Calcanius lapponius (1)
June 3
Away from the buildings, out on the newly exposed
patches of tundra I saw my first hayland longspurs.
Brightly colored birds with yellow beaks and much chestnut.
Most birds seemed to be paired, although there were some
single males. Some males went thru the flight display.
June 4.
One more day of thawing has doubled the exposed
patches of tundra and there were clearly more longspurs
around today.
June 5.
Observed one pair of birds - B a q, feeding on an exposed
land. They seek food of the ground like most seed eating
birds but these two birds also hacked freely - to the
ground and they flicked their heads side ways so that
small pieces of dirt were flying left and right.
June 6.
Longspurs were actively engaged in chasing today.
I noted two males, one of which was an intruder being
persued for a full 4 minutes. Wherever this stranger landed
the owner of the territory would move closer in a sneaky
crouched manner with be launched back. When their
wild flight they hoped to enter a third territory, the owner
of this territory joined the chase.
7 June
Found a partially completed nests. The female struck close
to the area; flying around me. She was perfectly silent all the
time (Nest on Beach Bridge).
9 June.
Found one nest, partially lined with small feathers. The birds
kept nearby and acted excited. On the Honey Bucket side of the
road I found an other nest which appeared completed, but no
eggs yet. Also, the owners of the nest were not around. Again.
