Woodland structure, rather than tree identity, determines the breeding habitat of Willow Warblers Phylloscopus
trochilus in the northwest of England.
1997: High frequency of extra-pair paternity in a dense and synchronous population of willow warblers Phylloscopus
8% of insects consumed by Phylloscopus
collybita living at Lac Tonga (Noth East of Algeria).
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.

Clustering of territories in the wood warbler Phylloscopus
Some 60 years ago, when researchers first described the small, forest-dwelling warbler called Phylloscopus
trochiloides, they proposed that in Tibet the bird meets the criteria for a ring species.
Amid dog roses, ash trees and flowery fields, blackcaps Sylvia atricapilla, chiffchaffs Phylloscopus
collybita, willow warblers Phylloscopus
trochilus and whitethroats Sylvia communis pour forth their springtime song, children build houses in the trees and dens in the abandoned ammunition bunkers, teenagers ride mountain bikes and grown-ups stroll with their dogs, while water voles Arvicola terrestris amphibius, now scarce in the countryside, busy themselves in the beck.
The ecologically similar habitats of Eurasia and North America may be occupied by different genera of the same family, such as the European thrushes (Turdus, Turdidae) and the North American nightingale thrushes (Catharus, Turdidae), or by unrelated birds that have become morphologically similar as result of living in similar conditions and habitats, as in the case of the Old World warblers, such as Phylloscopus
(family Sylviidae), and the New World wood warblers, such as Dendroica (family Parulidae).
