Raptor Monitoring - Lesser Spotted Eagle (1990 - 2010)

Since 1990 - I control a 420 square kilometer area in NE-Germany on raptors. Specific studies are here for Lesser Spotted Eagle (Aquila pomarina) and Hobby (Falco subbuteo).
2010 was a very successful year for the LSE in the study area: 
15 occupied territories (RP),
13 pairs (BP) have begun with the brood (87%), 
10 pairs were successful (0,85 juv.*/BP; 0,73 juv.*/RP - * = one pair with 2 juv.).
The LSE population varies between 2,4 - 4,0 RP/ 100 square km. 
In 2010 there were 3,6 RP/ 100 square km.
This clutch was over-brooded. Photo: 08.07.2010 - note fresh branches of oaks and down feathers from female.
This young LSE is about two weeks old - note the very fresh branches of spruce.

Hobby (female) - These beautiful Falcons breeds with 6-8 BP in the area.
Marsh Harrier (male) - Marsh Harrier is a regular breeder in the monitoring area.
The Black Kite broods with 3-4 pairs in the monitoring area.
Honey Buzzard (female) - The monitoring area is one of the best places for Honeys in MV. Is a breeding ground for up to 28 pairs (6,7 BP/ 100 square km in 2005-2008).
The Red Kite is typical breeder in the monitoring area. The breeding population varied in the past 20 years with 48 - 55 pairs (11,4 - 13,1 pairs/ 100 square km). All images by Carsten Rohde 2010 and 2011.
