Beauty is Everywhere

I have been passionate about photography ever since my high school days in Hillsboro, Oregon. Back then, it was all about sports and news events. These days, I love photographing birds in their environment. It's my passion in life.

On the Pickleweed Trail: Picture of the Day

Mule Deer on the Pickleweed Trail in Martinez

Oh, deer...sometimes, when you're looking for an Anna's Hummingbird, you find a Mule Deer instead. A nice surprise on the Pickleweed Trail in Martinez. There were actually two of them, but the other one ran down the trail, while this one stayed around for a couple of quick pics :)

Bird of the Week: Canada Goose

The Canada goose (Branta canadensis) is an iconic North American waterfowl easily identified by its black head and neck, white "chinstrap," and large brown body. Once a symbol of the wilderness, these birds have become highly adaptable to human-altered environments like city parks and golf courses.

Key Biological Facts

  • Life History: They typically mate for life, beginning at age two or three, and can live 10 to 24 years in the wild.
  • Diet: Primarily herbivorous, they graze on grasses, grains, and aquatic plants.
  • Migration: Known for their distinctive V-shaped flight formations, which help reduce wind resistance and improve communication during long journeys.
  • Subspecies: There are seven recognized subspecies, ranging from the Giant Canada goose (up to 20 lbs) to smaller varieties.
  • Cackling Goose: In 2004, the four smallest former subspecies were reclassified into a separate species called the Cackling Goose. 

Behavior and Human Interaction

  • Aggression: Canada geese are notoriously protective of their nests and young (goslings). They will hiss, charge, and slap with their wings if they feel threatened.
  • Urban Residents: Many populations are now "resident," meaning they no longer migrate and stay in urban areas year-round where food is plentiful and predators are few.
  • Legal Protection: They are protected under the Migratory Bird Treaty Act, making it illegal to harm them, their eggs, or their nests without specific federal permits.

Radke Martinez Regional Shoreline Park

I love my morning photo walks at Radke Martinez Regional Shoreline Park.  Located just off the Carquinez Strait in Martinez, it is a hidden gem in the vast system of waterways in the California Delta. It is also a great place for birding, with a variety of birds year-round, including egrets, herons, ducks, sparrows, wrens, turkey vultures and osprey.

Pacheco Marsh

Pacheco Marsh is the latest restoration and public access project from the John Muir Land Trust. It is a great place for a nice, peaceful walk along the marshlands of the Carquinez Strait. There are a variety of birds, including egrets, hawks, ducks, marsh wrens, finches, sparrows and White-tailed Kites.

Acorn Woodpecker, Mt. Wanda, Birds of the California Delta

Mt. Wanda

Part of the John Muir Land Trust, Mt. Wanda is a great place to explore nature and a cool place for birding. If you love Acorn Woodpeckers, this is definitely the place for you. They can be seen frequently, either in flight or hoarding acorns on one of the granary trees in the area. Their unique “waka-waka” calls can be heard quite often along the trail systems of Mt. Wanda.
