Is a Drone disturbing Wildlife?

What you can do if you see a drone disturbing wildlife:

  • Contact your local police non-emergency number.
  • Contact Department of Fish and Game by using the CalTIP program
  • Get the license plate number of the drone pilot's vehicle.
  • Obtain a photo or video of the pilot using the drone in a manner, which is disturbing the birds. However, do not put yourself in danger while doing this. Do not confront the pilot.

Foster City Canada Goose Mitigation Plan

The Sequoia Audubon Society Board of Directors is aware of the plans by Foster City to reduce the population of Canada geese in the City's parks, open spaces, and waterways by obtaining a permit to allow culling up to 100 geese by lethal means. The Board's position is that lethal means should not be implemented until non-lethal means have been fully utilized and given time to work. We recognize that the impacts of excessive numbers of Canada geese are significant and action is warranted. However, measures such as habitat modification, hazing, and addling of eggs have been proven effective with proper resources.

The Board's position was provided in a public comment session during a meeting of the City Council considering whether to continue pursuit of applications for the permits needed for lethal action. Unfortunately, the City Council voted to continue with the application process. That may not be the end of the opportunity to express opposition to the lethal measures. If the permits are issued, Foster City will still need to enter into an agreement with a specialized contractor to carry out the culling. This may present a fresh opportunity for the community to let its opposition to the lethal measures be known. We urge anyone interested in the subject to monitor the Foster City website for the latest information.


Origins of the Crystal Springs Christmas Bird Count

CBC circle
CBC Circle as defined by Jim Rigby

The Crystal Spring Christmas Bird Count (CBC) is among the highlights of the yearly avian calendar for San Mateo County birders. Sequoia Audubon's website boasts how "the Crystal Springs CBC is one of the top counts in the country, consistently placing in the top 10 in terms of number of species seen." The count circle is based around the Crystal Springs watershed, but its 15-mile diameter encompasses the mud flats of Foster City, suburban oases and canals, the oak woodlands of the foothills, mixed redwood forests along Skyline, and into Half Moon Bay and the Pacific Ocean. The spectacular habitat diversity in this capacious bay-to-sea circle sets the table for countdown dinners stuffed with eager anticipation and gaudy total numbers. So how did we get this lucky, to inherit the most deftly-designed circle in the nation? The story is a tad older than Sequoia Audubon itself!

Learn Bird Sounds and Benefit
Sequoia Audubon Society!

Ever wish you knew how to identify birds by ear? It's one of the most essential birding skills, but one of the hardest to learn. Some folks from Seattle's Audubon chapter set out to make learning bird sounds truly accessible to everyone.

The result is Larkwire: a game-based learning system that uses cognitive techniques to make it easier to learn and remember bird sounds. Combining quiz games, an extensive sound library, and tips from renowned birdsong expert Michael O'Brien, Larkwire makes the learning process not only much easier but fun. Customizable levels from beginner to advanced invite both the backyard birder and the serious student to play and learn.

The company behind Larkwire is a social venture whose mission is not only to teach birdsong; a minimum of ten percent of all proceeds go to support conservation.

Sequoia Audubon Society has joined their affiliate program; enter our code when you purchase and we'll receive 20% of the purchase price! Our code: SEQAUD

Larkwire is now available as a native app
in the Apple App Store.
