A handsome species, greenish above, with a coppery tinge and shading into reddish brown on the tail; under parts buffy, throat metallic green, and a broad white streak behind the eye. They breed on the ranges making a similar nest to those of other Hummers, placed on weeds or bushes near the ground. The eggs cannot be distinguished from those of the majority of other species. 440.1. WHITE-EARED HUMMINGBIRD. _Basilinna leucotis._ Range.--A Central American and Mexican species, casually found on the ranges in Southern Arizona. The plumage of this species is greenish above and below, being metallic green on the breast; the forehead, sides of head, and throat are iridescent blue and a white line extends back from the eye. 441. BROAD-BILLED HUMMINGBIRD. _Cynanthus latirostris._ Range.--Mountains of central Mexico north to southern Arizona and New Mexico. The throat of this species is a rich metallic blue; otherwise the plumage is greenish above and below, being brighter and more irisdescent on the breast. They are not uncommon on the ranges of southern Arizona, where they have been found nesting in July and August, their nest not being unlike those of the Rufous Hummer, but with the exterior largely composed of shreds of grayish bark and lichens. Their eggs are like many others of the Hummers. [Illustration 281: 439--440.1--441.] [Illustration: deco.] [Illustration: right hand margin.] Page 280 PERCHING BIRDS. Order XVII. PASSERES COTINGAS. Family COTINGIDAE 441.1. XANTUS BECARD. _Platypsaris aglaiæ albiventris._ Range.--Mexico; north casually to the southern border of Arizona. This peculiar species is grayish above and lighter gray below, has dark slaty crown, and a patch of rose color on the lower throat. This is the only representative of this tropical family that has been found as yet over the Mexican border, but its near ally, the Rose-throated Becard has been found within a very few miles and will doubtless be added to our fauna as an accidental visitor ere long. Their nests are large masses of grasses, weeds, strips of bark, etc., partially suspended from the forks of branches. Their eggs number four or five and are a pale buffy gray color, dotted and scratched with a pale reddish brown and dark gray. Size .95 × .70. The one figured is from a set in the collection of Mr. Crandall, taken June 1, 1897 at Presidio Sinaloa, Mexico. FLYCATCHERS. Family TYRANNIDÆ Flycatchers, which are found only in America and chiefly in the tropics, are insect-eating birds, generally having a grayish colored plumage, sometimes adorned with a slight crest or a coronal mark of orange, red, or yellow. Only two of the species found in North America are gaudy in plumage, the Vermilion, and the Derby Flycatchers. They all have the habit of sitting erect on a dead twig, and watching for passing insects, which they catch on the wing. 442. FORK-TAILED FLYCATCHER. _Muscivora tryannus._
