Bosch, J. & B.-U. Meyburg 2012: The Lesser Spotted Eagle Aquila pomarina in Catalonia
(Spain) – Breeding attempt and migration. Vogelwelt 133: 89–97.

To the west of the breeding distribution range of the Lesser Spotted Eagle there are only a few
isolated breeding occurrences. In 2011 a breeding attempt was discovered in Catalonia, NE Spain,
the first ever recorded on the Iberian Peninsula. The attempt failed, but a broken egg was found
on the ground beneath the eyrie. In 2012 the nest site was re-occupied, however probably only
by the male of the previous year. In 2008 and 2009 four young eagles from the German satellite
tracking project migrated via Catalonia. The probably increased migration of the species on
the south-western flyway observed over the past few years probably led to this settlement in
Catalonia, and also earlier in France.

Key words: Lesser Spotted Eagle Aquila pomarina, Catalonia, breeding attempt, migration,
satellite telemetry.

n the period 1964-2007, data on 1472 ex. of prey was acquired from whole Slovakia. It was confirmed that the location of the breeding population on the foothills and mountains of the Carpathian Arc has a cardinal contribution to diet diversity. The breeding sites and hunting-grounds were found from 100 to 1 000 meters above sea level. The dominant part of the diet created mammalian species (88.11 %, 19 species and Sorex sp., Apodemus sp., undetermined Artiodactyla). Birds were less represented but with higher diversity of species (6.25 %, 24 species and Columba sp., undetermined Passeriformes). In comparison with birds, the share of Amphibia, Reptilia and Pisces together (4.89 %, 5 species and Rana sp., Lacerta sp., undetermined Serpentes and Reptilia) was lower. Pisces constituted only 0.007 % with 1 ex. of prey species Cyprinus carpio. Evertebrata constituted 0.75 % and species from orders Orthoptera, Coleoptera, and Diptera were found. The dominant prey of A. pomarina in Slovakia was Microtus arvalis (69.57 %), followed by Arvicola terrestris (5.16 %) and Microtus agrestis (3.94 %) constituting significantly lower proportion. These three species from the category small rodents composed 75.67 % of diet. Less abundant species in range 2.24-1.00 % were Talpa europaea (2.31 %), Rana temporaria (2.24 %), Cricetus cricetus (1.70 %), Phasianus colchicus (1.15 %), and Lepus europaeus (1.09 %). In lesser extent (1.0-0.5 %) also other mammalian species such as Apodemus flavicollis (0.88 %) and Mustela nivalis (0.88 %) were represented. The most frequently encountered birds were Galliformes such as P. colchicus (1.15 %), Gallus gallus domesticus (0.48 %), and Coturnix coturnix (0.54 %). Other more abundant prey bird species were Alauda arvensis (0.48 %), Columba sp. (0.48 %), and Crex crex (0.34 %). From the class Reptilia relatively high share of Anguis fragilis (0.95 %) and Lacerta sp. (0.68 %; most probably Lacerta agilis) were recorded. Other species with representation lower than 0.3 % were a random prey of A. pomarina.

50. Past and present nest-site requirements of the Lesser Spotted Eagle (Aquila pomarina C.L.Brehm) and their possible conflicts with timber harvesting. 2006

by Rimgaudas Treinys, Gintautas Mozgeris

Published in: Baltic Forestry, 12.2006, 2 p. 252-258

PDF available here: ... zgeris.pdf

Recently, the growing demand for raw timber has resulted in the intensification of forest use in the Baltic countries.
The aim of this study was to examine whether the increased timber harvesting during the last decade has influenced the requirements of the Lesser Spotted Eagle (Aquila pomarina C.L.Brehm) for their nest-sites. In 2004, 7% of checked Lesser Spotted Eagle territories were disturbed by forestry operations. The general tendency was that the characteristics of stands used for nesting differed from the average forest stand characteristics in the landscape less than a decade ago.
Eagles were found to nest in 19 different forest types, while previously just 13 of such forest types had been recorded. Less productive forests (2nd site class) and normally irrigated stands were not avoided nowadays. The average age of nest stands decreased by 16 years. Though oak remained one of the most preferred nest-trees (20% of all cases), spruce became the most common one (48%).
This leads to the assumption, that the eagles are less selective nowadays than in the past. The increased timber harvesting during the last decade might explain why eagles switched to nest in stands, more similar to the surrounding forest landscape than in the past, and why some nest-site preferences remained and others disappeared. It is likely that during the next 30 years forest operations will be one of the most important factors, having an effect on the Lesser Spotted Eagle population in Lithuania.

30 samples of pellets of the Lesser Spotted Eagle collected in June–August 2004–2005 in 10 administrative districts of Lithuania were treated by osteological and hair analysismethods. Both methods complemented each other. The preying on thewater vole (Arvicola terrestris) and using of the carrion of Cervidae was confirmed only by hair analysis. The common vole (Microtus arvalis), short-tailed vole (M. agrestis), root vole (M. oeconomus) and yellownecked mouse (Apodemus flavicollis) were identified by osteological analysis only. The highest frequency of occurrence was characteristic of T. europaea (0.60), birds (0.53) and insects (0.30).AmongMicrotus voles, the highest FO was characteristic of M. arvalis (0.27) and M. agrestis (0.17). The employment of hair analysis added ca. 15%to the estimation of the biomass consumed. According to the numbers, the diet was dominated by Microtus voles (44.4%) and T. europaea (18.2%); according to the biomass consumed, the main diet items were T. europaea (40.2%) and birds (21.1%).

54. Flight strategies of migrating raptors; a comparative study of interspecific variation in flight characteristics. (1997)

Full text available as PDF: ... cteristics


The comparison of flight styles and flight parameters of migrating raptors in Israel revealed the following. (1) Climbing rate in thermal circling did not differ between species, indicating that chiefly the strength of thermal updrafts determined the climbing rate and that morphological features were less relevant. (2) In interthermal gliding, air speed was positively and gliding angle negatively related to the species' average body mass. Heavier species glided faster and had smaller gliding angles. (3) In soaring and gliding flight, cross-country speed relative to the air was positively related to the species' body mass; it was obviously the result of the gliding ability increasing with body mass. (4) Eagles and buzzards used soaring and gliding flight for more than 95% of the observation time. Additional soaring in a straight line whilst gliding was extensively used by the Steppe Eagle Aquila nipalensis, Lesser Spotted Eagle Aquila pomarina and Booted Eagle Hieraætus pennatus and even more frequently by the resident species, the Griffon Vulture Gyps fulvus and Shorttoed Eagle Circaetus gallicus. Smaller species, such as the Levant Sparrowhawk Accipiter brevipes, harriers (Circus sp.) and small falcons (Falco sp.). showed the highest proportion of flapping and gliding flight (9–33%). (5) In a comparison of the flight parameters and proportions of flight styles, a cluster analysis distinguished two main groups: The first consisted of Montagu's Harrier Circus pygargus, Pallid Harrier Circus macrourus, Levant Sparrowhawk and small falcons; their flight behaviour was characterized by both the high proportion of flapping and the low gliding performance. The second group comprised the typical soaring migrants: Steppe Eagle, Lesser Spotted Eagle, Booted Eagle, Steppe Buzzard Buteo buteo vulpinus, Honey Buzzard Pernis apivorus and Egyptian Vulture Neophron percnopterus, and they had very similar flight behaviour and were closely clustered. The Black Kite Milvus migrans and Marsh Harrier Circus aeruginosus were intermediate between typical soarers and flappers. The two resident species, Griffon Vulture and Short-toed Eagle, were grouped separately from the soaring migrants.
