Birding Site Guide: Los Jilgueros Preserve in Fallbrook

At the edge of the town of Fallbrook is a small hiking park called the Los Jilgueros Preserve (eBird Hotspot here). The preserve follows a little creek alongside South Mission Rd. There is a pond or two and some drier upland areas and oaks.

It wouldn't be a birding destination in itself--it's smaller and is not known for unusual birds. But it's worth a stop for an hour or two if you are in the Fallbrook/Bonsal area.

Here are some birds I photographed in August 2016.

Western Meadowlark

A sunny yellow bird to brighten your rainy day! (Yes, even here in San Diego.)

Western Meadowlarks were once much more common than they are today. They are most common in native grasslands in North America--a habitat that is mostly gone. Such grasslands have been converted to strip malls, cattle ranches, and agricultural lands. As ground nesters, they need larger tracts of grasslands to hide their nests from coyotes, foxes, dogs, and cats, or being stepped on by cows and sheep. They can breed in most grasslands--it doesn't have to be native--as long as it is undisturbed from March to August. So fields of grain harvested in May or June as well as urbanization eliminates these pretty birds from former breeding areas.

In my lifetime I have seen these wonderful birds with their loud and joyously bubbly songs virtually eliminated as breeding birds from the Willamette Valley of western Oregon. I know this is true because even the European Starlings in western Oregon don't imitate Western Meadowlarks any more as they frequently did in the past--the last starlings to have heard meadowlarks have evidently all died of old age.

Meadowlarks can be found breeding still in the sagebrush and open ranch lands of eastern Oregon, and found in western Oregon in winter.

Here in San Diego they breed in some native grasslands in the foothill. Such is the case at the Ramona Grasslands Preserve where I photographed this bird. Admittedly, though, this bird is likely a visitor from elsewhere that had joined the large flocks gathered here for winter. Birds in the center of the continent migrate south into Mexico, but many more move west to winter in milder areas, such as coastal dunes and lowland pastures along the West Coast.

So even though they are less common now, you can still see them if you drive the roads through open farm country, especially in winter.

Index to my bird identification articles

I'm getting enough bird ID articles in this blog now, to warrant an index to find them. Plus I've written some other ID articles in various blogs over the years that I think are worth pointing out. As I add more identification articles to my Greg in San Diego blog, I'll add them to the top of the list.

Northern Mockingbirds at Borrego Springs

After Phainopeplas, Northern Mockingbirds are the second-most obvious birds at the Borrego Springs waste treatment ponds in winter. They are constantly singing and chasing through the mesquite there. And even if there are less than 10 total birds in the immediate area, they make themselves known by their loud calls, songs, antics, and penchant for perching up high and exposed.

Mockingbirds are pretty much found throughout San Diego County except the unbroken chaparral of the foothills and above 4000 feet in the higher mountains. Thus, the range in the county is cut in two by the north-south running mountains.

West of the mountains these are common resident birds in urban and agricultural areas throughout the coastal lowlands.

East of the mountains they breed widely throughout sage, scrub, and cactus habitats, as well as oases and towns. Interestingly, they breed noticeably less widely in the desert in drier years, retreating into desert towns then (Unitt, 2004). And they are less widespread in winter--concentrating near settlements and oases.

Another thing that is interesting about Mockingbirds is that they have a prolonged breeding season. They may breed twice, or sometimes thrice, in a single breeding season. Nests with eggs have been noted in California from late February to the beginning of September.
