While recreationally harvesting green crab has been allowed for decades, the Oregon Fish and Wildlife Commission recently increased the daily bag limit to 35 crab. This gives recreational shellfishers an opportunity to help native shellfish by taking more of these invaders home. European green crab are an invasive species in Oregon. While recreational harvest is allowed (35 per day), harvesters must correctly identify these crabs (see below) as they often are mistaken for native species. Commercially harvesting green crab is prohibited. Green crab: Compete with native crabs for food. Larger green crab may eat smaller native shellfish. May disturb eelgrass

A large and colorful member of the sparrow family, the Green-tailed towhee is perhaps more recognizable by its eye-catching chestnut crown than by its less intense green-gray back and olive tail. As a ground forager, it spends most of its time on the ground or in thick cover, scratching about industriously in the leaf litter, and it may go unnoticed. But its catlike mewing call, which it often gives from a brushy perch, is one of the quintessential sounds of the shrublands of the east slope of the Cascades and the Great Basin. It is locally fairly common east of

This well-known ground-dwelling bird is black above on the male and brown on the female, including the entire head and upper breast. On both sexes the upperparts are spotted with white on the wings and the long tail. It has rufous sides and a white belly. It frequents brushy areas and is common at bird feeders wherever seed is scattered on the ground, but does not feed far from cover. The varied song usually has one to three parts. The Spotted towhee breeds statewide and winters primarily west of the Cascades and in small numbers in lowland areas east of

The California towhee can be found in chaparral habitats of southern Oregon, quietly flitting in and out of the brush in search of seeds. It is a plain brown bird with a rusty throat patch and undertail coverts. It is noticeably larger than the Spotted towhee. Its long slender tail is also a useful identifying feature. Sexes cannot be told apart in the field, but juveniles can be distinguished by the extensive streaking and spotting of the underparts. The California towhee is a fairly common permanent resident throughout the Rogue, Applegate, and Illinois Valleys. Hear the song of the California

This winter visitor is a study in gray and tan, with a small dark spot on an otherwise gray breast, dull rufous stripes on the side of the head and crown, and brown wings with distinct white stripes. Tree sparrows visit Oregon only in winter, mainly in lowlands within the Blue Mountains and Owyhee upland regions with a few farther west in some years. They frequent willow clumps in grassy areas and occur occasionally at feeders. Hear the song of the American tree sparrow Photo by Eric Began, Flickr

The Chipping sparrow is a small and slender sparrow that has a distinctive sharp chip note and simple, trilling song. Breeding adults display a chestnut crown, a black eye-stripe, and crisp white eyebrow. After nesting season, both male and female lose their distinctive bright cap for a streaky dull brown head pattern that is similar to other winter sparrows. It is a common summer resident in open forests and drier woodland edges throughout Oregon and is especially abundant in the Blue Mountains. The Chipping sparrow is an Oregon Conservation Strategy Species in the Willamette Valley ecoregion. Hear the song of

This is a sparrow of the dry brushlands. The Clay-colored sparrow breeds chiefly across the northern prairies from northeast British Columbia east to Michigan and south into Colorado. It winters in the southern United States and Mexico. It has expanded its range westward and northward in recent years and is now nesting in small numbers in eastern Washington. It was seldom reported west of the Rocky Mountains prior to 1960. Since that time, it has become a regular migrant and wintering bird along the west coast.

One of the most nondescript birds found in Oregon, this sparrow makes up for its drab appearance by its extraordinary song. It is by far the most abundant bird breeding in the vast sagebrush expanses of the Intermountain West. The Brewer's sparrow is an abundant migrant and summer resident east of the Cascades summit, particularly in the southeast quarter of the state among the vast sagebrush communities of the Great Basin Shrub-steppe. In the Columbia Plateau ecoregion, it is an Oregon Conservation Strategy Species. Hear the song of the Brewer's sparrow Photo by Dave Menke, USFWS

The song of this bird is one of the characteristic sounds of spring evenings in much of the high desert country of eastern Oregon. This temperate migrant is a ground-nesting, ground-foraging bird of most of the grassland, agricultural land, and shrubs steppe habitats of Oregon. The streaked brownish plumage of the Vesper sparrow is similar to that of several small to medium-sized sparrows, except for white outer tail feathers, shown most conspicuously in flight. The Oregon vesper sparrow is an Oregon Conservation Strategy Species in the Klamath Mountains and Willamette Valley ecoregions. Hear the song of the Vesper sparrow Photo

The adult Lark sparrow is one of the most easily recognized passerines. The head pattern is sharp and crisp, with a chestnut crown and cheek patch surrounded by alternating white and black stripes. White underparts with a a small black central spot and a long, blackish tail with conspicuous white wing corners further aid identification. Courtship behaviors, including turkey-like strutting by males, differ markedly from that of other passerines. In Oregon, the Lark sparrow is a locally common summer resident and migrant east of the Cascades. Hear the song of the Lark sparrow Photo by Beken Bulgic Schneider, Flickr

This uncommon inhabitant of Oregon's high desert can be a challenge to find unless the observer becomes familiar with its territorial song and preferred habitat. Habitat requirements are specialized and population distribution and densities are highly variable from year to year in Oregon. The Black-throated sparrow occurs along boulder-strewn, sparsely vegetated slopes of arid deserts. They prefer warm dry sunny slopes of desert basins.

Although common within its range, this handsome sparrow can easily be overlooked. The gray head, black malar stripe, white eyebrow, and prominent black spot set in the middle of a white breast identify the bird. It is widespread throughout the extensive shrub-steppe of central and eastern Oregon. The principal breeding range of Sagebursh sparrow is southeast and central Oregon. It is found throughout the arid expanses of the Great Basin and usually associated with big sage. Although considered by some authors to be a sagebrush obligate, Sagebrush sparrows have been found in other plant communities exclusive of sagebrush. Hear the
