JP3 was found dead on April 16 2001 and died probably early April of the same year. The strong head and bill suggest a male; maybe autopsy will bring certainty.
The wing pattern left and right is not exactly the same: left p9 shows a small but distinct white mirror, right p9 lacks this mirror.
On both wings, a sub-terminal band is visible on p5-p10 on both wings and p4 shows black markings which do not fully connect outer and inner-web at the shaft.
From beneath, the typical LBBG pattern of the primaries is visible: P10 is almost all black, all the way from the base, p9-p5 show indistinct dark grey 'tongues', but never as obvious and sharply demarcated as in e.g. cachinnans. Between the black sub-terminal band and the grey patch of the primaries, no white crescent is visible, though on the under-wing, a hint of what may be such a crescent is visible at p5 & p6.
As can be seen in the left wing, this LBBG was moulting the outermost greater coverts, which are a few inches shorter than the more inward feathers. In the right wing, this moult appears as a gap between greater coverts and the primary covert row.

JP3 was ringed July 4th 1993, near ECT container terminal and died just a couple of hundreds meters from that place and was in 9cy.
