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…

Bird Anatomy: Beak
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…
Growing Up Bird: Eggs
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…
A Day Bird Banding
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…
Bird Family: Parulidae
One of the highlights in spring is going birding to see and hear the colorful songbirds that have migrated back from their southern wintering grounds. 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…
Bird Anatomy: Nictitating Membrane
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….
Bird Anatomy: Supraorbital Ridge
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…
Bird Anatomy: Lamellae
If you look at the bills of some duck species, you may see it lined with fine comb-like structures. These little projections are called lamellae and are made of keratin. These slightly flexible structures are used to filter and strain food from mud or water. These structures will be seen mostly in dabbling ducks along…
Bird Anatomy: Tomial Tooth
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…
Bird Anatomy: Ear Tufts
In the bird world, if you say ear tufts, you would probably instantly think of the ear tufts on owls. This feature is found on many owl species, about 50 of the 200 plus owl species have ear tufts, seemingly mostly occurring in nocturnal, forest dwelling species. But there are many other species that possess…
