1020 - standing beside stake 9 for 1.5 min. when suddenly 8 dunlin flushed within 5 ft
of me, began giving distraction display. 4 eggs in nest, which is lined w/lichen + grasses,
in a clump of sedge surrounded by hummocks of moss.

followed 2 RB's today see journal, following acutts. saw dis-
playing RB (illegible) beginning secondary molt.
Grid 3, 8 km S. of NAPL by road, Pt. Barrow, Alaska
8 July
first dunlin nests that I had between the last Grid 3 census area (2 July) and today Schannel
said he had detected it yesterday. Both RB1 and RB2 have hatched. Behavior of
adults in/on contrasts w/ that of incubating birds. First-flue are an inordinate # of
trios - probably because when one pair gets upset and begins calling a neighbor (flown)
to find out what's up - without being supplanted. It seems appears that the birds will leave
chicks and fly toward gun calling at a much greater distance than that at which they
would leave the nest. very excited calling, am sharp alarm note given repeatedly. If you
continue on forward when they flew in from (presumably near to chicks) they get even more
excited - so much so that they appear to be running in place, jumping rapidly from one
foot to the other while calling

first dunlins fledged
Grid 2
30 July
I am detecting a curious association - dunlin appear on my census areas w/ Nivivella dominica
and it appears as if they move with them as well. today in the lower portion of Grid 2 I picked up
a flock of dunlin foraging in the high polygon area, running both in the troughs but more frequently
along the crests. adults and juveniles present, the adults not acting broadly (or protectively). With them
were several Nivivella (see grid data sheet). During the cursors I flushed them, the whole
group moved off together - flying to another, similar area of the grid - this now) not
suggest an association in itself - but recently I've been coming across these two species together
more often than I have been encountering them separately.
