This pictures shows the black, slender bill; long sloping forehead; long lores and black eye. Slight streaking on the nape and a bulging chest. The long black primaries also are easily visible at this angle. Also the brown coverts and dark centred tertials with white tips are noticable.
This pic emphasises the very long primary projection; white tips to the tertials and an all white head. The primary projection shows the length of the tail tip to the primary tip is greater than the tertial tip to the tail tip.
The white rump with a strong black band on the tail is clearly seen here. The pink legs are just visible, which when clearly seen were very thin and long.
