After the Bulbul family left the nest, I removed the tar sheets covering the nest. I thought the predator bird would return (see Tragedy...) if it saw the nest & I didn't had to wait long to get results. It came right to the nest & was searching all over.
It was a magnificent bird with grey-blue coloured body & was very fast. I only managed to capture it's photo after it flew away to a distant tree.
This was a Shikra ('kurulugoya' in sinhala). A magnificently beautiful bird.
The scientific name is Accipiter badius.
It's a bird of prey. It's a small bird with short broad wings & long tail. It's found in South Asia & sub-Saharan Africa. It's prey include lizards, dragonflies, small birds & mammals.
