Introductory study of ecological ‎charactristics some in nesting ‎habitat of Eurasian Penduline Tit ‎Remiz pendulinus in Shara ‎area, Khondab, Markazi ‎province, Iran

This study in order to introductory study of ecological charactristics some in nesting habitat of  Eurasian Penduline Tit Remiz pendulinus in Khondab Shara area of Markazi province was conducted from April to July 2018, Using of linear and point transects and statistical methods, with eight variables such as: Percentage of tree crown cover, diameter at breast height, depth of river under the nest dangling, distance from the road, distance from agricultural land, distance from the village, nest height from the surface of water and land and nest size. Results showed as if Penduline Tit’s nests 17 was observed in the area. Nests were active eight and inactive nine. The variables of tree crown percentages, diameter at breast height, river water depth and distance from the village have a significant correlation with the nesting habitat of the Pendulines and their activeness. Reduced annual drainage of the river and agricultural land development threatened the nesting habitat of the Pendulines and decline the population size of this bird.
