The '''sharp-shinned hawk''' ('''''Accipiter striatus''''') or '''northern sharp-shinned hawk''', commonly known as a '''sharpie''',<ref>{{cite web | url=https://birdfinding.info/sharp-shinned-hawk/ | title=Sharp-shinned Hawk – birdfinding.info | date=16 May 2020 }}</ref> is a small [[hawk]], with males being the smallest hawks in the United States and Canada, but with the species averaging larger than some [[Neotropical realm|Neotropical]] species, such as the [[tiny hawk]]. The [[Taxonomy (biology)|taxonomy]] is far from resolved, with some authorities considering the southern [[taxon|taxa]] to represent three separate species: [[white-breasted hawk]] (''A. chionogaster''), [[plain-breasted hawk]] (''A. ventralis''), and [[rufous-thighed hawk]] (''A. erythronemius'').<ref name=IOC14.1>{{BioRef|IOC|title=Hoatzin, New World vultures, Secretarybird, raptors |url=https://www.worldbirdnames.org/bow/raptors/#1707928385R7706 |version=14.1 |access-date=24 March 2024}}</ref> The [[American Ornithological Society]] and some other checklists keep all four species conspecific.<ref>{{BioRef|avibase|title=Sharp-shinned Hawk ''Accipiter striatus'' Vieillot, LJP 1808  |url=https://avibase.bsc-eoc.org/species.jsp?lang=EN&avibaseid=F2B44500C0E8918E&sec=taxontable |access-date=24 March 2024}}</ref>

==Taxonomy==
[[File:SharpshinnedHawk23.jpg|thumb|With a chick (nominate group)]]
The sharp-shinned hawk is sometimes separated into four species, with the northern group (''see distribution'') retaining both the [[scientific name]] and the [[common name]]: sharp-shinned hawk (''A. striatus'').<ref name=IOC14.1/> In addition to the nominate taxon (''A. s. striatus''), it includes the subspecies ''perobscurus'', ''velox'', ''suttoni'', ''madrensis'', ''fringilloides'', and ''venator''. The three remaining taxa, each considered a [[monotypic]] species if split, are the white-breasted hawk (''A. chionogaster''; [[Johann Jacob Kaup|Kaup]], 1852), plain-breasted hawk (''A. ventralis''; [[Philip Lutley Sclater|Sclater]], 1866) and rufous-thighed hawk (''A. erythronemius''; Kaup, 1850). The breeding ranges of the groups are entirely [[allopatric]], although the wintering range of the nominate group partially overlaps with the range of ''chionogaster'' (as is also the case with certain taxa within the nominate group). This allopatry combined with differences in plumage (see ''Appearance'') and, apparently, certain measurements, has been the background for the split, but hard scientific data are presently lacking ([[American Ornithologists' Union|AOU]]). Disregarding field guides, most material published in recent years (e.g. AOU, Ferguson-Lees ''et al.'' p.&nbsp;586, and Dickinson ''et al.'') has therefore considered all to be members of a single widespread species – but not without equivocation: Ferguson-Lees et al. say that if they were to make a world list, they would include the three taxa as separate species (p.&nbsp;75), and the AOU's comment includes the note "split almost certainly good".

Storer (1952) suggested that the southernmost populations within the nominate group were paler below, thus approaching ''chionogaster''. This has also been reflected in recent guides, where ''A. s. madrensis'' of southern Mexico is described as being relatively pale below (compared to more northern subspecies), but if this is a sign of [[intergradation]] with ''chionogaster'' or a north-south cline which includes both the members of the nominate group and ''chionogaster'' remains unclear. In Bolivia, ''ventralis'' and '' erythronemius'' approach each other, but no evidence of intergradation is known – something that, without actual [[Biological specimen|specimen]]s, also would be hard to prove due to the variability in the plumage of ''ventralis''.

A 2021 study of sharp-shinned hawks recommended recognising the three endemic Caribbean island subspecies as distinct species, based on analysis of nuclear and mitochondrial DNA and diagnosed by their plumage: ''A. striatus'', restricted to the island of Hispaniola, ''A. fringilloides'' to Cuba and ''A. venator'' to Puerto Rico. If this is accepted and ''A. striatus'' treated as endemic to Hispaniola, the continental complex would take the scientific name ''A. velox''.<ref>{{cite journal |last1=Catanach |first1=Therese A. |last2=Halley |first2=Matthew R. |last3=Allen |first3=Julie M. |last4=Johnson |first4=Jeff A. |last5=Thorstrom |first5=Russell |last6=Palhano |first6=Samantha |last7=Poor Thunder |first7=Chyna |last8=Gallardo |first8=Julio C. |last9=Weckstein |first9=Jason D.  |title=Systematics and conservation of an endemic radiation of ''Accipiter'' hawks in the Caribbean islands |date=2021  |journal=Ornithology |volume=138 |issue=3 |doi=10.1093/ornithology/ukab041 |url=https://academic.oup.com/auk/article-pdf/138/3/ukab041/38893090/ukab041.pdf}}</ref>

==Description==
{{more citations needed section|date=April 2016}}
This is a small ''[[Accipiter]]'' hawk, with males {{convert|23|to|30|cm|in|abbr=on}} long, with a wingspan of {{convert|42|to|58|cm|in|abbr=on}} and weight from {{convert|82|-|115|g|oz|abbr=on}}. As common in ''Accipiter'' hawks, females are distinctly larger in size, averaging some 30% longer, and with a weight advantage of more than 50% being common. The female measures {{convert|29|to|37|cm|in|abbr=on}} in length, has a wingspan of {{convert|58|to|68|cm|in|abbr=on}} and weighs {{convert|150|to|219|g|oz|abbr=on}}. The wings measure {{convert|14.1|-|22.9|cm|in|abbr=on}} each, the tail is {{convert|12|-|19|cm|in|abbr=on}} long and the tarsus is {{convert|4.5|-|5.9|cm|in|abbr=on}}. Measurements given here are for the northern group, but they are comparable for the remaining subspecies.<ref>''Raptors of the World'' by Ferguson-Lees, Christie, Franklin, Mead, and Burton. Houghton Mifflin (2001), {{ISBN|0-618-12762-3}}</ref> Adults have short broad wings and a medium-length tail banded in blackish and gray with the tip varying among individuals from slightly notched<ref>{{cite book|author1=Chandler S.

The [[remiges]] (typically only visible in flight) are whitish barred blackish. The legs are long and very slender (hence the common name) and yellow. The hooked bill is black and the [[cere]] is yellowish. The remaining plumage varies depending on group:

* Nominate group: Cap dark and upperparts blue-grey (the former darker). Often, a few more-or-less random white spots can be seen on the scapulars (feathers attached to the wing that cover the meeting of wing and body). Underparts white with rufous or [[Tawny (color)|tawny]] bars. The crissum (the undertail [[Covert feather|coverts]] surrounding the [[cloaca]]) is white. Thighs rufous, but often barred white. The cheeks are tinged rufous (sometimes faint, but generally very distinct in taxa from the Greater Antilles). The [[Iris (anatomy)|irides]] are dark orange to red, but these are yellowish to pale orange in [[Juvenile (organism)|juveniles]]. Juveniles have dark brownish upperparts, each feather edged rufous, giving a rather scaly appearance. The brown head is streaked whitish, and the whitish underparts are extensively streaked brown or reddish and usually with reddish barring on the sides.

[[File:Sharp-shinned Hawk, Fort Collins, CO.jpg|thumb|Sharp-shinned Hawk, Fort Collins, Colorado]]

* ''A. (s.) chionogaster'' (white-breasted hawk): Resembles the members of the nominate group, but upperparts darker (often appears almost black), thighs whitish-buff and underparts and cheeks entirely white. Juveniles have darker upperparts and distinctly finer streaking below than juveniles of the nominate group.
* ''A. (s.) ventralis'' (plain-breasted hawk): [[Polymorphism (biology)|Polymorphic]]. The most common morph has dark grey upperparts (often appears almost black) and white underparts variably barred, shaded, or mottled with rufous or tawny-[[Buff (colour)|buff]] (extensively marked individuals may appear almost entirely rufous or tawny-buff below). Occasionally, the barring to the lower belly and flanks may appear duskier. The white morph has bluish-grey upperparts (similar to the nominate group), but its underparts are all white except for its rufous thighs. The rare dark morph, the only morph which sometimes lacks rufous thighs, is entirely sooty (occasionally with slight white barring to belly and faint grey bands in tail). The underparts of the females average paler than males of the same morph. The iris is typically yellow (''contra'' illustrations in some books), but individuals (mainly sub-adults?) with a darker iris are occasionally seen. Juveniles have dark brownish or dusky upperparts with each feather typically edged rufous, giving a rather scaly appearance. The underparts are white streaked brown, and the thighs are rufous barred white. Occasionally, juveniles with underparts extensively rufous streaked blackish are seen.
* ''A. (s.) erythronemius'' (rufous-thighed hawk): Resembles the nominate group, but upperparts darker, streaking to underparts rufous or dusky, cheeks typically with a clear rufous patch (occasionally lacking almost entirely) and iris yellow (''contra'' illustrations in some books). Juveniles resemble juveniles of the nominate group, but streaking to underparts typically restricted to throat and central underparts, with flanks scaled or barred (often also belly).

==Distribution==
This species is widespread in [[North America]], [[Central America]], [[South America]] and the [[Greater Antilles]]. Below, the distributions of the four groups (see ''Taxonomy'') are described as they occur roughly from north to south:

* The nominate (''A. s. striatus'') group is widespread in [[North America]], occurring in all of the forested part of USA and Canada, breeding in most of it. Populations in the northern part of the range [[Bird migration|migrate]] south and spend the non-breeding season (winter) in the southern USA, [[Mexico]] and Central America as far south as [[Panama]], with a smaller number spending the winter in the Greater Antilles. [[Resident bird|Resident]] populations exist in [[temperate]] parts of the US, [[Canada]] (in a few coastal regions), Mexico (highlands from [[Sonora]] to [[Oaxaca]]), [[Cuba]], [[Hispaniola]] and [[Puerto Rico]].
* ''A. (s.) chionogaster'' (white-breasted hawk) occurs in highlands from far southern Mexico ([[Chiapas]] and [[Oaxaca]]), through [[Honduras]], [[Guatemala]] and [[El Salvador]], to [[Nicaragua]]. It is, as far as known, resident, but some local movements may occur.
* ''A. (s.) ventralis'' (plain-breasted hawk) occurs in the coastal mountains of northern [[Venezuela]] and [[Colombia]], south through the [[Andes]] from western Venezuela, through Colombia, [[Ecuador]] and [[Peru]], to central [[Bolivia]]. A [[Disjunct distribution|disjunct]] population occurs in the [[Tepui]]s of southern Venezuela (likely to extend into adjacent parts of [[Roraima]] in far northern [[Brazil]], but this remains unconfirmed). It is, as far as known, resident, but some local movements may occur.
* ''A. (s.) erythronemius'' (rufous-thighed hawk) is widespread in eastern [[South America]] in eastern and southern Brazil, [[Uruguay]], [[Paraguay]], north-eastern [[Argentina]] and south-eastern Bolivia. It is, as far as known, resident in some regions and migratory in others. The movements are generally poorly understood, but it only occurs seasonally at some localities in Argentina.

==Habitat==

It occurs in a wide range of woodland and forest types, both dominated by [[conifer]]s and by various types of [[broad-leaved tree]]s (especially [[oak]]s) The largest populations of the nominate group (''see taxonomy'') are thought to occur in the [[temperate]] [[boreal forests]], but winter in warmer regions farther south (''see distribution''). The [[taxa]] ''suttoni'', ''madrensis'' (both from the nominate group), ''chionogaster'' (white-breasted hawk) and ''ventralis'' (plain-breasted hawk), are found in upper [[tropical]] to temperate highlands; mainly at altitudes of {{convert|300|–|3000|m|ft|abbr=on}}, but occasionally down to near [[sea-level]] and up to {{convert|4000|m|ft|abbr=on}}. The taxon ''erythronemius'' (rufous-thighed hawk) is found in tropical and subtropical regions; both in lowlands and highlands.

These birds surprise and capture most of their prey from cover or while flying quickly through dense vegetation. They are adept at navigating dense thickets, although this hunting method is often hazardous to the hawk. The great majority of this hawk's prey are small birds, especially various [[songbird]]s such as [[Old World sparrow|sparrow]]s, [[New World warbler|wood-warblers]], [[finch]]es, [[wren]]s, [[nuthatch]]es, [[Tit (bird)|tits]], [[icterid]]s and [[thrush (bird)|thrushes]]. Birds caught range in size from a {{convert|4.4|g|oz|abbr=on}} [[Anna's hummingbird]] to a {{convert|577|g|lb|abbr=on}} [[ruffed grouse]] and virtually any bird within this size range is potential prey. Typically, males will target smaller birds, such as sparrows and wood-warblers, and females will pursue larger prey, such as [[American robin]]s and [[Colaptes|flickers]], leading to a lack of conflict between the sexes for prey. These hawks often exploit backyard bird feeders in order to target congregations of ideal prey. They often pluck the feathers off their prey on a post or other perch. Rarely, sharp-shinned hawks will also eat rodents, lizards, frogs, snakes, and large insects, the latter typically being dragonflies captured on the wing during the hawk's migration. [[Bat]]s have occasionally been recorded as a prey of this hawk.<ref>{{cite journal|last1=Mikula|first1=P.|last2=Morelli|first2=F.|last3=Lučan|first3=R. K.|last4=Jones|first4=D.

[[File:Female Sharp-shinned Hawk with prey (Starling).jpg|thumb|]]

===Reproduction===
[[File:Sharp-Shinned.jpg|thumb|Immature (nominate group)]]
Sharp-shinned hawks construct a stick nest in a large [[conifer]] or dense group of [[deciduous]] trees. Clutches of 3 to 8 eggs have been recorded, but 4 to 5 eggs is the typical clutch size. The eggs measure {{convert|37.6|x|30|mm|in|abbr=on}} and weigh about {{convert|19|g|oz|abbr=on}}. The eggs are prized by egg-collectors, because they are heavily marked with surprisingly colorful and varied markings. The incubation period is thought to average at about 30 days. After hatching, the young are brooded for 16 to 23 days by the female, while the male defends the territory and catches prey. The young fledge at the age of about a month and rely on their parents for feeding and protection another four weeks. The nesting sites and breeding behavior of sharp-shinned hawks are generally secretive, in order to avoid the predation of larger raptors, such as the [[American goshawk]] and the [[Cooper's hawk]]. While in migration, adults are sometimes preyed on by most of the bird-hunting, larger raptors, especially the [[peregrine falcon]]. The breeding behavior of the taxa ''chionogaster'' (white-breasted hawk), ''ventralis'' (plain-breasted hawk) and ''erythronemius'' (rufous-thighed hawk) are comparably poorly known, but based on the available knowledge they appear to differ little from that of the nominate group

==Conservation==
[[File:Puerto Rican Sharp-shinned hawk perched on tree limb.jpg|upright|thumb|right|Endangered subspecies ''venator'', endemic to [[Puerto Rico]]]]
In North America this species declined in numbers in the 1960s and 1970s, probably as a result of the use of [[DDT]] and other [[pesticides]]. The population of USA and Canada has rebounded since and might even exceed historical numbers today, probably due to the combination of the ban on DDT and the proliferation of backyard bird feeders in North America which create unnaturally reliable and easy prey sources. Migratory sharp-shinned hawks are one of the most numerous raptors recorded at "hawk watches" across the country. An exception is the [[subspecies]] from [[Puerto Rico]], ''[[Accipiter striatus venator]]'', which is rare and listed as [[endangered]] by the [[U.S. Fish & Wildlife Service]]. The remaining resident subspecies from the Greater Antilles, ''fringilliodes'' from Cuba and nominate (''A. s. striatus'') from Hispaniola, are uncommon, local, and, at least in the case of the latter, decreasing. Both ''ventralis'' (plain-breasted hawk) and ''erythronemius'' (rufous-thighed hawk) are fairly common (but easily overlooked due to their secretive behavior) and presently considered safe. The situation for ''chionogaster'' (white-breasted hawk) is potentially more problematic due to its limited range, although it, at least locally, remains fairly common.
