Pallid swift / Fahlsegler (Apus pallidus)

Wikipedia: Pallid swift Source: OTHER Apus_pallidus_-Greece-8.jpg
Classification: Genus Apus; Subfamily Apodinae; Family Swifts (Apodidae)
General: The pallid swift (Apus pallidus) is a small bird, superficially similar to a barn swallow or house martin. It is, however, completely unrelated to those passerine species, since the swifts are in the order Apodiformes. The resemblances between the groups are due to convergent evolution reflecting similar life styles. [more]
Vocalization: Similar to Common Swift, but usually very helpful for ID. Almost di-syllabic, with marked accent on second syllable which rapidly drops in pitch, "srrrree-aah". [Link]
Calls: Common swift has a more even call, with accents on first part, without the sudden pitch-drop. [Link]
Physical details: length=16-17 cm, wingspan=42-46 cm, weight=41 g
