The yellow warbler (''Setophaga petechia'') is a New World warbler species. Yellow warblers are the most widespread species in the diverse genus ''Setophaga'', breeding in almost the whole of North America, the Caribbean, and down to northern South America.
Family Parulidae

They weigh , varying between subspecies and whether on migration or not, globally averaging about but only in most breeding adults of the United States populations. Among standard measurements throughout the subspecies, the Wing chord (biology), wing chord is , the tail is , the Beak, bill is and the Tarsus (skeleton), tarsus is . The summer males of this species are generally the yellowest warblers wherever they occur. They are brilliant yellow below and greenish-golden above. There are usually a few wide, somewhat washed-out rusty-red streaks on the breast and flanks. These markings are the reason for the scientific name ''petechia'', which roughly translates to "liver spotted". The subspecies in this group mostly vary in brightness and size according to Bergmann's Rule, Bergmann's and Gloger's Rule. The golden warbler (''petechia'' group; 17 subspecies) is generally resident in the mangrove swamps of the West Indies. Local seasonal migrations may occur. On the Cayman Islands for example, ''S. p. eoa'' was found to be "decidedly scarce" on Grand Cayman and apparently absent from Cayman Brac in November 1979, while it had been a "very common" breeder in the group some ten years before, and not frequently seen in the winters of 1972/1973; apparently, the birds disperse elsewhere outside the breeding season. The Cuban golden warbler (''S. p. gundlachi'') barely reached the Florida Keys where it was first noted in 1941, and by the mid-20th century a breeding population was resident. Though individual birds may stray farther north, their distribution is restricted by the absence of mangrove habitat. They are generally smallish, usually weighing about or less and sometimes as little as . The summer males differ from those of the yellow warbler in that they have a rufous crown, hood or mask. The races in this group vary in the extent and hue of the head patch. The mangrove warbler (''erithachorides'' group; 12 subspecies) tends to be larger than other yellow warbler subspecies groups, averaging in length and in weight. It is resident in the mangrove swamps of coastal Middle America and northern South America; ''S. p. aureola'' is found on the oceanic Galápagos Islands. The summer males differ from those of the yellow warbler in having a rufous hood or crown. The races in this group vary in the extent and hue of the hood, overlapping extensively with the golden warbler group in this character. The American yellow warbler (''aestiva'' group; 6 subspecies) breeds in the whole of temperate North America as far south as central Mexico in open, often wet, woods or shrub. It is bird migration, migratory, wintering in Central America, Central and South America. They are very rare vagrants to western Europe and Scandinavia

American yellow warblers breed in most of North America from the tundra southwards, except for the far Southwest and the Gulf of Mexico coast. American yellow warblers winter to the south of their breeding range, from southern California to the Amazon Basin, Amazon region, Bolivia and Peru. The mangrove and golden warblers occur to the south of it, to the northern reaches of the Andes.
American Yellow Warblers arrive in their breeding range in late spring – generally about April/May – and move to winter quarters again starting as early as July, as soon as the young are fledged. Most, however, stay a bit longer; by the end of August, the bulk of the northern populations has moved south, though some may linger almost until fall. At least in northern Ohio, yellow warblers do not linger, leaving as they did 100 years ago.
The breeding habitat of American yellow warblers is typically riparian or otherwise moist land with ample growth of small trees, in particular willows (''Salix''). The other groups, as well as wintering birds, chiefly inhabit mangrove swamps and similar dense woody growth. Less preferred habitat are shrubland, farmlands and forest edges. In particular American yellow warblers will come to suburban or less densely settled areas, orchards and parks, and may well breed there. Outside the breeding season, these warblers are usually encountered in small groups, but while breeding they are fiercely territory (biology), territorial and will try to chase away any conspecific intruder that comes along.
Roughly 60% of their diet is caterpillars. They also consume wasps, mayflies, moths, mosquitoes, beetles, damselflies, treehoppers, other insects, insect larvae, and spiders. They acquire prey by Gleaning (birds), gleaning in shrubs and on tree branches, and by Hawking (birds), hawking prey that tries to fly away. Other invertebrates and some berries and similar small juicy fruits are also eaten, the latter especially by American yellow warblers in their winter quarters. The yellow warbler is one of several insectivorous bird species that reduce the number of Hypothenemus hampei, coffee berry borer beetles in Costa Rica coffee plantation
by 50%
Caterpillars are the staple food for nestlings, with some – e.g. those of geometer moths (Geometridae) – preferred over others. The predators of yellow and mangrove warblers are those typical of such smallish tree-nesting passerines, such as snakes, foxes, birds of prey, and many others. The odds of an adult American yellow warbler surviving from one year to the next are on average 50%; in the southern populations, by contrast, about two-thirds of the adults survive each year. Conversely, less than one American yellow warbler nest in three on average suffers from predation in one way or another, while two out of three mangrove and golden warbler nests are affected.Bachynski & Kadlec (2003), Salgado-Ortiz ''et al.'' (2008) Snakes, including the Coluber constrictor, blue racer (''Coluber constrictor foxii'') and common garter snake (''Thamnophis sirtalis''), are significant nest predators, taking nestlings and Fledgling (birds), fledglings as well as sick or distracted adults. Likewise, corvids such as the American crow (''Corvus brachyrhynchos'') and blue jay (''Cyanocitta cristata''),E.g. : Bachynski & Kadlec (2003) and large climbing rodents, notably the American red squirrel (''Tamiasciurus hudsonicus'') also attack nests in this manner. Carnivora, Carnivores (in particular members of the Musteloidea) including the striped skunk (''Mephitis mephitis''), long-tailed weasel (''Neogale frenata''), common raccoon (''Procyon lotor''), red fox (''Vulpes vulpes''), and domestic cat, domestic or feral cats, are similarly opportunistic predators. All these pose little threat to the nimble, non-nesting adults, which are taken by certain smallish and agile birds such as the American kestrel (''Falco sparverius'') and Cooper's hawk (''Accipiter cooperii''), and the sharp-shinned hawk (''A. striatus''). Other avian predators of adults have included peregrine falcons (''Falco peregrinus'') and Merlin (bird), merlins (''F. columbarius''). Owls such as great horned owls (''Bubo virginianus'') and eastern screech owls (''Megascops asio'') have been known to assault yellow warblers of all ages at night. These New World warblers seem to mobbing behaviour, mob predators only rarely. An exception are cowbirds, which are significant brood parasites. The yellow warbler is a regular host of the brown-headed cowbird (''Molothrus ater''), with about 40% of all nests suffering attempted or successful parasitism. By contrast, the tropical populations are less frequent hosts to the shiny cowbird (''M. bonariensis''), with only 10% of nests affected. This may be due to the slightly larger size of shiny cowbirds, which are less likely to survive being fed by the much smaller warbler, compared to brown-headed cowbirds. The yellow warbler is one of the few passerine proven to be able to recognize the presence of cowbird eggs in its nest. Upon recognizing one the warbler will often smother it with a new layer of nesting material. It will usually not try to save any of its own eggs that have already been laid, but produce a replacement clutch (eggs), clutch. Sometimes, the parents desert a parasitized nest altogether and build a new one. Unlike some cuckoos, cowbird nestlings will not actively kill the nestlings of the host bird; mixed broods of ''Setophaga'' and ''Molothrus'' may fledge successfully. However, success of fledging in yellow warbler nests is usually decreased by the parasitism of cowbirds due to the pressures of raising a much larger bird. Other than predation, causes of Death, mortality are not well known. The maximum recorded ages of wild yellow warblers are around 10 years. A wintering American yellow warbler examined near Turbo, Colombia was not infected with blood parasitism, parasites, unlike other species in the study. It is unclear whether this significant, but wintering birds in that region generally lacked such parasites.
As usual for members of the ''Parulidae'', yellow warblers nest in trees, building a small but very sturdy cup nest. Females and males rear the young about equally, but emphasize different tasks: females are more involved with building and maintaining the nest, and incubating and brooding the offspring. Males are more involved in guarding the nest site and procuring food, bringing it to the nest and passing it to the waiting mother, which does most of the actual feeding. As the young approach fledging, the male's workload becomes proportionally higher.
The American yellow and mangrove (including golden) warblers differ in some other reproductive parameters. While the former is somewhat more of an r-strategist, the actual differences are complex and adaptation, adapted to different environmental conditions. The yellow warbler starts breeding in May/June, while the mangrove warbler breeds all year round. American yellow warblers have been known to raise a brood of young in as little as 45 days, with 75 the norm. Tropical populations, by contrast, need more than 100 days per breeding. Males court the females with songs, singing 3,200 or more per day. They are, like most songbirds, generally serial monogamy, serially monogamous; some 10% of mangrove warbler and about half as many American yellow warbler males are bigamous. Very few if any American yellow warblers breed more than once per year, with just 5% of female mangrove warblers doing so. If a breeding attempt fails, either parent will usually try to raise a second brood.
The clutch (eggs), clutch of the American yellow warbler is 3–6 (typically 4–5, rarely 1–2) eggs. Avian incubation, Incubation usually takes 11 days, sometimes up to 14. The nestlings weigh on average, are brooding, brooded for an average 8–9 days after hatching, and leave the nest the following day or the one thereafter. The mangrove warbler has only 3 eggs per clutch on average and incubates some 2 days longer. Its average post-hatching brooding time is 11 days. Almost half of the parents (moreso in the mangrove warbler than the American yellow warbler) attend the fledglings for two weeks or more after these leave the nest. Sometimes the adults separate early, each accompanied by one to three of the young.Bachynski & Kadlec (2003), Salgado-Ortiz ''et al.'' (2008), AnAge [2009]
Some 3–4 weeks after hatching, the young are fully independent of their parents. They become sexually mature at one year of age, and attempt to breed right away. Some 55% of all American yellow warbler nestings are successful in raising at least one young. In contrast, only 25% of mangrove warbler nests successfully fledge any offspring, with accidents and predator, predation frequently causing total loss of the clutch.

Etymology
The genus name ''Setophaga'' is from Ancient Greek ''ses'', "moth", and ', "eating", and the specific ''petechia'' is from Italian ''petecchia'', a small red spot on the skin. The American yellow warbler is sometimes colloquially called the "summer yellowbird".Description and taxonomy
Other than in male plumage, breeding plumage and body size, all warbler subspecies are very similar. Winter, female and immature birds all have similarly greenish-yellow uppersides and are a duller yellow below. Young males soon acquire breast and, where appropriate, head coloration. Females are somewhat duller, most notably on the head. In all, the flight feather, remiges and flight feather, rectrices are blackish olive with yellow edges, sometimes appearing as an indistinct wing-band on the former. The eyes and the short thin beak are dark, while the feet are lighter or darker olive-buff (colour), buff.Bachynski & Kadlec (2003)Curson ''et al.'' (1994) The 35 subspecies of ''S. petechia'' can be divided into three main groups according to the males' head color in the breeding season. Each of these groups is sometimes considered a separate species, or the ''aestiva'' group (yellow warbler) is considered a species different from ''S. petechia'' (mangrove warbler, including golden warbler); the latter option is the one currently accepted by the International Ornithological Congress ''World Bird List''.IOC World Bird LisFamily Parulidae

Vocalizations
The song is a musical strophe that can be rendered ''sweet sweet sweet, I'm so sweet'', although it varies considerably between populations. The call is a soft or harder ''chip'' or ''ship''. This is particularly frequently given by females after a male has finished his song. In territory (biology), territorial defense, they give hissing calls, while ''seet'' seems to be a kind of specialized cowbird alert (#Breeding, see below). Other calls are given in communication between pair-members, neighbors, or by young begging for food. These birds also communicate with postures and perhaps with touch.Ecology

Status and conservation
Yellow warblers, in particular the young, devour many pest (organism), pest insects during the breeding season. The plumage and song of the breeding males have been described as "lovely" and "musical", encouraging ecotourism. No significant negative effects of American yellow and mangrove warblers on humans have been recorded. Being generally common and occurring over a wide range, the yellow warbler is not considered a threatened species by the IUCN. Some local decline in numbers has been found in areas, mainly due to habitat destruction and pollution. The chief causes are land clearance, the agriculture, agricultural overuse of and herbicide and pesticide, and sometimes overgrazing. However, stocks will usually rebound quickly if riparian habitat is allowed to recover, particularly among the prolific American yellow warbler. The North American populations are legally protected by the Migratory Bird Treaty Act. The Barbados golden warbler (''D. p. petechia'') has been listed as "endangered foreign wildlife" by the United States' Endangered Species Act (ESA) since 1970; other than for specially permitted scientific, educational or conservation purposes, importing it into the USA is illegal. The Californian yellow warbler (''D. p./a. brewsteri'') and Sonoran yellow warbler (''D.p./a. sonorana'') are listed as "species of concern" by the ESA.Bachynski & Kadlec (2003), USFWS (1970, 2009abc)Footnotes
