Wow lovely capture. With the 100-400 you could get some of the habitat. Good that you got quite less vegetation blocking the yawn. Good details as I remember we were not expecting this and you shot hand held just pointing towards it. Nicely captured. Thanks for sharing.

Murugan, this was a yawn. It was basking in the morning sun, on seeing us it coiled, but after sometime it slowly came out and then suddenly it yawned.
