My two are Arabian golden winged grosbeck and Verreaux's eagle.
Ayn Hamran is one of the best places to see the former and the latter has been seen flying over there too.
I visit Ayn Hamran about three times a week mostly in the early morning but have had no success with these birds.
Ironically black-crowned tchagra was a Nemesis bird for me in Saudi Arabia but I see it regularly at Ayn Hamran without difficulty.
black crowned tchagra yesterday
Yesterday I saw three groups including one out in the open in a tree.
Another highlight from yesterday morning was a smart male Turkestan shrike. This is more evidence that some Turkestan shrike stay the winter (and not just Daurian shrike).
Arabian warbler from December 12th
Ayn Hamran is a good place to see Arabian warbler. I did so on every visit in December.

second view of spotted flycatcher
I will keep visiting Ayn Hamran. One day I will see the grosbeck even if I have to wait to the Khareef season when there are records of high numbers there.
