What is eBird ?
A real-time, online checklist program, eBird has revolutionized the way that the birding community reports and accesses information about birds. Launched in 2002 by the Cornell Lab of Ornithology and National Audubon Society, eBird provides rich data sources for basic information on bird abundance and distribution at a variety of spatial and temporal scales.
eBird’s goal is to maximize the utility and accessibility of the vast numbers of bird observations made each year by recreational and professional bird watchers. It is amassing one of the largest and fastest growing biodiversity data resources in existence. For example, in March 2012, participants reported more than 3.1 million bird observations across North America!
The observations of each participant join those of others in an international network of eBird users. eBird then shares these observations with a global community of educators, land managers, ornithologists, and conservation biologists. In time these data will become the foundation for a better understanding of bird distribution across the western hemisphere and beyond.
Bird Trax, a fun part of eBird
BirdTrax Recent eBird Data Explorer Gadget is a free project, created by active eBirders explicitly for providing all birders with easier access to recent eBird data. Here's a really quick schematic illustrating what you can do with this gadget:
