Red-eyed Vireo
Vireo olivaceus
Plain olive-green above and whitish below with no wingbars. Red eye of adults is not always easy to see; immatures have brown eyes. Dark stripe through and above eye. Larger and thicker-billed than warblers. Breeds in mature deciduous forest. Often sings nearly nonstop throughout the day; listen for repetitive musical phrases coming from the treetops. Often with flocks of chickadees and warblers during migration. Winters in South America, where it could be confused with the very similar Chivi Vireo, from which it is best distinguished by voice.

行为
The breeding habitat of the red-eyed vireo is in the open wooded areas across Canada and the eastern and northwestern United States. These birds migrate to South America, where they spend the winter. The Latin American population occur in virtually any wooded habitat in their range. Most of these are residents, but the populations breeding in the far southern part of this species' range (e.g. most of its range in Argentina, Uruguay, Paraguay and Bolivia) migrate north as far as Central America.<p>In northern Ohio, it seems to return to breed at about the same time as one century ago; but it may leave for winter quarters one or two weeks earlier at present than it did in the past.<p>Red-eyed vireos glean insects from tree foliage, favouring caterpillars and aphids and sometimes hovering while foraging. In some tropical regions, they are commonly seen to attend mixed-species feeding flocks, moving through the forest higher up in the trees than the bulk of such flocks.<p>They also eat berries, especially before migration, and in the winter quarters, where trees bearing popular fruit like tamanqueiro (Alchornea glandulosa) or gumbo-limbo (Bursera simaruba) will even attract them to parks and gardens. Fruit are typically not picked up from a hover, but the birds often quite acrobatically reach for them, even hanging upside down.<p>The nest is a cup in a fork of a tree branch. The red-eyed vireo suffers from nest parasitism by the brown-headed cowbird (Molothrus ater) in the north of its range, and by the shiny cowbird (M. bonariensis) further south. Parasitism by Haemoproteus and trypanosoma might affect these birds not infrequently, as was noted in studies of birds caught in Parque Nacional de La Macarena and near Turbo (Colombia): though only three red-eyed vireos were examined, all were infected with at least one of these parasites.

Red-browed Firetail
Neochmia temporalis
Small waxbill, adult olive green above, gray below, with red eyebrow, red bill, and black tail. In flight, bright red rump apparent. Juvenile with red rump but otherwise olive drab with dark bill. Inhabits grassy areas close to thick cover in eastern and southeastern coastal Australia. Often-heard call is a thin "seeeeep."
Spotted Catbird
Ailuroedus maculosus
Chunky rainforest bird with emerald green upperparts, black spot below the dark red eye, and green-olive underparts with extensive pale spotting. Inhabits the Wet Tropics of northern Queensland (Cairns region), thus does not overlap with similar Green Catbird. Forages mostly in middle and upper story of the rainforest. Compare female and juvenile Satin Bowerbird (with blue eye, darker bill). Spotted Catbird is well known for its characteristic catlike yowling call.
Green White-eye
Zosterops stuhlmanni
A small, sharp-billed warbler-like bird that is saturated with yellow. Note the yellow underparts, olive-yellow back, and bold white spectacles around the eyes. Found in forest, scrub, gardens, moist woodland, and plantations, usually in hyperactive flocks that can contain many individuals. Often joins mixed flocks with other small birds. Most common call is a high-pitched rising rattle. Song is a quiet, chatty sequence of “chew” notes. Similar to Northern Yellow White-eye, but slightly darker and greener, and usually separated by range and habitat. Also similar to Pale White-eye, but usually separated by range; shows more yellow above the bill, is more richly-colored overall, and prefers moister habitats.
