Status of the Tricolored Blackbird and Yellow-billed Magpie

Tricolored Blackbird by David Bogener

This month Dan Airola will provide recent status information on the Tricolored Blackbird and Yellow-billed Magpie, two Central Valley species that have declined substantially in recent years. Blackbird population loss has resulted from habitat loss, nest destruction during agricultural harvest, and loss of insect prey due to insecticide use. The successful proposal to list the species under the state Endangered Species Act sparked research and conservation programs. Dan recounts this recent history and the successful efforts that have resulted in modest but important population increase. The population of the state-endemic Yellow-billed Magpie declined by over 80% in California since the arrival of West Nile virus in the early 2000’s, and did not develop resistance, unlike some other species. Dan’s recent studies reveal key habitat relationships and an apparent incipient recovery in the sizable urban Sacramento population.

Dan Airola is a Wildlife Biologist and Ornithologist who has worked for over 40 years in research and conservation of at-risk species birds in Northern California. In addition to long-term research on the tricolor and magpie, Dan maintains a 30-year study of Sacramento’s Purple Martins and has also studied Swainson’s Hawks, Turkey Vultures, Osprey, fire-adapted forest species, migrant songbirds, and diving ducks. Dan also serves the Central Valley Bird Club as a Director, Conservation Chair, and editor of the journal Central Valley Birds.

Wintu Audubon Society is inviting you to a scheduled Zoom meeting.

Nur Pon Open Space

By on August 29, 2023 in

Nashville Warbler

Join Wintu Audubon Society for a bird walk around Nur Pon on Saturday, September 23 at 8:00 am. Nur Pon, or “Salmon Run” in the Wintu language, was once known as Henderson Open Space before the City of Redding and numerous other agencies began a restoration project that established a side channel along the Sacramento River for salmon spawning. The parkland has been cleared of debris, much of the nonnative vegetation has been removed, the area fenced and secured, and more restoration work is underway. Wintu Audubon Education Chair Tricia Ford will lead the easy walk of approximately 1.5 miles, taking about three hours to identify the birds of river and oak woodland. Binoculars will be available for loan. Hiking boots are recommended for the river cobble. Bring water and a snack. Nur Pon is off Hartnell Avenue at the intersection of Parkview Avenue and Henderson Road on the east side of the river. Park behind the Cobblestone Shopping Center (once the site of Raley’s Supermarket) inside the wrought iron fence.
