Hi,
Paul Opler sent me the following message and asked me to share it with COBIRDS:
[For the last four days at least there has been an increasingly
large number of gulls roosting for the night on the south end of Boyd
Lake, then spending the day feeding in weedy alfalfa fields just south
of Mountain View High School, just south of intersection of US 34 and
Larimer Co. Rd. 9 [=Boyd Lake Avenue]. I observed these beginning on the
afternoon of the 13th at about a thousand birds until this morning the
16th there must be at least several thousand individuals, possibly many
more. These are mainly ring-billed gulls, but there I included are some
California gulls and 3-4 Lesser Black-backed gulls. I scanned as many of
the birds as I could and there were none of the larger pink-footed
Herring or Thayer's Gulls included. The birds are very active and vocal
and can be heard calling at night from Boyd Lake -- we live just across
the street. I have heard this frenzy around this time of year in the
past but didn't know where they hung out during the day.
