Western Bonelli's Warbler
Phylloscopus bonelli
Western Bonelli's warbler is a small passerine bird, found in forest and woodland. Four to six eggs are laid in a nest on the ground. The eggs are white with reddish-brown markings and are laid in clutches of 3-5 eggs. The incubation period is around 14 days long, and the chicks fledge after 10-14 days. Cuckoo nest predation and brood parasitism are major hazards to the breeding success of western Bonelli's warblers. Like most warblers, western Bonelli's warbler is insectivorous. The adult has a plain grey-green back, green-toned rump and wings and whitish underparts.

Wood Warbler
Phylloscopus sibilatrix
The wood warbler is 11–12.5 cm long, and a typical leaf warbler in appearance, green above and white below with a lemon-yellow breast. It can be distinguished from similar species, like the chiffchaff P. collybita and the willow warbler, P. trochilus by its yellow supercilium, throat and upper breast, pale tertial edges, longer primary projection, and by its shorter but broader tail. It is a summer visitor to the United Kingdom, seen from April until August. It has declined there in recent years. Voice: It has two song types, often (but not always) given alternately; a high-pitched fluid metallic trill of increasing tempo lasting 2–3 seconds, and a series of 3 to 5 descending piping notes of lower pitch piüü-piüü-piüü. The contact call is a soft piping note, similar to the second song type, but shorter and given singly, piü.
