Cattle Egret--Bubulcus ibis--A Rare Bird

Cattle Egret courtesy of US Fish and Wildlife Service. The Cattle Egret is commonly described as appearing "hunched." You can see why above.

Although the Cattle Egret is not a water bird or shore bird, it can be found near ponds or in wetlands. It is a bird that primarily likes pastures and fields with cattle, other domestic and wild animals, tractors, and lawn mowers that stir up its favorite food--insects. They also will stand outside a fire and catch the insects escaping the fire. Cattle Egrets also eat spiders, frogs, earthworms, eggs, and small birds. They are more often seen in agricultural areas. I used to see them more in Orange County in the fields and in the freeway on ramps and off ramps in the grass. I have seen them within the last year in Riverside County out near San Jacinto.






You Tube Video of a Cattle Egret asleep--In breeding plumage.


Cattle Egrets are small white egrets with an orange bill, and black legs. In breeding plumage, they have a dusting of color from buff to orange. Although about the same size as a Snowy Egret, the Snowy has a more slender bill, yellow feet, and a black bill. So if it is small and a little stocky with an Orange Bill and no yellow feet, you can bet it is a Cattle Egret. The immature has a black bill--that is why location and build are important things to note.





You-Tube Video of Cattle Egret foraging in a Field.


It is not a native bird, but an immigrant. In the 1870s, it flew across from Africa and Asia to South America and moved northward. It reached the United States in the 1940s during World War II. It began breeding in California in 1979, though they reached the West Coast over a decade earlier. At the present time it has moved as far north as Canada and Alaska. I even saw it in Hawaii in the late 1990s. It was introduced there. Numbers vary greatly from year to year.






Cattle Egrets wait for escaping insects at the edge of a fire in Tanzania. Entitled "Fresh Toasted Bugs."



Cattle Egrets nest in colonies with other Cattle Egrets and other wading birds. They are monogamous for a season. They are the ultimate recyclers, and reuse nests. Nests are built of plant materials. The nest is a competitive place with the chicks vying for food with one another.



So when you are out birding Orange County and see a small white egret, check the bill and the build. Especially if it is in a field. You just might get lucky and see a Cattle Egret in Orange County.

Belding's Savannah Sparrow--Passerculus sandwichensis beldingi


Belding Savannah Sparrow on the railing of the Footbridge at Bolsa Chica overlooking the pickle weed.


The Belding Savannah Sparrow is an an endangered subspecies in the State of California. It is one of the 17 subspecies of the Savannah Sparrow. Six of those subspecies live at least part of the year in wetlands such as salt marshes. The Belding Savannah Sparrow is a resident of Orange County and other California counties, and does not migrate.





Belding Savannah Sparrow near the pickle weed.



The Belding Savannah Sparrow lives almost exclusively in and near the pickle weed. Look for this little streaked sparrow flitting around in the pickle weed and nearby environs. It pops up and down and sits on top of the pickle weed and posts and on the foot bridge at Bolsa Chica. A cute and fast little bird. This bird is one of the endangered birds in Orange County. It is endangered in Orange County and State-wide due to loss of habitat.



Belding Savannah Sparrow down in the mud.

The Belding Savannah Sparrow is a little brown-and-white streaked sparrow with a yellow eyebrow stripe. Males and females are similar.



Belding Savannah Sparrow in its favorite habitat--the pickle weed at Bolsa Chica.

Belding Savannah Sparrow eat seeds, insects and their larvae, spiders, and snails. There are lots of these in the pickle weed. They also eat berries, small crustaceans and mollusks. Lots of the last two in the mud. They forage mainly on the ground.




Belding Savannah Sparrow on the railing of the Footbridge at Bolsa Chica.

The female builds the nest. The Belding Savannah Sparrow builds a grass-lined nest on the ground concealed under the pickle weed or other low plants. Sometimes, the birds create a tunnel through the pickle weed or grass that leads to the nest. Generally monogamous.



Belding Savannah Sparrow on the railing of the Footbridge at Bolsa Chica.

If you want to see the Belding Savannah Sparrow, the best place to see it is at Bolsa Chica Ecological Reserve. Stand on the bridge and watch until they start popping up and you will see a true wetlands bird. Birding in Orange County is fun when you stake out the pickle weed. It is so satisfying to wait for a bird and finally see it come out in the open. Try it and see if you don't add the Belding Savannah Sparrow to your birding life list.
