Common Yellowthroat--Geothlypis trichas

The male Common Yellowthroat is easy to identify whether you see him or hear him. The male Common Yellowthroat has a Black mask with a white line edging the top of his mask, and a bright yellow throat and chest. The female and the immature males lack the black mask and are olive with a yellow throat and chest. Both have a whitish belly, pink legs. In spite of being wood warblers, Common Yellowthroats hold their tails at a wren-like angle.

Their call sounds like "wich-i-ty, wich-i-ty, wich-i-ty." Surprisingly easy to recognize. Although somewhat secretive, Common Yellowthroats are very curious, and will sometimes come out and look when they hear pishing or other sounds.

Like all wood warblers, Common Yellowthroats move fast through the foliage, flitting from one leaf to another. They are often hard to spot, but in spring, males like to fly up and sing perched on a high branch. Fast-moving and loud in spring describes the Common Yellowthroat. The Common Yellowthroat is found in tangled undergrowth near streams, wetlands, estuaries, and other bodies of water. They can also be found in agricultural fields. They are sometimes found in the tangled undergrowth somewhat far from water. There are about 14 subspecies of Common Yellowthroat warblers that vary only slightly in coloring and song.

Common Yellowthroats eat insects, their larval forms--including caterpillars--spiders, and occasional seeds. They are gleaners that pick insects off leaves and any part of the plant they can. They also have some other moves such as the sally-hover which is gleaning while hovering near a plant, and sally-strike which is catching flying food--in this case flycatching. Common Yellowthroats occasionally drop to the ground to forage.

Common Yellowthroats range from northern Canada and Southern Alaska south through southern Mexico. They are found from coast to coast and in every U.S. state except Hawaii.

Common Yellowthroats nest as they live, in the undergrowth. The nests are often low in the undergrowth or actually on the ground. Near water, they may be attached to plants like cattails or marsh grasses.

The Common Yellowthroat, like many birds, often lays a second batch of eggs. Unlike some other birds, the female starts her second nest when the first set of nestlings have fledged, but are still relying on the parents for food. She leaves the male to take care of the first fledglings as she begins their second family.

Since Brown-headed Cowbirds are ground-feeding birds, it is not surprising that these parasitic birds often lay their eggs in a nearby Common Yellowthroat nests. The fact that Common Yellowthroats are abundant gives the cowbirds plenty of places to lay their eggs. However, the Common Yellowthroat is no dummy and often notices the cowbird egg, either abandoning the nest or building over it to avoid incubating the intruder's egg.

The Common Yellowthroat may also push the cowbird egg out of its nest or may even abandon the nest altogether.

When there are few males in an area, a Common Yellowthroat male may take two mates.

Common Yellowthroats are really great little birds. I always feel I have accomplished something if I get off a fairly decent shot. So when you are out birding in Orange County, California don't forget to listen for the familiar call and check for the masked yellow warbler flitting through the branches or the reeds.

Where to find Common Yellowthroats in Orange County

In the parking lot area on PCH. On the path along PCH. Up on the mesa.

On the East side near Talbot Lake, on the West side near Lake Huntington, in the undergrowth on the path to Shipley Nature Center from the parking lot by Alice's. And in Shipley Nature Center.

In the undergrowth.

In the undeveloped part by the creek. Back behind the Playground. Also near the creek in the undergrowth bordering Campus.

In the butterfly garden and throughout the sanctuary.

All around the bay.

Look for places near wetlands, lakes, streams, and undergrowth. You will most likely hear "wichety, wichety, wichety" and if you are lucky will see a Common Yellowthroat in an Orange County Park or wildlife reserve.
