Its breeding habitat is quite specific, and even near relatives do not share it; for example, the willow warbler (P. trochilus) prefers younger trees, while the wood warbler (P. sibilatrix) prefers less undergrowth.
440 BC) described the crocodile in detail, though much of his description is fanciful; he claimed that it would lie with its mouth open to permit a "trochilus" bird (possibly an Egyptian plover) to enter and remove any leeches it found.
There were territories of at least four pied flycatchers (Ficedula hypoleuca), three willow warblers (Phylloscopus trochilus), three bramblings (Fringilla montifringilla), one great tit (Parus major) and one Siberian tit (Parus cinctus).
We studied the orientation of juvenile individuals of three small, passerines – blackcap Sylvia atricapilla, garden warbler and willow warbler Phylloscopus trochilus weighing from around 10 g in the willow warbler to around 20 g in blackcap and garden warbler.
In support of this hypothesis, recent divergence with extensive morphological variation has, for example, been documented in several bird species; redpolls (Carduelis flammea; [10]; but see [47]), yellow wagtails (Motacilla flava; [11]), yellow-rumped warblers (Dendroica coronata; [12]), willow warblers (Phylloscopus trochilus; [48]) and dark-eyed juncos (Junco hyemalis; [13]).
However, a larva of Dermacentor sp. was recovered on a northward-migrating willow warbler (Phylloscopus trochilus) in Akeröya in 2005 [ 6].
The Lithuanian samples belong to the northern subspecies (acredula), but are as willow warblers in southern Sweden (trochilus), homozygous for the southern allele of AFLP-ww1 [ 15].
Here we used 454 sequencing of brain-derived transcriptomes from two differentially migrating subspecies of the willow warbler Phylloscopus trochilus to detect genes potentially underlying traits associated with migration.
In this study, we simulated first-fall migration of the most numerous trans-Saharan avian migrant, the Willow Warbler (P. trochilus), along the SW European migration corridor(Hedenström and Pettersson 1987; Hahn et al. 2009).
To do so, we developed an individual-based model (IBM) to simulate full drift and partial compensation migration of juvenile Willow Warblers (Phylloscopus trochilus) along the southwesterly (SW) European migration corridor to the Iberian coast.
In this study we attempt to identify genes potentially associated with migratory traits by using next-generation sequencing of a brain-derived transcriptome from two subspecies of a small passerine, the willow warbler Phylloscopus trochilus.
