Wildlife Rehabilitation at the Coast and extreme eastern Coastal Plain Elizabeth L. Hanrahan WREN Wildlife Rehabilitation of Eastern NC Most of the material for this article is based on my experiences living on Ocracoke for 5 years. We will be moving back to the island in December, 2010. Mammals: For the most part there are few native, terrestrial, mammals on Ocracoke. There are no native squirrels, opossums, deer or poisonous snakes. However, someone will bring in a single squirrel over every few years. Since there is not enough “brows” the squirrels starve, or get caught by Ferrell cats. There are occasional reports of deer sightings. In five years I rehabilitated one vole and received a DOA hit by car marsh rabbit. Since there are native populations of squirrels, cottontails, opossums and deer form Hatteras Island north, there are mammal rehabilitators in Buxton, Manteo, and East Lake and on the mainland. Therefore, the focus on Ocracoke, the Outer Banks, and the eastern coastal plain is primarily on birds and turtles. Shore and sea birds are seen throughout the year. There are always a lot of pelicans, gulls, and terns in wildlife rehabilitation. In the fall, winter, and early spring there are many loons; Common and Red-throated. During the winter one can expect to receive at least one northern gannet per week into wildlife rehabilitation. In the summer Cory’s shearwater and other verities of shearwater are received into rehabilitation. Some years there may be a “fall-out” of juvenile, primarily, male shearwaters. Numerous studies by both the University of Wisconsin and the University of Georgia indicate that these young birds overextend themselves by straying from the flock and do not have the fishing skills needed for independence. Many of these birds arrive into rehabilitation dehydrated and emaciated. Therefore, the standard rehydration and emaciation protocols are followed. The recommended transition to “whole foods” by the IWRC following rehydration is: ¼ tsp. of Pancreatin half-cup pureed low-sodium water-packed tuna or steamed fish filets. Incubate the formula to body temperature for 15 minutes before feeding. Pancreatin must be mixed with food. Supplement with water and an appropriate avian vitamin, and 1/8 tsp live culture yogurt. Sea Tabs® (Pacific Research Laboratories, Inc., El Cajon, CA) is the recommended for all fish eating birds, turtles, fish and sharks. In addition all birds that are consuming previously frozen fish should have a dose of Vitamin B Complex daily. |

In the Spotlight
TALES FROM THE FIELD Squirrel Delivered by Cab by Ann Rogers, Triangle Wildlife Rehabilitation Clinic I got a call from a woman in Hillsborough whose cat had brought her a young squirrel. She told me that she has back problems and cannot drive so she could not bring it to me. She lives 30 minutes from me, and I was feeding so many birds and squirrels that I did not have an extra hour to go pick it up. (I was also sort of irked that her cat brought it in and wanted her to take some responsibility for it!) I asked if she had a friend or neighbor who could bring the baby to me, or at least meet me somewhere closer. Then she remembered that she had used a cab to get to a hospital appointment recently and said she'd call Tony's Taxi service (a one-man operation) and see if he would deliver the squirrel. She called back and told me that he would bring it and that she would use an old carrier that I wouldn't have to send back to her. In a few hours, the cab showed up with the carrier and I ran out to meet him and asked if I could take his picture. The 100g, eyed-opened squirrel was in good condition and is now named "Taxi", although I quit naming my squirrels years ago! I thought his whole episode was funny and mentioned it on the Wildlife Welfare Yahoo group. Someone suggested I should call the TV station, which I ignored. Obviously, someone else decided it was a good idea! The next day, I was working a shift at the Triangle Wildlife Rehabilitation Clinic, and of course, took my baby squirrels with me to feed. I got a call from WRAL and they asked it they could come get a video of my squirrel who arrived in a taxi, so they came to the clinic to make the video. It aired that night and all the next day on two local stations ( http://www.wral.com/news/local/noteworthy/story/8128582/ ), and was picked up by other stations across the country. I also heard from several friends in other states who saw the clip! "Taxi" now weighs almost 200 grams and is in a juvie cage with two other younger squirrels. |
Trophic Feeding Categories of Songbirds Introduction Elizabeth L. Hanrahan
The digestive system in birds is fast because they cannot store heavy food materials for long periods of time. They need a constant supply of nutrients to sustain activity. The bill is used to crush, tear, or simply hold food before swallowing. Most birds have few taste buds; passerines have about 6. Birds are able to make distinctions in foods based on the feel, or texture, of the food to the tongue and palate. The esophagus is a simple muscular structure connecting the mouth with the proventriculus or glandular stomach. In some species the proventriculus has been widened for temporary food storage and is called the “crop.” The “crop” allows birds to load up on food quickly and then fly off to digest in safe cover. Most granivores have an enlarged crop; think doves and pigeons. Some birds have evolved a complex stomach (proventriculus and ventriculus) below the “crop.” The proventriculus is a glandular area of the stomach that produces the mucus, pepsin and hydrochloric acid needed for digestion. The tough, muscular section of the stomach, the gizzard, acts as teeth grinding food into a soft pulp and blocks the passage of bones or other objects that may injure intestinal tissues. Granivores, birds that eat grains or small seeds,have a well developed proventriculus and gizzard. Evening Grosbeaks, which feed on heavy nuts and seeds, need a substantial gizzard to crush food into particles small enough to digest. Frugivores, such as Waxwings and Bluebirds, and birds that specialize in fruits and berries have a reduced gizzard. Fruits and berries are rich in simple sugars and require little digestion and pass rapidly through the bird. Birds in rehabilitation are in our care because they are sick, injured, or young. Healthy adult, unstressed, birds may tolerate brief periods of inappropriate diets. Young or compromised birds have little margin for error. Nutritional intake can dictate weather the bird thrives, survives illness, heals from injury or is released and lives long enough to reproduce in the wild. Wild birds have evolved to require very particular biochemical nutrients found only in a natural diet. Wild bird’s requirements for water, protein, energy, vitamins and minerals must all be met. These requirements vary between species and individuals depending on: Age, Activity Levels, Reproductive and Health status. All birds that are fed by parents, and many precocial birds, ingest foods that are unlike foods they will consume as adults. Newly hatched altricial birds require extra water, microbes, and foods specific to them. All hatchling birds, until day 4 need digestive enzymes added to their diet. Pancrezyme® or Viokase-V ®, available from your veterinarian, can be given. Many wildlife rehabilitators substitute, plain, active culture yogurt at ½ tsp. per half-cup of formula. At this time WRNC recommends the FoNS Diet or Mac Diet for nestling and juvenile passerines. As the bird gets older gradually offer a larger variety of natural, species specific foods.BEGINNER BASICS

Chimney Swifts Depend On Us, and We On Them!
With the help of WRNC's Chimney Swift Tower Grant Program, construction of alternative habitat for our feathered environmental partner, the Chimney Swift, continues to spread across our state. 2010 WRNC grant award towers were erected in Cary and Hubert, NC much to the chagrin of insect pests far and wide. If you have noticed the loss of Chimney Swift habitat (possibly due to the capping of chimneys) or a decrease in numbers of Chimney Swift presence, you may also want to construct and maintain a Chimney Swift tower in your area to encourage Chimney Swifts, acrobatic insectivores who vacuum the sky at dawn and dusk, to return to your community each year. WRNC offers a $300.00 grant to assist you or your group in the undertaking of this valuable conservation project. Please refer to WRNC's website http://ncwildliferehab.org for details of eligibility and application requirements. This program is open to North Carolina residents only, at this time. For further questions feel free to contact the WRNC Chimney Swift Tower Grant Program Coordinator, Linda Bergman, at 910-346-8345 or lbergman@ec.rr.com. Deadline for submission is January 5th, annually, and as fast as the Chimney Swift flies, so does time!
An Injured Purple Martin Rejoins His Flock at Manns Harbor in Time to Prepare for the Flight to Brazil Purple martins are still being injured and killed on the old Manns Harbor bridge, but one victim recently and rejoined his flying community in time for their journey to Brazil later this summer. In spite of flashing yellow lights and a 20 mph "go-slow" zone on the western end of the William B. Umstead Bridge between Manns Harbor and Roanoke Island, some 8 to12 of the purple martins who roost there are killed each day, most likely by passing motorists, according to informal counts taken daily by the Coastal Carolina Purple Martin Society (CCPMS). The death toll is far less than the number of birds killed before the dawn and dusk speed reduction zone was introduced in 2007. Before then, CCPMS surveys counted as many as 50 birds killed per day. One year the tally was about 3,600 for the summer season (July to September) when, for at least 30 years, more than 100,000 martins from throughout northeastern North Carolina gather to roost under the bridge, fattening up before their 2,600-mile migration to Brazil. Since the CCPMS was formed in 2006, awareness of this amazing natural phenomenon has risen among local residents, who help spread the word among the summer tourists who frequent the Outer Banks. Among other programs, the Society invites people to join Thursday evening "Purple Martin Madness" sessions at the west end of the bridge, not only to witness the spectacle of 100,000 martins coming in to roost after a day’s foraging the local wetlands and farmlands, but also to learn about the history, behavior and human interrelations of the purple martins, known as "America’s Most Wanted Bird." After the July 29 evening educational sessions at the bridge, conducted at the brand new BeBop Pier and Observation Platform dedicated by Dare County Commissioners this spring, CCPMS chair Alisa Esposito made her routine check on the bridge to count martins that may have been hit by vehicles. She found six birds killed and one injured. The injured adult male suffered a deeply bruised wing, but it was not a broken wing. Alisa took the bird to the WREN wildlife rehabilitation center in Edenton for cage rest. There, she said, he was maintained on a diet of wax and meal worms fed to him every hour by clinician Elizabeth Hanrahan, who eventually offered him the opportunity to demonstrate his fitness in a flight cage. After two weeks at WREN, the martin was deemed fit for release. On August 5, during another Purple Martin Madness session at the new pier, Alisa met two young birders from Mansfield, Ohio. Eight-year-old Zoe Saldana and her sister Ava, 5, were watching the birds with their parents and grandparents, who live in Kill Devil Hills. Alisa asked the girls to help her release the rehabilitated bird to the roost. Zoe and Ava were thrilled to hear the story of the purple martins," Alisa said. "Their eyes lit up as they watched him fly up and away into the sunset over Croatan Sound toward his familiar roost." Esposito noted that about 75 percent of Manns Harbor martins are hit by vehicles traveling during the hour surrounding sunrise. "If motorists must be aboard this bridge when the birds are present," she said, "please slow down to 20 miles per hour to keep these birds safe." The go-slow zone will be in effect at dawn and dusk hours until the martins are gone, which can be anytime between the third week of August until the second week of September. Their migration is timed according to seasonal rainfall and insect population, as well as when the winds are in their favor. Dead and injured purple martins have a profound effect on people. Because they rely solely on nest houses and gourds maintained by humans, all martins at the Manns Harbor bridge come from the yard of someone who enjoyed seeing them there all spring.

ETHICS CASE STUDIES
Deciding Right from Wrong
Case Study # 15
The wildlife rehabilitator has been licensed to work with both mammals for over 7 years. She has an excellent reputation and loves working with all animals; especially bunnies. She refuses to do any euthanasia. Because of this some other wildlife rehabilitators in the area frequently transfer difficult cases to her. They don’t like to do euthanasia, either. And,” it is just too “expensive to have the vet do it.” Money is getting tight because she has 17 non releasable squirrels, opossums, and rabbits to take care of in addition to the ones that come in and are released.

Answers to previous ethics case
Case Study # 14
The wildlife rehabilitator loves working with birds; she worked so hard to get a Federal Permit. So far she has 2 robins, a cardinal, 3 mocking birds and a yellow bird in rehabilitation. She takes a photo, for her records, of each bird at admission and just before release. There is not much information on the yellow bird. It was found in the county off Hwy 64. It could be a goldfinch, a flycatcher, an oriole or some kind of warbler. She takes the bird to a golf course for release hoping it is a goldfinch. Later she shows the release picture to a friend who IDs it as a prothonotary warbler. “Did you release it by the river or at the Mill Pond? They are special and live in a riparian habitat.” her friend asks.

CREATURE FEATURE
Northern Flicker - Colaptes auratus
AdultsDescription: Flickers are large (12.5 “), distinctive woodpeckers often seen on the ground in open areas, open woodlands, and suburban areas. They have a brown crown and gray face, barred back; spotted underparts, and a black, crescent bib. Males have a black moustache stripe and a red nape crescent. Their white rump patch is conspicuous in flight. Monogamous. Will perch like a woodpecker, can perch like a passerine.
Weight Range: 92 to 130 grams
Range: Common throughout the U.S.
Natural History: Northern Flickers nest in cavities, as well as posts, poles, and boxes, excavated by both the male and female. Cavity nests are built in “snags,” standing dead trees, from 6’ to 15’ and, occasionally, up to 100’. The cavities are situated below the surrounding tree line near open ground for optimal feeding. Flickers are the most terrestrial of North American woodpeckers
Adult Diet: Insectivore. Insects, eats more ants, more than 3,000 per day, than any other N.A. bird. Also eats seeds, acorns & nuts. Gleans bark and ground for insects. . May be fed mealworms, waxworms, and suit cakes while in wildlife rehabilitation.
Nestlings: Altricial and naked. Skin is warm brownish-orange becoming reddish then blackish before feather quills appear. Inside of mouth is pink. Swollen, whitish, gape flanges. Quills appear at 7 days, eyes open at 10 days. Young brooded by male for first 3 weeks. Fledge at 25-28 days. Young feed by regurgitant by both parents.
Fledglings: Become aggressive toward siblings. Will make a “Kerrr” sound with head bobbing when feeding. May injure siblings. Do not house with other species.
Juveniles: Juvenile flickers admitted to rehabilitation can present difficult behavior problems. They are not independently self-feeding and will not gape for food. The mouth is easy to open for force-feeding. Introduce natural foods as soon as possible to speed independence.Rehabilitation Notes: Activity Aviary requirement=8’ x 16’ x 8’. Provide upright logs and large limps for climbing. Provide additional branches for perching. Flickers enjoy a “cavity” for occasional shelter.
Common Problems: Frequently nest or glean decayed trees that can fall during windstorms; nestlings can be orphaned or injured as a result. Nestlings frequently infested with ectoparasites or mites. Because they are frequently on the ground they may be struck by cars when foraging for ants on the shoulder of a road. Because they forage in suburban lawns they are prone to pesticide or fertilizer poisoning.
