Violet Sabrewing
Campylopterus hemileucurus
Very large, spectacular, and aggressive hummingbird of humid evergreen forest in highlands and foothills, descending locally and seasonally to lowlands in southeastern Mexico. Feeds at all levels at flowers and at times in canopy of roadside trees. Note the very large size, thick arched bill, and big, flashy white tail corners. Male’s amazing purple plumage often looks blackish overall, but when it catches the light—wow!
Identification
The violet sabrewing is the largest hummingbird of Mexico and Central America. It is 13 to 15 cm (5.1 to 5.9 in) long and weighs 9 to 12 g (0.32 to 0.42 oz). Both sexes have a black bill, though those of subspecies C. h. mellitus are longer than the nominate's. Males of the nominate subspecies have a dusky crown with a bluish green gloss. Their nape and upper back, face, and underparts are metallic violet blue that is somewhat bluer on the belly. Their lower back and uppertail coverts are metallic green. Their central tail feathers are bluish green to bluish black and the rest blackish with wide white tips. Females have a dusky crown and metallic green to bronze green upperparts with a more bluish green rump. They have a violet blue throat. Their underparts are mostly gray with a whiter belly and metallic green spots along the sides and green undertail coverts. Their central tail feathers are bluish green and the rest blacker with wide white tips.<p>Males of subspecies C. h. mellitus have more green on their upper parts than the nominate and almost entirely violet underparts with no blue on the belly. Female's upper-parts have a coppery tinge and their throat is violet.

Range and habitat
The nominate subspecies of violet sabrewing is found from the Mexican states of Guerrero and Veracruz intermittently south through Guatemala, southern Belize, Honduras, and El Salvador into northern Nicaragua. Subspecies C. h. mellitus is found most of the length of Costa Rica into western Panama. The species inhabits the edges and interior of humid evergreen montane forest and mature secondary forest, banana plantations, and gardens. In Mexico, it generally ranges in elevation between 500 and 2,000 m (1,600 and 6,600 ft) but occurs as high as 2,500 m (8,200 ft). In Costa Rica, it ranges between 1,500 and 2,400 m (4,900 and 7,900 ft).

Behavior
The violet sabrewing is mostly sedentary, but individuals frequently move to lower elevations after the breeding season.<p>The violet sabrewing feeds on nectar primarily by trap-lining, visiting a circuit of flowering plants. Males occasionally defend patches of flowers and are dominant over other hummingbirds. The species forages mostly in the understory, often on Heliconia, banana (Musa), Cephalism, and Palic urea though it visits others as well. It frequents nectar (sugar water) feeders and chases other hummingbirds from them. In addition to nectar, violet sabrewings also eat arthropods gleaned from foliage and spiderwebs.<p>The violet sabrewing breeds during the local rainy season, which ranges from June to September in Mexico and May to November in Costa Rica. In the latter country they may raise two broods. Males court females by singing in leks, typically in the understory or at the forest edge. The nest is a cup of moss cemented with spiderwebs and lined with fine fibers. In Costa Rica it is often built above a ravine or stream, on a horizontal branch 1 to 6 m (3 to 20 ft) above the ground. The female incubates the clutch of two eggs for 19 to 22 days and fledging occurs 22 to 24 days after hatch.<p>The violet sabrewing's song has been described as "cheep tsew cheep tik-tik tsew cheep ..., high-pitched, piercing and ventriloquial" and as "varied, loud, sharp chipping and warbles, often punctuated with fairly shrill, slightly explosive notes". Its calls are "high, sharp chippering", "prolonged, hard chipping", and "single sharp chips given in flight."

Pernambuco Foliage-gleaner
Automolus lammi
Cinnamon above and paler below; note the striking white throat and pale eyes. Found in the understory of a precious few patches of humid forest and old second growth, where it usually accompanies mixed-species flocks. The song is a vigorous fast series of 4–6 harsh nasal “ki-dee” notes. The similar-looking but geographically distant White-eyed Foliage-gleaner’s song is very different (a fast series of 5–7 slurred notes).
Black-and-white Triller
Lalage melanoleuca
A medium-sized bird of lowland and foothill forest canopy. Has a black tail with white corners, black wings with a large white patch, and a white rump. Male has a black crown and back and entirely white underparts. Females have a gray crown and back. Northern females have white underparts with a barred throat and chest, while southern females have a gray throat and chest with faint barring below. Similar to Pied Triller, but lacks the white brow and is found in forest rather than open habitats. Song consists of a 1- to 3-syllabled whistled phrase repeated 5-20 times in a row.
Short-toed Treecreeper
Certhia brachydactyla
Difficult to separate from Eurasian Treecreeper: note slightly longer bill, shorter hind claw, browner flanks, and even steps on the wingbar. In the field best separated by voice, a penetrating "tut." Where it overlaps in range with Eurasian Treecreeper tends to be found in more deciduous woodlands at lower altitudes and in farmlands and parks.
