I get to travel a lot in the richly biodiverse western ghats of India. While hiking, one of the most difficult tasks I face is to identify birds that I come across. I'm not a professional or even amateur bird watcher. However, my curiosity to know more about the birds that I come across makes me wonder if there is a handy resource which allows for identifying birds on the go. I own the "Birds of the Indian Subcontinent" field guide. This however is a super heavy book which is impractical to carry on a hike.
The alternative would be to click a pic and come back and research on the same. I would like to know what the members here do when it comes to identification of birds.
PS: I'm not looking for google as a possible solution. I want to know if there are field guides which are handy to carry. Or is it all based on click-come-back-and-identify?
