Some flies deserve a much closer look. Explore a few of our lesser-known but fascinating and - dare we say - beautiful fly species.

We've been watching the birds of northern Virginia very closely. Maybe too closely.

For the last four years it’s has been a pleasure and an honor to be NVBA’s president. I want to take this opportunity to thank the great folks on our board, on our staff, in our volunteer ranks, and among our members and communities – and to highlight how, working with these groups, NVBA has been able to strengthen and grow its bird and nature conservation efforts. 

The 2026 Winter Waterfowl Survey, sponsored by NVBA, was conducted on February 14 and 15. Nearly 70 participants monitored areas along the Potomac River from western Loudoun County to Quantico Marine Base in Prince William County.

National Geographic defines citizen science as “the practice of public participation and collaboration in scientific research to increase scientific knowledge.” Projects usually do not require specialized knowledge, and volunteers often train new ones.

The equinox is a reminder that things begin again. Birds feel it before we do, returning, singing, coming back to the spaces they need. And that's exactly what I want us to think about this May during spring migration and the local nesting season: who gets to be in those spaces with them?

It’s the time of year when more of us are spending time outdoors, watching and photographing birds. It’s also a good time to review the principles of ethical birding. 

Northern Virginia’s stream and river water quality is not great. Although agriculture is the largest contributor by far of nutrient and sediment loads in Virginia’s streams, rivers, and the Chesapeake Bay, urban and suburban stormwater runoff is the second-largest and the fastest-growing contributor to these pollutants.
