A

In the trees and vegetation along the shore look for:

A

Pigeons / Doves

..... Mourning Dove

common to abundant resident throughout campus. Highly flexible in its use of nesting substrates; nests in a variety of trees and shrubs but also uses planters, artificial ledges, the eaves of buildings, and even old nests of other species.

A

Woodpeckers

..... Acorn Woodpecker

common resident virtually wherever there are mature oaks. Social groups establish territories in which they collect acorns and cache them in the limbs and trunks of oaks, palms, eucalyptus, and occasionally the eaves of buildings. These caches are defended against Western Scrub-Jays and other groups of Acorn Woodpeckers. Although populations have declined in surrounding urban areas, those on campus should persist if mature oaks remain available.

A

occasional visitor to the Dish and Lagunita, especially from fall through spring. Forages on arthropods and small vertebrates in open areas. Ostensibly suitable breeding habitat present, but not known to nest on campus currently.

A

Jays / Crows / Ravens

..... Western Scrub-Jay

common to abundant resident throughout campus, especially in oak-dominated habitats, where it feeds on acorns. Also eats a variety of fruits (including those of the eucalyptus), preys upon insects and small vertebrates, and scavenges discarded food items at Tresidder Union. Scrub-jays on campus have been seen killing and eating fully-grown juvenile European Starlings.

A

Thrushes

..... American Robin

common resident throughout campus, nesting in a variety of trees and tall shrubs and on artificial substrates, such as planters and the eaves of buildings. Occasionally seen in flocks from fall through spring.

A

Starlings

..... European Starling

abundant resident which first bred at Stanford in 1963; found in a variety of habitat types throughout campus. Nests in a variety of artificial cavities and crevices but also uses natural cavities, including woodpecker holes. Stanford-area studies of interactions between starlings and Acorn Woodpeckers suggest that appropriation of woodpecker cavities by starlings may not have a significant impact on Acorn Woodpecker populations.

A

Wood-Warblers

..... Common
..... Yellowthroat

uncommon to fairly rare migrant in brushy habitats and tall weedy vegetation, especially near water. Occurs most regularly near Lagunita and, during migration, in scrub near the Dish.

uncommon migrant and winter resident in weedy habitats, tall grassland, and brushy vegetation in relatively open areas. Most common in weedy areas near water, as at the edge of Lagunita.

A

..... Song Sparrow

uncommon resident in weedy or brushy vegetation near water, as at Lagunita and in the wetland area south of Campus Drive between Lomita Drive and Palm Drive. Small numbers nest in these areas. During the nonbreeding season, some (possibly migrants) are occasionally found in brush, scrub, and dense weedy vegetation away from water.

..... White-crowned
..... Sparrow

common migrant and winter resident virtually throughout campus, occurring in a variety of habitat types but usually found in close proximity to the cover of brush or dense weedy vegetation.

Forages primarily on or near the ground, although in spring flocks forage in the crowns of flowering oaks and eucalyptus.

..... Red-winged
..... Blackbird

common breeder in mustard and other herbaceous vegetation on the hills near the Dish and near Lagunita, fairly rare as a breeder elsewhere on campus.

A

..... Western Meadowlark

common resident in grassland and weedy habitats near the Dish, with a few pairs possibly nesting around Lagunita and fields on the western side of campus.

A

..... Brewer's Blackbird

common to abundant resident in a variety of habitats virtually throughout campus.

A

..... Brown-headed
..... Cowbird

fairly common breeder in a variety of habitats virtually throughout campus, less common during the nonbreeding season.

A

Finches

..... House Finch

abundant resident in various habitats throughout campus. Frequently nests on artificial substrates, such as planters and the eaves of buildings.

A

..... Lesser Goldfinch

common resident in various habitats virtually throughout campus. May forage in flocks during the nonbreeding season.

A

Old World Sparrows

..... House Sparrow

common resident around artificial structures throughout campus. This species nests in artificial crevices and cavities in buildings and other structures, and occasionally in bluebird nest boxes. Although it often forages on seeds in weedy and brushy habitats, the House Sparrow most frequently feeds on human leftovers.
