Canyon Towhee

Melozone fusca

Large, stocky, long-tailed sparrow. Uniform matte brown body, with buffy throat and orange undertail coverts. Also note reddish-brown crown and messy dark streaks on upper breast (usually with a dark central spot). Occurs in deserts and dry grasslands with scattered dense shrubs. Forages primarily for seeds by running and hopping on the ground. Visits feeders. Essentially no range overlap with the very similar California Towhee; also note Canyon has reddish crown and lacks rusty tones on face.

It is 19 to 25 cm (7.5 to 9.8 in) long, and has a noticeably long tail, at 8.2 to 11 cm (3.2 to 4.3 in).

Among standard measurements, the wing chord is 8.2 to 10.1 cm (3.2 to 4.0 in), the bill is 1.4 to 1.7 cm (0.55 to 0.67 in) and the tarsus is 2.3 to 2.7 cm (0.91 to 1.06 in). It is earthy brown in color, with somewhat lighter underparts and a somewhat darker head with a rufous cap (except that birds in central Mexico have the cap the same color as the back); there is also a slightly reddish area beneath the tail. There is little sexual dimorphism.

分类信息

The taxonomy of the group of towhees to which this species belongs is debated. At the higher level, some authors place the towhees in the family Fringillidae. Within the genus, there has been dispute about whether the canyon towhee is a distinct species from the California towhee (Melozone crissalis) found in coastal regions from Oregon and California in the United States through Baja California in Mexico. At present, molecular genetics seems to have settled this issue in favour of separation of the species.

Yellow Rail

Yellow Rail

Coturnicops noveboracensis

Exceptionally secretive little rail. Overall the color of a perfectly toasted marshmallow; back pattern more complex with streaks of gold and black crossed by intricate white bars. Almost never seen in the open. When flushed, look for bold white patch on the inner flight feathers. Most similar to juvenile Sora; separable by back pattern and habits. If you're looking at a rail in the open, it's almost certainly not a Yellow Rail. Found in moderately wet marshes and meadows, where it finds cover among dense grasses. Most easily detected at night when it sings a distinctive song that sounds like two stones being tapped together: "tick-tick, tick-tick-tick", almost always in alternating sets of two and three notes, often confused with cricket frogs.

Black-and-rufous Warbling Finch

Black-and-rufous Warbling Finch

Poospiza nigrorufa

Medium-sized finch. Gray above with cinnamon underparts, a white center to the belly, and a white-tipped tail. Note the long white eyebrow that becomes cinnamon behind the eye and the white moustache stripe.  Favors shrubby areas and open woodland near water, but also frequents gardens. Sings a series of three notes: “tweet tweet-chew,” or “Who dressed you?”

Rufous-chested Flycatcher

Rufous-chested Flycatcher

Ficedula dumetoria

This handsome little flycatcher has the endearing habit of fanning its tail and flicking its wings when agitated. The male’s long slender white eyebrows and orange breast make him unmistakable; wintering male Mugimaki Flycatchers may cause some confusion, but that species has a smaller, block-like eyebrow patch and a broader, shorter white wing patch. Females are brown above and whitish below with an orange chest and rufous tail; her combination of plain brown wings, warm-toned tail, and a fairly uniform head pattern separate her from female Snowy-browed and Mugimaki Flycatchers. Female “blue flycatchers” can be similar, but they are more slender and have proportionally longer bills. Found in foothill and montane forests, where it forages in dense low thickets, typically singly or in pairs. Song is a brief 3–4-note phrase of very high, thin notes: “tsee-a-tsee-tsee”, or “tsee-ah-tsee”.
