Balsas Screech-Owl
Megascops seductus
Medium-sized owl (but large for a screech-owl) with short ear tufts and brownish (not yellow) eyes. Fairly common in scrubby woodland, thorn forest, and edge of interior southwest Mexico where it is endemic. Sometimes seen hunting beside quiet roads. Usually detected by its gruff, bouncing ball song. Mottled Owl occurs in same areas but is slightly larger, with a rounded head and thicker dark streaks below.
Identification
The Balsas screech owl is among the larger members of genus Megascops; it is 24 to 27 cm (9.4 to 10.6 in) long and weighs between 150 and 174 g (5.3 and 6.1 oz). Its facial disc is grayish brown with brownish markings and a darker border. Its "ear" tufts are short. The crown and upperparts are also grayish brown; the crown has darker streaks and the upperparts have a pinkish blush and dark streaks and other marks. The closed wing shows two bands of whitish spots. The underparts are paler than the upperparts and have narrow dark streaks and faint vermiculation.

The Balsas screech owl is monotypic.

Range and habitat
The Balsas screech owl is endemic to interior southwestern Mexico. Its range is centered on the valley of the Balsas River from southern Jalisco southeast into central Guerrero. It inhabits arid open and semi-open areas such as deciduous woodland with cactus, thorn forest, and secondary forest. It can also be found in tropical scrublands and the edges of cultivated areas. In elevation it ranges from 600 to 1,500 m (2,000 to 4,900 ft).

Behavior
Like most other screech owls, the Basas screech owl is nocturnal. Its hunting methods have not been described, but its diet apparently includes insects, other arthropods, and small vertebrates.<p>Very little is known about the Balsas screech owl's breeding phenology. It is assumed to nest in cavities in trees and cacti like others of its genus.<p>Both sexes of the Balsas screech owl perform a territorial song described as "a rather loud series of gruff notes accelerating to a trill ('bouncing-ball' rhythm), book-book-bokbokbobobobrrrrr". A possible courtship song is "a series of gruff, screaming 'whinny' trills".

Chiriqui Quail-Dove
Zentrygon chiriquensis
Plump ground-dwelling dove, quite bright rufous overall compared with other quail-doves. Entire body is warm rufous, similar to Ruddy Quail-Dove, but note gray crown and black mustache line. Pinkish-red legs. Sexes alike. Prefers forests, usually on the ground unless flushed up into the lower levels of a tree. Like most quail-doves, often best seen by quietly walking along trails at dawn and dusk.

Pale-tipped Tyrannulet
Inezia caudata
Small, inconspicuous flycatcher found in the understory of coastal and gallery forests as well as mangroves. Key field marks are longish tail, whitish lores, stout bill, and (at close range) pale eyes. Forages low and occasionally forages on the ground; tumbles through vegetation in pursuit of insects. Quite vocal; calls include a slow series of descending whistles, loud for the bird’s size, and stuttering contact calls, both of which are distinctive once learned.

Narrow-billed Tody
Todus angustirostris
A small, gemlike species that prefers higher elevation moist woodlands, but also occurs in coffee plantations. The rather large head, long bill, and short tail create a profile shared only by the Broad-billed Tody within its range. Both species have bright green upperparts and a red throat and sides. Note especially the pale eyes of Narrow-billed Tody, as compared to the dark eyes of Broad-billed. Many Broad-billed also have a buff-yellow wash below, which the Narrow-billed lacks. On birds lacking buff below, the Broad-billed can be identified by its all red lower bill, which is black tipped in the Narrow-billed. Further clues to identification include altitude, with this species occurring above 700 meters elevation and the Broad-billed occurring mostly below 700 meters. The Broad-billed also tends to forage higher within woodlands on more open perches. Vocalizations include a buzzy “chik-zhwik” with second note slightly upslurred and a rapid buzzy chatter at about 14 notes per second; compare this with the quick “weep” or “whip” uttered by the Broad-billed.
