Encounters of a Sunriver Nature Center Naturalist

Stories of wildlife rehabilitation efforts from our naturalists.

Looks like our Trumpeter Swan, Chuck has a potential mate. This (most likely) female Trumpeter Swan came flying in just a week ago and has made Lake Aspen her surrogate home. The two swans have been spotted by Nature Center paparazzi, spending time together in public.

A pecking order must always be established.
Lets give a “warm” welcome to our two new guests at Lake Aspen, Larry and Sydney; a soon-to-be mating pair of Trumpeter Swans, joining our resident Swan, Chuck. 
For our readers who don’t know, Chuck and Larry are two male Trumpeter Swans who are birth siblings, and native Oregonians. Reunited after a bout for mating rights with Sydney (in which Larry rose champion), the two brothers are now reunited, and are getting along “swimmingly”. Reunited, and it feels so good.
Our lone Trumpeter Swan is going to get some new friends today. Stay tuned for pictures of our new Trumpeter Swans, visiting all the way from our friends at Pronghorn. Looks like the Nature Center is starting its own “bevy” of swans!

Two recent releases of a pair of successfully rehabbed Red-Tailed Hawks by our Lead Naturalist, Kody Osborne. The smaller, male hawk (pictured on top) enjoyed a few words of encouragement from the Naturalist, before being released in our great meadow on the Nature Center grounds. Good luck guys!

Electrocution, a common cause of injury in birds of prey…
This juvenile red-tailed hawk was seen by passers-by as he landed on a telephone pole. After accidentally touching his wing tips to both wires, the bird fell to the ground. The concerned citizen immediately called the Nature Center for help. The hawk was captured and quickly transferred to Jeff Cooney, DVM and Jeanette Bonomo, veterinary technician. Even after several days of veterinary treatment, this beautiful hawk unfortunately did not survive.
Electrocution is a common problem for birds of prey. They prefer to perch on high objects and have large wing spans, making larger birds more prone to these types of accidents. If you observe a bird getting electrocuted or suspect that electrocution has occurred, please report it to the electrical company promptly. They will ask you for the two identification numbers that are visible on the telephone pole. Once the electrical company knows where the problem occurred, bird safe guards will be installed usually within a couple of days.

Here is a Great Horned Owl fledgling received by Jeff Cooney and Jeannette Bonomo from Long Creek, Oregon. After initial rehab and vet care, it was transferred to the Nature Center rehab raptor transition mew. More updates to come.
