Finches are seed-eating passerine birds, that are small to moderately large and have a strong beak, usually conical and in some species very large. All have twelve tail feathers and nine primaries. These birds have a bouncing flight with alternating bouts of flapping and gliding on closed wings, and most sing well.
The warbling white-eye is olive green on its back, from anterior to posterior, and is pale green on its underside. Its feet, legs, and bill range from black to brown. [6] It has a green forehead and a yellow throat. The white-eye has rounded wings and a long, slender bill – both of which indicate this bird to be very acrobatic.
These facts document strong community-wide exploitative competition for food between the Japanese white-eye and passerine birds native to Hawaii, meaning the white-eye depletes the availability of food for other bird species. They also compete for space; the white-eye has expanded its range into remote areas within the two decades 1980–2000.

Species are assessed solely according to their population in the Philippines and hence may not be in line with other conversation lists such as the IUCN Red List which list the Crab-eating macaque (including subspecies the Philippine long-tailed macaque) as vulnerable but is not included in the 2019 release of the Philippines' national Red List ...
This streaked spiderhunter has pierced the side of a closed hibiscus flower and is drinking the nectar without pollinating the flower - a tactic known as nectar robbing. The spiderhunters are omnivorous. As their name suggests they will eat spiders, and are capable of extracting spiders from the centre of their webs, a tricky task. They also ...
Butterflies receive ultraviolet signals by using a special opsin in the butterfly eye. The butterfly eye is similar to the average insect eye in that it is composed of numerous ommatidia. Each butterfly ommatidium contains nine photoreceptor cells with generally each cell using a single opsin.
