Larus Bonaparti Stercorarius Parasiticus habits flights
1876.
(May 17)
Evolutions reminded me strongly of those
of Chastren [illegible] under similar Circumstances,
like them also three individuals would be
seen flying together quite as often as two,
when flying about over the water, the brown
Gullsows very closely excepting in color.
When three or four are fishing on a
school of fry they seem to fairly dance
in the air with delight, sometimes a little
large bird will come along flying mostly
with a very jerky motion but at most
times their flight is very graceful. They
settled on the land flats at low tide in
a large body mixing in with the Sandpipers,
also at times. When sitting there they
are quite shy and will not allow an
approach to within gun range. When
flying about also they are also for
the most part careful to keep out of
shot. On this land flat I saw also
a company of about 20 small square
tailed gulls that I took for H. Bonaparti;
son also during the day fair or at
Stereorarius Parasiticus, they are
called by the summer here sea hens & also
[illegible]
giddy hawks (probably from giddy hawks).
Only flew for the most part in pair.
Their flight was very different from above;
the flapping quicker & firmer and with
circular wheeling like a hawk. We saw
them pick up food from the water
repeatedly & in this they acted like the
other gulls dropping their feet when
about to seize the object. The summer
say that they are tame than the
