Lights Out For Birds

ByRyan Nakano

Lights Out For Birds

About one billion birds migrate over the Bay Area every year as they journey from wintering grounds to breeding grounds, and back. Artificial lights from our cities and towns cause birds to collide with buildings, veer off course, and tire out, making them vulnerable to predators, starvation, and exhaustion. Most bird species migrate at night, including songbirds and hummingbirds.

But this is a problem we can solve! You can help by turning off, dimming, or redirecting lights at night during migration periods in spring (February through May) and fall (August through October). Reach out to your buildings, businesses, and workplaces to ask them to do the same.

These easy steps will make a difference:

  • Exterior Lights:
  • Turn off any unnecessary lighting
  • Install motion sensors
  • Down-shield lights wherever possible

Interior Lights:

  • Reduce or turn off lobby and atrium lighting
  • Turn off lights when rooms are not in use
  • Pull blinds or drapes for rooms in use

Just under one billion birds are killed by building collisions in the United States each year. Artificial lighting at night has been shown to increase the rate of collision with glass windows. Birds are attracted to the lights, and disoriented, causing them to collide with the illuminated surfaces. Turning off lights will reduce the number of collisions with buildings and glass.

Most collisions occur on homes and the first four stories of buildings. In addition to turning off lights, you can ensure your windows are bird safe and prevent collisions with window treatments, tested by the American Bird Conservancy.

Birds use natural night light sources such as the stars and moon to navigate at night. When dense urban and suburban areas are lit up, the combined effect creates a landscape level illumination called “skyglow.” Skyglow causes birds to change their migratory pathways, curving towards the brightly illuminated areas. This often means birds are traveling further, expending more energy and therefore risking exhaustion and starvation.

Additionally, skyglow has been proven to cause birds to stopover more frequently than they would naturally. Rather than traveling as far as they can go in a single night, they end up stopping early and landing in our cities and towns. When birds stopover in urban areas, they are in danger of the other threats cities pose such as collision with buildings and cars, predation by outdoor cats, pollution, and difficulty finding food.

Burrowing Owls

Burrowing Owls

Burrowing Owls/Patricia Corapi

The Western Burrowing Owl (Athene cunicularia) is a small, ground-dwelling species of owl found in North and South America. Native to open landscapes with low vegetation such as grasslands, prairies, and deserts, it nests in underground burrows abandoned by other animals.1 Southern populations of the Burrowing Owl are year-round residents; northern populations are migratory and fly south to overwinter in warmer conditions.  

Human development-driven habitat loss coupled with population declines of burrowing mammals poses a serious threat to Burrowing Owl populations. Total Burrowing Owl numbers have dropped by at least 33% since 1965. The decline has been particularly steep in California, where numbers have fallen by 60% and coastal breeding populations have been  nearly extirpated.2 As a result, the Burrowing Owl has recently been designated as a candidate species for the threatened and endangered list under the California Endangered Species Act (CESA). As a candidate species, Burrowing Owls have the full protection of CESA while the listing process is finalized.

Before extensive urban development, the San Francisco Bay Area’s coastal prairies and grassland provided habitat for both resident and migratory populations of Burrowing Owls. Now, however, the region hosts fewer than 25 resident breeding pairs and  a dwindling number of overwintering birds.3 Protecting the remaining habitat is critical to sustaining their populations and preventing local extinction in the Bay Area.

Cesar Chavez Park in Berkeley has remained a Burrowing Owl overwintering ground for over three decades. In 2011, a fence was erected around the Burrowing Owl habitat to protect the owls from human disturbance. Burrowing owls are most likely to nest on open land with little to no visual obstruction4, and the low height and minimalistic design of the fence minimizes habitat disturbance to the owls while serving as a symbolic reminder for parkgoers – especially dog walkers – to be mindful of Burrowing Owl grounds. Although a more robust fence could offer more protection against people and their pets, it would inadvertently compromise Burrowing Owl safety by providing a perching area for known avian predators5 and obstructing the owls’ line of sight, which could discourage them from overwintering in Cesar Chavez Park.

Golden Gate Bird Alliance has worked with the Berkeley Recreation, Parks and Waterfront Department since 2009 to maintain quality habitat for Burrowing Owls at Cesar Chavez and to monitor Burrowing Owl populations along the Berkeley waterfront. Our data, collected with the help of our volunteer monitoring program, has helped us better understand local Burrowing Owl needs and raise public awareness about their conservation.…

Dog Management in the GGNRA

Dog Management in the GGNRA

ByGGBA

Golden Gate Bird Alliance has long advocated for reasonable management of on- and off-leash dogs in the Golden Gate National Recreation Area (GGNRA). Current dog-related recreation is managed under the 1979 Pet Policy, which is not a legal regulation and which fails to protect wildlife, habitat, and park visitors.

In 2013, the National Park Service released its revised proposed Dog Management Rule and Supplemental Environmental Impact Statement (SEIS) to manage dog-related recreation in the GGNRA. The proposed rule is the biggest accommodation for on- and off-leash dogs in the National Park System.

The proposed Rule allows for four off-leash dog areas and 21 miles of on-leash dog recreation in the San Francisco portion of the GGNRA. No other National Park allow off-leash dogs, and most limit on-leash dogs to a few paved trails.

Golden Gate Bird Alliance supports better regulation of dogs in the GGNRA. While we believe that the proposed regulation is a good first step, the proposed rule does not adequately protect park resources.

We encourage you to share your opinions and experiences with the National Park Service. Click here to file an online comment. The NPS is accepting comments through February 18, 2014.

In our comments, we will emphasize the following points: 

  • The GGNRA should provide more opportunities for visitors to recreate in the GGNRA in San Francisco without interacting with dogs.  Currently, the Preferred Alternatives only provide a few areas where visitors, including those with small children, may go without having to interact with dogs. Many parents and grandparents have told us they will not take children to areas where there are many off-leash dogs. This is not fair to community members that have a right to enjoy the park without fear or discomfort due to the presence of dogs. 
  • Off-leash areas should be well defined by a physical barrier. Park visitors should have the choice of interacting with dogs during their park experience, rather than having the choice made for them. Clearly defined on- and off-leash areas will allow dog owners and other visitors to know where dog-related recreation is appropriate. It will also better protect sensitive wildlife and habitat resources, reduce conflicts with other users, and allow for less controversial enforcement of the new rules. 
  • The SEIS fails to establish that “voice control” is a valid method of controlling off-leash dogs.

Oakland’s bird-safe building rules in the SF Chronicle

ByGGBA

The S.F. Chronicle ran a nice story on July 8th on Oakland’s new bird-safe building rules, which Golden Gate Bird Alliance suggested and helped develop.

You can read the Chronicle story here.

Or click here for our blog post on the new rules (including a link to the rules themselves), which make Oakland the third major city in North America to adopt such standards.  The other two cities are Toronto and San Francisco.

Thank you, Oakland! And thank you to GGBA staffer Noreen Weeden who worked with Oakland city planners on drafting the rules.…

Sharp Park Restoration in San Francisco – Mayor Vetoes

ByGGBA

On December 19, 2011 San Francisco Mayor Edwin Lee vetoed proposed legislation to restore Sharp Park.

This legislation which was sponsored by Supervisor Avalos was supported by 36 community and environmental groups and approved by the Board of Supervisors.

Read Bay Citizen coverage of this veto : Lee Sides with Golfers

Golden Gate Bird Alliance supports legislation to restore the wetlands and Sharp Park and to transfer the long term management of the Park to the Golden Gate National Recreation Area.   This is the best solution in terms of the endangered species protection while meeting the current recreational needs of San Franciscans. 

1) Today send an email or call each of the supervisors on the City Operations and Neighborhood Services Committee:

Supervisor John Avalos email John.Avalos@sfgov (415) 554-6975
Supervisor Eric Mar email Eric.L.Mar@sfgov.org (415) 554-7410
Supervisor Sean Elsbernd email Sean.Elsbernd@sfgov.org (415) 554-6516
 
2) Attend the hearing on Monday, December 5, 2011 starts at 10:00 a.m.
SF City Hall, City Operations & Neighborhood Services Committee – Legislative Chamber Room 250
 

Why restore the Sharp Park wetlands and create a new public park in San Francisco?
·    To protect, recover, and ensure the long term survival of two federally-listed endangered species, the San Francisco garter and the California red-legged frog in the area.
·     Since 2004 Sharp Park has lost an average of $162,000 each year on a park that continues to inflict harm on wildlife.
·     Closing the course will save additional millions of dollars by eliminating the obligation for costly infrastructure projects needed to protect the park against sea level rise, costs from failing to comply with federal environmental laws.
·      The money saved would allow San Francisco to improve currently underfunded neighborhood parks, community centers, education programs, local jobs, and/or social services within the community. 
·       Resources for more popular recreational activities, such as hiking and biking, would benefit more people, rather than investing additional money to improve this golf course.  Sharp Park Golf Course has received failing reviews in nearly every category the National Golf Foundation measures.
 
What will the Sharp Park legislation do?
·      The legislation directs the Recreation & Park Department to partner and create a long-term management agreement with the National Park Service including a financial roadmap, and address urgent environmental and infrastructure needs. ·        Sharp Park would be transformed from golf to a new public park emphasizing trail-based recreation and would be managed by the National Park Service.…
