Our Trends Analysis Goals

02.

Prioritization

03.

Thank You to Our Monitors

One individual's contributions may seem small, but together we have created one of the most robust databases of regional bird sightings in the nation.

Your Work Has a Direct Impact on Helping Birds

This analysis would not have been possible without the data, insights, and spirit of this knowledgeable and dedicated field crew. Hundreds of BCN volunteer bird monitors have contributed countless hours in the field to consistently and painstakingly collect this data year after year.

If you aren't already a monitor for the BCN Survey, we hope that you will join us. Your contributions can help us identify important habitat, improve current management practices, monitor threats, set regional priorities, and work with land managers to protect areas where birds are breeding. Just two visits of a couple hours at a preserve each summer can provide a wealth of information for this effort.
