The common gull or sea mew is a medium-sized gull that breeds in the Palearctic, northern Europe. The closely related short-billed gull is sometimes included in this species, which may be known collectively as "mew gull". Many common gulls migrate further south in winter. There are differing accounts as to how the species acquired its vernacular name.

The Italian sparrow, also known as the cisalpine sparrow, is a passerine bird of the sparrow family Passeridae, found in Italy and other parts of the Mediterranean region. In appearance, it is intermediate between the house sparrow, and the Spanish sparrow, a species of the Mediterranean and Central Asia closely related to the house sparrow. The Italian sparrow occurs in northern Italy and neighbouring regions, with intermediates with the house sparrow in a very narrow contact zone in the Alps, a slow gradation in appearance from the Italian to Spanish sparrows across central and southern Italy, and more birds of intermediate appearance in Malta, Crete, and other parts of the Mediterranean.

The EBCC Atlas of European Breeding Birds - their distribution and abundance (ISBN 0-85661-091-7) is an ornithological atlas published for the European Bird Census Council by T & A D Poyser in 1997. Its editors were Ward J. M. Hagemeijer and Michael J. Blair. The atlas was the first to present grid-square distribution maps for all breeding birds at a Europe-wide level. The bulk of the book is in English, although it also contains introductions in thirteen other European languages. The atlas presents the results of the European Bird Census Council's European Ornithological Atlas project, the fieldwork for which was carried out between 1985 and 1988.

A gorget is a patch of colored feathers found on the throat or upper breast of some species of birds. It is a feature found on many male hummingbirds, particularly those found in North America; these gorgets are typically iridescent. Other species, such as the purple-throated fruitcrow and chukar partridge, also show the feature. The term is derived from the gorget used in military armor to protect the throat.
A bird atlas is an ornithological work that attempts to provide information on the distribution, abundance, long-term change as well as seasonal patterns of bird occurrence and make extensive use of maps. They often involve a large numbers of volunteers to cover a wide geographic area and the methods used are standardized so that the studies can be continued in the future and the results remain comparable. In some cases the species covered may be restricted to those that breed or are resident. Migration atlases on the other hand cover migratory birds depict maps showing summaries of ringing and recoveries.
Whiffling is a term used in ornithology to describe the behavior whereby a bird rapidly descends with a zig-zagging, side-slipping motion. Sometimes to whiffle, a bird flies briefly with its body turned upside down but with its neck and head twisted 180 degrees around in a normal position. The aerodynamics which usually give a bird lift during flying are thereby inverted and the bird briefly plummets toward the ground before this is quickly reversed and the bird adopts a normal flying orientation. This erratic motion resembles a falling leaf, and is used to avoid avian predators or may be used by geese to avoid a long, slow descent over an area where wildfowling is practised.
