House Finch
Haemorhous mexicanus
Frequents suburban settings across North America, along with open woods, brushy field edges, and deserts. Males vary in shades and intensity of red. Some males are yellow or orange. Females are drab gray-brown overall with plain faces and blurry streaks on underparts. Similar to Purple and Cassin's Finch, but House Finch males are more orangey-red with color equally bright on crown, throat, and breast. Red color is mostly restricted to head and upper chest, contrasting with cold gray-brown nape, back, and wings. Pale sides show distinct brown streaks, lacking red tones. Females lack bold face pattern and have more diffuse patterning overall. Often sings loudly in neighborhoods and visits feeders.

The house finch is a moderate-sized finch, 12.5 to 15 cm (5 to 6 in) long, with a wingspan of 20 to 25 cm (8 to 10 in). Body mass can vary from .mw-parser-output .frac{white-space:nowrap}.mw-parser-output .frac .num,.mw-parser-output .frac .den{font-size:80%;line-height:0;vertical-align:super}.mw-parser-output .frac .den{vertical-align:sub}.mw-parser-output .sr-only{border:0;clip:rect(0,0,0,0);clip-path:polygon(0px 0px,0px 0px,0px 0px);height:1px;margin:-1px;overflow:hidden;padding:0;position:absolute;width:1px}16 to 27 g (9⁄16 to 15⁄16 oz), with an average weight of 21 g (3⁄4 oz). Among standard measurements, the wing chord is 7 to 8.4 cm (2+3⁄4 to 3+1⁄4 in), the tail is 5.7 to 6.5 cm (2+1⁄4 to 2+1⁄2 in), the culmen is 0.9 to 1.1 cm (3⁄8 to 7⁄16 in) and the tarsus is 1.6 to 1.8 cm (5⁄8 to 11⁄16 in).<p>Adults have a long, square-tipped brown tail and are a brown or dull-brown color across the back with some shading into deep gray on the wing feathers. Breast and belly feathers may be streaked; the flanks usually are. In most cases, adult males' heads, necks and shoulders are reddish. This color sometimes extends to the belly and down the back, between the wings. Male coloration varies in intensity with the seasons and is derived from the berries and fruits in its diet. As a result, the colors range from pale straw-yellow through bright orange (both rare) to deep, intense red. Adult females have brown upperparts and streaked underparts.<p>The house finch's songs typically consist of a series of high-pitched musical jumbles ending with a distinct high note, wheer. Calls from flight include a soft cheet or wheat, with perched birds giving a more drawn-out version.

分布与栖息地
House finches are mainly permanent residents throughout their range, some birds migrate to the south, with adult females moving longer distances than males. Their breeding habitat is urban and suburban areas across North America, as well as various semi-open areas in the west from southern Canada to the Mexican state of Oaxaca; the population in central Chiapas may be descended from escaped cagebirds. Analyses of nest records from house finches in California spanning more than a century found that egg‐laying occurred significantly earlier in warmer springs.<p>Originally only a resident of Mexico and the southwestern United States, house finches were introduced to eastern North America in the 1940s. The birds were sold illegally in New York City as "Hollywood Finches", a marketing artifice. To avoid prosecution under the Migratory Bird Treaty Act of 1918, vendors and owners released the birds. They have since become naturalized; in largely unforested land across the eastern U.S. they have displaced the native purple finch and even the non-native house sparrow. Sometime in the 19th century, they were introduced to Hawaii and are now abundant on all its major islands.<p>According to the Partners in Flight database, there are estimated to be 40 million house finches across North America.<p>Instances of naturalization originating in escapes or releases of cage birds have been recorded in Europe, such as in 2020 in Murcia, (Spain).

Ochre-breasted Foliage-gleaner
Anabacerthia lichtensteini
Medium-sized foliage-gleaner with a short bill and attractive head pattern giving it a “cute” look. The crown and mask are gray-brown contrasting with a buffy-yellow eyebrow and throat. Buffy and unstreaked below and rufous-brown above. Found in the upper levels of forests and second growth. The song is a short fast trill.
Ruby-crowned Kinglet
Corthylio calendula
Tiny, hyperactive songbird with an uneven white eyering. Plain olive overall, with slightly brighter greenish edges on the wing and tail feathers. The namesake ruby crown is only present on males, and usually concealed. When agitated, it can be flared up into a bright expressive crest. Breeds in coniferous forests. In migration and winter, found in basically any wooded habitat, including deciduous forests, shrubby woodland, and field edges. Often forages quite low to the ground, sometimes joining mixed flocks of other songbirds. Energetic, moving quickly and flicking its wings. Listen for short, harsh call notes, usually doubled, and surprisingly loud song for such a small bird. Compare with Hutton’s Vireo, which is similar in plumage but has a thicker bill and forages more sluggishly.
African Crake
Crecopsis egregia
Chunky, mid-sized rail. Note the black-and-brown scalloped back, gray head and chest, barred belly, reddish bill and yellowish legs. Found in mostly seasonal wetlands, such as flooded grassland. Most often seen trailing its long legs when it flushes from grass before quickly settling back down. Two common vocalizations are a series of dry “krrr” notes and a series of deeper “du-da” notes. Similar color pattern to African Rail, but African Crake has a shorter bill and a spotted back.
