Hi all,

My name is Devin de Zwaan and I am a PhD student at the University of
British Columbia studying an alpine population of Horned Larks in Northern
B.C. We have been colour banding adult larks since 2002 and we have been
using geolocators to track migration since 2015. From the geolocators, we
know that some individuals winter in Washington, Oregon and Idaho.

We are requesting any information on the location of colour banded Horned
Larks. Specifics on where we suspect larks from our population may be
wintering and what information we hope to gather can be found in the PDF at
this link: (

Although we suspect most individuals will be east of the Cascades, some
geolocator data suggests a few individuals winter at least partially in the
Willamette Valley. Essentially, if you know an area near you where larks
are frequently sighted, there is chance a banded lark may be among them!

Any information on the location of banded larks is extremely valuable, as
it will help us substantiate our findings and better understand the
wintering ecology of our population. Last but not least, any volunteers
will of course be credited if we are able to gather enough data!

Please feel free to ask any questions using the email provided on the PDF.
Thank you in advance!
