To all Tweeters,

We've mentioned some of this work before, but there are always new folks
jumping on board...

We (my grad student, Renee Robinette, and I) are in the midst of a large
study of the "Northwestern Crow," including:

1) behavioral ecology and social interactions ("producing and
scrounging") during beach foraging,

2) development of DNA markers for this population (to be used both for
establishment of kinship relationships in our marked population at
Meadowdale Park in Snohomish Co. and for quantification of geographic
differences, tho' this is not our top priority right now),

and

3) study of the geographic differences in vocalizations (in collaboration
with my dad, Dr. Samuel Ha, a retired researcher and college faculty
member from back East)

We are making active progress in all three areas (see my WWW page at
weber.u.washington.edu/~jcha for papers and scientific presentations): to
respond to the immediate question about vocalizations, we presented data
at a recent Animal Behavior Society meeting that showed very distinct
differences in vocalization characteristics between populations on the UW
campus and in Nanaimo, BC, with intermediate vocalizations recorded at S.
Sequim State Park on the Olympic Peninsula and on San Juan I. We are
currently preparing this work for publication.

If anyone would like more info, or has specific questions, please feel
free to contact me at: jcha at u.washington.edu, or contact my grad student,
Renee at: robinet at u.washington.edu. Also, I'd be happy to present some of
our work (much of it is still in progress!) in an appropriate forum, if
there's interest.

Cheers,
Jim
