Lesser Grey Shrike (Lanius minor)
Sandwich Tern (Thalasseus sandvicensis)
In all plumages told from Great Grey Shrike L. excubitor by very long primary projection, stout bill, large rectangular wing patch and extended white at base of tail. Tertials without white edge. Adult birds with black forehead (more extended in male and often speckled grey in female), and a pink wash to underparts (especially male). Immatures lack the black forehead and wing coverts have pale fringes.
Sound:Contact call a series of Magpie-like "che-che-che". Two very different types of territorial song: Most diagnostic is the short song which consists of a single, parakeet-like "irtscha". Like in a sneeze, with rapidly rising and falling pitch. Given monosyllabic, disyllabic or in series. Other song type very varied with lots of mimicry of other birds and mammals. Similar to Woodchat Shrike but usually also includes the call from the short song. The varied song is more subdued in mated males.

CCLarge tern with black bill, with yellow tip (adults). Bill all black in juveniles. Long black cap and shaggy crest. Generally leaves a much whiter impression than other terns in the region (except Roseate Tern). Adult summer: Yellow bill-tip. Tail pure white, and upperparts pale grey. Outer primaries darker than rest of wing, and contrast increases in worn plumage. Broad white trailing edge to inner wing. Underside of primaries with faint narrow dark trailing edge. Forehead white in adult winter and first winter plumage. Juveniles: scaly upperparts and dark bill. Less evenly coloured than juvenile Gull-billed Tern. First winter birds similar to juveniles, but back purer grey and bill shorter. Can be mistaken for Gull-billed Tern, but note different profile. Flight powerful with evenly narrow wings and a front-heavy appearance, due to the long head and bill. Often dives from high above the surface and stays under water longer than Common and Arctic T.
Sound:Contact call a sharp and grating "keeree-eek". Often compared to the pressing of amalgam into a tooth.
