Keep Our Wildlife Wild!

X-Ray of Patient# 1683’s right wing fracture

In September 2021, a Brown Pelican was admitted to Pelican Harbor with a fractured humerus bone in its right wing. Orthopedic surgery was performed where multiple pins were placed in cross sections across the bone to stabilize the fracture and enable the bones to fuse properly. In addition to the pins, an external fixator device was also placed at the site. This involves a piece of acrylic encased in a tube that is placed on the outside of the wing to keep the pins in place and limit rotation so the bone heals properly. This type of surgery is a huge undertaking for wounded animals, as the stress of going under anesthesia for long periods of time can cause adverse reactions. Thankfully, patient  #21-1683 made it through the surgery successfully. What followed was 6 months of hard work on the part of not just the rehab team but the pelican himself. Every day he received physical therapy and medications to aid in his healing. We had to ensure he would have a full range of motion in his wing so that he could fly, hunt for food, and most importantly, live and thrive on his own in the wild.

In March 2022, 6 months after its initial intake, release day finally came for our pelican. He had completed his physical therapy and proved to us he could fly and hunt on his own despite a persistent but benign wing droop. This is the happiest day for our rehabilitation team because it’s the culmination of all our worry and hard work. Undoubtedly, it’s the best day for the animal too! He was released with another pelican on our property here in Miami, where they flew off together, and we considered it another successful release. 

However, over the next couple of months, we got numerous calls from people worried that the pelican was unable to fly due to his wing droop. After some time monitoring him and multiple visits to the jetty, it was determined that he was not thriving in the wild due to consistent human intervention and he was brought back to PHSS for further evaluation. We decided to relocate him to an area that would not have the amount of human interaction he had in his previous release area.

 Then, we started getting calls about Facebook videos being posted of people interacting with him in various ways around the Haulover Jetty area–touching him, petting him, feeding him fish, and attempting to “help” him even though he was more than capable of taking care of himself. Despite numerous attempts of release at different locations, the pelican kept returning to the Haulover Jetty, where he had seemingly become irreversibly accustomed to being fed by humans. Because of this, he was deemed unreleasable by our veterinarians and had to be permanently placed at a sanctuary, where he will live out the rest of his life in captivity. 

Please remember when you see a wild animal, they are just that– wild. Always be sure to keep your distance, and never feed wildlife. In order to thrive and survive, they need to keep their wild instincts. When animals become habituated to humans, they no longer want to look for their own food and instead spend their time in heavily populated areas. In the case of pelicans specifically, when they start to see humans as a source of food, they end up getting hooked because they hang out in fishing areas. This results in various injuries and entanglement, sometimes ingesting the hooks themselves which can ultimately result in death. Additionally, people feed them food that isn’t meant for them which can get stuck in their throat or make its way to their stomach where it then destroys their intestinal tract because it is too big for what their bodies are supposed to eat.

The best way to be a friend to wild animals is to stay as far away as possible and let them live their lives without our influence. As always, refrain from feeding, holding, or petting wild animals, no matter how friendly they may seem. 

The Vitamin B Guarantee

Why B Vitamins are Essential in the Treatment of Animals

Written By: Samantha Martinez, Environmental Educator

Here at Pelican Harbor Seabird Station every patient admitted gets an intake exam as soon as is deemed appropriate for each animal. An intake exam is the observation of the patient and the hands-on exam, as well as initial steps of diagnosing the issue and beginning treatment for the patients that come into our care. This includes physical examinations of the patient's body, obtaining a weight, administering anti-parasitic medication when appropriate, and subcutaneous fluids with vitamin B complex. We administer a complex of these vitamins to prevent any imbalance of a singular B vitamin since each is required for independent body functions. According to PHSS’s Rehabilitation Manager Yaritza Acosta, “Usually animals are coming in with some level of stress, debilitation, and dehydration, so we give them a boost of B vitamins on intake for overall health and cell function.”

According to the NWRA wildlife formulary, B vitamins can be very useful in increasing appetite and have been anecdotally shown to help with growth in poor-doer infants, specifically baby opossums. Vitamins B2, 3, 5, 6, 7, and 8 are important for skin quality and skin barrier function. Meaning that without them, the skin would not be able to properly keep in essential fluids and keep out unwanted chemicals and bacteria from the body. These vitamins are also important for numerous micro functions throughout the animal's body such as the formation of cell membranes, the growth of epidermal cells, cellular respiration, and taking part in metabolizing carbohydrates for energy.

Vitamin B12, also known as cobalin, is also very important for liver and pancreas function. Vitamin B12 along with B6 and B1 are also essential for the maintenance of a healthy nervous system which makes them very helpful in cases of CNS (Central Nervous System) trauma. Without an appropriate amount and diversity of these nutrients, animals may experience dysorexia, alopecia in mammals, non-pliability of the skin, and nervous system dysfunction. Thankfully, with the help of our community in the forms of both medical supplies and monetary donations, we are able to continue to provide these basic vitamins and minerals along with many other much-needed medications, food, and equipment.

Wonderful Warblers

Written By: Sarah Stinson-Hurwitz, Wildlife Intake Associate

Fall migration is in full swing! Sweet little warblers are migrating all the way down to Central and South America for the winter after summering in the Eastern United States and Southern Canada. Here in South Florida, we are lucky enough to be a stopover migratory site and see a lot of these little fellas in the fall.

We often get calls at the station when a finder sees a warbler, like the Cape May warbler shown on the left, on the ground not moving. A common first thought is that it needs help — it must be suffering from a broken wing or are unable to fly. If the warbler has a visible injury, your rehabilitation center should be contacted immediately. But oftentimes, the bird is just stunned from a collision with a window or another obstacle and needs a moment to recuperate. The best thing to do when you find a stunned warbler is to stand back and observe for about 20 minutes to see if they recover and fly away on their own. If not, it's time to take a photo and call us (or your nearest rehabilitation center) to determine next steps. 

Window collisions are the second deadliest human-related cause of bird injuries (cat attacks are the first). You can do your part to aid in their prevention by putting decals on your windows where collisions occur. The decals are made using the ultraviolet spectrum which is transparent to us humans but highly visible to birds. Collisions occur because birds are confused by the reflections of vegetation and sky they see in windows, and the decals upend this illusion. We also recommend placing feeders and bird baths either within three feet, or more than 30 feet, away from windows so that when birds take off they will not hit windows at dangerous speeds. If you are interested in acquiring decals, we have some available in our online store.  You can help make the world a safer place for warblers and all birds!

Why Passerines Aren’t Pets

The benefits of re-nesting songbirds 

Written By: Samantha Martinez, Environmental Educator

Humans have the amazing ability to empathize with their surroundings. To put themselves in the shoes of beings other than themselves. This is unequivocally a characteristic that we should nurture and be proud of. However; our own empathy that is meant to be used to help those around us can sometimes harm them when we are not fully aware of the effects of our actions. The most common situation that we experience like this at Pelican Harbor Seabird Station involves baby songbirds or mammals. Today we will dive deeper into the needs of baby passerines, also known as songbirds. And remember, always reach out to your local wildlife center if you find any wildlife that seems to need help

Nestling  Mockingbirds  Calling Out For Their Next Feeding From Mom & Dad 

From February to August Each year, parent songbirds will build a nest, incubate their eggs, and invest all of their energy into raising the next generation of their species. Inevitably they will run into a few roadblocks. For instance, a strong wind may knock all of their hard work completely out of the tree, babies and all. A  few may be stumbled on by humans who are more than willing to help. Now someone's first instinct may be to take the babies home and begin to feed them. This may seem like the most logical course of action but is actually not the best way we can help and has actually been coined “Bird-Napping”. In cases of fallen nests with birds that are too young to learn to fly, re-nesting would be the best option.

But what about older birds? Baby songbirds learn to fly from the ground up and can be found hopping on the ground as they build up their wing muscles until they are able to fly. In the case of baby birds learning to fly, it may look strange to us to see a bird on the ground. However, this is a completely natural process that every songbird must go through so it is important that we respect this process and leave the fledgling birds to complete their flying lessons. While their parents may not be easily visible, they are keeping an eye out for their little ones. 

Depending on their life stage, re-nesting or simply leaving them alone may be the right answer. Information on how to renest a baby bird and identify the life stage of said bird can be found here on the PHSS website. Two videos from our website will also be included at the end of this article.

Juvenile Northern Mockingbird Learning To Fly From the Ground Up

If you are still feeling iffy about the idea of leaving the baby birds, you should also be aware of the dangers you may unintentionally be imposing on these helpless younglings. Firstly, different species of songbirds each take up a specific niche in their environment when it comes to the foods they eat and baby songbirds can be extremely difficult to identify correctly. Feeding a baby bird something other than its natural diet can lead to digestion issues, growth stunting, a weakened immune system, or even death. Secondly, being raised by people can completely take away a bird's ability to behave normally in the wild and have the proper social skills to connect with other conspecifics (members of the same species) and may prevent them from breeding in the future. Though they are absolutely adorable and if raised by people can become quite friendly, wild birds or any wild animal for that matter should never be kept as a pet if it has the potential to have a full life in the wild since wild animals are biologically on every level different from domesticated animals and have much more complicated requirements to stay happy and healthy. 

All in all, good people from all walks of life stumble upon baby birds during nesting season and hear the call for help from these younglings. It is important to keep our empathy intact and do what we can but also be aware and informed of the best ways to help these animals before our good deed goes awry. Whether that be to put them in a strawberry basket with some leaves and re-home them in the closest tree or bush and wait for mom and dad to return or if the best thing is to just leave them be so they can grow into healthy well-adjusted birds. Either way, it is important to not let our first judgment and good intentions take away the right of every wild animal to be free.

Comfy Cardinal Condo for Three

Written by: Sarah Stinson-Hurwitz, Wildlife Intake Associate

In late July, a worried citizen noticed a couple of cardinal nestlings in some tall grass. She took a look around to see if she saw the parents or a nest and she was able to locate the nest these babies fell from but their nest was too high for her to reach. She contained them and brought them into the station, and after a quick check-up, our wildlife rehabilitators determined they were perfectly healthy and renesting them would be the best next step!.

Do you know what to do when you find healthy uninjured nestlings on the ground? If the nest is out of reach and their parents are in the area (we recommend waiting a few hours to give the parents a chance to return if you don’t initially see them) a renest is the next step! Renesting is always our preferred choice for uninjured nestlings because momma birds are the best qualified caretakers for their babies. Renesting entails making a new home for babies (with a small box: cardboard, plastic strawberry carton or anything with drainage) and attaching to the tree they came from or one nearby or if possible placing babies back there original nest. https://www.pelicanharbor.org/baby-bird-help

cardinal.jpg

This is exactly what we did for our little cardinal friends. We snuggled them into a new studio apartment (with drainage of course) and sent them back with the finder to be placed securely in their home tree. The finder brought them back and ensured there was plenty of foliage overhead to protect them from the elements and that their new nest was stable. About 20 minutes after their placement, Momma cardinal heard her babies calls, settled into their new home, and provided a nice fresh breakfast.    

Finders are often worried momma bird will have trouble finding her babies after a renest, but just like humans, momma and baby alike have distinct calls (like our voices) and use them to recognize one another! If you ever find a wild animal that you think may need help, give us a call and we will guide you to determine the best course of action.
