White-winged Tern (Chlidonias leucopterus)
Woodchat Shrike (Lanius senator)
Breeding adult easily identified by white tail/rump combined with jet black under wing coverts and silvery upper wing. Immature with brownish back contrasting with pale, silvery upper wings and pale rump. Broad white collar, and lacks dark breast patch of immature Black Tern. Adult winter most liable to confusion with other terns, but upperparts much paler than Black Tern. Contrasting dark outer primaries and secondaries to rest of wing. Often retains some black under coverts even in winter which is diagnostic if seen. Slightly more compact than Black Tern and often recalls Little gull in shape. Bill noticeably shorter and thinner than in Whiskered Tern.
Sound:Mostly silent away from breeding ground. Most diagnostic call a dry, rolling "krrrrrr-ta-ta" where the rolling is followed by one or two accentuated syllables, or just simply "krrrrrr". Used in excitement.

Adults easily recognized by rufous cap, black back, white scapular patches and white rump. Appears more compact and bigger headed than Red-backed and Lesser Grey Shrike. White spot at base of bill larger in female than in male. Immatures told from Red-backed Shrike by whitish scapulars, greyer upperparts, diffuse patch at base of primaries, pale rump and dark brown tail. Young birds may also be confused with Masked shrike, but note less contrasting primary patch, darker forehead, browner upperparts and wings, pale rump, shorter tail and deeper bill. Subspecies L. s. badius lacks primary patch. More skulking than many shrikes. Likes high viewpoints.
Sound:Alarm call a dry, magpie-like "che-che-che-che-che", or a nasal, ascending oriole-like "weea". Territorial song loud and varied. Often repeats phrases and includes mimicry. Alternativ song a more continuous chattering with impressive mimicry similar to Red-backed and Lesser Grey Shrike, and difficult to separate from those.
