Plain-breasted Ground Dove
Columbina minuta
Small, inconspicuous dove of savannas and open grassland with scattered low bushes and palmettos; also found locally in cane fields and pastures. Usually found in pairs or small groups, sometimes associating with other ground doves. Both sexes are rather plain overall, with diagnostic purple marks on the back, although the color is often hard to see. The female can be easily confused with the much commoner Ruddy Ground Dove, which also has a plain breast, but the Ruddy Ground Dove is larger and warmer brown overall; also note vocal differences.
识别特征
With a total length of approximately 14–16 cm (5.5–6.5 in) and a weight of 24–26 g (0.85–0.92 oz), this species averages slightly smaller than the common ground dove. The plain-breasted ground dove may be the smallest pigeons or doves by mass, though the more heavily built but almost tailless dwarf fruit dove of Southeast Asia is typically shorter in overall length.
分类信息
In 1760 the French zoologist Mathurin Jacques Brisson included a description of the plain-breasted ground dove in his six volume Ornithologie based on a specimen that he mistakenly believed had been collected in Santo Domingo of the Dominican Republic. He used the French name La petite tourterelle brune d'Amérique and the Latin Turtur parvus fuscus americanus. Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature. When in 1766 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the twelfth edition, he added 240 species that had been previously described by Brisson. One of these was the plain-breasted ground dove which he placed with the other pigeons in the genus Columba. Linnaeus included a brief description, coined the binomial name Columba minuta and cited Brisson's work. The specific name minuta is from the Latin minutus meaning "small". The type locality was subsequently corrected to Cayenne in French Guiana. The plain-breasted ground dove is now placed in the genus Columbina that was introduced by the German naturalist Johann Baptist von Spix in 1825.<p>Four subspecies are recognised:

Red-capped Lark
Calandrella cinerea
A medium-sized, slender, pipit-like lark with a long tail and a weak bill. It always has a distinctive white eyebrow, a diagnostic brick-red crown that can be raised like a small crest, and reddish sides to the chest. Small to large groups are resident or locally nomadic, occupying cropped grasslands, open fields, edges of wetlands, and other open areas. Surprisingly cryptic on the ground, pairs or small groups run 5-10 meters and then pause, foraging for seeds and insects. The species can also be found drinking at waterholes. Calls include semi-musical chirps and short buzzy notes. The song, often given in an extended undulating pipit-like display flight, consists of semi-musical chirping notes, often in series, often incorporating imitations of other birds.
Chestnut Woodpecker
Celeus elegans
A “classic” Celeus woodpecker, medium-sized and rufous overall with a shaggy crest. Unlike the similar Scale-breasted and Waved Woodpeckers, Chestnut Woodpecker mostly or entirely lacks black markings on the body and wings. Sexes are similar, but males have a red mustache. The color of the crest varies across subspecies: some birds have a contrasting golden crest, while others have a plain rufous crest like the rest of the body. Widespread but uncommon across much of northern South America, where it inhabits the mid-levels of lowland forests and edges, especially around water.
Yellow-winged Vireo
Vireo carmioli
Small yellowish bird; note bold wingbars and face pattern with short pale eyebrow and arc under the eye. Yellow underparts sometimes bright, sometimes paler whitish, but always some yellow tones. Could be mistaken for a tyrannulet but note thicker bill and more horizontal posture. Usually seen singly or in pairs, following a mixed-species flock through forest, edge, and second growth. Found at relatively high elevations in its limited range. Song is a slow series of short phrases, like a squeaky Yellow-throated Vireo.
