591, ♀ ad., Camp Lowell, June 25. Length, 9.40; extent, 13.60; wing, 4.15; tail, 4.10; culmen, 1.12.
102. Myiarchus cinerescens Lawr. Ash-throated Flycatcher.—Specimens were obtained at Tombstone, Tucson, and Camp Lowell. In the latter locality the bird was common through June and was presumably breeding, although no nests were actually found. At all the points in Arizona where they were observed these Flycatchers frequented the timber in valleys and along streams, none being seen among the denser forests of the mountains.
103. Myiarchus lawrencii (Giraud) Baird. Lawrence’s Flycatcher.—This pretty Myiarchus, scarcely larger than our common Phoebe, was met with only among the Santa Rita Mountains, where it was apparently not uncommon, although its distribution seemed to be very local, most of Mr. Stephens’ specimens being taken in a single cañon. They haunted the banks of streams, perching on dead limbs and taking frequent flights after insects. The only note heard was a short, mournful “peeúr.” No nests were found, but a female shot May 17 was laying.
In my preliminary announcement[[96]] of the occurrence of this species in Arizona I inadvertently gave the number of specimens as eight, whereas nine were really obtained. These show little variation in color or markings, but the females are slightly smaller than the males. The characters which separate M. lawrencii from its respective allies, M. tristis of Jamaica and M. nigricapillus of Central America, are well maintained in this series.
