Leaf warblers (Phylloscopidae)

Family (Latin)
Phylloscopidae

The Phylloscopidae comprises many small tree-loving warbler species. Many are canopy or sub-canopy dwellers, gleaning insects from leaves or catching food on the wing.

Phylloscopus ibericus
Phylloscopus inornatus
Phylloscopus canariensis
Phylloscopus trochilus

Very similar to the chiffchaff, the two species are distinguished by their song. 

Phylloscopus collybita

The chiffchaff is a common and widespread leaf warbler which breeds in open woodlands throughout northern and temperate Europe and Asia.
