Анна Ясько: Похожа на самку белошапочной овсянки. Коричневатое на груди, по бокам более темные штрихи, на ушных кроющих светлое пятнышко.


Олег Белялов: Джунгарский Алатау очень богат на орлов Aquila - есть беркут, могильник, степной и даже большой подорлик...


Николай Балацкий: Малик, это гнездо южной бормотушки. Яйцо, возможно, болтун (если в гнезде следы от птенцов в виде помёта или перхоти).
