Diet composition of lesser kestrels in Ikh Nart Nature Reserve, Mongolia

Aralık, Iğdır (Doğu Anadolu Türkiye)'da küçük kerkenez (Falco naumanni Fleischer) diyeti hakkında ön veri

“…In this study, lizards and small mammal prey rates in the diet composition of Lesser Kestrel were found to be in low levels when compared with insect taxa. Depending on the insect intensity in the habitat of Lesser Kestrel, low rates of reptiles and mammals can increase in the diet (Ganbold et al, 2017). According to Ananian (2009), in a study conducted by Lyaister and Sossin (1942), unlike the present study, small rodents and lizards formed the main prey in the pellets of Lesser Kestrels which were obtained from the same habitat in the present study.…”

“…A great number of studies conducted to find out diet composition show that a great part of Lesser Kestrel consists of insects (Lepley et al, 2000;Kok et al, 2000;Khaleghiadeh and Javidkar, 2007;Pérez-Granados, 2010;Rodríguez et al, 2010;Ganbold et al, 2017;Di Maggio et al, 2018). In this study, we determined 108 individuals belonging to three families of Insecta.…”

“…In addition, in a study conducted in a semi-desert area in Mongolia, Ganbold et al (2017) reported that the diet composition could have insect and reptile taxa rather than sunspiders. We reported a low rate of reptiles (2.75%).…”

Estimating Occupancy and Detectability of Toad Headed Agamas at the Periphery of Their Range in Mongolia

“…Habitat types represented the two major land cover types in the region, and we predicted that forb-dominated areas would positively affect occupancy because they offer greater opportunities for vigilance against predators and concealment, which would probably not be the case for grass cover (Ananjeva et al, 1997;Rogovin et al, 2001;Terbish et al, 2006b). Similarly, we expected taller vegetation would limit vigilance, especially against aerial predators such as Lesser Kestrels and other diurnal raptors, and negatively influence occupancy (Ganbold et al, 2017). Soil type represents an important consideration for burrowing, and both sand and gravel are frequently used, so we assumed both would positively affect occupancy but to varying degrees (Shenbrot et al, 1991).…”

“…During winter months, agamas hibernate; in Mongolia, the species typically emerges in April/May and is active until September/ October. Toad Headed Agamas also represent an important food source for predators, including threatened species such as Lesser Kestrels (Falco naumanni) (Ganbold et al, 2017), and their burrows probably provide shelter for insects and other lizards and contribute to soil aeration and regeneration (Ananjeva et al, 1997;Terbish et al, 2006b).…”
