Yellow-headed birds are a common sight in Southern California, known for their bright plumage and loud calls. There are a few different species of yellow-headed birds found in the region, each with their own distinct features and behaviors.
Yellow-headed Blackbird
One of the most recognizable yellow-headed birds in Southern California is the yellow-headed blackbird (Xanthocephalus xanthocephalus). As their name suggests, these birds have a striking yellow head and breast, contrasting with an otherwise all-black body. Their yellow plumage is brighter in males than females.
Yellow-headed blackbirds are medium-sized songbirds, reaching lengths of 8.3-10.2 inches and weighing 2.1-3.4 ounces. Their bill is thick and conical shaped. They have a long tail and short rounded wings.
This species breeds in wetlands across western North America. They can be seen around marshes, ponds, and shorelines in Southern California. Yellow-headed blackbirds make nests out of wetland plants concealed in dense vegetation. They lay 3-5 eggs per clutch from April to July.
These birds feed on insects, spiders, seeds and grains. They often forage on the ground in large flocks. Their diet consists mainly of insects like dragonflies, damselflies, and grasshoppers during the breeding season. The rest of the year they will eat more plant material like seeds from grasses and weeds.
Yellow-headed blackbirds produce a wide array of calls described as conks, squeaks, croaks and chatterings. Their familiar song is a melodious mixture of wheezes, pops, and whistles. Males sing to defend territories or attract mates.
Western Meadowlark
Another common yellow-headed bird in the region is the western meadowlark (Sturnella neglecta). These plump songbirds have a yellow face, throat, and chest with brown plumage on their back and wings. They measure 6.3-10.2 inches in length.
Western meadowlarks can be seen in grasslands, pastures, meadows, and other open areas. They make cup-shaped nests on the ground hidden in dense vegetation. Females lay 3-7 eggs that hatch after 13-16 days. This species sometimes interbreeds with the eastern meadowlark where their ranges overlap.
Their diet consists mainly of insects like beetles, grasshoppers, caterpillars, and ants. They supplement this with seeds, berries, and grains. Western meadowlarks forage while walking along the ground in short vegetation.
These birds have a beautiful flute-like song described as a series of high-low pitched notes and a buzzy ending. Males sing to defend territories and attract mates. Their call is a short pumping sound.
Yellow Warbler
Yellow warblers (Setophaga petechia) are small songbirds with yellow plumage that migrate through Southern California each spring and summer. Males have reddish streaks on their breast and sides. Females lack streaking and are more olive above.
This warbler reaches lengths of 4.7-5.5 inches and weighs just 0.3 ounces. They have a thin pointed bill suited for catching insects. Their wings are long and rounded.
Yellow warblers breed throughout North America near wetlands, streams, thickets and woodland edges. In Southern California they can be seen in parks, yards and other semi-open areas with trees and shrubs. They make neat cup-shaped nests out of plant materials.
Their diet is almost entirely insects like beetles, caterpillars, moths, ants, wasps, and spiders. They glean insects while flitting through foliage. This agile warbler sometimes catches insects mid-air by sallying out from a perch.
Males sing a sweet whistled song often described as “sweet-sweet-I’m-so-sweet.” Their call is a distinctive chip note. Yellow warblers sing to establish territories and attract mates during the breeding season.
Bullock’s Oriole
Bullock’s orioles (Icterus bullockii) are striking songbirds named for their bright orange coloration. Males have an orange head, breast and underparts, with a black throat, eye line, wings and tail. Females are yellow-orange on the underparts and olive above.
These medium-sized orioles reach lengths of 6.7-7.9 inches with pointed bills. Their wings are long and pointed for agile flight.
Bullock’s orioles breed in open woodlands throughout western North America. In Southern California they frequent treed yards, parks and forested areas. They construct a hanging basket nest woven from grasses, fibers and hair.
They mainly eat insects like beetles, grasshoppers, caterpillars, bees, and wasps. They also feed on nectar, fruits and berries. Bullock’s orioles forage among trees, sometimes catching insects in midair during flight.
The song of this oriole is a melodious whistling. Calls include sharp chits and whistled sweees. Males sing from high perches to attract mates and defend territories
Hooded Oriole
The hooded oriole (Icterus cucullatus) is a striking yellow and black species found in the southwestern United States. Male hooded orioles have a bright yellow body contrasting with black wings, tail and head. Females are yellow-green overall with darker wings.
These birds measure 6.3-7.5 inches in length with pointed bills suited for eating nectar and insects. Their wings are rounded and tail is moderately long.
Hooded orioles prefer open habitats with scattered trees like palm oases and residential areas. In Southern California they frequent parks, palms and yards. They build a hanging pouch nest made from palm fibers, grasses and feathers.
The diet of this oriole consists of nectar, insects, and some fruit. They often feed on flower nectar from palms, ocotillo, and agaves. Hooded orioles hawk flying insects and glean caterpillars from trees.
Males sing a loud, rich whistle that varies geographically. Their common call is a loud, sharp chek or quoit. These vocalizations help attract mates and defend nesting areas.
Lesser Goldfinch
The lesser goldfinch (Spinus psaltria) is a small finch with bright yellow plumage. Males have a green back, black wings, white rump, and black cap. Females are duller olive-yellow overall without the black cap.
Lesser goldfinches measure just 3.5-4.3 inches in length and weigh 0.3 ounces. Their conical bill is suited for eating seeds. Wings are short and rounded for brief flights.
This finch inhabits chaparral, orchards, and weedy fields across the west. In Southern California, lesser goldfinches frequent backyards, parks and other open habitats with seeding plants. They nest later than most birds, from July-September.
Their diet is mainly composed of seeds from composite plants like thistles and dandelions. Lesser goldfinches also eat buds, berries and some insects. They forage in flocks, feeding on the ground or in bushes and trees.
Lesser goldfinch song is a sweet series of musical warbles and whines. Their call is a high pitched whee-whee or deee-dit. Males sing from exposed perches to defend territories.
Yellow-rumped Warbler
Yellow-rumped warblers (Setophaga coronata) are common, colorful birds that migrate through Southern California each spring and fall. Adult males have blue-gray heads, a yellow crown and rump, white belly, and bold black streaks. Females lack the vibrant plumage of males.
These warblers are relatively small at just 4.7-5.5 inches long with thin pointed beaks. Their wings are rounded for flight and tail has white spots.
Yellow-rumped warblers breed in coniferous forests further north and west. During migration they stop in a variety of open to semi-open habitats like parks, yards and woodlands. They mainly eat insects like flies, beetles, caterpillars, and wasps.
Males sing a series of musical trills described as “I’m so happy, happy, happy.” Their common call is a rough check note. Yellow-rumped warblers sing during the breeding season to attract mates and defend territories.
Common Yellowthroat
The common yellowthroat (Geothlypis trichas) is a small songbird named for the bright yellow throat patch on males. Their upperparts are olive-gray with a black face mask. Females lack the mask and their colors are more muted overall.
Common yellowthroats reach 4.3-5.1 inches in length. They have a short bill suited for eating insects. Wings are rounded and tail is long in comparison.
This species inhabits thick wet vegetation across North America. In Southern California they occur in marshy areas with dense grasses and willows. Common yellowthroats often skulk low in vegetation but sometimes pop up to sing from more exposed perches.
They feed on insects like beetles, caterpillars, and spiders picked from foliage. Sometimes they will hawk flying insects. This species frequents the lower canopy and ground level while foraging.
The song of common yellowthroats is described as a rolling witchity-witchity-witchity. Calls include a loud, electric chimp and softer quint quint. Males sing to establish territories and attract females during breeding season.
Importance
These yellow-headed birds play important roles in the ecosystems of Southern California. Insect-eating species like warblers and orioles help control pest insect populations. Seed-eating finches and blackbirds can disperse native plants through their droppings. Nectar-feeders like orioles pollinate flowers of plants like agaves.
Many of these yellow-headed birds are migratory, traveling huge distances each year between breeding and wintering grounds. Conservation of their habitats along migratory flyways is important to sustain populations. Some species like the western meadowlark and yellow-headed blackbird are declining in parts of their range.
Beyond environmental benefits, these colorful birds have cultural significance. Species like the western meadowlark represent prairie states and hold a place in the arts. Backyard birding of yellow-headed species is also a popular hobby for many people.
