A bird’s beak can have different components to it depending on the species or bird family. On gull species, where the two lateral plates of the lower mandible connect towards the tip of the beak form a ridge or bulge called the gonydeal expansion. This bulge also causes a bump out on the lower mandible…
In a previous blog post I went over some of the many different shapes a bird’s beak may have and how they are adapted to their diet, but I never went over what parts of a bird’s beak actually are. They are an important part of the topography of a bird and to truly appreciate…
Bird banding can provide valuable data on several fronts. From monitoring populations in an area, studying migration and various other study and research programs. So how does bird banding work? A typical day of bird banding for passerines (songbirds) starts before the sun rises, and in our case, that means 4:45 am. It’s still dark…

Many times when you think of a bird’s nest, you think of a structure in a tree made of sticks, moss, and various other plant materials.

These little songbirds are as brightly colored and diverse as their musical songs, whistles and trills. This colorful group is the parulidae family, also called the new world warblers or…
One of the more common large birds you may see overhead throughout North America is the turkey vulture, especially in the spring as they migrate in large numbers northward. One of their features to help identify them when they are in flight, even if they are at a great distance away, is their flight style….
While out hiking in a field, you spot a little american kestrel in a telephone wire. Its back is to you and you notice an interesting pattern on the back of its head, which appears to resemble eyes. These feather patterns aren’t eyes though, they are called ocelli, or false eye spots. This adaptation can…
For birds to survive, they need keen eyesight, to find food, to navigate their environment, find a mate and avoiding becoming something else’s meal. So it is critical to protect their eyes, especially when flying through the air and through vegetation where there is an increased risk of something hitting their eyes and causing abrasions….
Birds of prey have excellent vision, they need it to be able to see prey from perched in a tree or soaring high above the ground. Though, something can get in the way of their vision, making it difficult to clearly see, especially when out in the open, and that is the sun. Many times…
