Early birds

Do you know that birds have their ways of waking fellow birds up in the morning? Well, I didn't know that too until now. One bird starts chirping and all suddenly of them on the trees suddenly chirp together.

They are just outside my window at 6 am in the morning. I guess they are very disciplined lot. All woke up and start to work. I wonder if they need to groom themselves before leaving for 'work'?

Now that's one useful lesson I learnt by learning to wake up at 6 am. I know it is no big deal to wake at 6am. But I have just gone to bed at 3 am. KNNMCB!
