This is a very cool and Statewide opportunity for birders of all levels.

The Maine Bird Atlas has volunteers systematically collect data from a designated block. Anyone with an interest in birds who owns a pair of binoculars can be a part and can contribute records to the Maine Bird Atlas.  Regardless of the amount of time you have spent bird watching or even if you have just watched a certain nest found in your back yard your input can help the Inland Fisheries and Wildlife build their data compiled in Maine Breeding Bird Atlas. Novice birders are welcome and every sighting counts!

According to the IFW site there are 2 main ways you can contribute breeding bird records to the Atlas:

Incidental Observations:
Records of breeding birds, anywhere in Maine, are welcome and an important source of information.

Adopt and Survey an Atlas Block:
Take responsibility for surveying an Atlas Block. This need is particularly great in remote areas of Maine.

Their handbook says they hope that volunteers can offer up about 20 hours per block of data.  They also have contacts and a lot of information on how to get started. So whether you are a bird feeder enthusiast or you're ready to hit the road this could be a great summer adventure for the whole family.
