Received 2 February 2013 To promote this activity, this papers aims to review all available Accepted 15 March 2014 information on the migration routes of birds in Iran derived from radio- tracking techniques. To concentrate more on bird groups, we have Keywords focused on waterbirds and raptors, and exclude information on the Asian Bird migration Houbara Bustard. Five species of waterbirds and seven species of raptors Radio-tracking have been tracked entering or crossing Iran. Raptors Waterbirds 1. Introduction the world (Berthold et al. 2001). In Iran, bird Iran lies at a strategic location at the ringing scheme was as one of main programmes convergence of three major faunal regions in the Department of the Environment (DOE) (Firouz 2000). The migratory elements of during the 1970s. This scheme resulted in Iranian birds are: summer visitors, winter obtaining good results in bird migration of visitors, passage migrants, and internal migrants Iranian birds (Argyle 1975, 1976, Cornwallis & within Iran (Scott 1989, 1995).

Waterbirds on through Khorasan to Zahedan, Sistan & Only five species of waterbirds, namely Greater Baluchestan. The third bird passed through Flamingo Phoenicopterus roseus , White Stork Khorasan to the southeastern coast of Ciconia ciconia , Siberian Crane Grus Hormozgan, and returned to the Samara region leucogeranus (Fig. 1), Crab Plover Dromas via the same route. The fourth bird migrated ardeola (Fig. 2) and Little Ringed Plover along the west coast of the Caspian Sea through Charadrius dubius , have been followed by central Iran to the southwestern and radio-tracking in Iran. southeastern coasts of Pakistan. These contrast Two Greater Flamingos crossed into Iran with the two birds that were tagged much from Al Wathba, UAE, in 2006. The first data further to the east, in the Omsk region of from Iran were obtained from Neiriz lake on 4 Russia, and migrated southwestwards. One bird March 2006 where a bird stopped for nearly ended up in an area near Charmahal & two weeks. It was then recorded near the Bakhtiari, southwest Iran (Chernetsov et al. Caspian Sea coast in south-western 2004). Three other White Storks fitted with Turkmenistan in early June (Javed et al. 2006; transmitters in Armenia crossed western areas Fig. 1). Another bird from the northeast of UAE of Iran to reach Khuzestan Province (Acopian crossed into Iran at Bandar Abbas, then Centre for the Environment, unpublished map continued through Fars Province and central released on 17 October 2013).

It then surprisingly migration from Fereidoon-Kenar and passed crossed the Caspian Sea and reached through somewhere around Rudsar, Gilan northeastern areas of the sea in Kazakhstan Province and the Azerbaijan Republic coasts (Anonymous 2012a; Fig. 1). The data obtained and stopped at Kizliyar, northwest of the from satellite-tracking provide precise Caspian Sea, before continuing on along the information on routes taken rather than just the north coast of the Caspian Sea to the region of ringing and recovery sites obtained from Obzhorovskiy, at the eastern end of the Volga ringing data. Ringing recoveries have revealed River delta. The bird took 56 days for its that many Greater Flamingos from the Lake migration from Iran to its presumed breeding Tenghis colony in Kazakhstan reach Iran, area to the east of the Ural Mountains, Russia, especially the south-east Caspian region, while near the northern border of Kazakhstan (Kanai young birds from the Lake Uromiyeh colony et al. 2002). Ten birds that had been reared in have been recovered from 27 countries as far captivity were fitted with transmitters and afield as southern Europe (Italy), the Western released in winter during the period 1996/97 to Mediterranean (Tunisia and Morocco), East 2008/2009, but the results were very limited. In Africa (Ethiopia, Sudan, Somalia and Djibouti) the winter of 2003, a bird fitted with a PTT and the Bay of Bengal (India and Sri Lanka) migrated from Fereidoon-Kenar to Azerbaijan and do not show a preference for any particular Republic and Daghestan (Russia). Another bird direction (Cornwallis & Ferguson 1970, Argyle with a PTT migrated from its wintering site but 1975, Behrouzi-Rad 1992, 1993, D.A.

Migration routes of Crab Plover (Bom et al. 2013). A study involving Crab Plovers showed that of 12 wintering individuals at Barr al Hikman, Oman, tagged with loggers transmitting data via a local wireless network, two moved northwest along the north coast of the Persian Gulf.
