英文简介

这是一个叫贝尔的生物学家发现，所以称贝氏黄喉地莺。

TheBelding's Yellowthroat(Geothlypis beldingi) is a New World warbler. It is a resident breeder endemic to southern Baja California, Mexico.

It is closely related to Common Yellowthroat, Altamira Yellowthroat and Bahama Yellowthroat, with which it forms a superspecies, and was formerly considered conspecific.

The breeding habitat is freshwater marshes and lagoons, usually with cattails. It builds a cup nest of dead cattails which is usually attached to low on the stem of a living cattail. It lays 2-4 eggs, usually 3. Like other yellowthroats it forages low in vegetation and feeds oninsectsand other small invertebrates.

The Belding's Yellowthroat is 14 cm long with an olive-green back and bright yellow belly. The adult male of the southern nominate raceG. b. beldingihas yellow underparts, a black facemask and yellow forecrown. The female is similar, but lacks the black mask and has an olive crown. It is similar to Altamira Yellowthroat, but separated from it by the width of Mexico. This race has been drastically affected by habitat loss, and is now restricted to several small marshes in southernmost Baja California [the estero at San Jose del Cabo and the lagoon at Todo Santos; August, 2007].

The male of the northern subspeciesG. b.goldmaiihas a pale belly and grey forecrown, making it very similar to some non-migratory southwestern races of Common Yellowthroat, which, however, do not overlap in range. It is larger and slightly brighter than the migratory races of Common Yellowthroat which winter in Baja California, and the male's mask extends further onto the nape than is the case with the visitors. This race is still fairly common, but its range is shrinking through habitat loss.

The song of Belding's Yellowthroat is a loudwichety wichety wichety wich, similar to that of Common Yellowthroat but deeper, fuller, and with some buzzes. The call is a softjip, again similar to Common Yellowthoat.

This species is named for Lyman Belding, a prominent Californian naturalist
