A NSWO BAND RECOVERY- A FIRST FOR THE BCCER!

At CSU Chico Reserve's we have banded almost 900 owls since we first opened the monitoring station in 2005. This is the very first time another station has recaptured one of the banded owls from our site. And look at the traveling this little lady did~ approximately 800 miles straight line distance! Of course that probably was not her flight itinerary, maybe making stops in Oregon and Washington? You can see by the banding certificate and map below sent to the "finder" by the Bird Banding Laboratory that we at the BCCER site captured the bird as a Hatch Year (she was hatched in 2017) during fall migration.

Information and points where this female HY bird
was banded (blue, 2017) and recaptured (yellow, 2018)
Then, this October 2018, Rocky Point Bird Observatory in Canada, netted her again during fall migration. It's been a full year since her original band date. Where has she been?  We can only guess between point A and B but I assume she flew north in the winter/spring 2017 to breed, maybe somewhere in Canada. Then she flew south through the tip of Vancouver Island at the RPBO. Here her information was input into the BBL's "report a band site" by Rebecca and she received the certificate of appreciation showing the owl's information.

Foreign Recoveries (a recapture of another stations bird), are much more common where the NSWO banding stations are denser, like back east and Canada. They are valuable to determine timing, direction and distance of migrating owls, and longevity. Check out the map below for active owl stations across the country

2018 NSWO MONITORING OFF TO A GREAT START!

Ken and banders Wyatt and Dawn, plus a great group of veteran and seasoned volunteers will be running the NSWO station at the BCCER again, for the 16th season! We had a training for new assistants to show the banding process, the data we collect, and the value of long term monitoring. Ken and Wyatt conducted their first banding on October 8 and were surprised with an evening of 10 new owls! Eight of the owls were hatched in 2018 (HY) and 2 were second year, SY, hatched in 2017.  It appears that it could be another great year for owl reproduction from this population of owls. If you want to learn about the owls, contact Program Director Ken Sobon, ksobon@thermalito.org.

The owls are curious and often look at you before take off.
