 University of California, San Diego: External Relations: News & Information: News Releases : Science
In the case of the greenish warbler, Phylloscopus trochiloides, the scientists discovered a continuous ring of populations with gradually changing behavioral and genetic characteristics encircling the Tibetan Plateau, which is treeless and uninhabitable.
At each end of the ring of interbreeding populations, which extend around each side of the Tibetan plateau and through the Himalayas, the scientists found that the two distinct, non-interbreeding forms of the bird do not recognize each other’s songs, which are critical in the selection of their mates.
"The greenish warbler is the first case in which we can see all the steps that occurred in the behavioral divergence of two species from their common ancestor.

The Arctic Warbler, Phylloscopus borealis, is a widespread leaf warbler in birch or mixed birch forest near water throughout its breeding range in Fennoscandia and northern Asia.
This warbler is strongly migratory and the entire population winters in southeast Asia.
Its single wing bar distinguishes from most similar species, except Greenish Warbler, Phylloscopus trochiloides.

 Greenish warblers   (Site not responding. Last check: 2007-11-07)
Male greenish warblers are very active singers, using song both to attract females and to defend their territories.
A male greenish warbler will aggressively respond to songs that it recognizes as belonging to its own species, intending to chase an intruding male out of its territory, but it usually will not respond to song from a distantly related population.
All of these patterns are consistent with the hypothesis, first proposed by Ticehurst (1938), that greenish warblers were once confined to the southern portion of their range and then expanded northward along two pathways, evolving differences as they moved north.

Leaf Warblers are very small insectivorous birds belonging to the genus Phylloscopus of the Old World warbler family Sylviidae.
These are active, constantly moving, warblers always associated with trees, though normally in fairly open woodland rather than tight plantations.
Compared to some other warbler families, their songs are very simple.

 "Ring Species: Unusual Demonstrations of Speciation" by Darren E. Irwin, Ph.D.
Greenish warblers, a ring species, are found in parts of Asia and eastern Europe.
In Siberia, two distinct forms of greenish warblers coexist, one in the west and one in the east, their distributions narrowly overlapping in central Siberia, where they do not interbreed.
Large areas of greenish warbler habitat are being deforested, particularly in China, India, and Nepal, and this process might continue to the point that future biologists would not be able to recognize greenish warblers as a ring species.

HABITS.—Our experience both in 1926 and in 1932 leads us to believe that the orange-crowned warbler which Wright saw in a spruce wood on Savage River on May 21, 1926, at 2,800 feet altitude, was merely a late migrant passing through the McKinley region to its breeding ground farther north in the Yukon Valley.
The breeding female is quite unlike her mate; she is greenish in coloration on the head and back with yellowish under parts.
The greenish female is highly streaked with fl on the sides of the throat and the flanks.

The new data comes from the songs of the greenish warbler, a bird that lives in the foothills of the Himalayas.

 OSME - Green Warbler in Saudi Arabia
However, it lacked white fringes and tips to the tertials, and dark centres to the wing-coverts, and the bill was rather large and not all dark.
Arctic Warbler P. borealis can also have two wingbars, but the Saudi bird's diminutive (not comparatively bulky) appearance, short bill, supercilia meeting above the bill, dark legs and bright green upperparts are inconsistent with borealis (Bradshaw and Riddington 1997).
Because of the pronounced greater covert wingbar, distinct upper wingbar, and yellowish tinged head- and neck-sides it was most likely Two-barred Greenish Warbler P. plumbeitarsus or Green Warbler P. nitidus (Baker 1997), both of which are variably treated as conspecific with, or specifically distinct from, P. trochiloides (see, e.g.

 Dutch Birding - Greenish Warbler breeding on Schiermonnikoog in May-July 2003
In May-July 2003, a pair of Greenish Warblers [Phylloscopus trochiloides] raised three young on Schiermonnikoog, Friesland, the Netherlands, in the Wadden Sea off the north-east coast.
In the evening of 29 July (the first day of the autumn's ringing season on the island), a first-year Greenish Warbler was trapped and ringed at Groene Glop, c 1200 m east of the breeding site.
This bird still showed some downy feathers on the underparts and is likely to have been one of the young raised in the village.

We're not sure if the warbler was having an identify crisis--after all, he was similar in color to the goldfinches--or if he had just developed a hankering for oilseed.
We should mention that there's a great deal of plumage variation in both American Goldfinches and Pine Warblers; the warbler we caught this week was particularly bright, but we have captured individuals that were nearly gray.
On rare occasions we see a Palm Warbler, Orange-crowned Warbler, or Common Yellowthroat after mid-October, but of the 34 warbler species we've banded locally, most are pretty much warm weather junkies that migrate through on their way to Mexico, Central America, or even South America.

Several Phylloscopus warblers besides P. borealis are potential candidates for Australia such as Greenish Warbler P. trochiloides and Eastern Crowned Leaf Warbler.
In summary the committee noted that the observers were very competent and experienced and that it is highly likely that this record does reflect a sighting of an Arctic Warbler.

Part of the difficulty in proving the theory has been that few examples of such species are known today.

Two distinct forms of greenish warblers co-exist in central Siberia but do not interbreed there, making them distinct species in that region.
