After 234,495 hours in the field, 3,525 volunteers documented breeding behaviors across 4.7 million observations, creating the most comprehensive behavioral dataset of North Carolina's breeding birds ever assembled—revealing not just where birds nest, but how they behave during their most critical life stages.

A Dark-eyed Junco pauses 47 seconds before approaching new water sources in restored wetlands. This hesitation reveals how birds adapt their behavior when familiar habitats transform. Understanding these behavioral shifts helps us predict which species will thrive in restoration projects and which need additional support.

More than 1 billion birds die from glass collisions in the United States alone each year. Black-throated Blue Warblers, Ruby-throated Hummingbirds, and Yellow-bellied Sapsuckers rank among the most vulnerable species to these fatal encounters with reflective surfaces.
