The western jackdaw is found from north-west Africa through all of Europe, except for the extreme north, and eastwards through central Asia to the eastern Himalayas and Lake Baikal. To the east, it occurs throughout Turkey, the Caucasus, Iran, Iraq, Afghanistan, Pakistan, and north-west India.he common name jackdaw first appeared in the 16th century, and is thought to be a compound of the forename Jack, used in animal names to signify a small form (e.g. jack snipe), and the archaic native English word daw. Formerly, western jackdaws were simply called daws.
Other medications that may cause leg cramps include osteoporosis drugs like raloxifene and teriparatide; intravenous iron sucrose (used to treat anemia); asthma medications like albuterol; conjugated estrogens (used to treat menopause symptoms); and pain meds like naproxen and pregabalin.
Unknown cause (idiopathic leg cramps) In most cases the cause is not known. One theory is that cramps occur when a muscle that is already in a shortened position is stimulated to contract. As the muscle is already shortened, to contract further may cause the muscle to go into spasm.
