Do I need a GPS Unit when I go Birding?

This is part #16 in a series of frequently asked questions about birding.

What is a GPS and how do I use it in birding?

• GPS stands for Global Positioning System and relies on signals from satellites to give an exact fix as to where you are on the Earth, often accurate to within a metre or so.
  
• A GPS unit looks a bit like an older mobile phone or a remote control unit. They can be quite expensive with base models starting at about A$400.
  
• A GPS is useful when doing surveys that require latitude and longitude coordinates. When I was sending in reports for the Atlas of Australian birds this was a requirement and I also add this information to the database on my computer.
  
• A GPS is not essential unless one is doing some serious research or survey work – or you are a statistical freak tragic like me.
  

• They can also be useful if you get lost – if you remember to take a reading of where you left the car!

• Happy birding – and don’t get lost – or misplace your car!
