The red wing tag appears to be one of the cattle tags they've been using in
Idaho, at Lake Walcott on the Minidoka National Wildlife Refuge. Here's some
information I found courtesy of Google.

REPORT PELICANS WITH LEG BANDS AND WING TAGS

In addition to the 600 pelicans marked this year, Fish and Game will
continue to band and tag hundreds of young pelicans from both of Idaho's
nesting colonies over the next 2-3 years. The birds from Blackfoot
Reservoir colony will continue receiving black wing tags and those from Lake
Walcott will receive red wing tags. Both colors of tags will have white
unique three digit codes and all tags are on the right wing near the "elbow".
It will be helpful to the project to receive reports of marked birds from
the public.



If you see one of the marked birds, please contact the Pocatello Fish
and Game office at (208) 232-4703, the Jerome office at (208) 324-4359, or
Colleen Moulton in Boise at (208) 287 - 2751. You may also send an e-mail
to mwackenhut at idfg.idaho.gov. jbarrett at idfg.idaho.gov, or
cmoulton at idfg.idaho.gov. Please report the date the tagged bird was seen,
the location, tag color, and the number if possible.
