Birds get their colors from various pigments and feather structures. One of those three pigments seen in birds is melanin. Melanin occurs both in a bird’s feathers, but also their skin. Depending on the concentration of this pigment, different colors can be produced. From being more sparse, which can include colors such as reddish browns…
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 eggs are a very unique period in a bird’s life. They, like birds, come in a wide variety of colors and shapes. They have their own unique adaptations to give them the best chance of making it to hatching. The egg shell’s purpose is to be strong enough to protect the baby birds growing…

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.

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….
The tomial tooth, or the mandibular tomia, is not really a tooth at all, but a projection that can be seen in the outer edge on beaks of falcons, kites, and shrikes. This “tooth” also corresponds with a divot on the lower bill, called the mandibular notch; these together act like a pair of scissors…
