The Hawaiian Archipelago is the most isolated chain of islands in the world, over twenty-five hundred miles from the nearest continent.  Very few plants and animals have ever reached these remote islands on their own, but those that did, evolved over time and became unique to the Islands.  About five and a half million years ago,  a small flock of finch like birds from Asia, likely blown off course, arrived in the Hawaiian islands.  Unrestricted food supplies and adaptations through competition for these food resources created evolutionary opportunities for speciation through specialization of bill forms and body size.  From this one colonization the Hawaiian Honeycreepers evolved into over fifty different bird species found nowhere else on earth.  Some Honeycreepers, like the scarlet I’iwi, evolved long curved bills to feed on nectar in the curved flowers of native plants,  like those of the Bell flower family or Lobelias and provide for their pollination.  Other bird species adapted to feed on insects in different ways. For example, the tiny Hawaii Akepa, with its short straight bill, crossed at the tip,  gleans micro insects from leaf buds.  The Akialoa’s long thin bill, almost as long as its body, was used to poke deep into tree crevices to find insects that no other bird could reach.  The Akiapola’au has one of the most unusual bills in the bird world.  Its upper bill is long, thin and down curved, and lower bill short straight and stout feeds like a woodpecker, but with its mouth open.  It pecks into the tree wood with its lower short-stout bill, then uses the upper long curved bill to reach into the hole to wrench out wood-boring beetle larvae.  Today, only 17 Hawaiian Honeycreepers species remain in the Islands, but with continued habitat protection and restoration as is happening at Hakalau Forest NWR on Hawaii Island and other areas in the State, as well as captive breeding and release, and active research on control of mosquitoes and avian diseases, the remaining Hawaiian Honeycreepers will hopefully survive far into the future. 

California has roughly 40 million acres of rangelands that provide food production, carbon sequestration, water infiltration, and habitat for a wide range of species. However, this historic land use is under threat with an average of 20,000 acres a year being lost to development or crop conversion. Climate change, invasive species, aquifer depletion, and outdated grazing practices also degrade large portions of grasslands, increasing economic and ecological vulnerability. This in turn has contributed to steep declines in grassland bird species across California and the United States.

Audubon launched its Conservation Ranching program (ACR) here in California in 2019. This program is designed to stem the conversion of grassland ecosystems and improve the ecological functions of rangelands by partnering with ranchers to transition to more regenerative grazing approaches via a ranch certification program. This presentation will highlight the ACR program components which includes the development of ranch-specific Habitat Management Plans and a third-party certified set of regenerative grazing practices to increase climate-driven drought resiliency, rebuild soil organic matter, enhance plant diversity and cover, increase water infiltration and carbon sequestration, and increase overall biodiversity. This ecological resilience can translate to economic resilience, as participating producers are able to use the Audubon certification logo on their product – providing a market incentive to landowners to enroll in this program through increased sales or revenue. This presentation will highlight program practices, early results and opportunities for enrollment.

John will share highlights from his tours’ adventures in Morocco. With its high mountains, high desert, low Sahara desert, agricultural plains, coastal lagoons, cork oak woodland, and coniferous forest, Morocco has much to offer to birds and birders. Home to several endemic bird species as well as North Africa species not readily seen elsewhere, it is also along the major migratory pathway for European migrants including shorebirds, raptors, songbirds and others. Join us for a virtual tour of the country’s birds, landscapes and culture.

Description: Purple martins have been in long-term decline in California. Since the 1990s, Dan Airola has been studying and working to conserve the last Central Valley population, which nests in elevated freeways and overpasses in Sacramento. He also has conducted status surveys throughout Northern California.  His talk presents these study results and describes conservation measures that have been implemented and are needed to protect and recover the species.

Biography: Dan Airola is a Wildlife Biologist and Ornithologist who has worked for over 40 years on bird conservation issues in Northern California.  His recent research has addressed status, ecology, migration, and conservation of at-risk species, including the Tricolored Blackbird, Swainson’s Hawk, Yellow-billed Magpie, fire-adapted forest species, and migrant songbirds.  Dan also serves the Central Valley Bird Club as a Director, Conservation Chair, and editor of the journal Central Valley Birds.

Biography: 

Robert received a PhD in French from the University of Wisconsin, became a university professor, but eventually left academia to pursue a career in computer technology consulting.

He began photographing birds in preparation for a safari in Botswana. What better way to learn how to use a camera than photographing birds, he reasoned. Birds eventually became his favorite photographic subject. “I’ve never met a bird I didn’t want to photograph,” he admits.

His photograph of a Cedar Waxwing was selected to appear in a special Audubon Photography Awards gallery of  “our favorite female bird shots 2021.”

Choosing to be a bird photographer necessitated becoming an avid birder, and that pursuit led to storytelling about his experiences observing birds.

Description: 

Since the dawn of recorded history, humans have wanted to fly like the birds. Although many studied the secret of avian flight during the Renaissance and the Enlightenment, it was not until the Industrial Revolution that the technological tools for humanity to fly became available. By the mid and late 1800s, spurred on by the science of bird flight, dozens of people, and the Wright Brothers were not the first, were attempting to master human flight. This culminated in the early 20th century with pioneering aviators on both sides of the Atlantic, and the Pacific as well, joining the birds in the air.

Description: 

A critical challenge for this century is transitioning towards sustainable farming systems that simultaneously produce food and conserve wildlife. Yet conservation scientists and practitioners have traditionally fixated on protected areas and overlooked opportunities for conserving wildlife alongside us in working landscapes. Daniel uses ecological research to develop strategies for co-managing agriculture for bird conservation, crop production, and food-safety outcomes, both in the tropics and here in California. For this talk, Daniel will first discuss how climate change and habitat conversion are affecting tropical bird communities, and how shifts in farming practices may mitigate their combined impacts. Then, Daniel will shift his focus to California agricultural systems, where birds play multiple roles on farms, not only consuming crops and spreading foodborne diseases, but also consuming crop pests. Daniel will outline his lab’s work striving to find ways to manage California birds and take advantage of the benefits they can provide farmers, while minimizing harms to food production.
