Birds are feathered, winged, bipedal, warm-blooded, hard shell egg-laying, vertebrate animals. Birds range in size from the 2 inch Bee Hummingbird to the 9 foot Ostrich, however neither of those extremes are found wild in Connecticut. Birds have a high metabolic rate, a four-chambered heart, and a lightweight but strong skeleton, which enables them to fly.
Connecticut has about 417 bird species as of the current count, though that number can vary somewhat depending on who you ask and what is considered a valid record. There is a diverse selection of bird types in this state, including ducks, hawks, sparrows, gulls, warblers and many other families of birds. Connecticut has many dedicated groups of Birders, professional and amateur, year round counting the sightings and helping others to learn how to identify them.
In Connecticut the most common duck is generally the Mallard. The most common seagulls are the Ring-billed Gull and the Herring Gull. The most common hawk is the Red-tailed Hawk, and the most common sparrow is generally the House Sparrow. Robins, Blue Jays, Cardinals and American Crows are also very common. These species can generally be found year-round.
