The fish-eating birds of the north of Iran belong to 41 species in 10 families which include 67.2 percent of total fish eating bird species and 71% of fish-eating bird’s family of Iran. Resident birds constitute 13% of the fisheating birds of the Caspian Sea coasts and the rest are migratory in autumn and winter. There exist 3 globally threatened species of fish-eating birds of the world at the north of Iran, which are Oxyura leucocephala , Phalacrocorax pygmeus , and Pelecanus crispus wintering in the south coast wetlands of the region. Seventeen percent of the fish-eating birds of the north of Iran are aquatic, 5% terrestrial and 78 % wadding. The Phalacrocorax carbo and Phalacrocorax pygmeus are wintering and breeding migratory in the wetlands of the region, which feed in the fish ponds and wetlands. The main habitats of fish-eating birds are Miankaleh and Amirkelayeh wildlife refuge, Anzaly marsh and Gomishan Rams...

This survey was carried out to determine abundance and diversity of hunted waterfowl in this area. Investigation on number of migratory waterfowls was conducted using Total Count Method from January 5, 2002 till February 24, 2002 synchronized with mid winter waterfowl count (MWC), Wetlands International. Results of counting migratory waterfowls during this period declared 607914 birds form 12 family. ...

The main habitats of fish-eating birds are Miankaleh and Amirkelayeh wildlife refuge, Anzaly marsh and Gomishan Ramsar Sites. Oxyura lecucephala, Phalacrocorax pygmeus and Pelecanus crispus are protected species in Iran and the rest are not allowed to be eaten by Islamic rule, for the same reason they are not being threatened by Muslim men.

Total counted birds in Maroon lake were (971). Maximum number of counted birds was in February (191) and minimum of counted was in Septamber (95). Total counted birds in Jaizan were (385. Maximum number of the counted bird was in February (84) and minimum of counted (52) was in Januarry. Comparision of density of waterfowl and wader birds between Maroon lake and Jaizan lake shown that density was in Maroon was (0.48) bird per hectar and in Jaizan was 3.20 bird in hectar in during study time. Density maximum in maroon lake was (0.09) bird/hectar while it was (0.7) bird/hectar in jaizan lake in February. The density minimum in maroon lake was (0.04) bird/hectar in March while it was (0.4) bird/hectar in Jaizan lake in January. According to Morrista index, maximum difference between two lakes was (0.33) in January and maximum similarity was (0.64) in February. It is co...

Pour l'estimation des tendances des populations, les donnees ont ete separees en deux groupes: celles recoltees dans les annees 70 (entre 1968 et 1980) et celles recoltees dans les annees 80 (entre 1981 et 1994, 1982 excepte). Les zones humides frequentees par les especes ont ete classees «sites de valeur exceptionnelle, «sites importants» ou «autres sites» en fonction du nombre d'especes et du niveau numerique des populations qu'elles abritent. Entre les deux periodes, la population de sarcelles marbrees, Marmaronetta angustirostris a diminue, alors que celles de fuligules nyroca, Aythya nyroca, et d'erismatures a tete blanche, Oxyura leucocephala, ont augmente. Ces fluctuations des effectifs ont ete attribuees aux modifications de l'environnement, comme la secheresse et les inondations qui ont un i...

Reproductive performance in Great Cormorant was studied during the 2003 breeding season (early March-late July) at Ramsar colony. Factors influencing breeding success were taken in study. Mayfield and Maximum Likelihood methods were used to estimate nest survival during incubation stage and ...

Counting the water bird's community using the total count method with a 15 × 60 telescope and a 10 × 4 Zeiss binocular in February 2006, 2011 and 2016. Globaly threatened species are identified by the IUCN (IUCN, 2015) criteria and protected species in Iran by the Department of Environment, Iran, rules, and standards. Hor-al-Azim wetland water bird's community consisted of two types of water beds, swimmers with 21 species and shore birds with 30 species. The total number of water beds in the Hor-al-Azim in February 2006 with an area of 118,000 ha, 2011 with an area of 5000 ha., and 2016 with an area of 10,000 ha., were 18337 individuals belonging to 51 species, 2257 individuals with 33 species and 3914 individuals with 43 species respectively. Margalef species diversity for all water beds of the wetland (aquatic swimmer and shorebirds) in
