Description

This piece has been featured in the FAA Group, "A Birding Group - Wings".
The sharp-shinned hawk (Accipiter striatus) 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 species, such as the tiny hawk. The taxonomy is far from resolved, with some authorities considering the southern taxa to represent three separate species: white-breasted hawk (A. chionogaster), plain-breasted hawk (A. ventralis), and rufous-thighed hawk (A. erythronemius). The American Ornithological Society keeps all four species conspecific.
Sharp-shinned Hawks are small, long-tailed hawks with short, rounded wings. They have small heads that in flight do not always project beyond the “wrists” of the wings. The tail tends to be square-tipped and may show a notch at the tip. Females are considerably larger than males.
Adults are slaty blue-gray above, with narrow, horizontal red-orange bars on the breast. Immature birds are mostly brown, with coarse vertical streaks on white underparts. Adults and young have broad dark bands across their long tails.
Sharp-shinned Hawks are agile fliers that speed through dense woods to surprise their prey, typically songbirds. They do not stoop on prey from high overhead. They may also pounce from low perches. When flying across open areas they have a distinctive flap-and-glide flight style.
Sharp-shinned Hawks breed in deep forests. During migration, look for them in open habitats or high in the sky, migrating along ridgelines. During the nonbreeding season they hunt small birds and mammals along forest edges and sometimes at backyard bird feeders, causing a wave of high-pitched alarm calls among the gathered songbirds.
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 bars. The crissum (the undertail 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 irides are dark orange to red, but these are yellowish to pale orange in 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.
