Eurasian Skylark – birdfinding.info

Birdfinding.info ⇒ Widespread and common across most of Eurasia’s open spaces from the arctic to subtropical deserts and from Ireland, Portugal, and Morocco to Japan, Kamchatka, and the Bering Sea. Introduced populations are common across Victoria and adjacent areas of southeastern Australia, and throughout New Zealand. In Hawaii, it is common on Maui around Haleakala National Park and Polipoli Spring, and on the Big Island: e.g., Waikoloa Village, Waiki’i Ranch, Pu’u La’au, and South Point. The small British Columbia population is found mainly on the Saanich Peninsula around the Victoria Airport, and in fields along Central Saanich and Island View Roads.

Sometimes regarded as comprising three distinct forms, one mostly European, one pan-Asian, and one limited to Japan, Korea, coastal China, southeastern Russia, and nearby islands—although the basis for these subdivisions is not clear as they overlap geographically and do not appear to be readily distinguishable. In this arrangement, the forms would be distributed approximately as follows:

“European Skylark” (arvensis, scotica, guillelmi, sierrae, harterti, cantarella, and armenica): breeds throughout the western Palearctic from northern Norway and the Faeroe Islands east to the Urals and south to the mountains of northwestern Africa (Morocco to Tunisia), several Mediterranean islands, and southwestern and northeastern Iran.

Partly migratory: in winter northern and eastern populations mostly withdraw from Scandinavia, Russia, and eastern Europe, and move into the general Mediterranean region and Middle East from the Canary Islands east to the Arabian Peninsula and Iran.

Spring migrants regularly overshoot to Iceland. Both northbound and southbound migrants occasionally reach the Azores and Madeira, sometimes in large flocks.

Introduced populations are established across southeastern Australia (Victoria north to the Sydney area and west to coastal South Australia), Tasmania, New Zealand, the Chatham Islands, the main Hawaiian Islands (all except Kauai), and southwestern British Columbia on southern Vancouver Island (and sometimes also on San Juan Island in Washington State). These are thought to have resulted primarily from transplants of arvensis, but introductions of other subspecies may have occurred in some areas.

“Asian Skylark” (pekinensis, lonnbergi, kiborti, and dulcivox): breeds on open plains from the Volga River Valley of south-central Russia and Kazakhstan east to the Bering Sea coastline (to Anadyr), Kamchatka, and the Kurile Islands, south to northern Afghanistan, northernmost Pakistan, western and northeastern China, and the base of the Korean Peninsula.

Highly migratory: western (i.e., central Asian) populations winter across Afghanistan, Pakistan, and northwestern India—likely also on the Arabian Peninsula. Eastern populations winter mainly in central and eastern China—and possibly also Korea, Japan, and Taiwan.

Spring migrants annually overshoot to Alaska’s Bering Sea islands and have bred on the Pribilofs and likely on the outer Aleutian.

Fall vagrants have been recorded in western North America: but in south-coastal Alaska, Oregon, and California. There are also multiple records from the Northwest Chain of Hawaii. In Asia, fall overshoots have been recorded in Singapore and Sabah.

“Japanese Skylark” (japonica and intermedia): breeds throughout Japan and on Sakhalin, the southern Kurile Islands, the Korean Peninsula, Jeju Island, and adjacent coastal areas of southeastern Russia and northwestern China.

Winters in central and southern Japan, the Ryukyu Islands, Taiwan, and southeastern China.

Identification

The generic lark: a plain songbird with streaked brown upperparts and whitish underparts.

Often shows a peaked crest, but when these feathers are not raised its head appears flat-topped or rounded.

The streaking on the upperparts is typically blackish or dark-brown on a pale-brown base. The streaking is especially dense and well-defined on the crown and back, and also continues as a necklace of streaks across the chest.

The facial pattern is dominated by a buffy or brownish cheek and auricular patch, bordered by a pale eyebrow which merges into an indistinct pale eyering. The throat is typically unstreaked and whitish.

The outer tail feathers are white. In flight, the trailing edge of the wing is also white—broadest on the secondaries and noticeable mostly on the upperside.

The bill is sturdy, slightly decurved, and mostly pale but usually has a dark ridge and tip.

The legs are usually pinkish and the hind-toe has an inordinately long claw (a feature it shares with many other lark species). However, leg color is remarkably variable, and can also be orange, yellow, or black.

Regional Variation. Populations vary in the tones of their plumage—but these variations do not appear to correspond closely to the subdivisions among forms that are sometimes recognized (i.e., “European”, “Asian”, and “Japanese”).

Skylark populations from southern and eastern Europe to central Asia (e.g., cantarella, armenica, and dulcivox) tend to be paler than others. Those of eastern Asia (e.g., pekinensis, lonnbergi, and japonica) tend to be darker overall, with warmer shades of brown. Those of northern and western Europe (e.g., scotica and arvensis) tend to be intermediate. However, each region or population seems to include representatives from across the spectrum of plumage tones.

Voice. Song famously exuberant, bouncy, rollicking, rapid-fire torrent of liquid trills, chirps, burbles, and whistles, often reiterating a phrase a few times, then moving to the next. It is typically given in a high, circling flight—actually known as “skylarking”—but sometimes from a perch on the ground: Often incorporates mimicry of other species:Common flight call is a clear, two-syllable chirrup, often repeated:The flight call can also be deep and husky:Sometimes gives a long, sharp whistle, usually in alarm:

Cf. Oriental Skylark. Eurasian and Oriental Skylarks occur together over a long swath of Asia that stretches from Israel to Taiwan. The differences between them are subtle and somewhat variable.

In general, Eurasian is larger, proportionately longer-winged, and has whiter underparts and outer tail feathers, and a whiter trailing edge on the secondaries. Conversely, Oriental averages smaller (a.k.a. Small Skylark) with shorter primaries, buffier underparts and outer tail feathers, and less contrast on the trailing edge of the secondaries.

The songs are similar, although Oriental’s tends to be simpler, typically repeating identical notes or phrases many more times in a row than Eurasian. Many of their call notes are also similar, but Oriental is known to give a sharp buzzy burst in flight that seems to be unknown from Eurasian.

Cf. Woodlark. Eurasian Skylark and Woodlark occur together over much of Europe and western Asia. The two are fairly similar, but Woodlark is smaller, with shorter wings and tail, and usually occurs in woodlands, where it habitually perches on trees. Woodlark also differs in having dark outer tail feathers with white tips, and a bold white bar on the primary coverts—visible in flight on the upperside of the wing.

Cf. Crested and Thekla Larks. Eurasian Skylark overlaps with Crested Lark across a wide band of Eurasia from Portugal to Korea and with Thekla Lark throughout Thekla’s limited Mediterranean range. These species can be very similar, with Thekla roughly intermediate between the others.

Crested Lark differs from the Eurasian Skylark in that it has a taller crest, proportionately longer bill, less distinct markings on the upperparts, rusty outer tail feathers, a rusty tone on the underwings, and no distinct trailing edge on the wings. Thekla Lark can be more nearly identical to some Eurasian Skylarks, except that it has rusty outer tail feathers and no distinct trailing edge on the wings.

Notes

Polytypic species consisting of eleven to thirteen recognized subspecies. Sometimes regarded as comprising three distinct forms, one mostly European, one pan-Asian, and one limited to Japan, Korea, coastal China, southeastern Russia, and nearby islands—although the basis for these subdivisions is not clear as they overlap geographically and do not appear to be readily distinguishable. The prevailing allocation of subspecies is: “European” (arvensis, scotica, guillelmi, sierrae, harterti, cantarella, and armenica); “Asian” (pekinensis, kiborti, dulcivox, and lonnbergi); and “Japanese” (japonica and intermedia).
