This stocky little songbird is similar in coloring to the more slender Mockingbird. Unlike the Mockingbird, Loggerhead Shrike sports a black mask over its eyes. Because it has songbird feet, not talons, it secures its the prey by thorns and forked branches. Then the shrike uses its strong bill to tear up its prey. The Loggerhead Shrike's songs sound like moderately musical tweets, whistles, and buzzy, loud calls. It is about the size of an American Robin. It can be differentiated from the Mockingbird by its stocky build, its mask, dark, hooked bill, darker wings in flight, and dark eyes. The immature Loggerhead Shrike is duller and has very light barring across the back and the chest. The Mockingbird has yellow eyes. The Loggerhead Shrike is similar to the larger Northern Shrike which is rarely--if ever-- seen in Orange County. I have searched the Orange County Rare Bird Alert and have not found one record of a Northern Shrike in Orange County.

Loggerhead Shrikes nest in Canada, Washington and south to California, Wisconsin, Minnesota, Michigan, Maryland, and Florida. The breeding range looks spotty on the map. Loggerhead Shrikes return to breeding grounds starting in February and continue to arrive through May. By August, they are heading back to their wintering grounds. In Orange County, although we have Loggerhead Shrikes year round, they are almost rare.

Populations of Loggerhead Shrikes have declined 71% in the last 40 years. Since I started birding in 1982, I have noticed the decline in Orange County. Pesticides are one factor. In addition, current farming practices clear fields of trees so large machinery can be used, and thus the Loggerhead Shrike's perching trees and shrubs in agricultural fields are disappearing. They like to catch insects flushed out by farm machinery, but Orange County farmland of any kind is disappearing fast due to its conversion to housing subdivisions. Loggerhead Shrikes need land and that is exactly what is shrinking as we all crowd in to areas that used to be farmland. Check out Riverside County near Hemet if you want to see farmland disappearing in Southern California. It is hard to find Loggerhead Shrikes in Orange County with its housing-and-mall sprawl. There was a time when on the way to work I would pass miles and miles of farmland and stop at the Irvine Ranch Market for fruits and vegetables. No more. I did see a lone Loggerhead Shrike just recently at Bolsa Chica Ecological Reserve though. It was great to see the gray-and-black masked song bird sitting on a post. Interestingly, he was near a dead bush that may have had thorns. I haven't see the masked bird in a long time.

The best thing to do if you want to see a Loggerhead Shrike in Orange County is to look in areas where Loggerhead Shrikes have been seen and in areas that provide the low grassland habitat with a few perches that would attract them. A thorny bush or two nearby wouldn't hurt. So when you are out birding in Orange County, keep an eye out for this masked bird. The Loggerhead Shrike may be perched on a post, dead tree, or fence near you.
