Ringed July 03 1997. In this bird most of the primary tips (which haven't
been very large after all) have been worn away. The tertials, inner
wing-coverts and scapulars are worn as well. There are no moult gaps
visible in either one of the feather tracts, but as can be seen in the top
picture, the inner median covert and two groups in the central median
coverts were moulted more recently than the brown hued other medians. The
group of greater coverts show a similar moult strategy, with the inner
greaters moulted last and those feathers are still plain grey, contrasting
with the central and outer greaters. |
