Re: [cobirds] length of Varied Thrush winter stays

Hi Dave,

The Colorado Bird Records Committee has 48 records for Varied Thrush dating back to 1972.  The longest stay is of one at Beulah, Pueblo County, that stayed from December 13, 1986 to February 21, 1987.  A duration of 70 days.  Looks like the Fort Collins bird may have exceeded that record.  Typically, Varied Thrushes haven't been documented staying for more than a few days, although there are plenty of exceptions that make me wonder if some birds move around locally (but are not refound and therefore recorded for just a couple days) while others reliably stay in one location during their winter visit and thus are seen for weeks.  I have provided the list of records and dates below.  Of course, the CBRC would appreciate further documentation for any of these that would extend the range of dates of occurrence.

good birding,

Doug Faulkner

The landowner in Fort Collins (Ken Allen) who has a Varied Thrush coming to his backyard asked a good question.  What is the longest stay documented for a Varied Thrush in a local area in Colorado?  His male has been present for around 11 weeks (since mid-January).  I would appreciate hearing from anyone who has the beginning and end of a winter stay recorded for other Varied Thrush individuals in the past.  Thank you.

By the way, Ken is still OK with folks coming by to see the Varied Thrush if you call first (907/225-0988 home).  His address is 1719 Ticonderoga Drive in Fort Collins.
