The California That Was: A Day in the San Luis National Wildlife Refuge

I've spent a good part of the last few months blogging about the "Hawai'i That Was", in which I have been exploring the bits and pieces of the original islands that existed before European/American incursion. I will even finish the series before long, but in the meantime I've been keeping up with the new semester (already a third of the way over), and the fall field trips. I had a break last Saturday and Mrs. Geotripper and I headed south to see if any of the migratory birds had arrived at our local refuges.

The first refuge, the Bear Creek unit of the San Luis National Wildlife Refuge was sort of a bust, as no water had been allocated to the pools there, but the Tule Elk autotour a little farther south afforded some neat photo opportunities. A huge Tule Elk buck rose out of the grassland, and I was suddenly reminded that there is a "California That Was" as well. I live in a huge prairie, the Great Valley of California, and even though most of it (95%) has been consumed by agricultural and urban development, there are still some pieces left here and there where one can be reminded of what a treasure this valley truly is (or was).

Can you see why I took this picture?

The prairie grasslands extended for four hundred miles from present day Bakersfield to Redding, and the valley averages forty or fifty miles across. Although it receives rainfall equivalent to a desert in the southern portion, rivers draining the Sierra Nevada provided plentiful water, so much so that a large part of the south valley was covered by shallow lakes (Buena Vista and Tulare). Those lakes disappeared during the last two centuries as streams were diverted for agricultural development.

The valley supported a rich ecosystem that included numerous grazing species such as the Tule Elk, deer, and pronghorn antelope, and predators that included wolves, coyotes, mountain lions, and Grizzly Bears. Many of them are gone, but we were privileged to see the Tule Elk herd and a well camouflaged deer that made its way to the Salt Slough for a drink.

More than anything else, the "California That Was" was bird country. Millions upon millions of migratory geese, cranes, and ducks called the valley home during the winter months when the northlands were covered with ice and snow. The lakes, rivers, and wetlands provided food and shelter for the tired migrants. Although far less land is available to them today, hundreds of thousands of birds still spend the winter here, and that's what we were looking for on Saturday. We heard that some Sandhill Cranes had already arrived and we wanted to have a look.

Hundreds of them had indeed arrived, but we were surprised by the number of egrets present in the refuge. It's strange how such birds can be clumsy looking and graceful at the same time.

The California prairie is perhaps the most altered landscape on planet Earth. It's nice to know that there are dedicated groups of people working to maintain some small corners of the valley for the birds and other wildlife. It's a real privilege to have a chance to see what was once here.

The Birds of My Neighborhood: Geotripper Explores the Home Base

These pictures will be familiar to my Facebook friends who have been subjected to several weeks of wintertime explorations of my neighborhood looking for our local bird species. I've always liked birds, but I've lacked a camera with sufficient zoom to capture them easily, and I am pretty bad at remembering names and species. I've been surprised at how many different species can be seen during short walks around the block and through the nearby cow pasture (although I shouldn't be; we live in prime wintertime bird habitat).

The first, and one of my favorite recent pictures, is a Western Scrub Jay (Aphelocoma californica) making a meal out of a pecan. The scrub jays are obnoxious and raucous, and at constant war with our cat in the backyard, but they are also a bright splash of color, and are one of my favorites.

The Snowy Egret (Egretta thula) is a fairly common wetlands inhabitant in our area. They are one of the most graceful birds I see on a regular basis, standing very still will getting ready to stab at fish or amphibians in shallow water (like they did when they got the goldfish in my pond...).

I keep a feeder in the backyard, and it attracts three or four varieties of finches, including the House Finch (Haemorhous mexicanus), the Goldfinch (Carduelis tristis), and the Lesser Goldfinch (Carduelis psaltria). They like their sunflower and nyjer seeds and they are quite vocal in their complaints when I let the feeders go too low.

I thought the gray bird in the picture below was a mockingbird from a distance, but some of my facebook experts suggest that it is a Western Kingbird (Tyrannus verticalis). I am open to being corrected in this identification.

True to the season, here are two doves, but they aren't turtle doves. I was told (and agree) that these are Eurasian Collared Doves (Streptopelia decaocto). It is an relatively recent invasive species that I have constantly mistaken for Mourning Doves.

On a brief foray along the Tuolumne River near La Grange we found an American Kestrel (Falco sparverius) watching for a meal from a telephone pole.

For ten years I've been trying to catch a photo of a Yellow-billed Magpie (Pica nuttalli), a species unique to California (it is a cousin to the Black-billed Magpie found in much of the rest of the country). They have been very shy when I come around with a camera, but one hung around for a moment before flying away the other day. They've been decimated by the West Nile Virus.

I am familiar with the story of how European Starlings (Sturnus vulgaris) arrived in America to become a pest (it was a Shakespeare lover of all people), but I had never noticed them around my neighborhood until I started walking a few weeks ago.

The Killdeer (Charadrius vociferus) is a widespread species found all over the Americas, but it holds kind of a special place in our valley. We chose it to be part of our banners and symbols for the new Science Community Center at Modesto Junior College. As if to play the part, a Killdeer set up a nest on the vacant lot north of our building that will eventually become our Outdoor Nature Laboratory. I often hear them when I walk around the campus.

 There must have been a dozen of them running about the cow pasture a few blocks from my house.

The biggest surprise in my recent walks was the drumming of a woodpecker. I've never noticed any near my house, but walking under a telephone I heard one pecking away.

A bit of research suggested that it might be a Nuttall's Woodpecker (Picoides nuttallii). It's the second kind I've seen in the region so far (the other is the Acorn Woodpecker, farther up in the mountains).

The small bird wandering in the grassland appears to me to be an American Pipit (Anthus rubescens), but I await your confirmation. They hide well, so I've never noticed them before.

The other of many pleasant surprises has been the spotting of some Western Bluebirds (Sialia mexicana) in the trees around the cow pasture. I don't think they've visited our bird feeders.

The pictures I took the other day show a brightly colored male (above), and a slightly more drab female (below). I'd like to see more of them!

I've enjoyed paying more attention to our local bird life, and look forward to adding more of them during my travels. Once again, have a wonderful Christmas and restful holiday!
