Wrentit
Chamaea fasciata
A plump, large-headed, brownish bird with an extremely long tail. Plain overall with no distinctive plumage features; look for pale eye and stubby bill. Difficult to see, but often heard giving an accelerating series of hard chip notes. Usually solitary or in pairs. Skulks through low, dense vegetation, especially chaparral. Restricted to the Pacific coast of North America, from Oregon to northern Baja. Not closely related to any other species in the Western Hemisphere. Might be confused with Bushtit, but larger and much different behavior and vocalizations.
Identification
The wrentit is a small, 15 cm (5.9 in) bird with uniform dull olive, brown, or grayish plumage. It has short wings and a long tail often held high (hence the comparison to wrens). It has a short bill and a pale iris. Given its retiring nature and loud voice, the wrentit is more likely to be detected by its call than by sight. The distinct sound that it makes is similar to the sound of a ping-pong ball falling on the table.
Taxonomy
The wrentit has been variously placed in its own family, the Chamaeidae, or with the long-tailed tits (Aegithalidae), the true tits and chickadees (Paridae), the "Old World warblers" (Sylviidae), and with the "Old World babblers" (Timaliidae). The American Ornithologists' Union places the wrentit in the latter family, giving it the distinction of being the only babbler known from the New World. This is based on DNA–DNA hybridization studies, which are phenetic, however, and therefore not considered methodologically adequate today.[citation needed]<p>Through DNA sequence analysis, it was subsequently discovered that the wrentit was more closely allied to Sylvia warblers and some aberrant "babblers". These consequently must be placed in the family Sylviidae together with the wrentit and the parrotbills which also turned out to be close relatives. Thus, the wrentit is the only American species of the "true" or sylviid warblers. Peculiarly, the Dartford warbler and close relatives like Marmora's warbler bear an uncanny resemblance to the wrentit; their ecology is quite similar indeed, as all are birds of Mediterranean scrub. However, biogeography and the molecular data build a strong case for this similarity being a case of convergent evolution between birds that are close relatives but by far not as close as their appearance would suggest.<p>Alice Cibois suggested that as some babblers are closer to typical warblers than these are to marsh-warblers for example, the Sylviidae should be merged into the Timaliidae. As such an abolishing of the senior synonym would require a formal International Commission on Zoological Nomenclature ruling and the typical warblers and relatives are still a monophyletic group at present, this proposal is not advanced by most researchers until the remaining Sylviidae and Timaliidae genera are studied as regards their relationships.[citation needed]<p>In 2019, a major taxonomic revision of species formerly classified as "babblers" recovered Chamaea as being most closely allied with the parrotbills and fulvettas, which are otherwise an exclusively Asian group. Due to their phylogenetic and morphological distinctiveness, the family Paradoxornithidae was revived for this group, including the wrentit.

Range and habitat
The wrentit is a sedentary (non-migratory) resident of a narrow strip of coastal habitat along the western coast of North America, being found from Oregon south through California, to Baja California, the northern state of the Baja California peninsula.<p>It is usually restricted to certain chaparral and woodland habitats. It nests in 1 metre (3 ft) high shrubs such as poison oak (Toxicodendron diversilobum), coyote bush (Baccharis pilularis) and California blackberry (Rubus ursinus). Logging and other changes in habitat have led to this species expanding its range recently, particularly northwards.

Behavior
Wrentits mate for life, forming pair bonds only a few months after hatching. Both sexes sing; the faster rhythm of the male's song is one of the few ways to differentiate the sexes. Both sexes also defend their territory year-round and participate in building the nest, a four-stage process that takes about two weeks. The three or four eggs are incubated for 14 days, again by both sexes. The chicks fledge after 15 days (at which stage they are unable to fly) and are fed by their parents for another 40 days.<p>The wrentit feeds by skulking through dense scrub gleaning exposed insects found by sight. It feeds primarily on beetles, caterpillars, bugs, and ants, but also takes small berries and seeds.

Southern Crested Guineafowl
Guttera edouardi
A large-bodied, small-headed, black gamebird perfectly lined with rows of hundreds of bluish-white spots. It has a ridiculous-looking plumed “toupee” above the naked face, which features an ivory-colored bill and a blood-red eye. The facial skin color varies geographically, and can be mostly blue-gray with small patches of red and white, or predominantly blue-gray with a large white patch on the back of the neck. A broad band around the base of the neck is unspotted black. It prefers forest and thickets, where it forages on the ground for berries, seeds, and other plant matter. The similar Helmeted Guineafowl differs by its lack of feathered crest and its having a bone-like casque on top of the head instead. The alarm call is a series of rattling, agitated notes that speed up and slow down; similar to the call of Helmeted Guineafowl, but with a tinnier quality.
Pennant-winged Nightjar
Caprimulgus vexillarius
Breeding males have extraordinary “pennants” growing out of their wings. Non-breeding males are still distinctive due to the huge white patches on the wings. Females are very drab, and lack white in the wing or tail, unlike most nightjars. This is a migratory species that is found in many different habitats on migration and during the non-breeding season. Breeds in moist savanna and broadleaved woodland, especially miombo. Song is a slow, squeaky trill. Female is similar to Standard-winged Nightjar, but is larger and has more barring in the wings.
Tui
Prosthemadera novaeseelandiae
A large, dark nectar feeder endemic to New Zealand. Easily distinguished by two curled white feather tufts (“poi”) visible on the throat. Tail and wings have blue, purple, and green iridescence. Found throughout much of New Zealand, including Auckland, Kermadec, and Chatham Islands, though mostly absent from Canterbury. Favors native forest and scrub, also venturing into suburban parks, farmland, and rural gardens. Often detected by its unique voice consisting of melodious notes intermixed with croaks, coughs, clicks, and wheezes. Also listen for its noisy whirring flight. Similar to male Eurasian Blackbird, but easily identified by its white throat feathers and iridescence. Song can be easily confused with that of a bellbird, but listen for distinct loud coughs, grunts, and wheezes in Tui song.
