Lesser Spotted Eagle (Aquila pomarina) Science Article 4 abstract To date there are no definite conclusions as to the age at which the Lesser Spotted Eagle Aquila pomarina reaches sexual maturity. In the course of a long-term study we were able to trap 4- and 5-year-old ringed birds in Germany and Slovakia. A 4-year-old female […]

Lesser Spotted Eagle (Aquila pomarina) Science Article 3 abstract Since about 1800 the total breeding area of the Lesser Spotted Eagle Aquila pomarina in Germany has shrunk by some 90 % from a then 83,000 km2 to a small residual area today of some 10,000km2. The western border of the breeding range has shifted several […]

Lesser Spotted Eagle (Aquila pomarina) Science Article 2 abstract Detailed observations were made of Cainism in a Lesser Spotted Eagle’s (LSE) nest, whereby this procedure generally leads to the death of the second chick a few days after hatching. The time-lapse between hatchings amounted to two and a half days (60 hours). At the time […]

Lesser Spotted Eagle (Aquila pomarina) Science Article 5 abstract Greater and lesser spotted eagles (Aquila clanga, A. pomarina) are two closely related forest eagles overlapping in breeding range in east-central Europe. In recent years a number of mixed pairs have been observed, some of which fledged hybrid young. Here we use mitochondrial (control region) DNA […]

Lesser Spotted Eagle (Aquila pomarina) Science Article 6 abstract Satellite telemetry has recently been used to track the migration of eight Lesser Spotted Eagles Aquilla pomarina and one Spotted Eagle A. clanga (Meyburg et al. 1993, 1995a and b). I used aerodynamic theory to predict the overall migration speed in these eagles using either thermal […]

Lesser Spotted Eagle (Aquila pomarina) Science Article 1 abstract In 2001-2003, the data on the productivity and diet of Lesser Spotted Eagle (Aquila pomarina) were collected in Central, Northern and Eastern parts of Lithuania. Though during the mentioned period productivity varied greatly, mean productivity of 0.61 was very similar to that more than 10 years […]
