Circaetus gallicus information navigator

The recently accepted article of Guilad Friedemann and others is a result of the study of interspecific interactions between Short-toed Eagles and Long-legged Buzzards and their breeding in the Judean Slopes /map/:

• Guilad FRIEDEMANN, Yossi LESHEM, Lior KEREM, Avi BAR-MASSADA & Ido IZHAKI, 2017 – Nest-site characteristics, breeding success and competitive interactions between two recently sympatric apex predators // Ibis. Accepted Author Manuscript. doi:10.1111/ibi.12498; the Supplementary online material – (En).

We offer you the summary (En) of the following article dedicated to sexing of Short-toed Eagle and Common Buzzard nestlings:

• Jalby V., Malafosse J. P., Nore T. et Wink M., 2012 – Détermination, par la biométrie, du sexe des poussins chez deux espèces de rapaces Circaetus gallicus et Buteo buteo. Comparaison avec les Autours des palombes Accipiter gentilis et les Buses variables adultes [Nestling sexing by biometric and molecular analysis in two diurnal raptors, Circaetus gallicus and Buteo buteo. Comparison with the Goshawk (Accipiter gentilis) and adult Buzzards] // Alauda, 80 (3): 187-202.

The biometric data on Short-toed Eagle nestlings were collected by Jean-Pierre Malafosse in Cévennes National Park /map/.

Two more articles on migration of Short-toed Eagles came out this year:

• Mellone U., Klaassen R.H.G., García-Ripollés C., Limiñana R., López-López P., Pavón D., Strandberg R., Urios V., Vardakis M., Alerstam T., 2012 – Interspecific comparison of the performance of soaring migrants in relation to morphology, meteorological conditions and migration strategies // PLoS ONE 7(7): e39833. doi:10.1371 / journal.pone.0039833 – (En).

• Frédéric Jiguet, Damien Chevallier, François Baillon, Julien Ventroux & Pascal Cavallin, 2012 – Sub-Saharan staging areas of a first-summer Short-toed Snake Eagle Circaetus gallicus // Bird Study, 59(1): 102-104. (En).

The first one is based on comparative data concerning Osprey, Marsh Harrier, Egyptian Vulture and Short-toed Eagle.
