觀察細節

Observation and media provided by Jem Babbington. All evidence so far points to Delicate (P. l. irakensis) in the Aramco camp in Dhahran. One image shows distinct barring on the upper side of the tail, which is long and narrow and held rather straight (i.e. not as fanned as Graceful). Another image shows faint narrow subterminal bands on the under side of the tail, not the darker, rounder, more heart-shaped bands found on Graceful. The song registers at 4 to 4.5 phrases per second, which is faster than the average rate sung by Graceful in the Al Ahsa region.
