Microraptor gui,  | Genus of small four-winged paravian dinosaurs; provide important evidence about the evolutionary relationship between birds and dinosaurs |
Oviparous,  | Producing eggs that mature and hatch after being expelled from the body |
Pennaceous feathers,  | Type of feather present in most modern birds and in some species of maniraptoriform dinosaurs |
Plumulaceous feather,  | Downy feathers |
Contour feathers,  | Any of the outermost feathers of a bird |
| Down feathers, | Feathers found under the tougher exterior feathers; specialized for thermal insulation and padding |
Vane,  | The flat part on either side of the shaft of a feather |
Rachis,  | Main shaft of a feather |
Hamuli/Barb/Barbule,  | Hamuli: small hooks or hooklike projections that link barbules together: branches from the rachis; barbules; branches from barbs |
Keel,  | An extension of the sternum; runs axially along the midline of the sternum and extends outward |
Furcula,  | Forked bone found in birds formed by the fusion of the two clavicles; primary function is strengthening of the thoracic skeleton to withstand the rigors of flight |
Uncinate process,  | Extensions of bone that project caudally from the vertical segment of each rib; serve to attach scapula muscles and help to strengthen the rib cage |
Pygostyle,  | Feshy protuberance visible at the posterior end of a bird |
Airfoil,  | Structure with curved surfaces designed to give the most favorable ratio of lift to drag in flight |
Alula,  | Small projection on the anterior edge of the wing of modern birds and a few non avian dinosaurs |
Crop,  | A pouch-like enlargement of a bird's gullet in which food is partially digested or stored for regurgitation to nestlings. |
Proventriculus,  | The narrow glandular first region of a bird's stomach between the crop and the gizzard |
| Gizzard, | A muscular, thick-walled part of a bird's stomach for grinding food, typically with grit. |
Cloaca,  | A common cavity at the end of the digestive tract for the release of both excretory and genital products in vertebrates (except most mammals) and certain invertebrates |
Syrinx,  | The lower larynx or voice organ in birds |
Monogamous,  | Pair bonding to raise offspring |
Polygynous,  | Multiple males mate indiscriminately with multiple females |
Clutch,  | The number of eggs a bird has produced |
Altricial,  | Hatched or born in an undeveloped state and requiring care and feeding by the parents |
Precocial,  | Hatched or born in an advanced state and able to feed itself almost immediately. |
Migration,  | Seasonal movement of animals from one region to another |
Thermal soaring,  | Soaring in a way to take advantage of hot columns of air for warmth |
Dynamic soaring,  | Using gusts of wind to energize flying |
