Identification of wintering birds of Yazd artificial wetland
author
Abstract:
In the present study, the wintering birds of the artificial wetlands of Yazd province in 1393, 1395 and 1396 were studied. This study is one of the first studies conducted with the aim of preventing the drying process of the wetland by emphasizing on maintaining water rights and protection of migratory birds in the artificial wetland of Yazd. Data from winter and autumn counts which were carried out in 2014, 2016, and 2017, were gathered and analyzed. In this study, 48 bird species (18 species of aquatic, 18 species of waterside and 12 species waterside) were identified. The highest numbers belonged to the Fulica atra (528 individuals), Sturnus vulgaris (500 individuals) and Anas platyrhynchos (130 individuals) respectively. Among aquatic birds, the highest number of species were represented by the family of Scolopacidae (6 species). Furthermore, the family of Rallidae represented the highest number (531 individuals comprising of 3 species). The highest and lowest numbers were 2750 and 819 individuals in 2017 and 2016 respectively. The highest evenness was observed in 2016 (0.62) and the lowest in 2014 (0.39). The most diversity of Simpson and Shannon-Winer in 2016 were 4.32 and 2.01 respectively. This study has shown that the artificial wetland of Yazd, in addition to protecting and maintaining water birds, is also important for the conservation and providing habitats for terrestrial birds and thus protecting it should be of utmost importance.

every year a large number of migratory wintering water birds, rest in the wetlands situated in the northern provinces of iran. the wetlands are very important ecosystems for these creatures. due to ecological importance of water birds, the results of this study (the birds’ populations and their changes) are helpful to monitor them and are especially important to manage the wetlands. in this stu...

Background: Investigating the performance of naturally operated treatment plants may be due to the fact that they cannot be operated as desired, or that they should be modified to achieve good performance e.g. for nutrients removal. The advantage of kinetic coefficient determination is that the model can be adjusted to fit data and then used for analyzing alternatives to improve the process. Th...
full textPredicting Occupancy of Wintering Migratory Birds: Is Microhabitat Information Necessary?
Information regarding microhabitat, here defined as small-scale vegetation structure, is often useful in predicting use of habitat by birds. Quantifying microhabitat, however, is expensive and labor intensive compared to assessment of habitat at a larger scale, possibly from remotely sensed imagery. To assess the importance of microhabitat information in constructing predictive models of habita...
full textEffects of Prescribed Burns on Wintering Cavity-Nesting Birds
Primary cavity-nesting birds play a critical role in forest ecosystems by excavating cavities later used by other birds and mammals as nesting or roosting sites. Several species of cavity-nesting birds are non-migratory residents and consequently subject to winter conditions. We conducted winter bird counts from 1998 to 2000 to examine the abundance and habitat association of cavity-nesting bir...

Many small passerines are resident in forests with very cold winters. Considering their size and the adverse conditions, this is a remarkable feat that requires optimal energy management in several respects, for example regulation of body fat reserves, food hoarding and night-time hypothermia. Besides their beneficial effect on survival, these behaviours also entail various costs. The scenario ...
