I kept a bird diary for about 36 years, involving several states and countries. I gave it up years ago, but still love the hobby.
A friend of mine just gave me a copy of the RSPB Handbook of British Birds. I am so pleased.
Many I know how to identify already. And, I owe it to my dad (HFD again) for this hobby.
Today's bird--Red-Legged Partridge.
If one memorizes the songs or chirps and knows the habitat, identification is much easier. I need to see another one, as I do not consider a bird seen by me unless I am absolutely sure...thanks to wiki for photo.
