that wild animals, taken as a whole, experience more suffering than happiness. This seems particularly true if, as is possible if not very likely, insects1 can suffer, since insects have lifespans of only a few weeks and are orders of magnitude more preponderate than other animals. I do not know what should be done about this problem, but I propose that further work on the subject might include • Continued study of whether insects are sentient, • Investigation of the effects (negative and positive) of various types of environ- mental destruction on wild-animal welfare, and • Research on ways to alleviate the pain endured by animals in the wild, especially that of insects and other small animals. Of course, even if wild-animal lives are generally worth living, efforts to reduce their suffering may still be worthwhile. I encourage readers to contact me with any insights into these issues: webmaster [\at"] utilitarian-essays.com 1 Introduction The fact that in nature one creature may cause pain to another, and even deal with it instinctively in the most cruel way, is a harsh mystery that weighs upon us as long as we live. One who has reached the point where he does not suffer ever again because of this has ceased to be a man. |Albert Schweitzer [31, Ch. 3] Many advocates of animal welfare assume that animals in the wild are, on the whole, happy. For instance, the site utilitarian.org includes a proposal to create a wildlife reserve, the main \Utility value" of which would come from \The value of life over death for the animals who will live there" [62]. -

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). -

Bennett The Journal of Caribbean Ornithology jco.birdscaribbean.org ISSN 1544-4953 RESEARCH ARTICLE Vol. 31:38–47. 2018 www.birdscaribbean.org New sightings of melanistic Green HeronsButorides ( virescens) in the Caribbean suggest overlooked polymorphism Jacob R. Drucker1, Ruth E. Bennett2,3, Lila K. Fried4, Mona L. Kazour5, and Darin J. McNeil, Jr.2,6 Abstract Intraspecific variation in animal coloration arises from the expression of heritable genes under different selection pressures and stochastic processes. Documenting patterns of intraspecific color variation is an important first step to under- standing the mechanisms that determine species appearance. Within the heron genus Butorides, plumage coloration varies across space, among distinct taxonomic groups, and within polymorphic populations. The melanistic Lava Heron (B. striata sundevalli) of the Galápagos has been the subject of considerable taxonomic confusion and debate, while an erythristic morph of Green Heron (B. virescens) has been largely overlooked in recent literature. Here we report a new sighting of three melanistic individuals of Green Heron from Útila, Bay Islands, Honduras, in February 2017. In light of our discovery, we conducted a review of aberrantly plumaged Green Herons and present evidence for the existence of two previously unrecognized color morphs, both primarily found in coastal mangroves of the western Caribbean region. We are the first to formally describe a melanistic morph of Green Heron and discuss the widespread and highly variable erythristic morph within the context of a color-polymor- phic Green Heron. -

Trip Report Assam Extension I 17th to 21st March 2015 (5 days) Greater Adjutant by Glen Valentine Tour leaders: Glen Valentine & Wayne Jones Trip report compiled by Glen Valentine Trip Report - RBT Assam Extension I 2015 2 Top 5 Birds for the Assam Extension as voted by tour participants: 1. Pied Falconet 4. Ibisbill 2. Greater Adjutant 5. Wedge-tailed Green Pigeon 3. White-winged Duck Honourable mentions: Slender-billed Vulture, Swamp Francolin & Slender-billed Babbler Tour Summary: Our adventure through the north-east Indian subcontinent began in the bustling city of Guwahati, the capital of Assam province in north-east India. We kicked off our birding with a short but extremely productive visit to the sprawling dump at the edge of town. Along the way we stopped for eye-catching, introductory species such as Coppersmith Barbet, Purple Sunbird and Striated Grassbird that showed well in the scopes, before arriving at the dump where large frolicking flocks of the endangered and range-restricted Greater Adjutant greeted us, along with hordes of Black Kites and Eastern Cattle Egrets. Eastern Jungle Crows were also in attendance as were White Indian One-horned Rhinoceros and Citrine Wagtails, Pied and Jungle Mynas and Brown Shrike. A Yellow Bittern that eventually showed very well in a small pond adjacent to the dump was a delightful bonus, while a short stroll deeper into the refuse yielded the last remaining target species in the form of good numbers of Lesser Adjutant. After our intimate experience with the sought- after adjutant storks it was time to continue our journey to the grassy plains, wetlands, forests and woodlands of the fabulous Kaziranga National Park, our destination for the next two nights. -

Photo by Desmond Sieburth of Los Angeles, California: Golden-cheeked Woodpecker (Melanerpes chrysogenys) San Blas, Nayarit, Mexico, 30 December 2016 Endemic to western mainland Mexico from Sinaloa south to Oaxaca, the Golden-cheeked Woodpecker comprises two well-differentiated subspecies. In the more northern Third-cycle (or possibly second-cycle) Herring Gull at New Buffalo, Michigan, on M. c. chrysogenys the hindcrown of both sexes is largely reddish with only a little 14 September 2014. Unlike the other birds illustrated on this issue’s back cover, in this yellow on the nape, whereas in the more southern M. c. flavinuchus the hindcrown is individual the pattern of the inner five primaries changes gradually from feather to uniformly yellow, contrasting sharply with the forehead (red in the male, grayish white feather, with no abrupt contrast. Otherwise this bird closely resembles the one on the in the female). The subspecies intergrade in Nayarit.

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).
