24 June Barrow, Morley - a dark bird a dark-brested
bird appeared behind the lab in the parcel area today,
and were seen on two occasions before and after
noon. The 1st time seen they viciously attacked,
striking in flight, three Pomarines that passed
through the lower parcel area, and succeeded
in chasing 2 (but not a 3rd) away. They appear
to be covering a large area but are clearly
interested in the parcel area. Didn't hear any
calls, and saw one brief wing up when the dark
bird landed.
26 June The same (?) two birds seen briefly in this area in the
evening.
27 June Same pair still present; saw a light coloured singer
in the VOTH area.
28 June Saw 2 pairs together over the parcel area, both
of one light and one dark bird. The call is
a "kirow" intermediate in pitch between S. longicaudus
+ pomarines. Neither pair remained in the area very
long.
29 June Saw one behind the lab and one in B. Hou's Area.
30 June One dark bird seen on the Beach Ridge and
another behind the lab.
2 July Two dark phase birds seen over Central Wash along
the Beach Ridge in the morning.
5 July One light phase bird seen near hines IIIA-B in the evening
8 July None light and dark phase birds seen near Farnell bog.
