Orchard Oriole sounds: They make a jumbled series of whistles that lasts about 3 to 4 seconds.

Nests of Orchard Orioles are a cup made from long grasses suspended from small branches of trees. They lay 4 – 6 eggs, which take about two weeks to hatch.

Attract Orchard Orioles to your yard with hummingbird feeders or platform feeders with cut oranges or mango. Also, plant native berry plants such as mulberries or chokeberries.

Fun fact: Orchard Orioles are the smallest species of blackbird in North America

22. Magnolia Warbler

Magnolia Warblers are not often seen in California, but some have been spotted during the fall migration in October.

Magnolia Warblers males are black on the back and yellow underneath. They have black streaking forming a ‘necklace’ on their necks and down over their bellies. Females are grayer on the back and lack the distinctive streaking down the belly.

Magnolia Warblers breed across Canada and northeastern US states. They can be seen during migration in the eastern US. They spend the winter in Central America and the Caribbean.

You can find Magnolia Warblers on low branches in forests or parks, so it’s easier to spot them during migration. Their diet is insects and spiders.

Magnolia Warbler song:

Nests of Magnolia Warblers are a loose construction of grass and weeds built close to the trunk of conifer trees. They lay around four eggs that take about twelve days to hatch and a further nine days for the young to leave the nest.

Attract Magnolia Warblers to your backyard with native shrubs and trees for them to rest in during migration.

Fun Fact: Magnolia Warblers show off the white spots on their tails to attract females and to warn off rivals.

23. Baltimore Oriole Female

Baltimore Orioles are not often seen in California, but they have been occasionally spotted here all year.

Baltimore Orioles are a colorful sign of spring in the east of North America. The adult males are bright orange and black with white wing bars on the black wings.

Baltimore Orioles then migrate to Florida, Central America, and the Caribbean for winter, leaving as early as July.

Baltimore Orioles can be found high up in open woodland, riverbanks, and forest edges foraging for insects and fruit, and they often come to parks and backyards.

Their diet is insects such as beetles, crickets, grasshoppers, spiders, and snails. They also help eat pest species and eat a wide variety of fruits, but they can damage crops such as raspberries, mulberries, cherries, bananas, and oranges.

Baltimore Oriole sounds: The flute-like sound of Baltimore Orioles is one of the joys of spring. They also make chattering and sharp alarm calls.

Attract Baltimore Orioles to your backyard with oranges cut in half on a platform feeder or hanging them from trees. Also, try oriole feeders filled with sugar water. Planting some fruiting plants and nectar plants such as raspberries, crab apples, and trumpet vines should also attract them.

Fun fact: Baltimore Orioles make incredible hanging bag-like nests woven from fibers.

24. Hooded Warbler

Hooded Warblers have occasionally been spotted in California all year.

Male Hooded Warblers have a bright yellow face with a distinctive black hood and throat. They are yellow underneath and olive-green above. They are white under their tail, which is visible when they flick their tails up.

• Weight: 0.3-0.4 oz (7-11 g)
• Wingspan: 6.7-7.9 in (17-20 cm)

Black-throated Green Warblers can mostly be seen during their long migration over the eastern US up to their breeding grounds in northeastern US states and Canada. Their winter grounds are in Mexico, northern South America, and the Caribbean.

You can find Black-throated Green Warblers high up in forests eating insects, and their black throat is an easier way to tell them apart from other small yellow birds.

Black-throated Green Warblers song:

Nests of Black-throated Green Warblers are in small trees and close to the truck. The nest is made from twigs and bark woven together with spiders’ webs and lined with animal hair, moss, and feathers. They lay around four eggs, which take twelve days to hatch and an additional ten days for the young to leave the nest.

Attract Black-throated Green Warblers to your backyard with mature trees.

Fun Fact: Male Black-throated Green Warblers can sing over 400 times in an hour and perform a ‘gloating’ flight when they have chased off rivals.

27. Prothonotary Warbler

Prothonotary Warblers are not common in California, but there have been some recorded sightings during migration.

Prothonotary Warblers song:

Nests of Prothonotary Warblers use abandoned woodpecker nest holes in trees that are near water. Males place moss in the hole, and then the female makes a cup-shaped nest from grass and leaves, and other plant material.

They lay up to seven eggs which take about two weeks to hatch and an additional ten days for the young to leave the nest.

Attract Prothonotary Warblers to your backyard with a nest box if you live near wet areas.

Fun Fact: Prothonotaries are the bright yellow robes worn by members of the Roman Catholic church, and that is how the Prothonotary Warblers got their name.

28. Dickcissel

Dickcissels have occasionally been spotted in the south of California during migration.

The male Dickcissel is a striking, chunky bird with its identifiable black throat patch and yellow chest. The yellow eyebrow line is stark against their grayish head. The female also has the same markings but with a slightly paler or duller tone. However, she does not have a black throat patch, and there is only a faint hint of the yellow chest.

You can find Dickcissel in meadows and prairies, tall grasslands, light-grazed pastures, and roadsides. 

Dickcissel feed on insects and seeds. In the summer, they feed on grasshoppers, caterpillars, beetles, and crickets. At other times of the year, they may feed on seeds, weeds, grasses, and cultivated grain. 

Dickcissel Song:

Nests of Dickcissel can be found in thick but small shrubs, grasses, and trees, up to four feet high. The bulky nests are made out of weeds, grass, and leaves and made soft by fine grass and animal hair. The female may lay up to six eggs that hatch in two weeks. The young are ready to fly after around ten days. 

Fun fact: When it’s time to migrate during the fall, the Dickcissels come together, and their numbers can reach from thousands to millions when they reach their winter grounds.

29. Painted Bunting – Female

Painted Buntings have been occasionally spotted in southern California during winter.

Painted Bunting males are a brightly colored patchwork of color with mostly red coloring underneath and with bright blue heads, green wings, and backs. Females are bright yellow-green.
