Birding in the Atchafalaya Basin

Norbert and his lucky crew of six, about to set off on our boat tour.

The National Wildlife Rehabilitators Association (NWRA) 2012 Symposium was every bit as gratifying as I had hoped. The first day, Tuesday, was a long one however. I had to leave my house at 4:30 am to catch a 7 am flight to Baton Rouge, LA via Charlotte, NC. My friend and fellow rehabber, Roxy Brandenburg, was on the same flight, and we were both excited to be arriving in time for a tour of Cypress Island Swamp. The Nature Conservancy manages Cypress Island Preserve; 9500 acres of cypress and tupelo trees dripping with Spanish moss, and bottomland hardwood forests at Lake Martin. The preserve is part of the Atchafalaya Basin; America’s largest river basin swamp.

Atchafalaya Basin branches off the Mississippi River and extends 135 miles to Atchafalaya Bay, where it eventually empties into the Gulf of Mexico. You may remember hearing about it last spring, when the Mississippi River was flooding its banks and there was talk of opening up the floodgates into Atchafalaya Basin to save many homes and towns from the floodwaters. The growing delta of the Atchafalaya River is the destination of thousands of water birds that migrate along the Mississippi Flyway. More than 300 species overwinter in the diverse habitats it offers, and hundreds more use these habitats to sustain them on their migration to points further south in Mexico and South America.

Roxy and I arrived in Baton Rouge in time to dump our bags at the hotel and grab a quick lunch (our first taste of the incredible Cajun cuisine that was to be another highlight of the NWRA Symposium) before catching the tour shuttle. Unfortunately the early morning flight caught up with me. I fell asleep on the bus and missed most of the scenery en route to the swamp. I awoke as we passed through a quaint little town called Breaux Bridge, which proclaims itself the “Crawfish Capitol of the World,” and is full of history and local culture including antique shops, beautiful architecture, restaurants, and live music. I wish I could have stayed and visited, but from there it was a only a short drive to the Cyprus Island Swamp. http://tourism.breauxbridgelive.com/index.php?option=com_content&task=view&id=12&Itemid=43

Our first stop was The Nature Conservancy’s Cypress Island Visitor’s Center, where we disembarked for a quick bathroom break. Most of us, eager to go back to where we had just passed hundreds of Great Egrets in the trees and on nests, got right back on the bus to proceed, but I later learned that one person was rewarded for her dallying. She walked down to the water’s edge where she disturbed a black snake napping on the shore. When she got out her camera to take a picture, the snake opened its jaws to reveal an enormous “cotton” mouth. She had inadvertently disturbed a Water Moccasin, and had snapped a great photo of its signature mouth!

Back at the rookery, a Audubon Society volunteer had kindly set up about 8 spotting scopes in a row, each one focused on a fascinating sight in the swamp, including an Alligator, a Snapping Turtle, a Brown Water Snake in shed, a Great Egret displaying his incredible plumage to the females, a Little Blue Heron, a Roseate Spoonbill, an Anhinga, and a Crested Cormorant. The birds he had focused on were among hundreds that had already arrived and begun the ritual of courtship and nesting. He told us that, in the next month, these hundreds will become thousands, and more species, including Cattle and Snowy Egrets, White Ibis, Little Green and Great Blue Herons, and Black-crowned and Yellow-crowned Night Herons will arrive, and the young will be hatching and visible in the nests. What a sight that will be! http://www.nature.org/ourinitiatives/regions/northamerica/unitedstates/louisiana/placesweprotect/cypress-island.xml

From there we drove a short piece down the road to the docks and broke into smaller groups for our boat tour. I managed to place myself in the smallest boat, a group of six, and we followed Norbert, our 76 year-old native “swamper” guide, to board. My pictures tell the rest of the story. We saw many of the above-named birds in hunting mode, and alligators and turtles galore. The sun had just emerged following a day of record rains (up to 15 inches!) and the reptiles were out basking. The alligators ranged in size from about 8 feet to 14 feet, and Norbert explained that the age difference was roughly 100 years! An 8-footer being 50 years old, while a 14-footer is 150.

Midway through the tour, Norbert parked the boat in some floating water hyacinth (an extremely invasive non-native plant that requires intense management to keep waterways open), and showed us the minute flowers of Spanish Moss, and how they pollinate by wind. In our nearby surroundings, we saw a 6-foot alligator, a “chameleon” Green Anole Lizard change color, and another Brown Water Snake.

Norbert then got out some tattered clippings of a National Geographic article that showed him as a younger man in the swamp. He had grown up in the swamp, and raised his own kids on a diet of wild swamp critters, including alligators, turtles, beaver, and raccoon.  Last but not least, Norbert pulled out a jug of his very own Moonshine, and poured each of us a shot! It was surprisingly good!

Finally, Norbert took us to where a few spectacular trees, less desirable as timber due to their prolific branches, grew to the ripe old age of 1500 years!  He explained that Cypress is extremely slow growing due to its wet growing conditions, so while these trees have an enormous girth of 10+ feet, they are deceptively old for their size. We also saw the Cypress “knees”, an emergent part of the roots that allow the trees to breathe air, and Norbert explained how the knees are desirable for creating elaborate carvings, and so most had been cut. Somehow the trees had managed to live on. That concluded our wonderful boat tour, and we returned to the docks to board our bus for the ride back to the hotel.

The next day, Wednesday, the NWRA Symposium kicked off with an awesome keynote speech and slide presentation given by C.C. Lockwood, a free-lance photographer who spent the better part of the last thirty years living in the Atchafalaya Basin and photographing its unique flora and fauna. He has written several incredible books and produced an award-winning film on the Basin, published by National Geographic.  It turns out that it was C.C. Lockwood who had photographed Norbert as a young man, in the old tattered National Geographic clippings he so proudly shared with us. C.C. Lockwood’s latest honor is that one of his photographs; of Cypress trees set against a beautiful sky reflected in the water, was selected for the US Postage Stamp celebrating the 200th Anniversary of Louisiana Statehood.  It will soon be available at your local post office.

These were two highlights of the Symposium for me, but it was only the beginning of a week of superb presentations and informative discussion about a wide range of important topics relating to wildlife rehabilitation ranging from Care of Opossum Neonates and Rehabilitating Sea Turtles to acquiring fish and insects for feeding wildlife, and Getting the Most out of Eagle Scout Projects. Some of my favorite presentations were Physical Therapy in Aquatic Birds (easily translated for use in raptors), Treatment of Lead Intoxication in Bald Eagles (over 85% of all the Bald Eagle patients received at The University of Minnesota Raptor Center have at least some lead in their blood, and most have clinical signs of lead poisoning), Strigiformes – Why Owls Aren’t Just Raptors by Another Name, Infectious Diseases of Raptors, Reuniting and Fostering Raptors, Triaging Injured Wildlife, and Beyond the Individual – Rehabilitation of Species, a thought-provoking presentation and discussion about the difficult choices required to save a species.

I’m sure that, as 2012 unfolds, you will hear more about my experiences and education at the 2012 NWRA Symposium. Meanwhile, I have returned to Maryland and Owl Moon where I am enthused and invigorated to get back to the work of rehabilitating raptors!

Week of the Red-Shouldered Hawks: March 12, 2012

On February 26 I was enjoying an unusually leisurely Sunday when I received a call from Officer Douglas of Frederick County Animal Control. He had picked up an injured hawk and wanted to know if I could receive it. Half hour later he delivered to me a juvenile male Red-shouldered Hawk. It was immediately obvious that the little guy’s injuries were serious. His left foot had several punctures, and the whole foot was infected and swollen to the point of disfigurement. His wounds were probably a week old, and he was severely dehydrated and emaciated from being unable to hunt and take care of himself over that time.

The puncture wounds appeared to be the work of a prey animal; most likely a squirrel. If the hawk does not land on the squirrel’s head and kill it quickly, the squirrel can get the upper hand. Fighting back with all the power of its nut-cracking teeth and jaws, a squirrel can be a formidable opponent to a small hawk such as a Red-shouldered. This hawk, in his youthful naiveté, had apparently made the mistake of holding on too long and his would-be prey got a hold of him. I started him on antibiotics and pain meds, cleaned his wounds, and began fluid therapy to rehydrate him before I could offer him any food.

That same afternoon I received another male Red-shouldered Hawk (bringing my Red-shoulder count up to five), an adult, transferred from Second Chance Wildlife Center in Gaithersburg, MD.  His history was another mysterious case. He was found in a yard in Chevy Chase, MD on Feb. 17, where he had been seen all day, “flapping his wings but not flying.” The examination suggested that he had suffered an impact. There was blood in his trachea (wind pipe), and he was very weak and unsteady on his legs, preferring to rest on his hocks. Like the juvenile, he had probably been down for some time, because he too was emaciated. Second Chance had treated him with non-steroidal anti-inflammatory (NSAID) drugs and fluid therapy, and after ten days he had regained some of his strength, was eating on his own, and ready for outdoor housing. I placed him in the mew with Squeak-toy.

I call Squeak–toy’s new roommate “Bob”, because of the strange bobbing movements he made with his head when I first put him outdoors. His legs were unsteady and he wobbled when he landed on a perch. He would raise and lower his head, looking at his feet, to maintain his balance. Bob is still not 100 percent, but his condition is greatly improved. When he first went out, he lacked strength in his wings as well as his legs. His flight was balanced, but he could not gain enough height to fly to the highest perch. Now he is flying circles over me when I enter, and landing on stronger, sturdier legs. Speaking of making it to the highest perch, Squeak-toy is getting there now too! I am pleased and proud that he is still making progress on his own.

The morning after I received the two hawks, I got a call from Wes. Wes had rescued a Barred Owl from the side of Interstate 70 in Mount Airy, MD, where he exited on his way to work. He continued driving to work where he modified a box, placed the owl in it, and called Animal Control to pick it up. Then he found Owl Moon Raptor Center on the MD Dept. of Natural Resources website and decided to cancel the call to Animal Control and bring the owl to Owl Moon himself.

The Barred Owl, a male we call “Zen,” was unusually calm and alert on arrival. In my initial exam I could feel unnatural movement in the elbow joint of his left wing. Any injury in the area of a joint is serious, but I could not feel a fracture. It was Monday, so I called my vet, Dr. Barb Stastny at Opossum Pike Vet Clinic, and arranged to bring the Barred owl, and the juvenile Red-shouldered Hawk with the infected foot, to her for examination. The owl’s X-ray showed some separation in the joint, probably from the swelling, and possibly a “chip” fracture at the tip (olecranon process) of the elbow. We started him on NSAID drugs to alleviate the pain and inflammation. We will keep him quiet, on cage rest, for a couple of weeks, and gradually begin some gentle physical therapy to try to prevent stiffening in the joint that would limit range of motion.

Dr. Barb did not like the look of the Red-shoulder’s foot anymore than I did, but we decided to try him on antibiotics and pain meds for a week, soak his foot daily and keep it in a ball bandage, and see how he responded. Unfortunately, the foot barely improved even with these intense treatments. It remained deformed and he could not use his toes at all.  I brought him back to Dr. Barb and she took X-rays. We found that the infection had entered the bones of his digits and two of the digits were luxated. Sadly, nothing we could do would give him back the use of that foot, and he would continue to suffer severe pain. We made the humane decision to euthanize him.

Meanwhile, Zen’s injured wing seems to be improving. We don’t want him using it at this stage, so we can’t test his flight, but he flaps it now when he can get away with it. The elbow is still swollen, and though range of motion in the joint is restricted now, we are cautiously hopeful that Zen could yet regain full flying ability. We will continue to keep him quiet and do gentle physical therapy, and give him more time to recover.

Sonya, the adult female Cooper’s hawk that impacted with a car three weeks ago, is still on the mend. I took her back to Opossum Pike Vet Clinic last Friday, March 9, for follow up X-rays. Dr. Barb had hoped that the compound fracture in her left leg might have healed enough to remove the pin, but while a callus is forming, it has not completely “bridged” at one of the fracture sites, so she left the pin in place and replaced the splint, to keep the leg immobilized. We will return after two more weeks to have the pin removed. Both Sonya and I will be very relieved when she can tear apart her food and eat on her own again!

Tomorrow I am off to Baton Rouge, LA, for the 2012 National Wildlife Rehabilitators Association Symposium. I will watch and listen to presentations by rehabilitators, veterinarians, biologists, and educators from all over the country about many topics of concern to wildlife rehabilitators. This year there is a session devoted to reuniting and fostering baby birds and mammals, a topic near and dear to me. I always learn so much at these symposiums, and come home feeling renewed and invigorated. It comes just in time to take on raptor nesting season, which is already underway. Thank you to my husband, Jan, for taking over many of my duties, as well as my friend Kathleen Handley, another wildlife rehabilitator, who will handle any and all medical treatments in my absence. I look forward to reporting back to you all next week.

PS. I also get to do a bayou boat tour! Can’t wait!
