I was wondering if someone could help me identify this hawk (taken yesterday, Sept. 2, 2019, in Cumberland, Rhode Island). Indeed, the merlin seems to represent a lineage distinct from other living falcons since at least the Early Pliocene, some 5 Ma (million years ago). Smaller birds will generally avoid a hunting merlin if possible. Then it took off to fly in circles in the sky and cry some more. If you are trying to identify a hawk that may be a Cooper's Hawk or a Sharp-shinned Hawk, check out our Sharp-shinned Hawk vs. Cooper's Hawk page. Feeding mostly on birds and small mammals, it hunts by stealth, approaching its prey through dense cover and then pouncing with a rapid, powerful flight. These secretive birds are mostly gray with bold white “eyebrow” stripes over piercing orange to red eyes. Males typically have wingspans of 53–58 centimetres (21–23 in), with females being slightly larger. Breeding pairs will frequently hunt cooperatively, with one bird flushing the prey toward its mate. The American Kestrel’s flight is batty and flat, for example, while the Merlin’s wing beats are fast, powerful, and piston-like. Aesalon columbarius (Linnaeus, 1758) Arguably, they might be considered distinct species, with gene flow having ceased at least a million years ago, but probably more. The migration to the breeding grounds starts in late February, with most birds passing through the US, Central Europe and southern Russia in March and April, and the last stragglers arriving in the breeding range towards the end of May. Each wing measures 18.2–23.8 cm (7.2–9.4 in), the tail measures 12.7–18.5 cm (5.0–7.3 in) and the tarsus measures 3.7 cm (1.5 in).

[8], "Merlin Overview, All About Birds, Cornell Lab of Ornithology", "A preliminary list of the birds of Seneca County, Ohio", "Phylogeny of the Falconidae inferred from molecular and morphological data", "The Meade Basin Rodent Project; a progress report. It’s an accipiter—a type of hawk with short, broad wings and a long rudderlike tail that give it superb aerial agility. [8][22], In particular during the breeding season, most of the prey are smallish birds weighing 10–40 g (0.35–1.41 oz). [1][8], By far the most serious long-term threat to these birds is habitat destruction, especially in their breeding areas. We had just gotten done seeing the Merlin at close range when I noticed something eating in the mud. Most of its populations are migratory, wintering in warmer regions. It feeds mostly on small birds, capturing them in mid-air in rapid pursuit. The red-necked falcon is sometimes considered more closely related to the merlin than other falcons, but this seems to be a coincidence due to similar hunting habits; it could not be confirmed in more recent studies. In the United States, chickenhawk or chicken hawk is an unofficial designation for three species of North American hawks in the family Accipitridae: Cooper's hawk, also called a quail hawk, the sharp-shinned hawk, and the red-tailed hawk.The term "chicken hawk", however, is inaccurate. [8], In North America, the species seems to have been more widespread in the past, or perhaps its range has shifted northwards: F. c. columbarius was an uncommon breeding bird in Ohio before the 20th century, but in Seneca County, as early as the 1900s even single adults were rarely seen in the breeding season.

In the milder maritime parts of its breeding range, such as Great Britain, the Pacific Northwest and western Iceland, as well as in Central Asia, it will merely desert higher ground and move to coasts and lowland during winter. in Ohio, just south of the breeding range, F. c. columbarius is typically recorded as a southbound migrant as late as September/October. Kestrels float when they glide; the heavier Merlins sink. [9][12][16], That the merlin has a long-standing presence on both sides of the Atlantic is evidenced by the degree of genetic distinctness between Eurasian and North American populations.

Next, I get many questions dealing with a certain race of buteos the Western Red-tailed Hawk and Harlan's. After adapting to its ecological niche, ancient merlins would have spread to Eurasia again, with gene flow being interrupted as the Beringia and Greenland regions became icebound in the Quaternary glaciation. In the north of South Asia, wintering males may be confused with the red-necked falcon (F. chicquera) if they fly away from the observer and the head (red on top in F. chicquera) and underside (finely barred with black in F. chicquera) are not visible. I did a similar comparison of a Red-tailed Hawk and an American Kestrel last December. So I thought I would do a post on these to help answer those questions.

A large and exceptionally aggressive female merlin may take prey as large as pigeons and occasionally even small ducks. Overall, merlin stocks appear globally stable; while they may decline temporarily in places, they will usually increase again eventually, suggesting that this phenomenon is due to the fluctuations of supplementary food stocks discussed above. The Merlin is just a wee bit larger than a Kestrel. Almost any such species will be taken, with local preferences for whatever is most abundant—be it larks (Alaudidae), pipits (Anthus) or house sparrows (Passer domesticus)—and inexperienced yearlings always a favorite.
