About Bird mnemonics

I have often been asked by many, how do you remember so many bird calls. While experience matters (have been birding since 30 years), but some tricks do help to remember some bird calls..... one of them is about "Bird mnemonics". This video was recorded by @Nityanand Chowkidar (Ace Naturalist from Sunderbans, West Bengal) while I was explaining about Bird mnemonics during one of my trips to Sunderbans.
