Nyctea scandiaca
10.
27 June Barrow, Alaska
After I arrival + checked the nest, I
sat in the blind for 1½ hours. During
this time, The 4 were very cautious
+ came to the nest about 6 times.
Each time she was frightened
away either by movement in the blind
or jaegers nearby. When she was away
from the nest, she would sit on
the flat lands below the nest where
she was continually attracted
my jaisan. Its reaction to the
dove bombing was to jump with air + apparently try to get her talons
up in the direction of the intruders.
In the process of doing this, she
would jump about 2-4 feet
in the air, bring her feet up, where
at the same time, the body would
flip (like someone attempting to do
a somersault - but not quite making
the flip). The 8th one then sat
calmly along the ridge about 10
yards away. When I first approached
the nest, he attempted to do a
disrupting display by flapping his
wings wildly and making a low
grunting call.
