<abstract xmlns="http://www.w3.org/1999/xhtml"><p> During the period 2008-201 3, 32 different breeding territories were occupied by eastern imperial eagles (EIEs). These territories were mainly distributed in two regions: the Dervent Heights/Yıldız Mts. and the area to the north of the Marmara sea coast. The nearest neighbour distance established was 4.2 km. The mean distance between pairs was 1 0.44±2.95 km. The mean value of breeding success for the period 2008-201 3, including 1 07 cases of incubation, was 1 .01±0.1 0. The mean breeding success of birds in the Marmara region (1 .05±0.78) was higher than that in the Dervent Heights/Yıldız Mts. (0.91±0.84). The present study on the diet of the EIE was based on the remains of 582 prey items of at least 70 taxa. Mammals were the most common group (46.5%), followed by birds (32.4%) and reptiles (20.3%). The white-breasted hedgehog (Erinaceus roumanicus) was the most common prey, followed by two tortoises - Hermann's tortoise (Eurotestudo hermanni) and the Greek tortoise (Testudo graeca) - which together accounted for a total of 1 4.4% of the prey caught. The prey species particularly represented in the food spectrum of the studied pairs were: the yellow-legged gull (Larus michahellis), the European souslik (Spermophilus citellus), the chicken (Gallus gallus f. domestica) and the white stork (Ciconia ciconia). These species together accounted for 67.8% of the prey caught. There was a statistically significant difference (Z=2.52, p=0.01 ) in the food preferences of the EIEs in the two studied regions. </p></abstract>
