Abstract Khorasan Razavi province, including important habitats for marbled polecat (Vormela peregusna) in Iran. in this study, we used maximum entropy method (Maxent) for habitat modeling in the province. This method is an effective approach for habitat modelling with presence points. In this study, 25 points were used and 89 percent accuracy was achieved. Based on the results, the northern and northwestern regions of the province are more suitable for the species. According to the study, 6% of the whole province is suitable for the species. The results also showed that the suitable habitats areas overlap with roads and in addition to roads with human settlements such as towns and villages also showed a positive relation and in according to the responses curves, with increasing of distance of the areas, decreasing habitat suitability. And also, forest areas and rivers have a positive effect on habitat suitability. According most environmental degradation is about habitats, so we must try to survey and management these areas appropriately.

Status and distribution of breeding birds in Iran is poorly known, especially in the north-east of Iran. In this study we present the result of our long-term field observations of breeding birds in northeastern Iran, Khorasan-e-Razavi province (Mashhad County, Sabzevar County, Sarakhs County, Dargaz County, Quchan County, Torbat-e Heydarieh County) since 2008. We confirmed the breeding status of 54 bird species, some of which, namely Egyptian Vulture Neophron percnopterus, Saker Falcon Falco cherrug, Asian Houbara Bustard Chlamydotis macqueenii and European roller Coracias garrulus are threatened. We believe that the number of breeding birds in Khorasan-e-Razavi province is much higher than reported here, but further observations and evidence is required to confirm the exact number. Due to the importance of uniform data collection and monitoring of breeding birds, we provide a framework for recording these data within Iran.
