Charles van Rees - Marshbirds in Paradise: The Ecology and Conservation of the Hawaiian Gallinule
May 7, 2018
The Hawaiian Islands have experienced waves of avian extinctions during Polynesian and European colonization, becoming a hotspot for the loss of bird species. Although the plight of Hawaiian forest birds is well known, conservation issues surrounding Hawaiian waterbirds and the wetlands that support them are less well understood. This presentation integrates the full research of Charles' doctoral dissertation, which explored the impacts of habitat fragmentation, historical population declines, climate change, and conservation strategies on the extinction risk of the Hawaiian gallinule (Gallinula galeata sandvicensis). Hawaiian gallinules, an endangered subspecies of the Common gallinule endemic to Hawaii, nearly went extinct in the mid-20th century, being extirpated from all but two islands, and have shown slow population increases in the last forty years. Charles' work has asked whether the species was saved in time, or whether these modest signs of recovery are only temporary.

Dr. Geoffrey Hill - Speciation and Sexual Selection as processes to maintain Mitronuclear Coadaptation
June 4, 2018
Eukaryoic performance hinges on the coordinated function of the products of the nuclear and mitochondrial genomes in achieving oxidative phosphorylation. Because two genomes are involved, function is maintained only through perpetual selection for mitonuclear coadaptation. He will discuss how these fundamental features of the genomic architecture of eukaryotes results in both pre-and post-zygotic sorting for coadapted mitonuclear genotypes leading to both speciation and sexual selection, highlighting recent work with songbird coloration.
Dr. Geoffrey Hill is Professor of Biological Sciences, Auburn University, Alabama. He received his PhD at the University of Michigan, and did Postdoc work at Queen’s University, Canada. He is now writing 6th book on coadaptation of mitochondrial and nuclear genes. Dr. Hill’s research interests are animal coloration, sexual selection, and speciation.

Persecuted for years as a robber of game, as attitudes have slowly changed and over the past 50 years, Northern Goshawks have expanded their breeding range and increased their population size in the Northeastern U. S., including the Central Appalachians. Since 1977 Dave Brinker has studied goshawks in both Northeastern Wisconsin and the Central Appalachian…Read More
In eight groups of animals, including humans and songbirds, young animals learn to vocalize by listening to adults. Experimental evidence from laboratory studies supports this hypothesis for vocal learning, however there is no experimental evidence of vocal learning in wild animals. Dr. Mennill developed an innovative playback technology to simulate vocal tutors in the wild.…Read More
Dr. Richard (Rob) Bierregaard – Tracking Ospreys in the Age of Silicon: Migration, Ecology, and Conservation
When, in the mid 1990s, technological advances permitted us to build radio transmitters capable of sending signals to satellites orbiting the earth and small enough to place on an Osprey, windows into their lives away from the nest were thrown wide open. Thanks to bird band recoveries, we already knew that most North American Ospreys…Read More
Dr. Jonathan Regosin – Thirty Years of Piping Plover Conservation and Management in Massachusetts: Long-term Trends and Recent Developments
The Piping Plover is a state and federally threatened shorebird, with about 10,000 adults remaining, worldwide. Massachusetts has an important role to play in Piping Plover conservation, accounting for approximately 40% of the Piping Plovers breeding on the Atlantic Coast. The speaker will review 30 years of progress in Piping Plover conservation and research, challenges…Read More
With urban land expected to triple between 2000-2030, understanding the ecology of cities is sorely needed to safeguard ecosystem services, biodiversity, and our own well-being. One common target of urban conservation is birds, owing to both their charisma and sensitivity to environmental change. Though urban development is a real threat to birds across all ecosystem…Read More
Dr. James van Remsen – The cavalcade of discovery of new species and genera of South American bird … and how long will it continue?
In the 1950s, Ernst Mayr said that the age of discovery of new species of birds had largely ended. Since then, at least 125 new species of birds have been discovered in South America alone, including more than 40 by the LSU Museum of Natural Science. This represents an increase in species richness of about…Read More
Dr. Joel Cracraft – How many “kinds” of birds are there on Earth: the intersection of science and conservation policy
Scientists have long debated the idea of species, and these different conceptions have impacted the way we understand how birds evolved. These debates have also influenced people’s views of avian diversity as well as avian conservation policy. This talk will lay out these debates and show how they have real-world consequences for conserving global avian…Read More
On September 10, 2017, the Nuttall Ornithological Club was pleased to honor our Members who have been with the club for 50 or more years with a luncheon and reception, followed by a visit to the collections in the Ornithology Department at Harvard. This is an amazing group of individuals who have been not only…Read More
Major changes in world bird taxonomy are underway, driven by advances in speciation concepts and practices. World bird lists are challenged to keep up with the surge in the number of species recognized, together with their nomenclature and phylogeny. Birders are challenged to keep up with the lumps, splits, name changes, and sequences. This talk…Read More
The talk will focus on three main issues; (1) introduction to the Icelandic bird fauna; (2) seabirds and factors influencing population changes; and (3) seabird monitoring as a conservation tool. The breeding bird fauna of Iceland has rather few species, about 80, but this is made up in numbers. The principal bird groups are anseriform…Read More
