Great Barbet
Psilopogon virens
This largest of the barbets is colorful, but often appears all-dark from a distance. No other barbet in its range combines the features of a massive pale bill, black head, and dark olive back. Sluggish and shy; tends to stick to dense forest canopy, where it is difficult to see. Its loud hooting song (typically a series of two repetitive notes) is often the only indication of this species’s presence. Also gives a harsh, screaming “karrrrr” that has a gull-like quality.
Identification
The great barbet has a blue head, large yellow bill, brown and green-streaked body, belly and a red vent. The plumage is green. It is the largest barbet species with a body length of 32–35 cm (13–14 in) and a weight of 192–295 g (6.8–10.4 oz).
Taxonomy
Bucco virens was the scientific name proposed by Pieter Boddaert in 1783 for a great barbet that had been described by Georges-Louis Leclerc, Comte de Buffon in 1781 based on a specimen collected in China. It was illustrated in a hand-coloured plate engraved by François-Nicolas Martinet.<p>It was placed in the genus Megalaima proposed by George Robert Gray in 1842 who suggested to use this name instead of Bucco. In the 19th and 20th centuries, the following great barbet zoological specimens were described:<p>Molecular phylogenetic research of barbets revealed that the birds in the genus Megalaima form a clade, which also includes the fire-tufted barbet, the only species placed in the genus Psilopogon at the time. Barbets formerly placed in this genus were therefore reclassified under the oldest genus name of Psilopogon.<p>Four great barbet subspecies are recognised as of 2014:<p>Results of a phylogenetic study of Asian barbets indicate that the great barbet is most closely related to the red-vented barbet (P. lagrandieri) occurring in Cambodia, Laos and Vietnam.

Range and habitat
The great barbet is a resident breeder in the lower-to-middle altitudes of the Himalayas, ranging across northern Pakistan, India, Nepal and Bhutan, Bangladesh and some parts of Southeast Asia, as far away as Laos.
- Migration
- Vertical migration
Behavior
The great barbet's nesting season is from April to July. It typically builds nests in tree holes. Both male and females take care of the young. Its diet consists mainly of fruits and insects.The male's territorial call is a very loud kay-oh. The alarm is a harsh keeab, and another call is a repetitive piou-piou-piou-piou.

Amazonian Motmot
Momotus momota
Medium-sized motmot. Green with orange underparts, black mask, and blue crown. Other motmots in its range have orange heads. Found in the under and midstory of a variety of forest habitats, including humid forest, semi-humid forest, and forest edge. It often sits quietly on exposed perches, wagging its tail from side to side. Listen for its song, a low “BOO-boop” with the emphasis on the first syllable; often heard around dawn and dusk.
Streaky-breasted Spiderhunter
Arachnothera affinis
Generic-looking spiderhunter, olive-green above with a streaky gray breast. The only spiderhunter on Java with well-defined streaking on dull gray underparts; the only other streaked spiderhunter is Long-billed, which has a much more impressive bill, as well as poorly-defined streaks and a yellow-washed belly. Immatures with unstreaked underparts may be confusing if seen, but general shape and patterning, as well as the presence of an adult, should be helpful. A species of foothill forests, where it forages in forest and forest edge habitats. Gives harsh, noisy chattering calls.
Indigo-capped Hummingbird
Saucerottia cyanifrons
Medium-sized hummingbird with restricted range in central Colombia. Distinctive: all green with a contrasting blue crown, white leg puffs, and reddish lower mandible. Occurs in the middle to upper levels of forests, edges, and shrubby gardens from around 1,000 to 2,000 m. Visits feeders.
