Continuing on my rounds, I found the Sociable Plovers again, hunkered down between two crop lines and easily overlooked. The Merlin was also there, as were the obligatory Black Kites, Buzzards, Kestrels and Sparrowhawks. The northern fields were awash with larks again. This time I noticed three much larger larks in with a flock of skylarks. As they flew into land I saw the broad white trailing edge of the wings - Calandra larks! Sadly, no photos. The lark flocks were very skittish, presumably because two Hen Harriers were quartering the fields.
My attention was caught by an adult Eastern Imperial Eagle sitting on top of a distant tree. Very distinctive! It didn't allow for close inspection though and flew off at my approach.
A very different bird from the juvenile, below.
