SPCA (This column was published on March 3, 1997.) The little merganser dove after a minnow and unfortunately followed its prey into the enclosed water intake at the Huntley Power Plant on the Niagara River. Now it swam desperately to avoid being sucked by the swift current against a screen where it would suffocate. Trapped, its chance of survival was essentially nil. Ted Janese found it there when he made his last inspection of the area late one afternoon. He and his Niagara-Mohawk co-workers Fran Gunning, Bill Stratman and Mike Galas, stayed on after their shift ended to extricate the valiant bird but, try as they might, they couldn't free it. End of story? Not quite. Concerned about the ill-fated merganser, Janese went in early the next morning to check the intake area. To his surprise he found the duck, near exhaustion but still struggling pitifully to stay away from the metal grate. Alerted by phone, Gunning brought in a large minnow net. With it the men were able to rescue the fatigued bird. A male red-breasted merganser is one of our most attractive ducks. It is the same size and has a green head like a mallard but it would never be mistaken for that species. A slimmer bird, it has a thin, serrated bill, which gives mergansers their alternate name -- sawbills. This one gobbled the dozens of minnows the men provided until its crop bulged and a fishtail hung from its mouth. A call to the S.P.C.A. brought wildlife rehabilitation program administrator Diane Obusek to care for the merganser. She examined it, treated the leg that had abrasions from rubbing against the cement wall of the intake, continued to feed it and finally released the anxious duck back into the Niagara River. I didn't see the happy conclusion to that story, but I joined Ms. Obusek and Jeff Everett at the foot of Sheridan Drive to watch them release a rehabilitated great blue heron. The disoriented bird had been dug from the snow on a suburban rooftop and cared for until it was now ready to return to the wild. Unceremoniously tossed into the air, the feisty heron quickly recovered its aplomb and flew slowly out over the river. Through binoculars I watched it join companions on Strawberry Island. I wonder if they would believe the newcomer's story. This was my first interaction with the Erie County Society for the Prevention of Cruelty to Animals and I took the opportunity to rejoin the two rehabilitators at the Ensminger Road S.P.C.A. headquarters. Clearly this was homework I should have done long ago. It's difficult to express strongly enough my favorable reaction to this remarkable organization that is entirely supported through public contributions. Like many others, I thought of it simply as a place where you adopt a pet dog or cat. It certainly plays that role, but the building is also a state-of-the-art facility for injured animals including wildlife. Last year alone, for example, over 1600 wild animals were treated. Senior Veterinary Technician John Lattimer, who started the wildlife section six years ago, showed me the operating room where veterinarians like Dr. Michael Bonda perform surgical procedures. It rivals similar facilities for humans. But the news is not all good. Ms. Obusek showed me their kestrel, screech- owl, red-tailed hawk and bald eagle, each with injuries from which it will not recover. The eagle is one of three shot in the region this winter. Such birds and animals "repay" the Society for their care by appearing in educational programs. We should be proud of this excellent facility, its fine staff, its many volunteers and contributors and the services they provide.
