Collision between a migrating lesser spotted eagle (Clanga pomarina) and an aircraft as detailed by fine-scale GSM-GPS telemetry data

Abstract

We tracked a breeding adult female lesser spotted eagle (Clanga pomarina) from Germany using GPS technology, and provide details of her collision with a small aircraft at Rzeszów (SE Poland) during April 2016, when she was migrating towards her breeding territory. The ultimate fate of the bird was not established until the tag was found by chance and the data were recovered. Bird strikes are a global problem with sometimes lethal consequences for animals and people. This account highlights the way technology allows us to closely monitor events during bird migration, and document human-raptor interactions. The collision illustrates how food availability might affect bird-strike risk, and indicates that removing animal carcasses from the vicinity of airports could reduce that risk. We discuss the data in relation to risks faced by lesser spotted eagles (and other soaring birds) of collision with aircraft, especially along flyways during migration seasons.

Colour ringing of the Spotted Eagles (Aquila pomarina, Aquila clanga and their hybrids) in Europe - a review

During the years 2000-2008 1377 Spotted Eagles (SE) (Aquila pomarina, Aquila clanga and their hybrids) have been colour ringed in Europe. Out of these, 1303 (94.6 %) were young birds and 74 (5.4 %) were adults. Out of the total, 1290 (93.7 %) were the Aquila pomarina Lesser Spotted Eagles (LSE) - 1229 (95.3 %) young and 61 (4.7 %) adults, 50 (3.6 %) were the Aquila clanga Greater Spotted Eagles (GSE) - 44 (88.0 %) young and 6 (12.0 %) adults and 37 (2.7 %) were the Aquila pomarina x Aquila clanga hybrids (LSE x GSE) - 30 (81.1 %) young and 7 (18.9 %) adults. With respect to the individual European countries the following SE species and numbers were ringed: Slovakia 636 (46.2 %), Poland 333 (24.2 %), Estonia 153 (11.1 %), Germany 116 (8.4 %), Lithuania 68 (4.9 %), Latvia 45 (3.3 %) and Belarus 26 (1.9 %). In the article authors presents a review on Spotted Eagle colour ringing programmes running in individual European countries.
