Bird Habitat at River Garden Farms

Near the north edge of Yolo County, a little-known birding hotspot lies along County Road 98A where it meets State Highway 45.  A grove of big valley oaks along the highway tapers into a line of trees, mainly along the east side of the road, with a wide drainage canal

Conservation Ranching at Bobcat Ranch

Why does Audubon California support cattle ranching, when some believe that cattle production and beef consumption are bad for the planet? For an answer, look no further than the hills northwest of Winters, to Bobcat Ranch.  Although it may look like an ordinary cattle ranch, its grazing program aims to improve

Nest Box Reports for 2021

Submitted by Sonjia Shelly, YAS Board In early 2020, the Yolo Audubon Society board was approached by two local organizations (Friends of North Davis Channel and Woodland Regional Preserve) to fund and install song bird nest boxes in their respective areas. The YAS board provided the funding for needed materials,

Improvements at North Regional Pond in Woodland

Combined with the wastewater treatment ponds next door, North Regional Pond is a top birding destination in Yolo County. With 210 species recorded in eBird*, it is one of only eight sites in Yolo with over two hundred kinds of birds. In the last year it has offered us rarities

The tricolored blackbird—still in peril

Nearly all of the world’s tricolored blackbirds nest in the Central Valley and nearby foothills.  Yolo County has been home to several breeding colonies in recent years, totaling twenty thousand or so adults, and often with large numbers in winter as well.  Thus, Yolo Audubon has an unusually direct stake

A Century of Changing Birdlife in the Central Valley

From 1912 to 1923, Joseph Grinnell and fellow ornithologists at UC Berkeley surveyed birdlife in spring and summer at forty-one stations in the Central Valley, producing a baseline list of the breeding birds of the region. One hundred years later, another UC Berkeley group revisited the same stations at the

A network of nest boxes for Yolo County songbirds

Placement of nest boxes for small songbirds along the Putah Creek corridor has had a history of success. Birds fledge young from them in large numbers, year after year (see this column, February 2017). A recent string of boxes in the heart of Davis has been likewise well received by

Effects of Recent Wildfires on Yolo County Birds

The complex of wildfires in late summer that burned large swathes of Yolo, Solano, Napa and other counties devoured oak woodland, forest and chaparral indiscriminately. Wanting a sense of the effects of those fires on the birds of the area, Steve Hampton and I pored over reports from birders around the

Volunteer Opportunity: Phenology Surveys at Bobcat Ranch

Text by Joe Zinkl, Phenology Survey Coordinator Yolo Audubon members have been conducting a phenology survey at Audubon California’s Bobcat Ranch for over four years. The study is conducted in cooperation with the National Phenology Network. All data collected by our surveyors is sent to NPN. What is phenology exactly?

Progress on the Lower Elkhorn Basin Levee Setback

The Sacramento Bypass Wildlife Area (along County Road 126, off River Road just north of the city of West Sacramento) is an excellent birding spot, with 197 species reported on eBird. This large bird list reflects the presence a strip of forest at the foot of the north levee of

Birding by Ear

In most Yolo County landscapes, birds are usually hidden from view, while fly-overs are often too distant to be identified by eye. And some birds fly by night. In all those instances, birding by ear is essential for knowing who they are, and thus essential for better understanding of the

Safe Harbor Agreements in Yolo County

In the field of endangered species management, the term Safe Harbor refers to agreements with the US Fish and Wildlife Service by which a landowner voluntarily improves or expands habitat for a species and, sometime later, can decide to return the property to its original condition without penalty. The aim

Near the north edge of Yolo County, a little-known birding hotspot lies along County Road 98A where it meets State Highway 45.  A grove of big valley oaks along the highway tapers into a line of trees, mainly along the east side of the road, with a wide drainage canal downslope along the west side.  The combination of oaks, permanent water and farmland edge, plus having the Sacramento River as a migration corridor just across the levee, makes for decent birding.  125 species have been recorded on eBird, including  an American redstart in fall 2018.

Now the birding is set to get much better.  Audubon California, in partnership with the landowner, River Garden Farms, has proposed to restore forest and wetland habitat along Road 98A.  The idea is to link the oak grove along the river with permanently protected wetlands two miles to the south at Roosevelt Ranch.  The first phase of restoration will put nineteen acres of trees and shrubs along a mile and a half of both sides of the road.  A second phase would create a wider and more nearly natural wetland between the road and the canal. Staff of the Wildlife Conservation Board have recommended approval of the first phase.  The Board will vote on the project in early or mid-2022.

This is indeed good news.  On the other hand, the WCB did not approve the proposal to improve shorebird and land-bird habitat at North Regional Pond in Woodland, described in this column in May.  The proponent, the Yolo Resource Conservation District, will continue to seek funds for what I regard as a sorely needed project.  Small amounts of money from the US Fish and Wildlife Service and the Yocha Dehe tribe will likely allow some planting there this fall or winter.

The contact person for the project at River Garden Farms is Khara Strum of Audubon California, kstrum@audubon.org.
