It's mid-October and reports from Oman are that many Steppe eagles have already arrived. Here is what our two tagged birds are doing...
162312 has migrated back to the exact location where it spent the winter of 2017-18, in central Saudi Arabia, about 180 km NW of Riyadh (Map below). It arrived there on 28 September. In 2017, it arrived in early November. Have a look: https://egyptianvultureoman.blogspot.com/2017/11/ It is not uncommon for birds to show fidelity to their wintering areas, though we have few data about this from Steppe eagle.
105 started migration on the 3rd of September, though we did not know about it until some days later when it came into GSM range. By 16 September it had made it to Soltanabad, near Ilam, Iran, where it has remained. At Soltanabad it has been able to download the many GPS locations it logged during the summer, when it had been mostly out of GSM range. Alireza Hashemi of the Tarlan Ornithological Society in Iran reports that there has been an outbreak of anthrax in that area that has killed many cattle, and so perhaps the eagle will stopover for some time more. However, we predict that it will eventually move farther south (map below).
