Dr. Wilson will be flanked by Peter Alden who will introduce him and guide a lively Q&A from Nuttall and audience members.  Dr. Robert Ridgely will end with a short, illustrated presentation on the history of the Cordillera Azul Antbird recently named for Dr. Wilson. Edward O. Wilson is recognized as one of the creators…

Dr. Mizrahi will review 20 years of research to unravel connectivity in Semipalmated Sandpipers populations throughout the annual cycle and determine what factors during the winter, migration and breeding periods underlie significant declines in populations, especially those migrating through the Western Atlantic region. He will also discuss conservation efforts that address several of the major…

Nils will talk about the migration and conservation of shorebirds around the Pacific Basin, focusing on studies he and collaborators have done over the past 30 years.  His initial research focused on the migration of small shorebirds like the Western Sandpiper and the Dunlin through western North America. More recent work looked at large-scale movements…

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…

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…

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…

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.…

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…

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…

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…

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…

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…

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…

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…

As an evolutionary biologist I seek to understand how biological diversity is generated at the molecular level. I study a group of South American birds known as capuchino seedeaters, which may still be in the process of becoming species. Capuchinos are sexually dimorphic, and males from different species differ in secondary sexual characters such as…

Woodpeckers peck on trees to feed on insects and sap, to build cavity nests and to drum during courtship. Measurements by a group of neurologists in the 1970s, using high speed video, indicate that woodpeckers can tolerate remarkably high decelerations on impact: up to 1500g, much higher than the level of 100g that causes brain…

Avian brood parasites and their hosts have served as important models of coevolution and have produced a spectacular diversity of behavioral, morphological and physiological adaptations and counter-adaptations, our knowledge of which has expanded as additional species in Asia and the southern hemisphere have received intensive study. Until recently, essentially nothing was known about the genetic…

This presentation focuses on Tom’s energetic crusade to rebuild the American Kestrel population in northeast Connecticut, from 2009 when he began, up through the 2016 breeding season. Presented on January 9, 2017.

This talk describes the status of tidal marsh birds throughout the northeast, and focuses on the specific threats faced by Saltmarsh Sparrows. Presented on December 5, 2016.

Endemic and Endangered Birds of Bolivia. Presented November 7, 2016.
