VABBA2 Handbook

The Atlas handbook describes all of the important protocols and procedures necessary for successful atlasing. Additionally, it provides background information about the project and partners who support the VABBA2.

Breeding Timeline Bar Charts

These charts show the typical start date and length of the breeding, migration, and non-breeding seasons, as well as transitional times, for birds breeding in the three major eco-regions of Virginia.  Transition times represent overlap between migration and breeding seasons and breeding codes should be used with care at these times. (Note: these are suggested timelines only and not to be taken as absolute.)
