Adult
6003175 was very territorial on May 13 2002, probably defending a nesting
place along the Amazonehaven - Missouriweg. This large colony is part of a
future industrial complex and this year, summer 2002, first construction
works were executed on May 22. The soil had to be prepared, destroying
over 500 nests, probably over 1,000 eggs of Lesser Black-backed Gulls. In
the nect weeks many adults left this colony, including many ringed
individuals which can be found in the Adult April and
Adult May
sections. For a whole month, 6003175 wasn't seen, but finally, July 4
2002, it was seen again, close to the place where it was seen last in May.
It proved to be paired again but a nest wasn't found.

The
primary tips are slightly worn. P9 has a round mirror just reaching the
feather's edge, p10 has a large mirror, reaching the inner and outer-web over
the entire length. The sub-terminal band on p10 is broken in the centre. The
lower tertials look relatively fresh while in the upper tertials the white tips
are almost completely worn away. A few greater coverts start to develop a brown
hue, but the 5th and the few central greater coverts look fresher and are plain
grey. The mix of brown hued older feathers and relatively new plain grey
feathers can be found in the scapulars as well.
