It is also habitat to some European migrants like the Wood Warbler (Phylloscopus
sibilatrix) and the Barn Swallow (Hirundo rustica).
The samples were collected from the following species of birds: Taiga Bean Goose (Anser fabalis johanseni), Siberian Thrush (Geokichla sibirica), Song Thrush (Turdus philomelos), Fieldfare (Turdus pilaris), Redwing (Turdus iliacus), Black-Throated Thrush (Turdus atrogularis), Common Tern (Sterna hirundo), Green Sandpiper (Tringa ochropus), Common Greenshank (Tringa nebularia), Red-Throated Flycatcher (Ficedula albicilla), Temminck's Stint (Calidris temminckii), and Dusky Warbler (Phylloscopus
Woodland structure, rather than tree identity, determines the breeding habitat of Willow Warblers Phylloscopus
trochilus in the northwest of England.

Evidence of reduced habitat quality for Willow Warblers (Phylloscopus
trochilus) breeding close to a highway.
Up to 6.4% of the species observed had no breeding opportunities within the study area (Actitis hypoleucos, Aquila pomarina, Merops apiaster, Muscicapa striata, Phylloscopus
trochilus, and Sylvia borin).
These studies produced an outpouring of publications in several scientific journals, largely on social factors influencing breeding behaviour in insects and seabirds, but also on insect migration in the Pyrenees and behaviour of the western sandpiper Ereunetes mauri and the willow warbler Phylloscopus
trochilus in continuous daylight.

collybita) did not seem to be directly affected by the circulation conditions.
