An example of a Common Grackle fledging
Guest post by second year veterinary student, Megan Stuart.
On a hot summer’s day in late May, a Common Grackle was found on a driveway in Springfield, Illinois and brought to the Wildlife Clinic as a healthy fledgling. Common Grackles are large blackbirds that have adapted well to city and surburban habitats, and are resourceful omnivores: in agricultural fields they’ll follow plows to pick out insects and mice, near marshes they will pick leeches off of turtles and wade into water to catch small fish, raid smaller birds’ nests to eat eggs and live birds, and can even use a special beak adaptation to saw into acorns and eat the insides! Adult Common Grackle males have brightly iridescent feathers of blue, purple, and bronze, but young Common Grackles do not show any sign of sexual dimorphism (distinct difference in size or appearance between the sexes of an animal in addition to difference between the sexual organs themselves), so volunteers are unsure of this fledgling’s sex.
The small fledgling received nestling care as often as possible for the first few days in the clinic to supports his growing body and nutritional needs – in some cases, volunteers will check on these young ones nearly 10 times per day! Once he had grown some more, he received little balls of food 5 times a day, and was promoted to mealworms once he showed signs of eating on his own. Since he was caged alone, the fledgling was given a mirror to encourage self-recognition, which he sat by all day and was even spotted playing with his reflection!
Towards the end of the Grackle’s stay, a fledgling American Robin came into the Wildlife Medical Clinic, and was placed in the cage so the grackle could have a feathered companion. Soon after, he was consistently eating mealworms on his own, and so the fledgling was transferred to a local, licensed wildlife rehabilitator to grow a little more before being released. All of the volunteers enjoyed working with adorable fledgling, who never turned down the opportunity to eat! He went from 48.8 grams to 89 grams while in the Wildlife Medical Clinic at the University of Illinois.

A week ago a young male intact Virginia Opossum (DIVI) presented to the Wildlife Medical Clinic for being attacked by a dog. This patient presented very bright, alert, responsive and very feisty! In order to safely and thoroughly perform a physical exam the Opossum was anesthetized. Upon physical exam a puncture wound was found on the right chest. The wound was flushed and during flushing it was noted the wound was deeper than what the naked eye could see. It was determined that a drain needed to be placed in order to decrease the risk of infection and abscess formation. A drain was placed and the patient was started on an antibiotics and pain medication. Bloodwork was obtained but unremarkable. Radiographs were obtained two days later and it was noted that the Opossum also had 3 broken ribs and bruised lungs (good thing we started those pain meds!).
Despite these injuries the patient remained feisty when awake and eating well! The drain was removed a few days later and appears to be healing well. The medications can be placed into the food and the patient can be minimally handled to reduce stress. Later next week, once the medications are finished, the drain site and bloodwork is rechecked this patient will be off to a wildlife rehabber to regrow the fur on his chest over the winter and then released back into the wild early this spring!

A juvenile snapping turtle was found in a yard and brought into the Wildlife Medical Clinic in August. He had a cut on his neck right where it joined his shell and scrapes all over the top of his shell, along with a couple of shell fractures. The neck wound was very dirty, with maggots living in it, but volunteers thoroughly cleaned it out and sutured it up. Whenever a turtle has a shell fracture, it is at risk for damage to its coelomic membrane, which separates the shell from the body cavity. Radiographs were taken to determine whether the membrane was punctured, but luckily the snapper did not have any injury to his lungs or coelomic membrane.
Snapping turtles prefer to spend their days under water in areas of vegetation, with their nose poking up just above the water surface, as if it were a snorkel. Although they can grow very large and are dangerous when cornered, they would prefer to swim away from trouble. A snapper has a long, flexible neck that can reach all the way to its hind limbs, so the safest way to handle them is just above the tail. Our patient was probably 3-4 years old, only about the size of a hand, and not very threatening. Snapping turtles do not eat very often, and enjoy fish, worms, and greens.
The turtle had a surgery to repair his shell and was placed on antibiotics. After monitoring the wounds for over a month, it was decided that they would heal nicely on their own without further care. The snapper was very excited to be released into a pond at a forest preserve and went into the water without a backward glance!
