Dear @adrianobalan sir
Looks like a bird sparrow in the three beautiful photographs of the beautiful looking or small first. In the last photograph, I do not know much about yellow blue and white or small birds but I agree with you that small birds exist only for the sacrifice of big birds. Big birds prey on these birds. Although the existence of these birds in the rural areas is much safer. I always admire your great photography Thank you for providing information about the best wild birds and insects every day. thank you
