Affected person of the Week: Brandt’s Cormorant
Radiograph from October 6 present the fishing hook lodged in Brandt’s Cormorant abdomen.
A Brandt’s Cormorant got here to us final week after ingesting a fish hook and having two others lodged in its mouth. The 2 in its mouth had been eliminated by our colleagues at Native Animal Rescue in Santa Cruz, however the hook that had been swallowed was a possible significant issue which will have wanted surgical procedure; therefore, the chook was transferred to us for additional care.
A way referred to as “cotton-balling” helped the chook to regurgitate a fishing hook from its abdomen.
On radiographs, the hook seemed to be situated within the chook’s ventriculus (the second of a chook’s stomachs), but it surely was not clearly hooked by means of the abdomen wall. As a result of the hook seemed to be free floating contained in the abdomen, and surgical procedure is all the time a critical endeavor that we attempt to keep away from each time attainable, we used a low-tech method to encourage the chook to regurgitate the hook. This technique lets us keep away from invasive surgical procedure on a large proportion of birds that ingest hooks. We name this therapy “cotton-balling”…though we don’t use precise cotton balls.
Cotton-balling is once we stuff thick wads of cotton solid padding inside a number of fish and pressure feed the fish to the chook. The cotton will increase the quantity of indigestible materials within the chook’s abdomen and turns into entangled with the hook within the chook’s abdomen. If all goes as deliberate, the chook regurgitates the indigestible cotton, and the hook comes out with it! We cotton-balled the cormorant on Wednesday, however no hook appeared. We cotton-balled once more on Thursday, however nonetheless no hook regurgitated. Nevertheless, on Friday, we had been rewarded with the hook discovered on the underside of the aviary! This technique doesn’t all the time work, however fortunately it did work this time. No surgical procedure wanted!
The chook stays in care receiving therapy for the injuries in its mouth, and is slowly gaining weight and recovering from fairly extreme emaciation and anemia.
You may see the chook’s radiographs from October 6, and the hook after being regurgitated (and cleaned) on October 9. The chook has a metallic federal band on its leg which is seen within the radiograph as a strong white form round its leg. An added bonus: we realized the chook was banded on the Farallon Islands Nationwide Wildlife Refuge as a chick two years in the past!
