Excess N and P in water affect water quality.
- class="label">•
Birds nesting in colonies contribute significant loads of N and P to watersheds.

The contribution of N and P by colonial birds to watersheds in Texas is poorly known.

Concentrations of N and P in water were higher during the peak of the breeding season.

Large colonies (i.e. 20,000 birds) could release as much as 20 kg N and 2.3 kg P per day.
