I suppose some of you have already seen this news but it always good to hear some good news, second bird to reappear this year! Apparently the article should refer to the bird as a subspecies, rather than a separate species. Nevertheless....

Songbird Missing from Central Valley for 60 Years Reappears at San Joaquin River National Wildlife Refuge

                CALFED Funds Began Successful Restoration


A husky-voiced little songbird once common in Californiaâ??s Central Valley but not heard there for the last 60 years has reappeared on the San Joaquin River National Wildlife Refuge (NWR) west of Modesto.

The least Bellâ??s vireo (Vireo bellii pusillus) is a musical, chatty
bird. Some males have up to 15 different songs that finish with a
distinctive, â??cheedle, jeew.â?? That song was heard by bird counter Lynette
Lina along the banks of the San Joaquin River last Friday, who then
verified it with other bird monitors. On Tuesday, they were able to record
the birds to confirm the species.


     The sighting of a nesting pair of least Bellâ??s vireo occurred on the
refuge, a unit of the San Luis NWR Complex that was restored under the
CALFED program. The restoration began just three years ago and was
completed this spring. In that time, the former farm field has quickly
grown into a tangle of willows, blackberry, wild rose and other native
riverside plants, some already 30 feet high. It is reminiscent of the
original valley riverside habitat, and least Bellâ??s vireos soon found the
area, even though they havenâ??t nested in the Central Valley for 85 years.

     â??Hearing the least Bellâ??s vireo again demonstrates that a good
recovery plan, committed partners and resources to carry it out, can bring
many species back to life in areas where they seemed lost forever,â?? said
Steve Thompson, manager of the U.S. Fish and Wildlife Serviceâ??s
California-Nevada Operations Office.

     The wildlife refuges increasingly play a major role in the survival
and recovery of species.  The Aleutian Canada goose, for example, recovered
from the brink of extinction after it began wintering at the same San
Joaquin River refuge.

The least Bellâ??s vireo once was common from Red Bluff down throughout
the Central Valley and south into Baja California. But the removal of 90
per cent of the riparian habitat resulted in their steep decline. The last
time least Bellâ??s vireo breeding was confirmed in the valley was 1919. By
the 1940s birders could no longer hear them in the Valley. Exhaustive
searches for the bird in the 1970s and 1980s also came up empty-handed, and
biologists sadly concluded that the bird no longer nested in the valley.


      When the least Bellâ??s vireo was federally listed as endangered in
1986 only 300 pairs were left, all along small streams in Southern
California.

     This weekâ??s success is the outcome of a broad partnership involving
at least nine different organizations. CALFED spawned the effort in 1998
when it provided key funds to purchase an 800-acre farm owned by the late
Ed Hagemann. Many other agencies also contributed, among them the Natural
Resources Conservation Service, the Fish and Wildlife Service, the
California Resources Agency, the Army Corps of Engineers, and the Audubon
Society.

Three years ago, CALFED provided funds to the San Luis NWR to restore
a 164-acre section along the San Joaquin River where the least Bellâ??s vireo
now has nested. The restoration quickly filled in the farmed land with
classic Central Valley riparian habitat.


     The hands-on restoration work was an adaptive effort by three
conservation partners -- PRBO Conservation Science, River Partners and the
Endangered Species Restoration Program at CSU-Stanislaus. Each year they
made refinements to improve the quality of habitat being developed for
native bird and animal species. The process is closely monitored by PRBO
and ESRP, two wildlife organizations that work closely with state and
federal agencies to monitor special species.

Geoff Geupel of PRBO said the least Bellâ??s vireoâ??s return â??is a
success for CALFEDâ??s adaptive management approach to habitat restoration.â??
Learning from earlier restoration efforts, they planted more shrubby
understory and created a varied pattern of planting that mimics the natural
floodplain habitat. That created an area perfect for the least Bellâ??s
vireo -- dense shrubby understory.
