<DIV class=Section1>REQUEST FOR SHORT-EARED OWL FEATHERS: We are investigating
Short-eared Owl movement patterns in North America and are asking for feathers
for stable isotope analysis from anyone who may be conducting Short-eared Owl
research, or who may experience incidental encounters through banding or road
kills. Based on inspection of museum specimens and consultation of several North
American and European references, it appears that P1 is the first feather
molted, and therefore would have the highest probability of recording the
isotopic signature of the summer location. Thus, a small sample of vane tissue
(i.e., 1-2 cm2) from the lagging, proximal edge of P1 would be ideal, so as to
limit impacts on flight. If a molt limit is obvious, samples from all apparent
generations would be valuable, as would photo documentation, as this may allow
for the determination of up to three previous summer locations. Samples from
juveniles are particularly valuable to verify the Short-eared Owl isotopic
signature against existing maps, and while P1 is again preferable, the age of
the owl may dictate that a contour feather be collected instead. If you are
interested in providing feather samples for this study, please contact KRISTEN
